Opis:
Quantitative descriptive analysis, consumer acceptability as well as physicochemical characteristics were employed to analyse the effect of ground chia seeds on the texture and quality of wheat bread. Chia seed oil changes and its impact on selected characteristics were determined. The share of chia seeds did not contribute to bread quality deterioration. The addition of 7.5% chia seeds significantly reduced consumer acceptance as well as contributed to the development of undesirable features in the sensory profile, including fatty, rancid, and off-flavour. The share of chia seeds in an amount not exceeding 5% did not deteriorate the overall quality of bread. The composition of fatty acids of bread with chia seeds, especially with their 5 and 7.5% addition, could be valuable from the nutritional point of view. The fatty acid profile of bread with 5 and 7.5% chia seeds was characterised by over 50% higher polyunsaturated fatty acids to saturated fatty acids ratio compared to wheat bread. The n-6/n-3 ratio in the fatty acid profile of wheat bread was 18.77, while in the fatty acid profile of chia seed bread it ranged from 1.42 to 0.67. Oil extracted from bread exhibited better quality features as compared to oil extracted from chia seeds and subjected to the oxidative stability test.

Opis:
This study was carried out to evaluate the effects of sesame (Sesamum indicum L.) oil cake on pasta processing and the functional characteristics of the end product. The pasta produced from wheat flour fortified with 5, 7.5, 10, 12.5, and 15% (w/w) sesame oil cake showed a significant increase in total protein (i.e., ranging from 12.3 and 16.0 g/100 g), lipid (i.e., 3-fold) and crude fiber (i.e., 0.58 to 0.91 g/100 g) contents with the increasing addition of sesame oil cake. Consistograph tests showed that the pressure maximum decreased significantly from 267.2 kPa for the wheat flour dough (control) to 157.6 kPa upon the addition of 15% (w/w) sesame oil cake to wheat flour. Drop-in pressure after 250 and 450 s was lower for the control sample than for those containing 5, 7.5, 10, 12.5, and 15% (w/w) sesame oil cake. The elasticity value for the control dough was 500.1 Pa, and it was reduced to 392.3 Pa with the addition of 15% (w/w) sesame oil cake to wheat flour resulting also in a significant reduction in the extensibility. The pasta from the flour blend with 7.5% (w/w) sesame oil cake exhibited the highest cooking loss, at 5.40 g/100 g. Sensorial evaluation of the flavor and stickiness of pasta produced from the flour blends containing up to 10% (w/w) of sesame oil cake was satisfactory and recommended to open the door for industrial utilization of such valuable and nutritious by-products. Sesame components and gluten network interactions are believed to play a key role in modifying pasta’s functional characteristics and require more investigation.

Opis:
Consumers around the world are choosing sustainable and unprocessed foods. Roe deer meat, due to the natural origin, is a source of organic and healthy meat. The selection of suitable storage conditions and times plays an important role in a deterioration of the meat's functional and nutritional values. The knowledge about oxidation processes in roe deer meat stored and packed deploying different methods is limited. The main aim of this study was therefore to investigate the effect of storage method on the physicochemical properties of musculus longissimus thoracis et lumborum (LTL), musculus biceps femoris (BF), and musculus vastus lateralis (VL) of roe deer. The muscles were stored either dry (DRY-AGED), vacuum-packed (VAC), or packed under modified atmosphere (MAP) for 21 days. The quality of roe deer meat was assessed based on chemical composition, technological properties, pH values, water activity, colour, and oxidation processes of proteins and lipids. Roe deer meat had high protein (216.5–228.6 g/kg) and low fat content (17.1–25.8 g/kg). Both DRY-AGED and VAC contributed to improving meat tenderness during storage, while the Warner–Bratzler shear force of the MAP muscles increased. The high-oxygen conditions during MAP storage strongly induced the oxidation processes; an average increase of 1263% for thiobarbituric acid reactive substance (TBARS) level and 155% for protein carbonyl content on day 21. Vacuum packaging and dry-ageing are recommended methods for storing roe deer meat. The high oxygen atmosphere negatively affected the quality of this game species. It carries the risk of increased oxidation of proteins and lipids which may promote the formation of potentially detrimental compounds.

