“…The supplementation of pea protein resulted in higher dietary fat content and lower dietary carbohydrate content, which can reduce larval growth [ 47 ]. In plants, fiber is typically composed of cellulose, lignin, and hemicelluloses and the content of these components varies among vegetable species [ 48 ]. Cereals and other members of the monocot class, such as wheat and rice, contain fiber high in hemicellulose and are moderately high in lignin, while legumes, such as pea, are high in lignin and low in hemicellulose [ 48 ].…”

The use of insects as livestock feed is becoming increasingly accepted because they provide an important source of protein. The purpose of this study was to investigate the chemical composition of mealworm larvae (Tenebrio molitor L.) reared on a range of diets that differed in nutritional composition. Focus was placed on the influence of dietary protein content on larval protein and amino acid composition. For the experimental diets, wheat bran was chosen as the control substrate. The following types of flour-pea protein, rice protein, sweet lupine, and cassava, as well as potato flakes, were mixed with wheat bran and used as the experimental diets. An analysis of the moisture, protein, and fat content was then carried out for all diets and larvae. Furthermore, the amino acid profile was determined. It was shown that supplementing the feed with pea and rice protein was most suitable in terms of high protein yield in larvae (70.9–74.1% dry weight) with low fat content (20.3–22.8% dry weight). The total amino acid content was highest in larvae that were fed with a mixture of cassava flour and wheat bran (51.7 ± 0.5% dry weight), as well as the highest content of essential amino acids (30.4 ± 0.2% dry weight). Moreover, a weak correlation between larval protein content and diet was identified, yet a stronger influence of dietary fats and carbohydrates on larval composition was found. This research could result in improved formulations of artificial diets for Tenebrio molitor larvae in the future.

“…Insects serve as a food source for a variety of animals. Published studies show that whole insects contain variable but significant amounts of fiber as measured by crude fiber (CF), acid detergent fiber (ADF), and neutral detergent fiber (NDF) [Finke, 1984, cellulose and lignins whereas NDF is composed of cellulose, lignin, and hemicellulose [Van Soest and Robertson, 1977]. Although insects contain significant amounts of both ADF and NDF, the components that make up these fibers are unknown.…”

Estimate of chitin in raw whole insects

Insects contain significant amounts of fiber as measured by crude fiber, acid detergent fiber (ADF) or neutral detergent fiber (NDF). It has always been assumed that the fiber in insects represents chitin based on the structural similarity between cellulose and chitin and the fact that the ADF fraction from insects contains nitrogen. In this study, a number of insect species that are raised commercially as food for insectivores were analyzed for moisture, crude protein (nitrogen x 6.25), fat, ash, NDF, ADF, and amino acids. Additionally, the ADF fraction was analyzed for nitrogen and amino acids to determine if proteins might be present in the ADF fraction. The ADF fraction contained a significant amount of amino acids accounting for 9.3-32.7% of the ADF (by weight). The presence of amino acids in the ADF fraction means that using ADF to estimate insect chitin results in an overestimation of insect chitin content. Using ADF adjusted for its amino acid content, the estimated chitin content of these insect species ranged from 2.7-49.8 mg/kg (as is) and 11.6-137.2 mg/kg (dry matter basis). Additionally, these data suggest that for the species measured here the amount of chitin nitrogen is quite small (as a % of total nitrogen) and that crude protein (nitrogen x 6.25) provides a reasonable estimate of the true protein for most species of insects.
