Abstract

 A study on the effect of oleoresin on rice quality during storage has been coducted. Four treatment were done i.e. spraying using pepper oleoresin of 200, 250, 300 ppm and control. Each treatment used 5 kgs rice packed in gunny sacks. Spraying were done on the sacks. Observation on the amounth of rice weevil, texture, taste, flavor and colour, was done every two months. The result showed that up to four months storage, the amounth of weevil in rice sprayed with 250 ppm oleoresin decreased by 70.74% as compared to control, and have the most preffered texture and colour, more preffered flavor as compared to control and no significantly different taste as compared to other treatments. Up to six months storage, the same treatment decreased the amounth of weevil by 49.76%, while those with higher concentration (300 ppm) decreased the weevil by 66.08% but the texture, taste and colour were not significantly different as compared to other treatments.

Abstract

This study was designed to analyze the effects of chitosa-formic addtition to retanning of leather and printing proces of textile .the type of leather used was boks leather and those for textile consist of polyester,polyacrylic,contton, and nylon. chitosan was extracted from shrimps and crab shells which produced from shrimp shells, crab shells,and mixture from those shell was then mixed with formic acid(3%) to produce chitosan-formic with the concentration of 7.5% for each treatment.in retaning leather ,chitosan-formic was used as filling agents meanwhile in printing textiles these was applied for the low quality leather and itsesults was compared with the leather without chitosan-formic addition in textiles printing chitosan-formic was printed with any kids dyestuff and materials such condition was applicable only when it usedas singles dyestuff meanwhile when it as applied with other auxiliaries chotosan-formic was not complatibe for the rest of destuff and textilles material.
