DIET SUPPLEMENT Essential amino acids (such as methionine, tryptophan, leucine) account for between 46 and 96% of the total amount of amino acids contained in insects, suggesting their use as a source of natural compounds for physiological activities. These, in addition to being indispensable for protein synthesis and for the correct functioning of our body, find further applications in the construction and maintenance of muscle tissue. The idea of using insect proteins in energy bars is in some ways revolutionary and is radically transforming sports nutrition. Insects possess a good nutritional profile, providing proteins and all essential amino acids, iron, zinc, and unsaturated and polyunsaturated fatty acids (PUFAs) of the omega-3 and omega-6 series. Pharmaceutical sector: The ability of insects to adapt to almost all terrestrial ecosystems and their exposure to a variety of pathogens is reflected in the expression of different types and numbers of AMPs (antimicrobial peptides) in individual species. Numerous antimicrobial compounds have been identified among the defensive peptides of insects that have a broad spectrum against gram- positive / negative bacteria and fungi. Insect defensive peptides have a unique structural topology that involves the complex arrangement of three disulfide bonds. The presence of these bonds leads to more compact structures, thus increasing stability and bioavailability for their pharmaceutical use. The insects can also be used as a vehicle for their engineering and the production of recombinant proteins and newly conceived molecules. The study of the immune response of the insect and as a vector organism for the production of antimicrobial substances and the engineering of DNA sequences that encode the identified proteins, together with the production of new modified sequences can lead to important developments in the biotechnological field. Cosmetic sector Insects have high antiradical activity and an ability to chelate ions. Antioxidant and anti- inflammatory peptides have protective effects against free radicals and can contribute to a significant reduction in the level of oxidative stress which is one of the main causes of the degenerative process associated with aging of the body and skin. These properties have been exploited in the cosmetic field for the production of some products such as face creams, anti-cellulite creams and creams that help to counteract the effects of aging and blemishes by acting on the skin and adipose tissue through the antioxidant, anti-inflammatory function of the insects. BIOPLASTIC BIOPLASTIC is a type of recyclable plastic that must have one of the following characteristics or both: ⦁ derived from renewable raw materials (materials of natural origin) ⦁ be biodegradable (of synthetic origin but degraded within a reasonable time). Among the main candidates that can take part in this role are materials made from plant cellulose and chitin, the main component of insect exoskeleton. It is a natural polysacaride consisting of N-acetyl glucosamine which can provide the derivative, polysaccharide chitosan polymer (complex sugar) biocompatible resistant, hydrophilic and oxygen permeable. By extracting this "chitosanate sugar" a thin and transparent film is obtained which has a resistance equivalent to that of aluminum, while weighing only half. This new material is flexible, resistant, cheap, can be easily shaped into complex shapes and can be transformed into compost after use. Furthermore the film is particularly suitable for food preservation, because its structure made of microfibers acts as a barrier against oxygen.
