Starch Production

In order to improve sweet potato starch production technique of small-scale plant and decrease the discharge of pollutant in production wastewater, the yielding water of starch production was treated efficiently by the new environment materials and technology. Subsequently, the treated wastewater was circulated and reused in starch producing process. The results showed that the quantity of starch wastewater was decreased. When the recycle ratio is below 30%, the starch quality was hardly influenced. When the recycle ratio is above 50%, the pollutants in wastewater increased significantly, starch yield dropped nearly to 50% and starch acidity exceeded the national standard. Finally, wastewater reuse ratio should be controlled below 30%.

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
