Globally, there is growing interest to integrate insect-derived ingredients into food products. Knowledge of consumer perception to these food products is growing rapidly in the literature, but similar knowledge on the use of oils from African edible insects remains to be established. In this study, we (1) compared the chemistry of the oils from two commonly consumed grasshoppers, the desert locust Schistocerca gregaria and the African bush-cricket Ruspolia differens with those of olive and sesame oils; (2) compared the proximate composition of a baked product (cookie) prepared from the oils; (3) identified the potential volatiles and fatty acids contributing to the aroma and taste; and (4) examined acceptance and willingness to pay (WTP) for the baked product among consumers with no previous experience of entomophagy. Our results showed that the insect oils were compositionally richer in omega-3 fatty acids, flavonoids, and vitamin E than the plant oils. Proximate analysis and volatile chemistry revealed that differences in aroma and taste of the cookies were associated with their sources of oils. Consumers’ acceptance was high for cookies prepared with R. differens (95%) and sesame (89%) oils compared to those with olive and S. gregaria oils. Notably, cookies prepared with insect oils had more than 50% dislike in aroma and taste. Consumers’ willingness to pay for cookies prepared with insect oils was 6–8 times higher than for cookies containing olive oil, but 3–4 times lower than cookies containing sesame oil. Our findings show that integrating edible insect oils into cookies, entices people to ‘‘take the first step” in entomophagy by decreasing insect-based food products neophobia, thereby, contributing to consumers’ acceptance of the baked products. However, future research should explore the use of refined or flavored insect oils for bakery products to reduce off-flavors that might have been perceived in the formulated food products

Введение в ежедневный рацион продуктов, обогащенных эссенциальными нутриентами, является актуальной задачей стратегии здорового питания. В этой связи особое место занимают продукты переработки зерна, как основы пирамиды здорового питания. Среди наиболее востребованных незаменимых нутриентов следует выделить полиненасыщенные жирные кислоты, и особенно жирные кислоты семейства ɷ-3. Главным источником линоленовой кислоты из растительного сырья является льняное масло, которое может быть введено в виде тонкоизмельченных семян льна в состав хлебопекарной муки. Химический состав продуктов питания на зерновой основе, полученных с использованием традиционной технологии, характеризуется недостаточной сбалансированностью, невысокой пищевой и биологической ценностью. В связи с этим с целью расширения ассортимента зерновых продуктов функциональной направленности общего, диетического и профилактического назначения на основе полизерновых смесей разработаны методология управления мукомольными свойствами зернового сырья при его переработке для получения продуктов питания на зерновой основе заданного состава и свойств; показана возможность совместного размола пшенично-льняной смеси с получением муки, обогащенной незаменимыми жирными кислотами (НЖК) - омега-3 (линоленовая кислота) и омега-6 (линолевая кислота); сформированы новые виды муки, обогащенные незаменимыми жирными кислотами; определены некоторые физико-химические характеристики пшеничной муки, обогащенной НЖК; выявлены особенности хлебопекарных свойств пшенично-льняной муки. На основании динамики изменения показателя кислотного числа жира (КЧЖ) спрогнозирован срок безопасного хранения пшенично-льняной муки, который составил 9,4 месяца. The introduction of foods fortified with essential nutrients into the daily diet is an urgent task of a healthy eating strategy. In this regard, grain processing products occupy a special place, as the basis of the pyramid of healthy nutrition. Among the most demanded essential nutrients are polyunsaturated fatty acids and especially fatty acids of the ɷ-3 family. The main source of linolenic acid from plant raw materials is linseed oil, which can be added in the form of finely ground flax seeds to baking flour. The chemical composition of grain-based food products obtained using traditional technology is characterized by insufficient balance, low nutritional and biological value. In this regard, in order to expand the range of functional grain products for general, dietary and prophylactic purposes on the basis of polygrain mixtures, the following have been developed: a methodology for controlling the milling properties of grain raw materials during its processing to obtain food products based on a grain basis of a given composition and properties; the possibility of joint grinding of a wheat-flax mixture to obtain flour enriched with essential fatty acids (EFA) - omega-3 (linolenic acid) and omega-6 (linoleic acid) is shown; formed new types of flour, enriched with essential fatty acids; some physicochemical characteristics of wheat flour enriched with EFA have been determined; the features of the baking properties of wheat-flax flour are revealed. Based on the dynamics of changes in the acid number of fat (FAT), the period of safe storage of wheat-flaxseed flour was predicted, which was 9.4 months.

