“…The enrichment of T. molitor substrate (organic wheat middlings) with 75% organic olive pomace did not significantly increase the fat level of T. molitor larvae. However, the enrichment with olive pomace significantly decreased SFAs and PUFAs and increased the levels of MUFAs and n6/n3 (Ruschioni et al, 2020). Figure 1.…”

“…The n6/n3 ratio in T. molitor lipids was reported to be very high due to the low levels of the n3 fatty acids (Ravzanaadii et al, 2012;Tzompa-Sosa et al, 2014;Paul et al, 2016;Benzertiha et al, 2019a). It is reported that the addition of omega 3 fatty acids to the feeding substrates will reflect in an increase of these fatty acids in the lipids of T. molitor , Ruschioni et al, 2020. Therefore, the higher level of the n6/n3 ratio could be decreased after adjusting the substrate.…”

The aim of this review is to discuss the usage of insect fats as an energy source in animal nutrition. Insects are a rich carrier of proteins, fat, and minerals. They are successfully introduced in animal diets (poultry, swine, rabbits, fish, and pets) as a source of many nutrients, including energy and essential fatty acids (FAs). The insects’ fat content and quality are highly affected by the type of substrate provided to the insects during the rearing period. The majority of the studies have shown that insect fats may be used as promising substitutes for conventional energy resources in animal nutrition without adverse effects on growth performance and feed utilization. They can positively affect meat quality by increasing the level of long-chain polyunsaturated FAs but may also positively influence animals by regulating the gut microbiota and stimulating the immune system. In conclusion, insect fat supplementation showed promising results in terms of their application in animal nutrition. However, compared to insect protein application, very few studies have been performed on insect fats. Therefore, because of the fat quality and content of insects, there is a need to extend experimentation regarding their implementation in animals’ diets as a replacement for conventional dietary energy resources.

“…The T. molitor is recommended to be reared in the temperature range of 25–27.5°C evidenced in the literature ( Grau et al 2017 ). For the analysis in research, Ruschioni et al (2020) kept the T. molitor in a similar temperature of 28 ± 1°C and at a RH of 60 ± 5%. The same temperature of 28°C in a room where the rearing chamber was located was used in research by Li et al (2015) .…”

“… Mancini et al (2019) employed five different former foodstuff products as feeding substrates, and it was ascertained that T. molitor could be practically reared on these substrates to achieve higher nutritional values. Another feeding substrate has been studied by Ruschioni et al (2020) . They used 25% of olive pomace and 75% of wheat middlings as the best compromise between growth performance and nutritional properties.…”

The present study dealt with the influence of temperature and feed on the nutritional value of Tenebrio molitor, especially on the content of crude protein, amino acids, fat, and fatty acid profile. Tenebrio molitor larvae were kept in 15, 20, and 25°C and fed with wheat bran, lentil flour, and mixture. The parameters were analyzed by international standard methods. Generally, with an increase of the lentils in the feed, the crude protein content increased. The changes in the temperature and the feed were most pronounced on the essential amino acids Val, Arg, and Leu. The highest average fat content was determined at 20°C in insects fed with wheat bran. The lowest fat content was determined at 15°C in bran-fed insects. The dependency of fat content on the temperature in feeding with lentil flour and a mixture of wheat bran and lentil flour was statistically insignificant (P > 0.05, Kruskal–Wallis, Mann–Whitney post hoc tests). The highest content of polyene fatty acids was achieved at a rearing temperature of 15°C and the bran diet. It was concluded that a higher proportion of protein diet could increase the content of crude protein in the insects. An increase in the temperature generally leads only to a slight increase in the content of nitrogenous substances. The influence of feed on this nutritional parameter is therefore much more significant than the effect of the rearing temperature. In general, it can be stated that the feed and the temperature also significantly affect the fat content.

Edible insects are a promising and sustainable food source for humans due to their low environmental footprint, high feed conversion ratio, and high protein content. Furthermore, the nutritional profile of the edible insects can be modified depending on the provided diet. The aim of this study was to evaluate the growth performance, proximate composition, and ellagic acid accumulation in Tenebriomolitor larvae fed on corn flour media enriched with pomegranate peel. Corn flour and pomegranate peel were mixed in a 1:1 ratio (w/w) (PCM) and 50 T.molitor larvae were added to each jar. After 12 days of rearing, the weight of T.molitor larvae fed on PCM and the control increased by 88.35% and 58.6%, respectively, compared to their initial values. An increase in carbohydrate, protein and ash contents, along with a decrease in lipid content, was observed in the control diet after 12 days of feeding compared to the initial larvae. Conversely, the PCM diet exhibited an increase in ash and carbohydrate contents and a decrease in lipid and protein contents after 12 days of feeding compared to the initial larvae. Total phenolic content (TPC) of T.molitor larvae did not significantly vary when fed with the control group, while it increased on the fourth and twelfth days for larvae fed with the PCM diet. The CUPRAC antioxidant activity of larvae also increased on the fourth day of feeding on the PCM diet. Ellagic acid was not detected in larvae fed with control and initially, it accumulated in T.molitor larvae fed with PCM after 8 and 12 days of rearing, with concentrations of 92.54 and 115.6 µg/g larvae, respectively. This study highlights the importance of diet in changing the phenolic profile of T.molitor larvae, which can be used as a functional food ingredient to obtain value-added products from agricultural wastes.
