Background. Legumes are usually consumed when physiologically mature, as dry seeds, however, flageolet beans seeds are also consumed immature. They are harvested when dry matter content is about 40%, pods are filled, grown, seeds succulent, showing green or light green colour and do not require lengthy thermal processing when prepared for consumption. Material and methods. The aim of this study...

The effects of blanching, freezing, and frozen storage on the retention of radical-scavenging activity (RSA), total phenolics, and ascorbic acid in bitter gourd were investigated. Blanching of sliced bitter gourd resulted in considerable losses of RSA and total phenolics, and most extensively, of ascorbic acid. In the subsequent frozen storage at -18 degrees C, RSA and total phenolic content of...

Vitamin C levels of commercially frozen okra, potatoes, green beans, broccoli, spinach and peas, including the impact of processing and storage, were studied. Depending on the vegetable type, prefreezing operations caused a 19.1–51.5% decrease in the initial vitamin C levels. The freezing process alone did not influence the vitamin levels except in the cases of green beans and spinach. Total lo...

in this study, ice-glazing process of frozen shrimp by chitosan was applied to protect the frozen shrimp from undesirable chemical and physical changes. the effects of 2% chitosan solution glazing on quality of whole, raw and cooked (without head, tail and shell) shrimps stored at -18±2ºc for 6 months were investigated and compared with water glazing, sodium metabisulfite treatment control. gla...

BACKGROUND Human breastmilk provides the best nutrition for infants. When women or infants have difficulties in breastfeeding directly, breastmilk is usually pumped and frozen for later use. However, while frozen, breastmilk may develop a rancid flavor, which induces infant feeding stress and raises the mothers' concerns about the quality of frozen breastmilk. Nevertheless, few studies have inv...

in this study the effects of gamma irradiation and frozen storage on sensory, chemical and microbial quality of fish fillets was investigated. hypophtalmyctis molitrix were equally divided to 12 fillests, then these 12 fillets were equally arranged in 4 groups (1-4). one group considered as control with no treatment and the other 3 groups was treated by 0.75, 3 and 5 kgy of gamma irradiation, r...

The study was designed to investigate the effect of duration of frozen storage on the chemical, microbiological and sensory profile of Tilapia fish (Sarotherodun galiaenus) collected from a research pond of the Agricultural Development Project, Akure, Nigeria, subjected to sixty days of frozen storage and analyzed at intervals of ten days. Protein content (%) ranges from 43.70 +/- 1.17-60.65 +/...

The effect of hypothermic storage on striped bass sperm calcium homeostasis was determined by Fluo-3 flow cytometry. Calcium homeostasis was defined as the ability of cells to maintain a low concentration of intracellular free calcium as measured by Fluo-3 fluorescence. Sperm were stored frozen in striped bass extender (SBE) and Tris-NaCl medium (T350) modified with 50 mM glycine and 7.5% dimet...

This study was conducted to evaluate the effect of frozen storage time (30, 60, 90 or 180 days) and cooking (100 °C, 30 min) on the physical characteristics and oxidative stability of M. Gastrocnemius pars interna (GN) and M. Iliofiburalis (IF) of rhea americana. Physical parameters measured included thawing and cooking loss, colour parameters (L*a*b*), while oxidation was assessed by determini...
