Then the current methodologies for insect protein extraction are summarized including a comparison of the protein extraction yield and the final protein content of the resulting products for each method.

analysis of the interaction of peptides derived from with anticancer targetsEvaluation of the anticancer potential of peptides derived from through molecular docking.

Cancer is one of the leading causes of death worldwide. Conventional cancer therapies are not selective to cancer cells resulting in serious side effects on patients. Thus, the need for complementary treatments that improve the patient's response to cancer therapy is highly important.

Identification of antidiabetic peptides derived from in silico hydrolysis of three ancient grains: Amaranth, Quinoa and Chia.

The antidiabetic potential of bioactive peptides derived from simulated gastrointestinal digestion (SGID) of proteins present in amaranth quinoa and chia was evaluated using their bioactivity profile and theoretical interaction with DPP-IV and α-glucosidases. In silico SGID generated 52 different fragments with in vitro antidiabetic activity where fragments PW, PF, PPG, PM, SW, IW, SF, PP, PPL, PG, PY, VW and PL scored highly in bioactivity probability, with molecular weights ranging from 172.2 to 325.

Profiling modifications in physicochemical, chemical and antioxidant properties of wild blackberry ( sp.) during fermentation with EC 1118 yeast.

Unlabelled: Mexico is an extensively diverse country with a wide variety of wild species of blackberries ( spp.), which are rich in bioactive compounds, however, these fruits are underutilized. Fermentation is a process that transforms the chemical compounds of fruits and increases nutraceutical properties.

In vitro gastrointestinal digestion impact on stability, bioaccessibility and antioxidant activity of polyphenols from wild and commercial blackberries (Rubus spp.).

Gastrointestinal digestion (GID) is a physiological process that transforms the stability, bioaccessibility and antioxidant activity (AOX) of polyphenols from blackberries (Rubus spp.). This study aimed to investigate the effect of the INFOGEST® GID protocol on the phenolic stability, bioaccessibility and AOX of Mexican wild (WB) and commercial (CB) blackberries.

Salvia hispanica demonstrated to be a source of protein fractions with anticancer activity. The effect of the protein fractions <1, 1-3, and 3-5 kDa, obtained by ultrafiltration of the S. hispanica hydrolysate, was evaluated on the cellular viability of four cancer cell lines (MCF-7, Caco2, PC-3, and HepG2) and on human fibroblasts (hFB) at different concentrations (0.

Impact of gastrointestinal digestion on peptide profile and bioactivity of cooked and non-cooked oat protein concentrates.

Oat () is one of the most cultivated and consumed cereals worldwide. Recognized among cereals for its high protein content (12%-24%), it makes it an excellent source of bioactive peptides, which could be modified during processes such as heating and gastrointestinal digestion (GID). This work aims to evaluate the impact of heat treatment on the proteolysis of oat proteins and on the evolution of antioxidant peptide released during static GID, in terms of comparative analysis between cooked oat protein concentrate (COPC) and non-heated oat protein concentrate (OPC) samples.

Starch Digestion Enhances Bioaccessibility of Anti-Inflammatory Polyphenols from Borlotti Beans ().

The consumption of beans has been associated with chronic disease prevention which may be attributed to the polyphenols present in the seed coat and endosperm. However, their bioaccessibility is likely to be limited by interactions with bean matrix components, including starch, protein and fibre. The aim of this project was to evaluate the effect of domestic processing and enzymatic digestion on the bioaccessibility of polyphenols from Borlotti beans () and to test their anti-inflammatory properties in a macrophage cell model.
