Finger millet for food and nutritional security
Finger millet is amongst the major crops of Uttaranchal. Over the years there has been rapid decline both in production and consumption of millets. Chemical composition of finger millet revealed that total carbohydrate content of finger millet has been reported to be in the range of 72 to 79.5%. Finger millet has nearly 7% protein but large variations in protein content from 5.6 to 12.70% have been reported by various...

Effects of polyethylene glycol 6000 and tripotassium phosphate on protopectinase partition in the aqueous two-phase systems using response surface methodology
The quantitative effects of polyethylene glycol (PEG) 6000 and tripotassium phosphate on protopectinase partition in the aqueous two-phase systems were investigated using response surface methodology. With an increase in PEG 6000 less than about 3.6 g protopectinase partition increased and decreased later beyond about 4.75 g. Furthermore, protopectinase partition improved continually and reached the maximum with...

Effect of cross linking on the physicochemical properties of cola starch
Cola starch from Cola nitida (rubra) was isolated using 1% (w/v) sodium metabisulphite solution and was chemically modified with sodium tripolyphosphate (STPP) and acetic anhydride (ACOH) as cross-linking agents. The physicochemical and functional properties of the cross linked (modified starch) were compared with the native (unmodified) cola starch. The results presented important changes in the pasting, thermal...

Consumer acceptability of four products made from beta-carotene-rich sweet potato
Beta-carotene-rich (orange-fleshed) sweet potato is one of a few new crops, which is an excellent source of energy and important nutritive substances that can contribute to improve the nutrient status of communities. The crop is being promoted in the developing world as a source of provitamin A towards alleviating vitamin A deficiency (VAD). The purpose of the study was to determine the consumer acceptability of...

Evaluation of aflatoxin content of naturally occurring molds from poultry feeds
Five different samples of poultry feeds were obtained from two different markets in Ibadan, Oyo State. These are broiler starter, broiler finisher, grower mash, layer mash and chick mash. The mycological analyses were carried out for the identification of molds naturally contaminating different poultry feeds. Also, aflatoxin concentration was determined. The fungi isolated include Aspergillus...
