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.

Opis:
Several cereal species are grown in Europe, but wheat and maize have the largest acreage, followed by barley, oats and rye. Due to breeding improvements, cereal cultivars produce high grain yields. Improvement of cereals within a species and breeding of new cultivars is one of the main methods to improve yield and grain quality. However, the creation of interspecific hy- brids, in which new types with better characteristics are obtained through introgression and genetic selection, is also worthy of at- tention. The interspecific hybrids of cereals are not very popu- lar, but triticale is the cereal that has gained the most popularity and is of increasing interest to farmers in Europe. It is the result of the hybridisation of wheat and rye. Having many beneficial properties, its cultivation should be popularised. The aim of this paper was to review scientific research concerning possibilities of increasing the acreage under cultivation of this cereal, taking into consideration its agronomic requirements and grain quality, as well as the potential of grain utilisation for food and fodder purposes.

Opis:
Skipjack tuna (Katsuwonus pelamis) liver (TL) contains high-quality proteins which can potentially serve as an excellent source of functional protein ingredients. Thus, this study was conceptualized to evaluate the physicochemical, functional, and biological properties of proteins from TL using the pH shift process. The pH shift process was conducted through solubilization of TL at pH from 1.5 to 12.5, and the solubilized proteins at pH 2.5, 3.5, 10.5 and 11.5 were precipitated at pH 5.5. Finally, the tuna liver protein powders after the processes at pH 2.5 and 11.5 (TLP 2.5 and TLP 11.5, respectively) were obtained by freeze-drying, i.e. those with the highest extraction and protein recovery yields under acidic and alkaline conditions. Protein and lipid contents of TLPs were higher and lower, respectively, compared to the TL powder (control). Glutamic acid, aspartic acid, and alanine were prominent amino acids found in both TLPs. Foaming properties and water/oil holding capacity were higher in TLP 11.5, while protein solubility and emulsion properties were greater in TLP 2.5 compared between groups. Additionally, the DPPH• and ABTS•+ scavenging activities, as well as the angiotensin I-converting enzyme inhibitory activity, were remarkably higher in TLP 11.5 than in TLP 2.5. On the other hand, significant ferrous-ion chelating activity was observed in TLP 2.5. In conclusion, TLP 11.5 could serve as an alternative functional protein ingredient that provides essential amino acids, functional properties, and bioactivities.
