Abstract

This biodegradable packaging is designed to reduce the negative impact on the environment caused by plastic pollution, while still maintaining the shelf life, quality and safety of the packaged food products. The objective of this study was to analyse the moisture content, solubility and optical properties of whey-gelatin multilayer film enriched with green tea powder. This study was conducted experimentally, using a completely randomised design with four treatments and five replicates. The treatments consisted of P1: gelatin/whey-gelatin (G/WG); P2: gelatin/5% green tea powder/whey-gelatin (G/5% GTP/WG); P3: gelatin/10% green tea powder/ whey-gelatin (G/10% GTP/WG) and P4: gelatin/15% green tea powder/whey-gelatin (G/15% GTP/WG). The moisture content and solubility values of whey-gelatin multilayer films showed significant differences (P<0.01). Moisture content was 33.0204-35.3653%; solubility was 40.19-49.96%. The film enriched with 5% green tea powder (P2) produced the best values of moisture content of 34.3536%, solubility of 47.97% and optical (L*= 61.00; a*= -0.36 and b*= 22.58).

Abstract

Edible film is a thin layer that can coat food products and protect them from physical, chemical, and microbiological disturbances. This study aimed to determine the effect of the concentration ratio and different plasticizers on the thickness, water vapour transmission rate, and morphology of protein-based edible films. The study used a completely randomized design with a factorial pattern. The experiment involved two factors: Factor A, which was the whey-gelatine concentration ratio, at three levels (A1 = 1:0.5; A2 = 1:0.75; A3 = 1:1); and Factor B, which was the plasticizer, at two levels (B1 = glycerol; B2 = polyethylene glycol (PEG)). The study revealed that the water vapour transmission rate was significantly affected (P<0.01) by the interaction between whey-gelatin and different types of plasticizers. Additionally, the film thickness was significantly affected (P<0.01) by the whey-gelatine ratio, and the water vapour transmission rate was significantly affected (P<0.01) by the different types of plasticizers used. The film made from protein had a thickness of 0.282-0.357 mm, a water vapour transmission rate of 4.27-5.55 g/mm2.h, and a homogeneous surface structure resulting from the good mixing of whey and gelatin. The concentration of whey-gelatine and the use of different plasticizers can affect the thickness, WVTR, and morphology of the film. The use of glycerol as a plasticizer resulted in a greater thickness, water vapour transmission rate (WVTR), and morphology compared to those of the PEG plasticizer when the whey-gelatin concentration was 1:1.

Abstract

Sembung Village produces chilli that can be used as a source of antioxidant ingredients in functional processed meat products. The activity was carried out through two methods: Demonstration and Participation. The training started with an explanation of processed meat products, including tools and materials, principles of manufacturing methods, packaging, and presentation. The text explains the meaning of antioxidants, how they prevent oxidation, and which natural ingredients contain them. Afterwards, participants were given the opportunity to practice making sausages and meatballs through demonstrations. The majority of attendees were PKK cadres from each hamlet in Sembung Village. The training provides additional information on how to produce meatballs and sausages with added value in the form of healthy, natural antioxidant ingredients. Some participants have experience in meat processing. It can be concluded that the training activity has equipped the Sembung Village community with knowledge and skills that can be utilised to improve their welfare..
