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

Unique Composition

The unique composition of camel milk limited its use for fermented products preparation. In this research, camel milk (CAM) or cow milk (COM) was blended with sweet potato starch (SPS). Blends were precooked and the rheological properties of the gel were determined. Since the elastic modulus (G′) was much greater than the viscous modulus (G″), milk + SPS gels are considered viscoelastic. The tan δ of all blends was <1.0, signifying solid-like behavior; however, variations between CAM gels or COM were identified. Unlike COM, CAM was more frequency-dependent at low frequencies (0.1 to 1.0 rad/sec). Gels exhibited shear thinning according to the nonlinear rheological tests. Camel milk exhibited gel hardness much higher than cow milk. Because of the domination of G′ and the low power law exponent, camel milk is expected to present processing complications such as in extrusion cooking.