Functional food is a whole ingredient or a part of food that used as food for specific therapeutic purposes. It is divided into two wide categories: Conventional and modified functional foods. Conventional functional Foods are composed of natural or whole-food ingredients that provide functional substances while modified functional is food or food products in which add additional ingredients for specific health purposes. Plant-based food such as fruits, vegetables, herbs, cereals, nuts and beans contain vitamins, minerals, fiber, omega-3 fatty acids, antioxidants and phenolic compounds that play a functional role in the human body against chronic diseases including cancer, cardiovascular and GIT-related disease. Some other foods or food products like juices, dairy products, fortified eggs and seafood are composed of functional components. Fish contain omega-3 fatty acids (EPA and DHA) that are played a functional role in heart health and brain development.

Polyunsaturated Fatty Acid Content

Edible insects have been suggested as an alternative and sustainable source of fats, proteins and vitamins for humans. However, their nutritional content may largely depend on the diets offered for insects. Diet-based manipulation of fatty acids in edible insects shows promise to possibly increase their essential and long-chained polyunsaturated fatty acid content and thus further enhance human diets. We reared the edible grasshopper, Ruspolia differens, under various diets with manipulated content of fatty acids, proteins and carbohydrates. The manipulated diets dramatically altered the insects’ content and composition of fatty acids, especially the content of polyunsaturated fatty acids. Dietary fatty acids were stored largely unaltered in insects. Artificial diets with high content of linoleic, α-linolenic, eicosapentaenoic or docosahexaenoic acids, increased the content of these fatty acids in the insect tenfold. The manipulated diets also affected the omega-6/omega-3 (n-6/n-3) fatty acid ratio and developmental performance. Lack of protein and fats in the diet prolongs the development and leads to lower final weight. To achieve required n-6/n-3 ratio for human consumption and to maximise biomass gain and weight, diverse diets with a source of n-3 fatty acids and protein should be used when rearing R. differens. These results demonstrate the potential for improving human nutrition in an effective and sustainable way by producing edible insects with designed nutritional content.

Abstract This work explores the proximate composition, fatty acid profile, nutritional quality, and anti-amylase activity of propolis, royal jelly, and bee bread. The differential FTIR patterns of propolis, royal jelly, and bee bread reflect these products have different proximate compositions and nutritional properties. The values for carbohydrate, fat, and protein values of be products are similar to egg and soya. The primary fatty acids bee bread and bee propolis are palmitic, linolenic, oleic, linoleic, myristic, and docosanoic acids. The primary fatty acids in royal jelly are 2-dodecenedioic, 10-hydroxy-2-decenoic, decanedioic, linoleic, 10-hydroxydecanoic acid 3-hydroxy-decanoic acids, respectively. The propolis, bee bread, and royal jelly have well-balanced saturated, unsaturated, monounsaturated, polyunsaturated, omega-3, and omega-6 fatty acids. Their nutritional quality, including omega-6/omega-3, thrombogenicity, atherogenicity, hypocholesterolemic, nutritional value, and peroxidizability indexes, are similar to egg and soya. Fatty acids inhibit amylase by increasing Km/Vmax and decreasing Vmax and Km through an un-competition or non-competition strategy. Molecular docking, ultraviolet absorption, and fluorescence quenching analysis reveal that fatty acids interact with amino acid residues of amylase through Van der Waals and hydrogen bonds interactions. Functional fatty acids from bee products can be used in a number of food supplements, food ingredients, and medications to provide carbohydrate-degrading enzymes.
