Structural changes of malt proteins during boiling.
Changes in the physicochemical properties and structure of proteins derived from two malt varieties (Baudin and Guangmai) during wort boiling were investigated by differential scanning calorimetry, SDS-PAGE, two-dimensional electrophoresis, gel filtration chromatography and circular dichroism spectroscopy. The results showed that both protein content and amino acid composition changed only slig...
متن کاملChanges in composition and thermal transition temperatures of grain sorghum wax during storage
Grain sorghum (Sorghum bicolor) wax is composed mainly of aldehydes, alcohols, and acids. Aldehydes, comprising about one-half of the wax, are readily converted to acids in presence of air. In this study, whole sorghum wax and an aldehyde fraction from sorghum wax were subjected to oxidative conditions. Changes in the major components and thermal transition temperatures were determined using HP...
متن کاملQuality changes in cocoyam flours during storage
Cocoyam tubers were subjected to two processing methods (fermentation and parboiling) and milled into flour. The samples were stored at 25°C, 35°C, and 45°C and analyzed at 2 weeks interval for 8 weeks for their nutritional, functional, and pasting properties. Data obtained were subjected to multiple analysis of variance. Storage period and its interactive effect with the processing methods had...
متن کاملChanges of fatty acid profiles in fillets of Cobia (Rachycentron canadum) during frozen storage
In this study changes in fatty acids profile during frozen storage at -18°C of Cobia (Rachycentron canadum), caught from the Persian Gulf (Bandar Abbas) were studied. Changes in saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs), polyunsaturated fatty acids (PUFAs), EPA+DHA/C16, n-3 PUFA/n-6 PUFA (n-3/n-6) and polyunsaturated fatty acids /saturated fatty acids (PUFA/SFA) were i...
متن کاملComparison of lipid changes in chicken frankfurters made by soybean and canola oils during storage
Two batches of frankfurters containing about 55% chicken meat with two different oils (including canola and soybean) were manufactured. Batch 1 included canola oil and Batch 2 included soybean oil in the products. Various analyses were performed to detect the lipid changes of both batches during storage. Fatty acid composition analysis using gas chromatography showed little change in the fatty ...
