Characteristics of Edible Film Made from Pectin of Papaya Peel
نویسندگان
چکیده
Papaya (Carica papaya L.) peel contains a considerable amount of pectin, high molecular weight polysaccharides that can be used in edible film making due to its ability form gels. However, from pectin usually has poor moisture barrier properties. Therefore, is generally combined with glycerol as plasticizer and starch. This research aimed utilize the addition corn starch determine characteristics effect concentration on characteristics. Pectin extracted was classified low methoxyl (LMP). The then utilized films together addition. Two factors were this research, which included (0.75 g, 1.0 1.25 g) (40%, 50%, 60%, based pectin). selected formulation an made 1 g 50% (based weight). showed water vapor transmission rate (WVTR) 3.447±0.270 g.mm/m2/hour, moderate tensile strength 1.3121±0.0720 MPa, elongation percentage 9.42±0.08%, thickness 0.11±0.01 mm.Keywords: starch; films; peel;

EXTRACTION AND CHARACTERIZATION OF PECTIN DERIVED FROM PAPAYA (Carica papaya Linn.) PEEL
The aim of study was to extract pectin from papaya peel and study its physico‐chemical characteristics. Pectin was extracted using hydrochloric acid and citric acid, at different time, temperature and pH combinations. Extraction was done at temperatures 60°C, 70°C and 80°C for time 30 mins, 45 mins and 60 mins, and pH 2, 2.5 and 3.0 respectively. Using hydrochloric acid, the yield of pectin was...
متن کاملMicrobial production of pectin from citrus peel.
A new method for the production of pectin from citrus peel was developed. For this purpose, a microorganism which produces a protopectin-solubilizing enzyme was isolated and identified as a variety of Trichosporon penicillatum. The most suitable conditions for the pectin production were determined as follows. Citrus (Citrus unshiu) peel was suspended in water (1:2, wt/vol), the organism was add...
متن کاملOptimization of microwave assisted extraction of pectin from orange peel.
In this study, microwave-assisted extraction was applied for pectin extraction from the dried orange peel and Box-Behnken response surface design was used to study and optimize the effects of processing variables (microwave power, irradiation time, pH and solid-liquid ratio) on the yield of pectin. The amount of pectin extracted increased with increasing microwave power, while it reduces as the...

متن کاملOptimization of Process Conditions for Pectin Extraction from Citrus Peel
Pectin is a complex polysaccharide and natural food additive extracted from citrus peel and apple pomace in the form of brownish powder. It is widely used as a jelling and thickening agent and the food industry especially in jams and jellies. It is also recommended for use as fat replacer and also lowers blood cholesterol by increasing viscosity in the intestinal tract thus lowering cholesterol...
