Review: bio-based films from zein, keratin, pea, and rapeseed protein feedstocks

Evaluation of the stability of pea and canola protein-based hydrogels in simulated gastrointestinal fluids

“…A possible explanation could be that CPI hydrogel has a lower crosslinking density than PPI hydrogel due to a higher (d) PEC-CPI beads with ratio of CPI:AG of 2:1(S10), 4:1(S12), 6:1(S14), 8:1(S16). content of glutamic acid and aspartic acid of PPI (Glu: 19% and Asp: 12%) (Shi and Dumont, 2013) than CPI (Glu: 17% and Asp: 8.32%) (Shi and Dumont, 2014). These two amino acids possess a carboxylate group which is negatively charged at the pH of gelation.…”

“…Meanwhile, 4.0 million tons of canola meal was produced as a by-product. CPI is extracted from canola meal which is currently used as source of proteins in low-value animal feed (Shi and Dumont, 2013). Only a few studies have investigated the potential of using CPI as feedstock in the synthesis of bio-based polymers.…”

Encapsulation of Lactobacillus casei ATCC 393 cells and evaluation of their survival after freeze-drying, storage and under gastrointestinal conditions

“…Pea protein isolate (PPI) is a food-grade material that has been used as additive to enrich the protein content in food industry (Shi and Dumont, 2013). To the best of our knowledge, no research has investigated the encapsulation of L. casei with pea protein isolate-alginate (PPI-alginate) based hydrogels and the survival of L. casei in freeze-dried PPI-alginate hydrogels during long-term storage.…”

Thermoplastic Blends from Albumin and Zein: Plastic Formation and Mechanical Properties Including Modeling

“…The use of albumin-based bioplastics also provides a potential for preventing the spread of bacteria, as albumin that was plasticized with glycerol did not promote the growth of bacteria (E. coli and B. subtilis) on the surface of the plastic [13]. As for zein plastic, it has been examined for potential use in both medical and food packaging applications [14,15], as its amino-acid structure promotes drug and food preservative delivery while remaining insoluble in water.…”
