    Opis:
    Spears or cladophylls are edible parts of asparagus (Asparagus officinalis L.) implemented in a human diet while its hard-stem by-products have been used for animal feeding. In this study, the asparagus hard-stem was proved to be rich in dietary fiber and total phenolics with high antioxidant capacity. Wheat flour was partially replaced by asparagus hard-stem powder (AHP) in the cracker recipe and the AHP ratios were 0 (control), 5, 10, 15, 20% of the blend weight; the nutritional constituents, antioxidant capacities, physical attributes, and sensory overall acceptability of crackers were then evaluated. As the AHP ratio increased from 0 to 20%, the dietary fiber and total phenolic contents of the fortified crackers were improved by 5.0 times and 3.2 times, respectively, while their ferric reducing antioxidant power and DPPH scavenging capacity were enhanced by 6.1 and 1.4 times, respectively. Besides, the elevated ratio of AHP also increased the product hardness and reduced its overall acceptability. The impacts of water amount used in the dough kneading on the high-fiber cracker quality were then investigated. At 20% AHP level, the appropriate water amount was 55 g/100 g of the flour blend to reduce hardness and improve overall acceptability of the fortified crackers. The study results show that AHP is a potential dietary fiber and antioxidant ingredient for high-fiber cracker making.

    Opis:
    The production of cashew apple juice generates fruit pomace which is rich in dietary fiber and phenolic compounds and shows high antioxidant capacity. In this research, the effects of different ratios of cashew apple pomace powder (CAPP) in the pasta formulation on the product quality were investigated. Increase in CAPP level in the pasta recipe from 0 to 20% enhanced the total dietary fiber and total phenolic content of the product by 4.1 times and 11.8 times, respectively, as well as improved the 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity and ferric reducing antioxidant power by 18.2 times and 28.6 times, respectively. Nevertheless, the increased level of CAPP in the pasta recipe resulted in decreased cooking quality, textural properties and overall acceptability of the pasta. Pasta sample with 10% CAPP level in the recipe was considered high-fiber food with acceptable sensory quality. Therefore, CAPP may be considered a promising source of dietary fiber and antioxidants for the development of healthy food products.

    Opis:
    Isoflavones in soybean have been well-known with many health-promoting effects on humans. This study aimed to purify isoflavones from the crude soybean extract by the static adsorption/desorption process on macroporous resins. A screening test of four commercial resins: D101, AB-8, Amberlite(R) XAD4, and Diaion HP20 according to their adsorption/desorption characteristic for isoflavones was investigated. All four resins showed high adsorption and desorption characteristics in which D101 resin was chosen as the most suitable resin for purifying isoflavones. Compositional analysis showed that daidzin and genistin were the main isoflavones in the crude soybean extract. The adsorption isotherms data of total isoflavones, daidzin, and genistin fitted well with the Langmuir model with R2>0.98. The dynamic adsorption conditions for the purification process of isoflavones on the D101 resin-packed column were selected at the bed volume (BV) of 200 mL, feed volume of 3.75 BV, and flow rate of 1.5 BV/h. The dynamic desorption was carried out with the elution solution of 70% (v/v) ethanol, elution volume of 2.5 BV, and flow rate of 1 BV/h. The total isoflavone content in the purified extract was 8.70-fold higher than its initial content in the crude soybean extract with a recovery yield of nearly 80%. The study results reveal a strong possibility for large-scale production of isoflavones for further application in functional food products or pharmaceutical products.

    Opis:
    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.

    Opis:
    Mulberry pomace powder, a by-product of mulberry juice processing, was added to pasta recipe to make pasta with high dietary fiber and antioxidant contents. The effects of mulberry pomace ratio on the nutritional, textural and cooking properties as well as the sensory overall acceptance of the product were investigated. A significant increment in dietary fiber and total anthocyanin contents as well as decrement in cooking quality, texture and color change were observed. The cooking loss increased with the substitution level of mulberry pomace while the optimal cooking time, swelling index and water absorption index decreased. The quality improvement of 10% mulberry pomace fortified pasta was investigated by adding a transglutaminase preparation with enzyme dosage from 0.25 to 1.00 U/g protein. The fortified pasta treated with transglutaminase at 0.50 U/g protein showed a significant improvement in chewiness, tensile strength and elongation rate but was not significantly affected in terms of the swelling index and water absorption. The use of transglutaminase also improved the overall acceptability of the fortified pasta. Mulberry pomace powder may, therefore, be considered a potential antioxidant-rich and dietary fiber-rich material for incorporation into pasta products.

    Opis:
    Purified and crude proteases have been broadly applied to obtain hydrolysates from soy protein isolate (SPI) with the improved functional and biological properties. However, the use of fruit juices containing native proteases to produce SPI hydrolysates with better bioactivities receives less attention. The present study attempted to investigate the ability of papaya (Carica papaya) and cantaloupe (Cucumis melo) juices in the hydrolysis of SPI and assess the antioxidant, anti-tyrosinase, and wound-healing activities of obtained hydrolysates. Our analysis showed that SPI was hydrolysed by papaya juice, at the juice to substrate ratio of 2.5:2 (v/w), with a degree of hydrolysis (DH) of approximately 11% after 4 h of treatment at 55ºC. A higher DH (about 26%) was obtained by the hydrolysis with cantaloupe juice at the same juice to substrate ratio and treatment conditions. Papain used at the enzyme to substrate ratio of 0.625:2 (w/w) broke down SPI in a similar DH as papaya juice at the juice to substrate ratio of 2.5:2 (v/w). The ABTS•+-scavenging, •OH-scavenging and tyrosinase inhibitory capacities of SPI were lower than those of hydrolysates obtained by the treatment with papaya juice (IC50 of 2.39, 7.17, and 32.07 μg/mL, respectively) and cantaloupe juice (IC50 of 2.46, 6.93, and 30.49 μg/mL, respectively). An enhancement in ABTS•+-scavenging, •OH-scavenging and anti-tyrosinase activities was also observed in the hydrolysate obtained by papain (IC50 of 2.75, 17.85, and 117.80 μg/mL, respectively) compared to SPI. However, the increased level of the •OH-scavenging capacity of the hydrolysate obtained by papain was lower than that of the fruit juice-treated samples. Remarkably, the hydrolysates prepared from the hydrolysis with fruit juices accelerated the wound closure in human fibroblasts by estimately 1.5 times after 24 h of treatment while this property was not observed in the hydrolysate by papain. Our study data suggest the potential of SPI hydrolysates obtained by papaya and cantaloupe juices in the preparation of healthy food products.
