Objective: To obtain biofilms from starch and cellulose present in the avocado (Persea americana) peel seed. Materials methods: The characterization included humidity, gelatinization temperature, paste clarity, absorption index, solubility swelling power, amylose, amylopectin, amount, yield. Five mixtures were made with 3 g of starch, 5 mL 30 % NaOH (w/v), cellulose, different proportions for g...

Cold plasma is an innovative strategy to strengthen the polysaccharide-based films characteristics. This study evaluated effects of dielectric barrier discharge (DBD) on hydrophilic character, water vapor permeability (WVP), and tensile properties corn starch-based films. Starch were exposed processing operating at excitation frequency 200 Hz for 10, 15, 20 min. DBD resulted in further enhanced...

Grape processing residues are a good source of bioactive and nutritional compounds. The incorporation grape pomace extract (GPE) in starch films can be strategy for the elaboration new food packaging products applications such as edible or fruit strips. In this context, objective research was to analyze effect variation concentration GPE (0, 20, 30, 40% mass/mass solids) on physical chemical pr...

Despite the presence of a rutinosyl group at 3-OH, aqueous solubility flavonoid rutin is even lower than that its aglycon quercetin. In this work, we describe fast, simple, and easily scalable process for polyglucosylation to enhance solubility, catalyzed by cyclodextrin glucanotransferase (CGTase). Several reaction parameters (source enzyme, rutin/starch weight ratio, cosolvent, pH, temperatur...

This study aimed to estimate the effects of extrusion variables on extruded aquafeed water solubility using a starch gelatinization model. A new equation was derived from classical degree model calculate solubility. After considering data five formulations, average absolute deviation (AAD) 7.97% for extrudate and 2.24% index. In most cases, index increased with an increase in process screw spee...

Indomethacin (IM), most widely used non-steroidal anti-inflammatory drug widely used in developing countries, is classified in Class II in the Biopharmaceutics Classification Systems; this means that IM has very low water solubility and high permeability, thus the dissolution is the absorption rate-limiting factor. The aim of this work was to evaluate the suitability of melt granulation techniq...

In this study, hydric and biodegradability properties of cassava starch-based bioplastics reinforced with crude kaolin or treated kaolinitic clay at 700 °C called metakaolin were investigated using water adsorption microbiological tests. Non-reinforced (BP) those containing 5 wt.% (BPKB) (BPMKB) manufactured the casting/evaporation method. Results obtained showed a decrease in solubility diffus...

Chickpea starch was modified by heat-moisture treatment (HMT). The effect of on the amylose content chickpea studied, and physicochemical properties, gelatinization texture properties digestion were compared analyzed scanning electron microscopy (SEM), X-ray diffraction (XRD) Fourier transform infrared (FT-IR). After HMT, increased. Compared with natural starch, morphology granule changed destr...
