This study uses sunflower hulls, a by-product from the snack industry, to recover both, valuable phenolic compounds and cellulose fibers, for production of antioxidant reinforced starch films as potential food packaging material. The extract provided properties with EC50 values 89 mg film/mg DPPH. fibers threefold increase in Young´s modulus. Furthermore, citric acid was added induce cross-linking polymers improve film integrity. addition induced polymer hydrolysis cross-linking, seen shift...
This study explores the preparation of antioxidant starch food packaging materials by incorporation valuable phenolic compounds extracted from sunflower hulls, which are an abundant by-product industry. The were with aqueous methanol and embedded into films. Their effect on films was investigated in terms activity, optical, thermal, mechanical, barrier properties changes molecular structure. structure affected during thermal processing resulting a decrease molar mass, smaller amylopectin...
This study showed that rice straw waste is a valuable source for the extraction of water-soluble phenolic compounds can be successfully incorporated into bioactive starch-based films. The major in extract were identified as ferulic, p-coumaric and protocatechuic acid using UHPLC-MS. Homogeneous films with antioxidant properties produced by melt blending compression molding changes physico-chemical evaluated. starch slightly reddish-colored exhibited good in-vitro antiradical scavenging...
This study demonstrates the potential of feruloylated arabinoxylan (AX) from wheat bran for preparation bioactive barrier films with antioxidant properties. We have comprehensively evaluated influence structural features and chemical acetylation AX extracted by subcritical water on their film properties, in comparison alkaline a reference endosperm AX. The degree substitution (DS) had large formation, higher DS yielded better thermal mechanical properties were significantly enhanced external...
This study explores the cascade extraction of polyphenols and pectins from apple pomace their potential application as food emulsifiers. The was achieved by a simple method using ethanol resulted in remarkable antioxidant activity. Pectic polysaccharides were sequentially extracted (5, 10 15 min) subcritical water at two different temperatures (120 °C 140 °C) three pH conditions (pH 3.0, 5.0 7.0). Acidic higher pectin yields when combined with temperature, whereas neutral less selective...
In the present study, we were able to produce composites of wheat gluten (WG) protein and a novel genetically modified potato starch (MPS) with attractive mechanical gas barrier properties using extrusion. Characterization MPS revealed an altered chain length distribution amylopectin fraction slightly increased amylose content compared wild type starch. WG different ratios plasticized either glycerol or water extruded at 110 130 °C. The nanomorphology showed having semicrystalline structure...
Root vegetables have unique techno-functional and nutritional properties however, their use in processed foods is limited to a few species, partially due lack of knowledge related the impact thermal treatments on sensory properties. This study investigated effect steaming boiling microstructure, mechanical properties, profile three model root with distinct carbohydrate composition: Jerusalem artichoke (Helianthus tuberosus L.), parsnip (Pastinaca sativa), beetroot (Beta vulgaris). Thermally...
Sweet potato (Ipomoea batatas) is a commonly cultivated root crop in tropical and subtropical regions, including Ghana. Different varieties of sweet have been bred, order to expand its utilisation within the food industrial sector. This study analysed flours made from 12 recently developed Ghanaian terms their amylose amylopectin molecular fractions chain length distribution. Starch content ranged 49 77 g/100 g dry matter, with 11 containing above 60 matter. An orange-fleshed variety,...
In this study, we combined two wheat proteins, gliadin (Gli)/glutenin (GT), and modified potato starch (MPS) into composites using extrusion. the Gli/GT–MPS composites, studied structural dynamics of proteins starch, protein–starch interactions, protein properties, composite morphology in relation to mechanical barrier properties. Materials with different ratios Gli/GT MPS were extruded either glycerol or glycerol–water at 110 130 °C. For first time, a hierarchical hexagonal structure Gli...
ABSTRACT Molecular analysis of starch structure can be used to explain and predict changes in physical properties, such as water vapor oxygen barrier properties packaging materials. Solution casting is a widely technique create films from formulations. This study compared the molecular these standard with those experimental coatings applied paper laboratory‐scale pilot‐scale trials, all three techniques using same formulation. The results revealed large differences structure, i.e.,...
Abstract Δ 7 ‐Phytosterols present in pumpkin seed oil are significant for the prevention of prostate disorders. Herbal medicines increasingly offered as dried kernels or concentrated ethanolic extracts Cucurbita pepo seeds. Until now, seeds C. have almost exclusively been used this purpose. Only a few data concerning sterol content other Cucurbitoideae available. Therefore, we isolated, identified, and quantified free esterified phytosterols 12 Cucurbita, 3 Cucumis, Citrullus oils. The...
