Characterization of films based on chitosan lactate and its blends with oxidized starch and gelatin

Preparation and physicochemistry properties of smart edible films based on gelatin–starch nanoparticles

“…The modified gelatin films exhibited higher ( P < 0.05) TS than that of pure gelatin films, and it was observed that adding the crosslinker content in films with SBN ratio from 5% to 30% did not have much effect on the TS values. The causes behind this may lie in considerably higher plasticization of the SBN by water molecules, and the TS was greatly affected by preparation temperature and relative humidity of conditioning . In general, EAB increased with SBN content in films (almost triple of that of the blank gelatin films), the highest EAB value was 31.3% for 30%SBN–Gel ( P < 0.05), which indicated that in these films, SBN seemed to act as a plasticizer which enhanced film flexibility and reduced brittleness.…”

As we know, the EAB depends on TS for many factors in a mixed system between polysaccharides and protein, including the hydroxyl groups that are available for forming hydrogen bonding between gelatin-SBN-water.…”

Enhancing mechanical properties of chitosan films via modification with vanillin

“…In recent years, more attention has been focused on the green and natural cross-linking agents, such as protein, starch and plant extracts (polyphenols and aldehyde compounds) [9,[14][15][16][17][18][19]. Vanillin, which exists in sugar beet and vanilla pods, is one of the most popular flavoring substances and it is widely used in food, beverages, perfumery and pharmaceutical industries [20][21][22].…”

Starch–gelatin film as an alternative to the use of plastics in agriculture: a review

“…Biopolymers, regardless of their application, must meet certain requirements, such as good barrier properties (water, gas, and oil), good mechanical properties (resistance, stress‐resistance, elasticity) and good visual properties (translucence, lack of color). When selecting raw materials, one should consider: cost, availability, health issues, processing, susceptibility to microbial decomposition, and bioactivity …”
