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)

The purpose of this study is to reveal the mechanism of preparing high quality modified starch by ultrasonic technology. In this paper, ultrasonic modified starch and octenyl succinic anhydride modified starch with low degree of substitution were prepared under ultrasonic conditions, using sweet potato starch as raw material. The effects of ultrasound on the structure and properties of native sweet potato starch were studied to see whether ultrasound could produce mechanochemical effect on starch. Then the mechanism of ultrasonic effect on quality of octenyl succinic anhydride modified starch was studied by mechanochemical effect. The results showed that after ultrasonic treatment for 1 min, the crystallinity decreased from 37.6 to 33.8% and reaction efficiency increased from 49.43 to 54.39%, while after ultrasonic treatments for 8 and 32–60 min had different changes. These changes showed that ultrasonic treatment produced significant mechanochemical effect on native sweet potato starch. Ultrasound significantly improved the quality of octenyl succinic anhydride modified starch, and its influence mechanism was revealed using the theory of mechanochemistry. This study provides a feasible method for the research of high quality modified starch and lays a theoretical foundation for expanding the application of ultrasound in various fields.

Starch compound is a hydrocolloid as local resource that needs to be utilized. The addition of glycerol, which funcions as an anti freeze, is hygroscopic and is suitable for environments variety. This research is an experiment desight Randomized Factorial with two factors, each factor consisting of three levels. Data analysis used ANOVA and further test with BNT at the 0,05 % level. The research objective was to determine the ratio of white sweet potato starch to avocado seed starch and glycerol concentration. Thickness 0.02-0.07 mm, tensile strength 0.15-1.37 MPa, and the results of the organoleptic test for aroma and color with the like catagory on hedonic scale. The addition of white sweet potato starch and avocado strarch with glyserol concentration caused the tensile strength to tend to increase and the stability of the edible film increased.

Glucomannan was the main polysaccharide of Aloe vera gel. It was dissolved in water, formed a gel, and transparent as a film. Aloe vera gel was reported antimicrobial and antioxidant activity such as saponin and anthraquinone that was potential for the increased value of an edible film. However, Aloe vera gel form weak film caused glucomannan to have high water absorption. In this research, Aloe vera gel was used as a basis for the polymer film. Yellow sweet potato starch added for the strength matrix component used amylose. This starch expected to give colors from carotenoids. Glycerol also added for the flexibility of an edible film. Randomized Complete Block Design Factorial (RCBD) was applied. The first factor was concentration of yellow sweet potato starch (1%, 2%, 3%) and the second one was glycerol (0,1%, 0,25%, and 0,5%). The parameters tested were color, thickness, transparency, tensile strength, elongation, solubility, water vapor transmission rate, and inhibition zones against E. coli, and S. aureus, fungi A. niger and C. Albicans. The results showed that the addition of yellow sweet potato starch and glycerol with different concentration had a significant effect on color, thickness, transparency, tensile strength, elongation, and solubility. However, an edible film on this research has not to show bacteria and fungi inhibition zone of edible film. P2G1 is the best treatment (yellow sweet potato starch 2% and glycerol 0,1%) produced an edible film with a thickness of 0.12mm, elongation 50.85%, tensile strength 0.55 MPa, solubility 41.03%, transparency 2.13%, vapor transmission rate 3,40 g/m2/24hours, L, a+, b+ score in sequence 41.87, 0.2, and 4.1.

<p>Edible film is one of alternative packaging which can consume and still protect product from losing nutrition, appearance, flavor, dehydrate and deteriorate at storage and isn’t damage environment. More research using local starch from sweet potato (Ipomea batatas L. poir) was studied. But, characteristic from sweet potato starch shows poor in quality. So, mixing starch with chitosan studied to make characteristic of edible film more useable for wide area. This research to know how is characteristic of edible film starchchitosan. One edible film use 0,8 mL glycerol or 20% (v/w) and chitosan’s soluble 1% acetate acid. One factor uses in this research is amount of chitosan with 3 level 0,5 gram; 1,0 gram; and 1,5 gram. Then, edible film analyzed physical (thickness, solubility and permeability) and mechanic (tensile strength and elongation). Result of research show more chitosan add significantly increased thickness and tensile strength of edible film and significantly decrease solubility and elongation of edible film. But, edible film show no significantly decrease of permeability. Adding more chitosan in edible film starch-glycerol increase edible film thickness to 0,13 –1,90 mm and decrease solubility to 66,87–58,20%. Tensile strength show increase to 1,27–6,90 MPa and elongation decrease to 79,71–46,98%. And for permeability of edible film decrease to 12,40–9,97 (g/ hour m2).</p>
