The use of plastics is resisted worldwide. Therefore, finding alternatives to plastic packaging products is an urgent issue. This work was dedicated to the preparation of biodegradable composited films with potato starch, glycerol, and gelatin. The formulation of the biodegradable film was first optimized via response surface methodology combined with the multi-index comprehensive evaluation method that considered physical properties (thickness, water solution (WS), tensile strength (TS) and elongation at break (E%)) and barrier property (light transmittance (T%)). Results indicated that the o

Abstract In this study we have prepared flexible gelatin/sericin/clay blend films for packaging applications of hygiene products. Gelatin/sericin (3:1, 1:1 and 1:3 w/w ratios) films were prepared using glutaraldehyde as a crosslinking agent and glycerol as a plasticizer by the solution casting method. The concentrations of gelatin and sericin were optimized on the basis of their mechanical properties. Closite 30B and copper-modified montmorillonite clay (with concentration of 1–5%) were incorporated into the optimized gelatin/sericin blend films in order to improve the mechanical and antimicro

The effect of glycerol content on the physical properties of gelatin-based edible films was studied in this work, on the basis of the interactions between the plasticizer and polymeric matrix. In this work, some non-usual techniques were used to characterize edible films. For dielectric measurements and infrared spectroscopy, these films were conditioned in silica gel in order to minimize the water effect. For other analysis, the films were conditioned in NaBr. Infrared spectroscopy showed no apparent changes in the position peaks, suggesting an absence of new interactions between the plastici

The raw material used for this NCC production was oil palm empty bunches (OPEFB), currently waste from oil palm plantations. Delignification of OPEFB was carried out using 2 N NaOH solution at 70oC for 6 hours. NCC maximum yield from OPEFB is 62.1% (dry cellulose basis) obtained at a concentration of 54% sulfuric acid and a temperature of 50oC. The addition of plasticizers (glycerol and PEG) reduced the elastic modulus of NCC capsules from 7951.4 MPa to 4758 MPa (glycerol) and 3225 (PEG). The addition of glycerol and PEG did not affect the disintegration time of NCC capsules. NCC capsules have

A newly isolated alkaline protease-producing myxobacterium was isolated from soil. The strain was identified as Pyxidicoccus sp. S252 on the basis of 16S rRNA sequence analysis. The extracellular alkaline proteases produced by isolate S252 (PyCP) was optimally active in the pH range of 11.0–12.0 and temperature range of 40–50°C The zymogram of PyCP showed six caseinolytic protease bands. The proteases were stable in the pH range of 8.0–10.0 and temperature range of 40–50°C. The activity of PyCP was enhanced in the presence of Na+, Mg2+, Cu2+, Tween-20, and hydrogen peroxide (H2O2) (hydrogen pe

Nowadays, consumers demand high quality food products with an extended shelf-life without chemical additives. Edible coatings (EC) containing natural compounds are a promising preservation technology for raw seafood without compromising fresh-like appeal and nutritional content.The aim of this work was to evaluate the effect of Thunnus obesus skin gelatin-based EC containing Codium spp. or Fucus vesiculosus extracts on raw tuna preservation. Three gelatin-based EC (gelatin (5 %) + glycerol (25 %); gelatin (5 %) + Codium spp. (1 %) + glycerol (25 %); gelatin (5 %) + Fucus vesiculosus (1 %) + gl

The increase in population causes the level of basic needs to increase, one of which is in terms of food. Where mostly, the food industry uses petroleum-based plastic packaging, the use of these materials can contaminate food due to the nature of the chemical substances that are easily mixed with the packaged products. Therefore, it is necessary to have packaging technology that is safe and does not damage the environment, for example edible film (McHugh and Krochta 1994). The process of making edible films is carried out by mixing the independent variables, namely the concentration of CaCO3,

Purpose This study aims to investigate the application of red cabbage extract in biodegradable composite-based edible film and evaluate its physicochemical characteristics and ability to be used in steamed chicken packaging. Design/methodology/approach Cassava starch, gelatin and glycerol were used as basic materials for edible film. Red cabbage extract was infused, and eggshell powder was also incorporated. The smart edible film formulation consists of six treatments which are C (control: cassava starch + gelatin + glycerol), CE (control + 0.1% eggshell powder), CRA (control + red cabbage A r

Objective: The aim of the present study was to design and evaluation of mouth dissolving oral films of tofacitinib citrate allowing fast reproducible drug dissolution in oral cavity thus bypassing the first-pass metabolism to enhance the patient convenience and effective treatment for rheumatoid arthritis. Methods: Films have been prepared by way of solvent casting technique by using Hydroxypropyl methylcellulose (HPMC), sodium carboxymethylcellulose, sodium alginate, and gelatin had been used as the hydrophilic film-forming polymeric bases and glycerol as plasticizer. The prepared film evalua
