  Potentially lactic acid bacteria as a starter for EPS production from yellow sweet potato fermentation were determined. The fermentation profile and partial characteristics of isolated lactic acid bacteria were used as considerations. The fermentation of yellow sweet potato was performed in the back-slopping and spontaneous procedure and was paid attention to the hours of 0, 24, 48, and 72.  The results showed that the 72 hours of fermentation was found to have the highest EPS metabolites, the number of a LAB, the total lactic acid, and the lowest pH. The 72 hours of fermentation also seemed to cause a significant change in the sweet potato starch granules morphology.   The potential starter, therefore, can be taken from the yellow sweet potato fermentation either spontaneously or by a back-slopping method, at 72 hours. From the sixty selected LAB, the 34 strains showed an ability to produce EPS. Among these, eight strains exhibited the potential high production of  EPS.  They were capable of growth on 28-45C and exhibited tolerance to 3-4% NaCl. The favorable carbon sources for the growth and production of EPS were isolated dependent.

White sweet potato starch (Ipomea batatas L.) and avocado seed starch (Parsea americana Mill) derived from local plants have the potential to be developed as agricultural products. Starch is a hydrocolloid compound as a potential local resource to be utilized. Glycerol function as an anti-freezing which is hygroscopic. This study aims to determine the ratio of white sweet potato starch with avocado seed starch and the concentration of glycerol for making edible film. This study was an experiment using a completely randimized factorial design with 2 (two) main factor consisting of a comparison of white sweet potato starch and avocado seed with 3 levels: P1 = 35%:65%., P2=50%:50%., P3=65%:35% and glycerol concentration with 3 levels: G1=1%., G2=2%., G3=3%. The best result reasearch were content of 23.03% (tratment P1G1), solubility of 55.57% (treatment P3G2)., swelling test of 9.83% (treatment P2g3)., elongation of 8.18% (treatment P3G2)

Zinc Fortification

ZINC FORTIFICATION OF ARTIFICIAL RICE FROM PURPLE SWEET POTATO FLOUR AND STARCH. Zinc deficiency is believed to be as common as that of iron, with equally negatives consequences. Fortification of artificial rice with zinc is a cost-effective method that can be used to solve this problem. In the present study, artificial rice made from purple sweet potatoes flour and starchwere evaluated as food vehicles for fortification with zinc. This study consists of four main stages, preparation of flour and starch of purple sweet potatoes, zinc fortification, and artificial rice production. Zinc sulphate and zin acetate were used as the fortificant, and added at a level 50, 75, 100, and 125 ppm. Artificial rice fortified with zinc has been successfully carried out. Zinc concentrations in fortified artificial rice are higher than unfortified rice. Artificial rice has a porous structure, in order to improve the rehydration capacity.      Keywords : Artificial rice, Zinc (Zn) fortification , Purple weet potato flour, Purple sweet potato starch,  Defisiensi seng dipercaya telah meluas dan memiliki pengaruh negatif yang sama dengan defisiensi besi. Fortifikasi seng pada beras analog dipercaya dapat mengatasi permasalahan tersebut. Berdasarkan penelitian dengan variasi penambahan konsentrasi Zn pada beras analog ubi ungu. Penelitian ini menggunakan beras analog yang terbuat dari tepung dan pati ubi ungu sebagai food vehicle. Penelitian ini terdiri dari 4 tahapan utama, pembuatan tepung dan pati ubi ungu, tahap fortifikasi seng, dan proses pembuatan beras analog. Seng sulfat dan seng asetat ditambahkan pada konsentrasi 50, 75, 100, dan 125 ppm. Beras analog terfortifikasi seng memiliki konsentrasi seng yang lebih tinggi bila dibandingkan dengan beras analog tanpa fortifikan. Beras analog terfortifikasi seng juga memiliki struktur berpori sehingg dapat meningkatkan kemampuan rehidrasi.   Kata Kunci : Beras analog, Fortifikasi Seng (Zn), Pati ubi ungu, Tepung ubi ungu
