Abstract

Edible film is a thin layer as a coating for foodstuffs made from edible materials such as taro. One of the taro tubers variety that can be used as edible film is Beneng from Banten. Edible films made from starch have a weakness that is easy to tear and have low elasticity, to change the physical properties of the film from starch it is necessary to add a plasticizer. Plasticizers that are often added to the production of edible films are xylitol, sorbitol, polyethylene glycol, and glycerol. The purpose of this study was to determine the effect of the type of treatment and concentration of plasticizer on the physical-mechanical properties of edible film made from taro beneng starch. The treatment in this study was divided into 2 factors, the first factor was the type of plasticizer (sorbitol, glycerol and PEG), while the second factor was the concentration of the plasticizer (1%, 3%, and 5%). The tests carried out in this study were the tensile strength, elongation, thickness, water vapor transmission, and water solubility tests. The results showed that the type and concentration of plasticizer have a significant effect on the characteristics of the edible film. The interaction between the type and concentration of plasticizer has no significant effect on the water vapor transmission test. The best edible film in this study was the edible film with the addition of the plasticizer sorbitol with a concentration of 3%.

Abstract

Beneng taro, a local food plant in Banten Province, has enormous potential to be developed as an effort to diversify food, one of which is used as a raw material in the manufacture of food bars. Ingredients formulation and roasting temperature can affect the characteristics of the resulting food bar. Therefore, researchers consider it necessary to conduct research related to the physical and sensory characteristics of food bars based on beneng taro, mocaf and soy protein isolate as one of food diversification, as well as the best formulation and roasting temperature of the food bar. This study used a completely randomized split plot design with two factors, namely roasting temperature and ingredients formulation. The L* value, a* value, and texture were all significantly impacted by the roasting temperature, according to the results. Meanwhile, the L*, a*, and b* values were significantly impacted by the addition of beneng taro flour and soy protein isolate. The a* value, b* value, as well as the panelists' evaluation of the color, texture, and overall parameters are significantly impacted by the interaction between the two factors. The formulas for the chosen food bars contained 30% taro flour and 70% soy protein isolate, and they were baked at 140 °C (S2R2) with the following characteristics: texture 26,59 N; L* value 46,75; a* 14,99; b* 32,17; and the value of preference for color, taste, aroma, texture and overall is 2,23; 2,10; 2,23; 2,15; and 2,25.
