Effect of Storage Temperature and Materials on Protein Quality and Functional Properties of Soybeans

Future Postharvest and Food, EarlyView.
Hermetic PICS bags combined with cool storage (15°C) effectively preserved soybean protein quality and functional properties ([protein solubility, emulsifying capacity, and oil absorption capacity] of soybean protein isolates) during storage. Polypropylene bags and 25°C accelerated protein deterioration lead to significant nutritional losses.

Insect‐resistant soybean genotypes accumulate rutin and its O‐methylated derivative narcissin, a more potent flavonol targeting Anticarsia gemmatalis digestive and detoxification enzymes and reducing larval survival

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Soybean underpins Brazil's agricultural, yet its sustainability is threatened by lepidopteran pests such as Anticarsia gemmatalis. Although insect‐resistant cultivars have long been associated with the constitutive accumulation of quercetin‐derived flavonols, the biochemical mechanisms underlying this resistance remain poorly ...
