Edible film is a thin layer that used as substitute for synthetic plastic or primary packaging of food product. Corn starch suspended with chitosan and glycerol able to improve the quality edible film. The purpose this research determine physical characteristics from modified corn starch. concentrations were 15%, 20% 25%, 30% 40%. Physical observed thickness, absorption, solubility degradation....

The need for sophisticated component therapy has resulted in improved techniques for obtaining concentrates of platelets and granulocytes. The use of single donors as a source for these products is advisable to avoid multiple sensitizations. A method for obtaining large quantities of platelets has been established rather easily. Obtaining concentrated granulocytes represents a greater problem o...

C57BL/6J-Min/+ mice, which are heterozygous for a non-sense mutation in the Apc gene, provide a model for both familial adenomatous polyposis and sporadic colon cancers. In our study, gut tumors and small intestine lymphoid nodules were counted in Min mice fed fiber-enriched diets for 6 weeks. Neither starch-free wheat bran nor resistant starch modified the number of tumors. However, short-chai...

The effect of increasing ageing time (t) of starch on the activity of three amylolytic enzymes (Termamyl, San Super, and BAN) was investigated. Although all the enzymatic reactions follow michaelian kinetics, v(max) decreased significantly (P < 0.05) and K(M) increased (although not always significantly) with the increase in t. The conformational changes produced in the starch chains as a conse...

Cereal Chem. 84(5):527-531 Rice starches of long grain and waxy cultivars were annealed (ANN) in viscosity peak heights, lower setbacks, and greater swelling consistency. excess water at 50°C for 4 hr. They were also modified under heat-moisThe modified starch showed increased gelatinization temperatures and tore treatment (HMT) conditions at 110°C with various moisture contents narrower gelati...

The action of some detergents on the incorporation of glucose from uridine diphosphate glucose or adenosine diphosphate glucose into the potato tuber starch grain was studied. It was found that the cationic detergent, cetyltrimethylammonium bromide, produces a rapid binding of both sugar nucleotides to the grain and a great increase in the incorporation of glucose into the polysaccharide. Kinet...

Pigment production by group B streptococci (GBS) is a useful test for identification of the organisms. The test is positive in 99.5% of beta-haemolytic strains. No false-positives are noted. Non-haemolytic strains do not produce pigment. Islam's media less agar can be used as a one-step broth detector of GBS in mixed cultures. This may have application for the detection of GBS in women in labou...

Potato tubers are modified stems that have differentiated into storage organs. Factors such as day-length, nitrogen supply, and levels of the phytohormones cytokinin and gibberellic acid, are known to control tuberization. Morphological changes during tuber initiation are accompanied by the accumulation of a characteristic set of proteins, thought to be involved in N-storage (i.e. patatin) or d...

Shwanniomyces occidentalis possess highly efficient alpha amylase activity that enable this yeast to use raw starch as an carbon source. S.occidentalis alpha amylase gene was cloned into the Saccharomyces cerevisiae under the control of different powerful constitutive promoters, ADH1, GPD and TEF. So that the recombinant strains which carries the same gene under the control of different promote...
