Abstract: Bionanocomposites films of cassava starch plasticized with sucrose and inverted sugar reinforced by cellulose nanocrystals (CNCs) were prepared solution casting method incorporating 0.1 to 5 wt% eucalyptus CNCs. The characterized using transmission electron microscopy, whereas the bionanocomposites properties studied Fourier transform infrared spectroscopy, tensile measurements, water solubility, swelling behavior, activity ( a w ). resistance (solubility behavior) nanocomposites...
Abstract Films of PBAT/TPS (poly(butylene adipate‐ co ‐terephthalate)/thermoplastic starch) (starch plasticized with glycerol containing citric and stearic acids) without 0.6 wt% starch nanoparticles were produced by extrusion. The presence during the extrusion process led to a higher degree gelatinization improving compatibility PBAT. Nanoparticles modified interaction between different components composite. hydroxyl groups interacted amylose means hydrogen bonds. In addition, structure...
Propolis is a complex mixture of resinous and balsamic material collected from the exudates plants, shoots, leaves by bees. This study evaluated red propolis extracts obtained conventional (ethanolic) extraction ultrasound-assisted six samples different regions northeastern Brazil. The total phenolic compounds flavonoids, in vitro antioxidant activity, concentration formononetin kaempferol cytotoxicity against four human tumor cell lines were determined for all twelve extracts. Significant...
The objective of this study was to investigate the feasibility incorporating mango and acerola pulps into a biodegradable matrix as source polyphenols, carotenoids, other antioxidant compounds. We also sought evaluate efficacy antioxidants in film-forming dispersions using response surface methodology design experiment. bio-based films were used pack palm oil (maintained for 45 days storage) under accelerated oxidation conditions (63% relative humidity 30 °C) simulate storage total...
There is an interest in the development of antioxidant packaging fully biodegradable to increase shelf life food products. An active film from cassava starch bio-based, incorporated with aqueous green tea extract and oil palm colorant was developed packaging. The effects additives on properties were determined by measuring mechanical, barrier thermal using a response surface methodology design experiment. bio-based films used pack butter (maintained for 45 days) under accelerated oxidation...
The objective of the present work was to study incorporation starch nanoparticles (SNP) produced by ultrasound in blends poly(butylene adipate-co-terephthalate) (PBAT) and thermoplastic (TPS). films were extrusion using varying percentages SNP (1, 2, 3, 4, 5% w/w). prepared water without addition any chemical reagent. results revealed that treatment formation less than 100 nm size an amorphous character lower thermal stability low gelatinization temperature when compared with cassava starch....
Beer has been one of the most consumed alcoholic beverages worldwide. However, incorporation adjuncts in beer can add new organoleptic and functional characteristics to beverage. For this, Beauregard sweet potato shows high potential due being a rich source starch many bioactive compounds. The aim this study was develop best process condition produce Sweet with enhanced nutritional antioxidant properties good sensory characteristics. samples showed increased activity especially β-carotene...
This work aimed to provide a biochemical characterisation of Chlorella vulgaris biomass cultivated with daily supplementation produced water. The simultaneous phytoremediation and production biomolecules bioproducts commercial interest were analysed discussed. Cultures grown in laboratory scale photobioreactors for 26 days 1.5 L BG11 medium, 50 mL non-autoclaved water (TPW) or distilled (TDW). Biomass differed among the control (3.86 g L−1), TPW (1.69 TDW (1.82 L−1). TPW-treated culture...
The aim of this study was to characterize and determine the bi-functional efficacy active packaging films produced with starch (4%) glycerol (1.0%), reinforced cellulose nanocrystals (0–1%) activated alcoholic extracts red propolis (0.4 1.0%). used in were extracted from licuri leaves. characterized using moisture, water-activity analyses water vapor-permeability tests tested regarding their total phenolic compounds mechanical properties. antimicrobial antioxidant evaluated by monitoring use...
