Properties of Edible Film Produced using Combination of Collagen Extracts of Bligon Goatskin with Glycerol

Abstract

Edible films are one of packaging products that environmental friendly. Edible films can produce from the by-products of the slaughtering of livestock locally. Edible films used as materials packaging of foodstuff to protect food products of contamination of air, light, lipid, dissolved substances and microorganisms. One of the main advantages of edible film packaging is a natural character, so it can consume together with such food products. The purpose of this study was to evaluate the properties of edible film that produced from a combination of collagen extracts from glycerol as a plasticizer. The study was using collagen extract produced from materials of goatskin, Bligon types and ages 2-2.5 years as the main material and glycerol as ingredients plasticizer. Methods of this study were using experiment design with completely randomized pattern unidirectional the design. Three concentrations of glycerol applied, namely: 80%; 90% and 100% (of the total extract collagen in the mix) combined with 10% (w/v) extract collagen. The results showed that the difference concentration of glycerol that used in the mix effect in the thickness, tensile strength and elongation, but no significant on the solubility, water vapor transmission rate (WVTR) as well as a w values of edible films. The study implication was the application F 1 formula (10 g (10%) of extract collagen solid + 8 g of glycerol (80%) + 100 mL of distilled water) generating properties of edible films better.

Gelatin- and Papaya-Based Biodegradable and Edible Packaging Films to Counter Plastic Waste Generation

“…The use of plasticizers increases the physical and functional properties of edible films, (1) flexibility, sensitivity, and moisture, and changes (2) functional properties. Plasticizer decrease influences: (1) the biopolymer chains adjacent to each other, (2) the sensitivity that occurs out of the water, and (3) the flexibility of the material [ 58 ].…”

Characteristics of Feather Protein Concentrates Hydrolyzed Using Bacillus subtilis FNCC 0059

“…The addition of fluoride added with hydrogen peroxide (5% w/w) increased the degradability of the in situ protein, however, did not alter the dry matter intake, average weight, feed efficiency and improved characteristic of the carcass cattle (Loest et al, 2002). The value of the protein content of FPC is not different from protein content of feather meal derived from the skin of Bali cattle (85.20-87.67%) (Said et al, 2016a) and research result by Gang et al (2013) …”

Organic-inorganic biohybrid films from wool-keratin/jellyfish-collagen/silica/boron via sol-gel reactions for soft tissue engineering applications

“…Its role is to enhance film flexibility by mitigating intramolecular and intermolecular attraction forces, thereby facilitating the mobility of polymeric chains [41]. However, some studies on the effect of adding glycerol on the mechanical properties of keratin and collagen-based films have reported that as the number of glycerol increases, the tensile strength decreases while the elongation at a break increase [42,43]. In the work presented here, Si-B-WK/JFC film exhibited lower mechanical properties than Si-B-WK film.…”
