Post-harvest water loss and microbial infections are the root cause of rapid deterioration fresh fruit after picking process, with both environmental economic implications. Therefore, it is crucial to find solutions that can increase shelf life fruits. For this purpose, edible coatings, naturally derived non-synthetic, acknowledged as a safe strategy. Among polymeric chitosan one most effective. In work, biopolymer, produced from chitin extracted Hermetia illucens, an alternative more sustainable source than crustaceans (the commercial one), was exploited extend white red grapes. Chitosan H. illucens pupal exuviae, at 0.5 % 1 concentrations, applied on grapes, which were then stored room temperature or 4 °C. The study chemical-physical parameters such weight loss, Total Soluble Solids pH, demonstrated effectiveness even better crustacean chitosan. Moreover, analysis nutraceutical properties has natural coating improves quality beneficial effects for human health. obtained results, therefore, confirmed viability using insect-chitosan preservation food.

Hermetia illucens has received a lot of attention as its larval stage can grow on organic substrates, even those that are decomposing. Black soldier fly breeding provides variety valuable products, including frass, mixture excrements, exuviae, and leftover feedstock, be used fertilizer in agriculture. Organic fertilizers, such bringing beneficial bacteria materials into the soil, improves health fertility. This comprehensive review delves comparative analysis frass derived from larvae fed different substrates. The composition micro- macro-nutrients, pH levels, matter content, electrical conductivity, moisture proportion dry under consideration. effect feeding substrates presence potentially for plant growth within is also reported. A critical feature examined this post-application impacts crops, highlighting agricultural benefits drawbacks introducing cultivation operations. One notable categorization crops studied distinct groups, which useful to simplify comparisons future research.

Cancer is a leading cause of death worldwide, characterized by uncontrolled cell growth and multiple mutations. Chemotherapy often associated with harmful side effects, cancer cells may become resistant through various mechanisms. New approaches, which are able to address both the toxicity resistance issues chemotherapy, primary importance in research. Antimicrobial peptides (AMPs), naturally occurring molecules innate immune system all living organisms, have wide spectrum cytotoxic activities against could be promising alternative actual chemotherapeutics. Here, we tested peptide fractions, rich AMPs, extracted from hemolymph larvae insect Hermetia illucens on HT29 HCT116 human colorectal cells, observing inhibition accumulation G2/M phase increased apoptosis. Furthermore, extract induced significant cytoskeleton reorganization, resulting reduced motility. These effects were more evident fractions obtained Escherichia coli-infected larvae. The also enhanced traditional Overall, results suggest presence biologically active H. larvae, confirming that insect-derived research area oncology.

The increasing demand for chitin and chitosan is driving research to explore alternative sources crustaceans. Insects, particularly bioconverters as Hermetia illucens, are promising substitutes they process food industry waste into valuable molecules, including chitin. Chitosan can be produced by deacetylation: hot deacetylation obtain a heterogeneous chitosan, the commonly produced, cold homogeneous not widely available. two different treatments lead arrangement of amine acetyl groups in structure, affecting its molecular weight, degree, biological activity.
