Abstract

It is not known how to extract carotenoid- which has a high value -optimally from palm oil  mesocarp fiber (POMF). The research objective was to determine the optimization of oil extraction from POMF waste and to determine the optimization of carotenoid extraction from POMF oil. The research was carried out in 2 stages: The first stage was oil extraction from the POMF with the treatment factor ratio of hexane to the weight of the POMF and the extraction time. Stage 2 Optimization of carotenoid  extraction using the solvolitic method with treatment: Minor solvent types Methyl ester (Me) caprylate-caprate (C8 –C10) and Me laurate-myristate (C12-C14) and minor solvent concentrations of 0.1% and 0, 25%. Parameters analyzed were: oil content, Deterioration bleaching of index (DOBI), and carotenoid concentration. Optimization ratio between hexane and POMF weight is 1:40 (vol / g) with an oil content of 2.938%. Optimization of extraction time for 100 minutes with 4.104% oil content. Optimization of carotenoid extraction is by using minor solvent Me C8-C10 with a solvent amount of 0.1% which results in a carotenoid concentration of 302.442 ppm and DOBI of 5.74. The increase in caroten concentration resulted from saponification reached 114.2 times from the carotenoid concentration in POMF oil.

Abstract

The attractive colors and colors derived from natural pigments are very much favored by consumers, as natural pigments in addition to being dyes also serve as a source of vitamins. The aims of this  study were to determine the effect of the amount of nanoemulsion applied  and storage duration on the color of wet banana noodles and the potential of wet noodles as a source of carotenoids and to increase the level of consumer acceptance of the color of wet noodles. The research used complete Random Design (RAL) factorial where first factor was the amount of nanoemulsion consisted of 3 levels namely: 0%, 3% and 6%. Second factor was storage duration consists of 3 levels :0 days, 3 days, and 6 days. Each treatment with three replications. The results showed that the color of wet noodles ranged from yellowish to yellow. The intensity of the yellow color decreased during the storage process. The 3% nanoemulsion applied on wet noodles potentially suffice 4.4% of the vitamin A requirement  and its potency decreased to 2.6% after the noodles were stored for 6 days. While noodles applied 9% nanoemulsion on noodle was potentialto suffici vitamin A by 10,4% from requirement of vitamin A, but decrease to 4.3% after wet noodles were kept for 6 days. The storage duration gave no significant effect on the color preference test but the nanoemulsion application increased thelevel of panelist's preference on wet noodles color from  2.2 (dislikes) to 4.05 (like).Key words: wet banana noodle, nanoemultion, colour,  vitamin A
