Abstract

The use of chitosan as a flocculation in the treatment of liquid waste of leather tanning industry has been studied.Chitosan was used together with commercial polymers PA 322 and PN 161. It was found tahat the addition of 1% solution of chitosan and polymers significantly affected the decrease of turbidity,suspended solid,cod,and chrom content.The use of 1% sulition along with 90 minutes settling gave the best result i.e. lessened the turbidity 98.8%,suspended soild 97.9%,COD 84%,and chorm content 100%.

Abstract

Essential oils are volatile derived from plants, therefore Glc method of analysis is most recommended.Each oil have differentcomponents and quantitatively can be used as a standard if the same procedure is followed.In case from the different sample different"finger print" was found,the sample might be suspected to had been adulterated. The physico chemical constant of the oils are also described in this paper, hence it can be used as a standard for most indonesian commercial oils.

Abstract

Kapol and kapolaga are the local name in indonesia for cardamom.Although their botanical name has already clear for each species,nevertheless there were stil some confusions in regional name.Some people call it kapol for kapolaga on in turn kapolaga was called  kapol. An attempt tom distinguish which is which a GLC analysis on their essential oils were determined.From the result it distinctly can be recognised due to their GLC finger print didi not match each other so their composition were not the same. Kapol oil was totally different from kapolaga oil since its main component was 1,8-cineol,while kapolaga oil contained 1,8-cineol,terpinil acetate and geralsacetate at its main component.According to perseglove (1981)the first was belong to ammomum cardamomum and the latter was belong to Elletaria cardamomum.Since the letter type was more popular and reqodnised in international market,the first type was called as false cardamon. This is no fair since every type of cardamun had their own application and market.The result of this study willbe used as data to support the international standartd organitation (ISO) proposal.

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

The flavours of shallot (Allium cepa linn)and soup leek (A.fistulosum.linn)were separated from their natural sources using solvent extraction technique as wellas juice expression.In the forms of viscous extract liquid and juice concentrate, the flavours were than fixed using the fixation formula US patent 3,619,212; November 9,1971.The stability of aroma and the resistance to microorganisms during storage, and the aroma preference of all fixatives produced were also studied.The result showed that relatively the best stability of aroma was proccessed by the fixatives derived from the extract obtained via the solvent extraction using ethanol 1:1 the resistance to microorganisms of all fixatives was excellent,and the result of sensory eavaluation indicated that the aroma of fixatives derived from the juice concentrate were prefered over thosefrom the ethanol extract.

Abstract

The study imitating "salak" (fruit of salacce edulis) has been done by instrumentation approach.Six components of "salak" flavor,which are probably the key-flavor of "salak" were identified.By compounding the identified components namely ethyl butyrate,isoamyl acetate,alyl caproate,amyl butyrate,linalool and geraniol with another chemical such as aldehyde C19,diphenyl oxide,peru balsam,lemon oil,lime oil,glyserine,ethanol 96%,propylene glycol and cananga oil originated from irian,the artificial "salak" flavor has been created successfully.From the sensory point of view all of panels detected the "salak" flavors of the product,and 6 out of 21 detected another flavor beside the "salak" flavor it self.

Abstract

A research on the effect of process on tannin and phytic acid content of taro corm has been conduced.The study was done on fresh,boiled,steamed and roasted taro corm and also taro flour.The result showed that uncooked taro contained 750.5 mg of tannin and 374 mg of phytic acid per 100 gr.Boiling treatment showed the decrease of tannin of 50.17% and the decrese of phytic acid of 13.57%.The streaming treatment resulted in the decrease of tannin of 49.90%and the decreaseof phytic acid of 16.30%.Roasting treatment showed of tannin of 53.63% and phytic acid 51.11% and flour treatment showed the decrease of 35.31%tannin and 64.37%phytic acid.
