[Method] A kind of compound beverage was prepared with winter jujube and peanut meal, and its antioxidative activity was detected and its best storage conditions were determined. [ Result] The capacity of the compound beverage stored for 20 d to scavenge · OH, DPPH · and nitroso was the highest at freeze conditions, then followed by the refrigeration conditions, room temperature storage and sunlight. The total reducing capacity of the products was the highest under freezing conditions while the lowest under sunlight when some active components were destroyed. [ Conclusion] It is the best to store the compound beverage of winter jujube and peanut meal at freeze conditions and better at the refrigeration conditions. The storage of compound beverage should avoid direct sunlight. Key words Winter jujube; Peanut meal; Compound beverage; Antioxidation; China展开更多

The snacks were Buckwheat-Peanut Meal-Kale (BPK), BPK-Garlic, BPK-Onion and BPK-Ginger. Peanut meal was utilized to increase the protein content of these snacks as well as to add value to this agricultural byproduct. Snack dough was prepared using water nearly 1:1 as other as is ingredients. About 20 g of snack dough was placed on preheated KrumKake Express 839 Baker and cooked for 2 minutes. Sixty-nine in-house volunteers judged Color/Appearance and Texture/Mouth feel to be similar for the snacks tested. Taste/Flavor for BPK, BPK-Garlic and BPK-Onion snacks was similar and significantly higher (p ≤ 0.05) than for BPK-Ginger snacks. Odor/Aroma for BPK-Garlic snacks was significantly higher than for BPK-Ginger snacks. Acceptance for BPK and BPK-Garlic snacks was significantly higher than for BPK-Ginger snacks. Ex-pansion 3.6 - 4.2, porosity 0.72 - 0.75 and water activity 0.35 - 0.38 suggests that the snacks tested were light, crispy and have good anti-microbial stability. Acceptance was BPK and BPK-Garlic 94%, BPK-Onion 86% and BPK-Ginger 78%. These snacks contained only 3 - 4 ingredients and could be made in any house hold kitchen and/or in commercial production. Acceptance of 78% - 94% is very desirable. These whole grain gluten-free high protein vegetable healthy nutritious tasty snacks offer choice for all consumers, including individual’s sensitive to gluten.展开更多

DPMF at 5, 10, 15 and 20% was used to partially replace wheat flour in biscuits formulation and biscuits thus made were evaluated for nutri- tional composition, physical characteristics and sensory quality. Chemical analysis of DPMF showed 30.26% crude protein, 10.1% crude fat and 43.65% carbohydrates. The protein content increased nearly 1.5 times in biscuits as a result of incorporated DPMF, coupled with increase in ash content. The force required for breaking biscuits decreased with DPMF addition. On a 9-point hedonic scale, the highest overall acceptability score of 8.6 was obtained with 5% fortifi- cation, which was similar to control (8.8). Results demonstrated that biscuits made up of 15% DPMF exhibited all the values within an acceptable range.展开更多
