Cereal Chem. 79(3):383–386 The objective of this study was to compare the structure and properties of flours and starches from whole, broken, and yellowed rice kernels that were broken or discolored in the laboratory. Physicochemical properties including pasting, gelling, thermal properties, and X-ray diffraction patterns were determined. Structure was elucidated using high-performance sizeexcl...

This work investigated the production of the fungi Isaria fumosorosea and Isaria farinosa in biphasic fermentation using agro-industrial products and residues. Combinations of natural liquid substrates, alternative to the complete medium and potato dextrose medium, were evaluated. The best liquid media were sugarcane molasses + rice broth, rice broth + yeast and sugarcane molasses + yeast + ric...

rice is usually harvested at a high moisture content therefore it must be subjected to drying till the moisture below 14% and for longer storing till 12%. in this project a fixed laboratory dryer was selected for drying three varieties with three range of temperature 40, 50 and 60 c and two range of final moisture content 12% and 10% as completely randomized design. correlation of crack kernel ...

A Fourier descriptor is one of the best methods for describing object boundaries, but there are limitations in describing the boundary of rice kernels using traditional Fourier descriptors. An innovative approach was developed to describe rice kernel boundaries by improving a traditional Fourier descriptor. This radius Fourier descriptor (RFD) uses a radius set for rice kernel images as its bas...

During the rice milling process, a huller system is used to remove rough rice hull, then abrasive or frictional mill product whitened rice. In such machines adjustment and control, operation is important, because breakage percentage of rice is one main factor in determination of quality. Today’s image processing techniques has become an increasingly popular and cost-effect...

A study was carried out at the Rice Research Institute of Iran (RRII) to investigate the effect of rollers differential peripheral speed of commercial rubber roll husker and paddy moisture content on the husking index and percentage of broken rice. The experiment was conducted at six levels of rollers differential speed (1.5, 2.2, 2.9, 3.6, 4.3 and 5 m/s) and three levels of paddy moisture cont...

The objective of this experiment was to test the hypothesis that the apparent total tract digestibility (ATTD) of DM, OM, fiber, and GE by weanling pigs and the concentration of DE and ME in full-fat rice bran (FFRB), defatted rice bran (DFRB), brown rice, and broken rice is improved if microbial xylanase is added to the diet. Eighty pigs (13.6 ± 0.8 kg initial BW) were allotted to 10 diets wit...

Fissuring caused by rapid moisture adsorption generates appreciable amounts of broken kernels on subsequent milling, thereby reducing the economic value of rice. This study investigated how rapid moisture adsorption affects the extent of kernel fissuring in rice lots, as well as the physical and functional characteristics of broken kernels that result from milling such lots. Pure-line, long-gra...

multistage and semi-mechanized harvesting of rice in khouzestan province, iran, causes much loss. depending on available facilities and conditions, either spike-tooth or rasp-bar cylinders are employed with either direct or indirect combine harvesting methods. the present research studied the effect of these different harvesting methods on the amount of losses in two rice varieties in 2001-2002...

The component of protein in rice, at 7-9% by weight, is relatively low, but the total amount of rice protein potentially available is significant because the production of rice worldwide, at 380 million tons annually, is huge. Rice proteins are recognized as nutritional, hypoallergenic, and healthy for human consumption, and rice protein products have been in demand in recent years. However, be...