Opis:
The instant foxtail millet was prepared using microwave vacuum drying (MVD), microwave-hot air drying (MHAD), hot air drying (HAD) and traditional roasting (TR). Their effects on drying kinetics, physicochemical properties as well as sensory quality were evaluated and compared. Results showed that the total drying time varied with the drying method used and was about 160, 100, 260, and 45 min for MVD, MHAD, HAD and TR, respectively. The effective moisture diffusion coefficients (Deff) were 6.57×10-9 m2/s, 9.80×10-9 m2/s, 4.14×10-9 m2/s and 6.20×10-9 m2/s for MVD, MHAD, HAD and TR, respectively. Drying resulted in a significant decrease in L* and an increase in a* and b* of the color of products. MVD, MHAD and HAD products had a comparable rehydration ratio and cooking time. Scanning electron microscopy and rehydration process revealed that MHAD and MVD samples had a similar structure with the HAD sample. Drying caused a loss of 6.5–54.9% in the total phenolic content and a loss of 38.4–62.2% in total yellow pigment content. MVD millet displayed the highest total phenolic content (142.56 mg GAE/100 g dry matter) and yellow pigment content (9.56 mg CE/kg dry matter). In sensory evaluation, MHAD, HAD and MVD samples had comparable scores and were all accepted by the panelists, either in dry or rehydrated form. MHAD and MVD can be used as an alternative to hot air drying or traditional roasting in the production of the instant millet due to shorter drying time and better product quality.

Avocado pulp is low in sugar contents but quite high in dietary fiber, nutrients, and phytochemicals with potential health benefits. In this study, the avocado pulp was incorporated into ice cream. The effects of replacing milk fat with avocado on the physical and chemical properties of ice cream and consumer acceptability were evaluated. Milk fat-based ingredients of the ice cream were partially replaced with avocado pulp at ratios of 10, 20, and 30% (w/w). All ice creams were subjected to physical and chemical analyses and were evaluated in sensory acceptability tests. Replacing milk fat with avocado pulp significantly reduced moisture content, protein, and fat content, while it increased the carbohydrate (3.70 to 7.91 g/100 g) and crude fiber content (0.39 to 1.38 g/100 g). A higher content of avocado pulp caused a reduction in overrun and retarded the melting rate due to the effect of high fiber content. Increased viscosity and hardness were observed. The ice cream with the highest avocado pulp content had approximately 3-fold higher total phenolic content determined by the Folin-Ciocalteau method and 2-fold higher antioxidant capacity evaluated as DPPH• and ABTS•+ scavenging activity, and ferric reducing antioxidant power compared to that of the control. Sensory evaluation showed the 20% (w/w) avocado pulp was the suitable ratio for incorporating in the ice cream, which showed a good level of overall acceptability. Thus, our results suggest the potential use of avocado pulp to replace milk fat in frozen dairy products.

Opis:
Health-conscious consumers are interested in products with an increased bioactive compound content. The nutritional quality is considered both as a stability and bioaccessibility concern. The aim of this study was to investigate the effect of horseradish products (horseradish root pomace, horseradish leaf pomace, microencapsulated horseradish root and leaf juice) on the physicochemical properties of biscuits, as well as to assess in vitro bioavailability and activity of phenolics. The bioactive compounds and antioxidant activity of horseradish products, which were used to replace the flour in biscuit dough, were analysed. Physicochemical parameters (pH, water activity, colour, phenolic compound contents, and antioxidant activities) were determined for the biscuits. Horseradish products compared to other cruciferous vegetables have a high content of phenolic compounds, as well as high antioxidant activity. Higher levels of bioactive compounds were found in microencapsulated horseradish leaf juice, compared to the other horseradish products used in the study. Enriched biscuits had a significantly higher total phenolic content (TPC) and antioxidant activity, compared to the control. After 180-day storage, TPC of biscuits with horseradish root products did not change significantly but in biscuits with horseradish leaf products it decreased by 27–29%. The bioaccessibility index of phenolic compounds after in vitro digestion of enriched biscuits ranged between 2.19 and 2.99. Microencapsulated horseradish leaf juice was more effective in enriching biscuits with bioactive compounds. The developed biscuits enriched with horseradish products could meet consumer expectations for healthy, functional food.

Opis:
Starch is extensively used in the food industry as a texture modifier, a fat substitute, and in other applications. To optimise starch functional properties for specific use, it is subjected to various modifications. High-voltage electrical discharge (HVED) treatment, as a non-thermal and rapid process, was applied in this research as a single method and in combination with phosphorylation in order to explore its potential for improving starch physicochemical properties. Maize, wheat, potato, and tapioca starches were modified, and Na5P3O10 and Na2HPO4 were used for phosphorylation. Starch gelatinisation parameters (by DSC); paste clarity; and contents of amylose, damaged starch, and resistant starch were determined; and FTIR-ATR spectra were recorded. All modifications reduced the enthalpy of gelatinisation and decreased contents of amylose, resistant starch, and damaged starch. The effect of the HVED treatment on starch properties depended on starch type and combinations with chemicals. HVED could act as an aid in the starch phosphorylation process since the properties analysed were more effectively improved when HVED was combined with phosphorylation than by phosphorylation alone.

