Thermal Processing Effects On Rice Characteristics, Shuh-Ming Chang, Hsiu-Chen Yang

Food Structure

Whole kernels of four cultivars of milled rice were treated under different conditions according to our traditional methods such as boiling, steaming, autoclaving or roasting with sand. During the vari ous processing conditions, the moisture contents of the kernel , heating temperatures, pressures and heating times were varied. In this paper, the physicochemical properties of those processed samples were investigated and compared.

Based on degree of gelatinization , water absorption index , water solubility index , swelling power, viscoamylograms and X-ray diffraction patterns, the propenies of waxy rice samples arc different from that of non -waxy rice samples. They are …

Influence Of Addition Of Polyols And Food Emulsifiers On The Retrogradation Rate Of Starch, M. Muira, A. Nishimura, K. Katsuta

Food Structure

The influence of polyols and emulsifiers on hardening of non-glutinous rice starch gels has been investigated. The polyols and emulsifiers were added at concentrations of 6% (w/w) and 0.2% (w/w), respectively , to starch gels (starch content, 30%). The hardening rate and the initial viscoelastic values of gels were computed by analyzing static linear viscoelastic parameters (creep compliance) of the gels stored at 0 C for up to 3,000 minutes.

Hardening of gels, i.e., retrogradation of starch, could be described by a first order kinetic equation. Polyols prevented the retrogradation of starch, and formed rigid and stable gel matrices. Emulsifiers …

Practical Methods For Identification Of Rice Endosperm Protein Bodies And Fecal Protein Particles In Light Microscopy, D. L. Barber, J. N. A. Lott, D. A. Harris

Food Structure

Indigestible 1-3 ~m protein 'cores', particles that originate from protein bodies of rice endosperm, were examined in bright-field and fluorescence microscopy, using a variety of histological and histochemical procedures. Our application of histological, histochemical and chemical approaches to a study of the feces of aoimals fed rice-containing diets has resulted in the development of methods for routine identification of insoluble rice fecal protein particles. For the specific identification of rice endosperm storage protein, whether protein bodies, cores or fecal protein particles, aqueous eosin Y stain in conjunction with fluorescence microscopy, and a combination of orange G + aniline blue in …

Biochemical Investigations Of Black Gram (Phaseolus Mungo L.) And Rice (Oryza Sativa L.) Proteins And Their Improved Nutritional Functionality In The Fermented Product—Idli, Vinodkumar W. Padhye

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The objectives of this investigation have been to characterize black gram (Phaseolus mungo L.) and rice (Oryza sativa L.) proteins and to study changes in their nutritional value due to fermentation. Black gram, the legume chosen for this work, is one of the most important legume crops throughout a large part of the tropics.

The protein content of 60 mesh, dehydrated, defatted black gram meal was 28.5 percent. Sodium carbonate (0.5-1.0 percent), tetra-sodium pyrophosphate (0.5 percent), and sodium dodecyl sulfate (SDS) (0.5-5 percent) proved to be the potential protein solubilizers as they extracted more than 76 grams of …
