“…The Design-Expert 8.0.6 software (STAS-EASE Inc., Minneapolis, MN, USA) was employed for data analysis [19,20] . The lower and upper limits as well as coded levels of the above parameters (moisture content X 1 , preheating temperature X 2 and maximum compression force X 3 ) were selected as the independent variables and listed in Table 2.…”

Pelleting is the most extensively used thermal processing method in feed industry. In this article, a single pellet press device was developed to investigate the pelleting processing of animal feed. Effects of moisture content (10%-18% w.b.), preheating temperature (60°C-100°C) and maximum compression force (0.2-0.6 kN) on feed pellet were determined and analyzed, as well as energy consumption. The results showed that unit density, pellet hardness and energy consumption were 0.87-2.92 g/cm 3 , 1.08-4.55 kg, and 3.27-12.66 J/g, respectively. Unit density was found to increase with the increase of preheating temperature and maximum compression force, but decrease with the increase of moisture content. Pellet hardness showed a first ascending then descending trend with the increase of moisture content, but exhibited a positive relationship with both preheating temperature and maximum compression force. Energy consumption increased with the increase of maximum compression force, but exhibited descending trends with the increase of moisture content and preheating temperature. Due to its features of low cost, high efficiency and easy control, the single pellet press device has a wide application prospect in feed processing.

“…It has been found that when the moisture content is 10% w.b, the unit density decreased compared to pellets of other moisture content. The pelleting studies conducted by Guo et al [19] on four biomass grinds (barley, oat, canola and wheat straw) at different moisture contents of 9%, 12%, and 15% w.b. indicated that pellets made at 9% w.b.…”

“…It has been established that insect flour can replace fish meal in animal diets, corresponding to its amino acid profile. Insects are successfully included in the composition of food products for people, such as snacks [4,5,6]. Insects differ in their composition and structure from traditional types of feed and food raw materials.…”

“…In another variant, they are used in the form of non-processed biomass. It should be noted that in the course of well-known studies of the extrusion of feeds containing grain and insect larvae, the latter were introduced into the feed in the form of fat-free and dehydrated protein-containing flour [4,5,6] or in the form of dehydrated and crushed mass [9]. Studies on the extrusion of larvae without their pretreatment or with minimal treatment (chitin isolation) have not been carried out before [10,11,12].…”

The results of the study of the amino acid composition of compound feeds during the extrusion of wheat grain with the addition of Black Soldier Fly Larvae (Hermetia illucens L.)

The production of quality and inexpensive feed based on agricultural raw materials is the main way to increase the profitability and competitiveness of livestock production, ensuring its import substitution and high quality. It is known that in the structure of the cost of livestock products, 50-70% of all costs are accounted for by feed. Three variants of a mixture of crushed wheat grain and biomass of the black soldier fly larvae (Hermetia illucens) were extruded with the content of the latter 10, 15, and 20% by weight at different temperatures. The content of amino acids in raw materials and finished extrudate was determined. It was found that the feed mixture of crushed grain and black soldier fly larvae can be successfully extruded at a temperature of 121-135 °C. With an increase in the extrusion temperature in the range of 115-140 °C, the amino acid content in the finished extrudate decreases. The change in the content of insect larvae in the feed mixture does not affect the nature of the dependence of the amino acid content in the extrudate on the extrusion temperature and the course of the process. It was found that the content of amino acids in the extruded feed decreases with increasing speed with increasing temperature, regardless of the content of insect biomass. The rational range of the extrusion temperature of the feed mixture from wheat grain and insect larvae was determined – 121-127 °C, which ensures a reduction in the content of essential amino acids in the extrudate by no more than 30%. The extruded feed, which includes 15% of the biomass of insect larvae, contains 9.6 ± 0.13% amino acids, including 4.38 ± 2.01% of essential amino acids. The extrusion of insect larvae in a mixture with seeds of grain crops is a promising direction for improving the production of feed for fish and farm animals.

“…For qualitative grain extrusion it was necessary to moisten it that increased the cost of feed preparation [11]. The alternative method were to add other raw materials with high moisture content to grain and to extrude them jointly, which reduced the energy consumption of the process.…”

For the Baltic Sea countries edible mussel meat (Mytilus edulis L.) is a promising type of protein raw material for feed. The purpose of the study was to experimentally verify the possibility of feed mixture extrusion, including grain crops and mussel meat, and to determine rational parameters of the extrusion process. On a single screw extruder, at various temperatures, there was extruded a feed mixture containing ground wheat grain and mussel meat (10, 12.5 and 15 % by weight); and there was identified the amino acid percentage in the finished extrudate by capillary electrophoresis. According to the study results, it has been found that a feed mixture consisting of wheat grain and mussel meat could be successfully extruded at a temperature of 120-135 ºC. Mussel meat added to wheat grain significantly increased the protein percentage in the finished feed. The increase of extrusion temperature resulted in a decrease of the amino acid percentage in the finished extrudate. The change of the mussel meat percentage in the feed mixture has virtually no effect on the dependence of the amino acid percentage in the extrudate on the extrusion temperature and the process. The amino acid percentage in the extruded feed at increasing temperature decreased with an accelerated velocity, regardless of mussel meat percentage in the feed mixture. A rational temperature range has been identified for feed mixture extrusion from wheat grain and mussel meat, it was 120-125 ºC. The extrusion of mussel meat mixed with grain crops is considered to be a promising direction to improve the production of feed for fish and farm animals.
