Edible insect Locusta migratoria shows intestinal protein digestibility and improves plasma and hepatic lipid metabolism in male rats

Exploiting Locusta migratoria as a source of bioactive peptides with anti-fibrosis properties using an in silico approach

“…In a particular case of migratory locust, Ochiai et al demonstrated that the dietary administration of insect powder to rats improved fat metabolism and promoted therapeutic/ameliorating effects against dyslipidemia. 12…”

“…In a particular case of migratory locust, Ochiai et al demonstrated that the dietary administration of insect powder to rats improved fat metabolism and promoted therapeutic/ameliorating effects against dyslipidemia. 12 Most studies concerning the bioactive properties of edible insects focused on the identification of peptides with antihypertensive, antidiabetic and antioxidant properties. 13 In a previous work, we reported that insects can also be a source of bioactive peptides with antifibrosis properties.…”

Ultrasonication and microwave pre-treated locust protein hydrolysates enhanced the storage stability of meat emulsion

“…The LoPro ( L. migratoria ) is susceptible to hydrolysis by digestive proteases, such as trypsin and chymotrypsin, released in the intestine and produce peptides and hydrophobic amino acids responsible for the antioxidant activity of the LoProHs. However, LoPro is mostly resistant to gastric pepsin due to a high level of branched-chain amino acids [9] . The published research has documented an increase in the antioxidant activity of InsecProHs after digestion simulation.…”

“…With a favourable nutritional profile, locusts are considered a healthy source of food and about 10 different species have a long history of consumption by humans and animals in about 65 countries [7] . Rats consuming acute and sub-chronic levels of locust powder showed little to no signs of toxicity, indicating the safety of the protein as a dietary ingredient [9] . The locusts ( Locusta migratoria ) are a rich source of nutrients and contain high-quality protein (∼51–71%, DWB) and fat (∼11–35%) with a favourable ratio of omega-3: omega-6 (∼0.57) and high amounts of omega-3 fatty acids (∼16%) and iron (∼0.008–0.015%) [10] , [11] , [12] .…”

Locust protein hydrolysates have the potential to enhance the storage stability of cheese

“…The highest (P < 0.05) values were recorded for the ChCh enriched with Ult-LoPHs followed by Mic-LoPHs and Not-LoPHs. With a high branched-chain amino acids content, the LoP ( L. migratoria ) is mostly resistant to the gut pepsin but susceptible to intestinal proteases, such as trypsin and chymotrypsin, and therefore digestible in the small intestine ( Ochiai et al, 2022 ). The protein is hydrolysed in the intestine and produces small peptides and hydrophobic amino acids mostly responsible for its antioxidant and radical scavenging activities ( Bhat et al, 2021a , Bhat et al, 2021b ).…”
