Abstract

The combination of materials from dangke whey and casein can form an edible flm. The addition of a plasticizer such as glycerol, sorbitol and polyethylene glycol (PEG), in the manufacture of the edible flm can improve the characteristics of the edible flm becoming elastic, fexible and not easily fragile. The purpose of this research was to study the effect of plasticizer glycerol, sorbitol and polyethylene glycol (PEG) to the edible flm characteristics such as thickness, yield, and color (* L, * a and * b). This study was run according to completely randomized design with plasticizer types as the treatment consisted of glycerol, sorbitol, and polyethylene glycol (PEG) with a concentration of 35%. Each treatment was repeated 5 times. The results obtained indicated that the type of plasticizer did not affect the thickness of the edible flm. The yield of edible flm was 26.45 ± 0.34%, 24.53 ± 0.29%, and 22.56 ± 0.30% for glycerol, PEG, and sorbitol, respectively. The color value (*L) of edible flm was 88.40 ± 0.33 for sorbitol, 87.28 ± 0.25 for PEG, and 88.40 ± 0.33 for glycerol. The color value (*a) was 5.97 ± 0.10, 3.86 ± 0.13, and 0.09 ± 0.02, for glycerol, PEG, and sorbitol, respectively. While the color value (*b) of edible flm was 4.36 ± 0.10 for PEG, 1.32 ± 0.36 for sorbitol, and 1.10 ± 0.13 for glycerol. It was concluded that the use of sorbitol would increase brightness (*L) and the yield of edible flm. The use of glycerol has an efect on the reddish color of the edible flm (*a), while the PEG increase the yellowish color of the edible flm (*b).

Abstract

Collagen is one of the protein derivative products that can be produced by hydrolysis process. Collagen proteins found one of them in bone cattle. The protein is strongly bound to minerals in bone. The process of collagen extraction of bone requires a special method. One of them is demineralization process. The combination of several process methods allows collagen to have different properties. This study aims to evaluate the properties of collagen extract produced from broiler bone in the application of a combination of different processes. The study was used a major sample of composite bone from broiler. The main ingredient is using acetic acid (CH3COOH 1M). The applied treatment was a combination of the use of CH3COOH concentration levels (8%, 10% and 12%) with the length of process (24 and 48 hours)[B1] . The data were analyzed by ANOVA using the basic design of Completely Randomized Design (CRD) factorial pattern. Parameters observed included yield, gel strength, viscosity and pH. The results showed that the difference of concentration had significant effect (P<0,05) to pH and viscosity, but no significant effect (P> 0,05) to yield and gel strength. The process length had significant effect (P<0,05) to pH, but to yield, gel strength and viscosity had no significant effect (P>0,05). Application of 10% CH3COOH concentration with a 24 h process length showed better properties in collagen-based composite bone of broiler.  [B1]Variables measured?
