About 90% of dry matter of milled rice is starch and the rest are non-starch components like protein, lipids and ash. Most of the rice based products in Indian sub continent especially in southern part of India are made from rice flour ...
This study was conducted to determine solubility and acid production of some feedstuffs in various fermentation conditions. The solubility was determined at a temperature of 39°C for 24 h and the potential of acid production (PAP) was measured by adding calcium carbonate to filtered fermentation medium. Fermentation of feedstuffs was performed in special gas production syringes both natural and...
should provide new insight into seed dormancy and resistance to preharvest sprouting. Seed dormancy contributes to the adaptability of plants in nature Rice germplasm (Oryza spp.) varies in degree of seed and is of considerable importance in agriculture. The weedy rice dormancy (Roberts, 1961a; Wu, 1978; Oka, 1988, p. 87– (Oryza sativa L.) strains LD, SS18-2, and TKN12-2 and cultivar ‘N22’ 123;...
This paper addresses the potential use of Rice Husk Ash (RHA) as a cementitious material in concrete mixes. RHA is produced from the burning of rice husk which is a byproduct of rice milling. The ash content is about 18-22% by weight of the rice husks. Research has shown that concrete made with RHA as a partial cement substitute to levels of 10% to 20% by weight of cement has superior performan...
Background : Industrial wastewaters contain organic pollutant such as dyes, halogenated hydrocarbon, phenolic compounds and so on Rice husk is a cheap material which is new available in our country. The aim of this study is removal efficiency comparing rice husk ash performance with commercial granulated activated carbon in removal of 2-CP and 4-CP from aqueous solutions. Methods : Experime...