Opis:
In this study, the physicochemical properties, antioxidant capacity, sensory properties, and phenolic and mineral profiles of instant rosehip teas prepared using spray-drying (SD) and freeze-drying (FD) were compared. The yield of instant tea produced using FD and SD was 23.75 and 21.25 g/100 g, respectively. The total color difference between the FD and SD tea was 50.74, with the SD sample exhibiting higher redness and yellowness. The FD tea was richer in ascorbic acid than SD tea (67.2 and 59.4 mg/100 g dry weight, DW, respectively). The mineral content ranged from 0.20 mg/kg DW (copper) to 2,837 mg/kg DW (potassium) in SD tea, and from 0.31 mg/kg DW (copper) to 3,083 mg/kg DW (potassium) in FD samples. The total phenolic content was 1,315 and 1,495 mg GAE/100 g DW of SD and FD samples, respectively. The antioxidant capacity of instant rosehip teas was determined as total antioxidant capacity, ferric reducing antioxidant power and DPPH radical scavenging activity. In all these assays, FD tea was found to have a higher antioxidant capacity. In the phenolic profile determined by liquid chromatography-tandem mass spectrometry (LC-MS/MS) technique, protocatechuic acid dominated in instant rosehip teas prepared using both methods. The main flavonoids identified were quercetin, quercitrin, hyperoside and luteolin 7-glucoside. Following the sensory analysis, the panelists have generally preferred the FD tea in terms of aroma and flavor, while opting for the SD tea in terms of appearance and color. In conclusion, although freeze-drying allowed obtaining a product with a higher antioxidant capacity and antioxidant content than spray-drying, both drying methods may be considered suitable for the production of instant rosehip teas and ensure obtaining a functional food product.

Acerola seeds are a by-product of the food industry, which is rich in dietary fiber and antioxidants. This study evaluated the effects of cellulase treatment conditions, including the initial moisture content, enzyme dose, and incubation time, on the insoluble, soluble, and total dietary fiber content of acerola seed powder (ASP). The blends of wheat flour with untreated and cellulase-treated ASP (0, 10, 15, 20, 25, and 30%, w/w) were then used to produce cookies. The suitable conditions for the enzymatic treatment were the initial moisture content of 6 g/g dry weight (DW), an enzyme dose of 10 U/g DW and incubation time of 90 min. The cookies produced from flour blends with ASP had higher dietary fiber, ascorbic acid and total phenolic contents, and antioxidant capacity, compared to the control cookies without ASP. Phytate content in the cookies obtained with the lowest level of fortification (10%, w/w) was similar to that in the control cookies. The use of cellulase-treated ASP resulted in a lower ratio of insoluble to soluble dietary fiber in the cookies compared to when the untreated ASP was used. In addition, the cookies with cellulase-treated ASP had lower hardness and higher fracturability values than those fortified with the untreated ASP. The overall acceptability of the cookies produced with ASP was higher or comparable to the control cookies. For the first time, the low-cost ASP was used to improve the nutritional quality of cookies. The treated ASP is a novel promising dietary fiber- and antioxidant-rich ingredient for cookie preparation.

The objective of this study was to investigate the effects of modification by heat-moisture treatment (HMT) combined with microwave pre- and post-treatment (MW) on the physicochemical, structural and digestive properties of potato starch. The light microscopy, scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD) were used to determine the structural properties of starch. FT-IR and XRD spectra implied that MW and HMT destroyed the double helices and crystalline structure of potato starch. The relative crystallinity of modified starch granules (15.17–18.17%) was lower than that of native starch (19.39%). In the case of physicochemical properties, the modified starches had higher pasting temperature (68.8–93.0oC) and setback viscosity (807–3168 cP), but lower peak viscosity (1315–3662 cP) and breakdown viscosity (17.3–78.3 cP) than that of native potato starch, which were 68.5oC, 496 cP, 6598 cP and 2526 cP, respectively. The HMT and MW modifications significantly increased the content of slowly digestible starch and resistant starch. The resistant starch content of starch obtained by HMT combined with MW post-treatment was significantly higher than that of starch obtained by HMT combined with MW pre-treatment and single HMT. These results may promote good understanding of the effects of HMT combined with MW pre- and post-treatment on physicochemical properties and digestibility of potato starch, and wide utilization of microwave and heat-moisture techniques in starch modification.

