Abstract

Edible film is a biodegradable packaging that can be an alternative as a food packaging material so as to reduce environmental damage and still have the function of maintaining the shelf life, quality and safety of food products. The aim of this research was to determine the effect of using different percentage of whey-chia seed and plasticizer type on the characteristics of films. This research used a completely randomized factorial design consisting of Factor A: percentage of whey-chia seed (A1= 1:0.5; A2= 1:0.75 and A3= 1:1) and Factor B: type of plasticizer (B1= sorbitol; B2= glycerol and B3= PEG). The interaction between of whey-chia seed and different types of plasticizer did not show a significant effect (p>0.05) on the characteristics of films, but the factor of whey-chia seed gave an effect on the thickness and gelation time of the films and the factor of different types of plasticizer too gave a significant effect (p<0.01) on the water vapor transmission rate (WVTR) value. The findings suggest that the incorporation of chia seed concentration with distinct plasticizers could enhance the physical properties of whey-based edible film. The use of percentage of whey-chia seed 1:1 with glycerol is the best treatment.

Abstract

Cellulolytic bacteria are bacteria that produce cellulase enzymes capable of degrading cellulose substrates. This study aimed to isolate and identify as well as measure the cellulase enzyme activity of cellulolytic bacteria isolated from the digestive tract of swans (Cygnus olor) in Mataram. The bacteria were isolated using de Man Rogosa Sharpe (MRS) selective media with the spread plate method. Then, the extracellular enzyme activity test was conducted by growing selected pure isolates on 1% Carboxy Methyl Cellulose (CMC 1%) media, followed by pouring 0.1% congo red solution and rinsing with 1M NaCl solution to determine cellulolytic activity (cellulolytic potential indicated by the appearance of a clear zone around the colony) and measuring the cellulolytic index. The bacterial isolation results obtained 4 isolates with the potential to support fiber degradation in animal feed. The highest cellulolytic index was produced by the isolate coded S1, reaching 34.5 mm, while the lowest cellulolytic index was produced by 2 isolates coded J21 and I2, reaching 18.8 mm.
