Abstract

Glycerolmonolaurate is one of the emulsifiers used in food industries.The addition of such compound into food is to maintain its consistency, improve their texture homogenity and quality.It also stbilizes and thicens food mixture.Further it was understood,that the improvement of food characters depend on the method of emulsifier preparation.An experiment had been carried out to study the effect of heating time  and soda concertration on the Hydrophlyc Liphophylic Balance (HLB) value and its globular size when glycerolmonolaurate was prepared from coconut oil and glycerol.It was foundthat the duration of heating process and soda concertation significantly affected the globular size but did not against the HLB value.

Abstract

Microencapsulation of pepper oleoresin was conducted by using spray dryer in which gelatin, Tween 80, sodium alginat and dextrin were the wall material and pepper oleoresin and lecithin were the core material.The influence of solids concentration and drying condition on the product of microencapsulation and the retention of piperine and volatile oil.Drying temperature,however,may decrease the content of piperine and volatile oil in the product microencapsulated.

Abstract

Jasmine oil was not vapourable by steam destilation due to heat unstability and possibility of hydrolysis.Enfleuration process was recommended when jasmine oil is to be isolated from its flower.Vegetable and animals fat and the mixture of both of them in the form of shortening were studied as jasmine oil absorbent.Varieties of fat and the thickness of chassis effected the yield and the characteristic of jasmine oil were isolatedby this method.It was found that more the thicker the fat layer on chassis the higher oil content can be isolated.Three variables of fat thickness have been studied i.e. 0.5,0.8 and 1.1 cm.From the experiments it was found that the highest yield was obtained on 1.1 cm thicness i.e. 0.29 % from vegetable fat 0.40 % from animal fat and 0.56% from the mixture of animal and the vegetable fat.Based on the rendemen and ester value.The best treatment was animal fat with fat thickness of chassis about 1.1cm produced rendemen about 0.40% and ester value 158.01.

Abstract

A study on the drying of cats whiskers leaf (Orthosiphon staminues benth has been carried out. the treatment of this study were A) fresh leaf weathered, rolled and then dried. the analysis of dried cats whiskers leaf include: yield, color, moinsture, ash, potassium, extract and sinensetin content. the result of dried leaf analysis showed the yield 18.09%, ash 12.09%, extract content 21.43% and senensetin 1.47% at the treatment of D (fresh leaf weathered, rolled and the dried) compared with another treatment and the color is slightly brown. the lowes the moinsture was 8.66% at the treatment of A (fresh leaf were dried directly).

Abstract

Chemical handling of tapioca waste water using coagulans (Alum and poly ammonium chloride), flocculan (polymer code 161),and areation had been done. The treatment in laboratory scale descreased BOD value from 148.59 mg/1 to 54.315 mg/1;COD value from 251.540 mg/1 to 138.875 mg/1; suspended solid from 31.8 mg/1 to 1.719 mg/1; and soluble solid from 2.87 mg/1 to 0.01 mg/1.these result were in accord with the local standard for waste water.

Abstract

The study was aimed at designing and testing of chitosan (polymer) extractor by demineralization, deproteinization, and deacetylation from shrimps shells. the equipment was generated with induction motor of 0.5hp (horse power) and equipped with liquid heater and thermostat in order to maintain temperature level of the process .the blade or propeller agitator was mounted off center.the demineralization process were conducted at 70-75 0C with choloric acid of 1.25 N and 1.5 hours and 2 hours period of process treatment .meanwhile deproteinization were employed at 80-85 0C using sodium hidroxide 3% w/v in the same hours treatment as the demineralization process. sodium hidroxide of 50% (w/v)was employed in the same hours treatment as the demineralization process .which operated at 100-110 0C in the same hours variation of treatment the result showed that thwe best quality chitosan was obtained with demineralization , and deacetylation process which were conducted for 2 hours and 2 run of each process. these were indicated by viscosity resulted e.g 18000 cps (centipoises
