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

A research on the effect of varieties and methods of extraction to the yield and content of catechin of gambier has been conducted. Leaves of gambier from Uncaria gambir Roxb and Uncaria payakumbuh were extracted by steaming and boiling for 5-10 minutes, then pressed in 18.000 kg/cm^2 pressure and dried for 3-4 days. The yields of gambier were 6,44-6,47% (steaming) and 4,80-5,00% (boiling) respectively, whereas the catechin content of gambier were 64,45-65,08% (steaming) and 53,24-55,47% (boiling). Methods of extraction by steaming has a higher yield and catechin content than extraction by boiling.

Abstract

This report deals with a study on the effect of bleaching earth type used and methods of adding the bleaching earth on the isolation of beta-carotene content from crude palm oil (CPO) using absorption method.The type of bleaching earth used were Master Brand,Champion and Bentonit alam Indonesia,while the bleaching earth concentration used was 15% which given in three methods i.e.first it was given at once addition only, second at twice addition and third at three times addition.It was shown that the combination treatment between Bentonit Alam Indonesia bleaching earth,gave the best result with 55,08% beta-carotene content,11.00% loss quantity of crude palm oil and 55 ppm beta caronete content of crude palm oil after bleaching process.

Abstract

This report deals with studies both on the extraction of cumin oil from cumin seed (Curcumin cyminum L) using cohobation method and the effects of Sodium chloride (NaCL) or Barium Cuminum chloride (BaCl2) on the quantity and quality of cumin oil. It showed that the addition of Sodium chloride or Barium chloride at the 5,10,15 and 20 percent of concentration, increased the yield from 2.23 to 2.65 percent, specific grafity from 0.9281 to 0.9427 and the acid number from 3.14 to 6.44; but decreased the ester number from 27.80 to 19.00. Generally, however, the analysis result by means of Gas Chromatography showed that the purity and chemical component of cumin oil in each treatment given was not different
