Abstract

Processed meat products that are common and much preferred by the consumers are sausages and beef meatballs. This processed product has the disadvantage that it has a high-fat content, causing faster oxidative damage. This study aims to observe differences in the nutritional value and antioxidant activity of meatballs and sausages from Bali-beef and Lamtoro-beef. The main research material is fresh Bali-beef and lamtoro beef using several chemicals and laboratory equipment related to proximate analysis and antioxidant testing. The study was designed based on a Completely Randomized Design with 4 treatments and 3 replications and continued with Duncan's test SPSS version 16 programme. The results showed that the highest crude protein content was found in lamtoro-beef with lower fat content, water content, and ash content compared to fresh Bali-beef. Meatball and sausage products with the raw material of lamtoro-beef were not significantly (P>0.05) had a higher crude protein content than meatballs and sausages with the raw material of Balin-beef. The antioxidant activity of fresh Bali-beef and its processed products (meatballs and sausages) was not significantly (P>0.05) higher than the antioxidant activity of lamtoro-beef. Conclusion: Lamtoro-beef and its processed products in the form of meatballs and sausages have a higher protein content with lower fat content, water content and ash content compared to fresh Bali-beef. Meatball and sausage products made from fresh beef were not significantly (P>0.05) had higher antioxidant activity than lamtoro-beef.

Abstract

Edible film is an alternative packaging that can be applied to food because it has biodegradable properties. The use of plasticizers can be used in the manufacture of edible films to increase the flexibility and densibility of the film. This study aims to determine the effect of plasticizer type on the thickness, WVTR, and moisture content of whey-gelatin film blends. The research was conducted in a Completely Randomized Design with three treatments, treatments that make a difference are tested with Duncan's Multiple Range Test (DMRT). The treatment used different plasticizer (P1G: Glycerol; P1S: Sorbitol; and P1P: polyethylene glycol (PEG) 400). The properties of whey-gelatin films showed that thickness was at 0.0350-0.0352 mm; the WVTR was at 4.87-6.22 g/m2/day; the water content was at 12.55-15.69%. The use of glycerol as plasticizer produced the best edible film characteristics compared to sorbitol and PEG 400 with a thickness value of 0.0350 mm; WVTR of 6.22 g/mm2/day and moisture content of 12.55%.

Abstract

Edible film is a type of biodegradable packaging that can be an alternative to food packaging material to reduce environmental damage and maintain food product’s shelf life, quality, and safety. This research aims to determine the effect of the mechanical properties of protein-based edible film using different concentrations of sorbitol plasticizer on edible film thickness, gelation time, and film microstructure. To make edible films, the research material consists of sorbitol, whey protein, gelatin, distilled water, and silica gel. The research was conducted using a completely randomized design with three sorbitol plasticizer treatments consisting of P1:35%, P2:40%, P3:45%, and three replications. The data were analyzed using Analysis of Variance (ANOVA) and continued with the Duncan Multiple Range Test (DMRT) using the SPSS program. The research results showed that the use of sorbitol plasticizer with different concentrations gave a very significant difference (P<0.01) to P1 and P3, but P2 was not significantly different from the thickness of the edible film. The gelation time did not make a difference (P>0, 05), which is real, but adding different sorbitol to the edible film microstructure can produce varying microstructures. From the research results, the average values for edible film thickness are 0.053, 0.078, and 0.113 mm, while the gelation time produces average values of 19.33, 13.33, and 19 minutes. This research concludes that using different sorbitol concentrations provides a very significant difference in film thickness; however, unlike the gelation time, which does not make a difference, the microstructures produce varying microstructures.