The aim of this study was to evaluate the influence of selected processing conditions of beetroot spontaneous fermentation, including slice thickness (2, 4, and 6 mm), temperature (15, 20, and 25oC) and fermentation time (1-15 days), on the physicochemical properties of the resulting leaven (total soluble solid content, turbidity, pH, titratable acidity, color parameters, and content of total carbohydrates, total phenolics, total betacyanins and total betaxanthins). All tested conditions had a significant impact on the properties of beet leaven. Among them, fermentation time and temperature were mostly decisive. Slice thickness was important only for short-time fermentation. The preferable pH below 4.1 was achieved between the 4th and 6th day of fermentation, depending on process temperature. Titratable acidity steadily increased and pH decreased throughout the fermentation process, with more pronounced changes observed at the highest temperature. The highest values of total soluble solids (7.25%) and turbidity (1,100 NTU) were noted on the 13th day of fermentation of the thinnest slices at lower temperatures (15oC and 20oC, respectively). The color of the leaven darkened with increasing fermentation time, but the changes in the b* parameter were the most notable. Changes in the content of bioactive compounds were dynamic during beetroot spontaneous fermentation, but higher temperatures promoted increased total phenolic content and total betaxanthin content in the leaven. The optimal fermentation conditions in terms of all tested leaven properties were determined at 6 mm, 20oC and 7 days for slice thickness, temperature and processing time, respectively.

Opis:
The food industry is committed to supplying nutritious products that are attractive and convenient for consumers. Freeze-dried fruit and vegetable snacks that exemplify such products are difficult to obtain since it is necessary to use a carrier agent (usually a hydrocolloid ingredient) which meets the requirements of a sustainable development conceptual framework. Therefore, research has been undertaken to replace such a carrier agent with food waste fruit pomace. This study compared selected physicochemical properties of freeze-dried vegetable snacks obtained through the addition of sodium alginate and dried apple pomace powder in terms of the viability of replacing hydrocolloid carrier agents in freeze-dried products with fruit pomace. Three vegetable sets containing: yellow bean, carrot and potato were prepared and modified by adding diverse carrier agents. Snacks with the addition of dried apple pomace powder featured higher dry matter content and true and apparent density, but sodium alginate-structured products were harder and more porous. Dried apple pomace powder improved the health-promoting properties of the snacks, such as total phenolic content and antioxidant capacity. The type of additive also affected the internal structure of the products. The results indicate that the application of both dried apple pomace powder and sodium alginate as carrier agents can result in snacks characterised by repeatable quality, but it is unclear whether the total replacement of hydrocolloid is sustainably efficient.

The values of texture properties (firmness, brittleness, and cohesiveness) and colour parameters (values of b* and the yellowness index) of WB were lower than MB. The sensory analysis showed lower values of consistency descriptors (firmness, brittleness, cohesiveness), a less intense nutty and milky aroma, and a more intense cheesy aroma and taste in WB than in MB. WB was more abundant in monounsaturated, polyunsaturated, and long-chain FAs, including C18:0, C18:1 Σt, C18:1 Σc, C18:2, C18:3, and C18:2 c9, t11, and it was less abundant in saturated and medium-chain FAs, including C10:0, C12:0, C14:0, C14:1, C15:0, C16:0, and C16:1, relative to MB. Water content (MB vs WB and the corresponding fats) and thermal history (single vs repeated heating and cooling treatments) affected differential scanning calorimetry curves and phase transition peaks. The principal component analysis revealed that the FA profile influenced the crystallisation and melting peaks of MB fat (MBF) and WB fat (WBF). WBF crystallisation occurred at a lower temperature, was characterised by lower enthalpy, and proceeded more rapidly than MBF crystallisation. Various fat fractions had different melting characteristics, and most WBF fractions were characterised by lower melting enthalpy and a smaller maximum difference in heat flow than MBF. Whey butter and milk butter differed in physicochemical properties and sensory attributes, and their thermal profiles depended on the FA profile, water content, and thermal history.

Opis:
The aim of this study was to evaluate the possibility of using insect flour for sponge cake supplementation. Consumer acceptance, chemical composition, textural properties, and microbiological characteristics were determined. The addition of mealworm flour significantly increased the content of nutrients, especially protein, ash, lipid, and dietary fiber. Mealworm flour influenced the color parameters as well as textural properties. The fatty acid profile was dominated by monounsaturated fatty acids, ranging from 9.72 g/100 g for wheat flour sponge cake to 41.82 g/100 g for sponge cake with 20% addition of mealworm flour. The amino acid profile of mealworm flour was characterized by a significantly higher content of essential amino acids compared to wheat flour and sponge cakes. Sponge cake supplementation resulted in a good nutritional value of protein except for lysine which was the limiting amino acid in all samples. However, the limiting amino acid index was 63.04-63.10% compared to 30.38% for the mealworm and wheat sponge cake, respectively. The presence of insect flour reduced the organoleptic properties of the obtained sponge cakes, regardless of its quantity. The addition of mealworm flour contributed to a significant reduction in the hardness and fracturability of the sponge cakes on the baking day and during the 30-day storage. Insect flour addition did not reduce the microbiological safety of the final product. The study results indicate the possibility of using mealworm flour in the production of confectionery products.
