Ageing of Stored Rice: Changes in Chemical and Physical Attributes
Rice ageing is a complicated process, which involves changes in physical and chemical properties of the rice grain. Starch, protein and lipids are the main rice grain components which affect cooking and eating quality. While the overall starch, protein and lipid contents in the rice grain remain essentially unchanged during storage, structural changes do occur. These changes affect the pasting ...
متن کاملChemical and nutritional changes in stored herring meal
This study was designed to investigate the nutritional significance of the interactions that may occur between oxidized fat and proteins in foods. Herring meal, because of its high content of protein and of highly unsaturated fat, was chosen as the material for study. The first two papers in the series (Lea, Parr & Carpenter, 1958, 1960) dealt mainly with factors influencing the rate of oxidati...
متن کاملChemical and nutritional changes in stored herring meal
That the protein of foods can suffer loss of nutritive value as a result of overheating during processing is well known, and Carpenter, Ellinger, Munro & Rolfe (1957) have reported the effects of heating under various conditions on the nutritive value and available lysine of the protein of fish meal. It has been shown also that interaction between proteins and reducing sugars can occur during s...
متن کاملChemical and nutritional changes in stored herring meal. 2.
In the first paper of this series (Lea, Parr & Carpenter, 1958) we reported the results of experiments on the effect of storage on the nutritive value of herring meal as a source of protein for chicks. Over a period of 24 months’ storage in air there was extensive oxidation of the lipids, but only a very small drop in ‘available’ lysine (lysine with a chemically reactive E-NH, group) and no sig...
متن کاملComposition of herbage in Pinus roxburghii Sargent stands: basal area and importance value index
In the present study basal area and Importance Value Index (IVI) attributes of herbage were investigated in chir pine (Pinus roxburghii Sargent) stands of three different ages and also in open grassland in the sub-tropical region of Himachal Pradesh (India) during growing season (June to September). A higher basal area of the herbage was recorded in open grassland as compared to chir pine stand...
