Physicochemical Properties of Niigata Waxy Rices

Physicochemical properties and digestibility of hydrothermally treated waxy rice starch.

Waxy rice starch was subjected to annealing (ANN) and heat-moisture treatment (HMT). These starches were also treated by a combination of ANN and HMT. The impact of single and dual modifications (ANN-HMT and HMT-ANN) on the molecular weight (M(w)), crystalline structure, thermal properties, and the digestibility were investigated. The relative crystallinity and short-range order on the granule ...

Physicochemical Properties and End-use Quality of Wheat Starch as a Function of Waxy Protein Alleles

Soft wheat (Triticum aestivum L.) quality tests (milling and baking quality) and starch characteristics (amylose concentration, X-ray diffractograms, thermal properties and pasting properties) were determined for eight granule-bound starch synthase (GBSS: waxy protein) genotypes in a soft wheat background. Lines carrying two null alleles showed reduced amylose concentrations relative to those o...

Physicochemical properties of bacterial surfaces.

Streptococcal M protein is one of the best characterized anti-phagocytic surface molecules. The protein has a coiled fibrillar structure extending outwards about 600 nm from the streptococcal cell wall. The anti-phagocytic nature of the M protein appears to be related to two properties: ( a ) its ability to bind fibrinogen and the D family of its degradation products, thereby preventing deposit...

Physicochemical properties of human lactalbumin.

Proteins of the same kind in human milk and cow's milk have different properties. Mellander (1947) reports differences in phosphorus content and the amount of carbohydrates of casein and that the casein of cow's milk is more easily digested by proteolytic enzymes in vitro than that of human milk. Kiyosawa, Ryoki & Maeno (1961) observed a marked difference in the solubility of casein and the tur...
