The mechanical and barrier properties of sago starch film incorporated with different percentage of phycocyanin(0.2, 0.4, 0.6, 0.8 and 1.0) were evaluated. With regard to mechanical properties, tensile strength and Youngs modulusdecreased when the percentage of extract Elongation at break (%) increased. and increased with increasing percentage ofextract from 0.2 to 0.1. پرونده مقاله

The condensation of dimedone with sugars in the presence of a catalytic amount of (MWCNTs)-COOH/Fe3O4-CaO magnetic nanostructure gave some asymmetric furan derivatives in good yields. The products were identified by FT-IR, NMR spectra, and elemental analysis. پرونده مقاله

Sago starch polymer is widely used in food, pharmaceutical, textile, etc industries. Their combination with other materials such as sorbitol and glycerin increases their mechanical properties. Mechanical properties are important for edible films. Mechanical tests of the films were performed in accordance to the standard methods. In this regard, the use of various herbal extracts can greatly improve the efficiency of the packaging.In the research biofilm based on the sago starch incorporated with the Abelmoschus esclentus alcoholic extract (2, 4, and 6 grams) and Sorbitol/glycerol was used as a plasticizer and films were prepared under controlled conditions by the casting method using nano zinc oxide and nano zincoxide -Cds5% its properties the mechanical tensile strength (TS) and elongation at break (EAB) and mechanical properties were evaluated with a decrease in the content of the extract. The best results for the concentration of 2gram extract mixed with 0.01gram nanoparticle zinc oxide-Cds5%. Which is the lowest tensile strength and highest elongation at break. پرونده مقاله

Today, the tendency to use biodegradable packaging, including coatings and edible films, is increasing day by day in the industry due to the fact that they are free from synthetic chemicals and do not cause environmental pollution. In this regard, the use of combinations of plant extracts can greatly improve the efficiency of this type of packaging. The purpose of this research is to investigate the effect of alcoholic extracted from flax seed on the mechanical properties of sago starch edible film. In the research biofilm based on sago starch incorporated with the flax seed alcoholic extract (2, 4, and 6) grams , using nano zincoxide and nano zincoxide-Cds5% its property the mechanical Tensile strength(TS) and Elongation at break (EAB) and mechanical properties were evaluated with an increase in the content of the extract. The best results for the concentration of 6gram extract mixed with 0.01gram nanoparticle zinc oxide-Cds5%. Which is the lowest tensile strength and highest elongation at break. پرونده مقاله
