“…Van Broekhoven et al (2015) found similar results and concluded that the fatty acid composition in the diet influenced the larval fatty acid composition but not in the same trend and that physiological regulation of the larval fatty acid composition takes place [6]. The same statement was reported by Dreassi et al (2017) [11]. In conclusion, no or only slight linear correlations were found between the fatty acid composition of the diet and the larvae.…”

“…Fluctuations in the dietary lipid content were not translated into fluctuation of lipids in the larvae, which was confirmed by the very low Pearson correlation coefficient (R = 0.011, F(1.52) = 0.006, p = 0.937). Compared to the literature, also no significant changes in larval lipid content of the YM were detected with a dietary lipid content between 0.5% and 9.3% [11] and Oonincx et al (2015) stated that, for YM, the fatty acid profile of insects does not reflect that of the diet [9]. Behmer (2009) stated that insects regulate their nutrient intake when the opportunity is given [32].…”

“…However, a direct connection between the dietary lipid content was not found as two diets with similar lipid content provided larvae with a significantly different amount of lipids [6]. In addition, Dreassi et al (2017) and Van Broekhoven et al (2015), measured differences in the fatty acid profile when the YM was reared on different diets. These findings were partially confirmed by Oonincx et al (2015) who found only a slight variation in fatty acids C16:0 and C18:2 and stated that the larval fatty acid did change over different rearing diets but the changes did not follow the fatty acid profile changes of the diet [9].…”

“…Published data on the compositional changes in mealworms are scarce and sometimes contradictory. Some studies observed no changes in larval lipid content when providing different diets [9,11] whereas Van Broekhoven et al (2015) did measure a variable larval lipid content with different diets. However, a direct connection between the dietary lipid content was not found as two diets with similar lipid content provided larvae with a significantly different amount of lipids [6].…”

Insects are gaining interest as an alternative protein source for feed/food purposes. Although the lesser mealworm (LM) is commercially produced for human consumption, published data on its nutrient composition is scarce. This study reports on LM larvae reared on 18 different diets composed of side-streams to (1) determine the nutritional composition of the larvae and (2) study the effect of dietary changes on the larval nutrient composition. The LM larvae proved to be of good nutritional value with essential amino acids profiles comparable with that of beef and linoleic acid (C18:2) was the most dominant essential fatty acids in the larvae. The side-stream based diets varied on dry matter basis in protein (16–34%) and lipid content (2–19%). The nutrient content of the larvae reared on diets that supported good growth ranged between 37% and 49% of protein, 22% and 26% of lipid and 4% to 6% of chitin on dry matter basis. No significant correlations were identified between the larval protein or lipid content and that of the diet, but it was found between the diet nutrients and larval growth. Based on larval growth data and economic considerations, diets composed of wheat middlings with a 10–15% inclusion of rapeseed meal were identified as suitable feed for LM. Highest larval yields were obtained with diets containing 15–22% of proteins and 5–10% of lipids.

Kümes kanatlı hayvanları, tüy gelişimi, et ve yumurta üretimi için yüksek miktarda protein, aminoasit ve enerjiye gereksinim duyarlar. Bitkisel menşeyli yemlerin amino asit içerikleri, protein kaliteleri ve mineral miktarları daha düşüktür. Bu nedenle yemlerde kullanılan mısır ve soya küspesi (SK) bazen kanatlı hayvanların besin ihtiyaçlarını karşılamada yeterli olmaz. Böyle durumlarda daha pahalı olan balık unu gibi ürünler kullanılır. Hâlbuki balık unu, maya ve malt gibi ürünlerle kıyaslanabilir düzeyde besin içeriğine sahip olan yem kaynakları mevcuttur. Un kurtları, çekirgeler, solucanlar ve karasinekler kanatlı hayvanların beslenmesinde değerlendirilebilecek kaynaklardan sadece bazılarıdır. Kanatlı hayvan rasyonlarında mısır, SK ve balık unu yerine bir yem kaynağı olarak kullanım potansiyeli olan önemli böceklerden birisi de un kurdudur. Kolay üreyen ve beslenen un kurdunun (Tenebrio molitor L.) protein, yağ, enerji, yağ asitleri bakımından zengin olduğu ve kanatlı hayvan beslemede başarıyla kullanılabileceği belirtilmektedir. Bununla birlikte AB mevzuatı, üretimindeki zorluklar ve üretim maliyetinin yüksek olması gibi hususlar, kanatlı hayvanların beslenmesinde un kurdunun kullanımını sınırlandırmaktadır. Bu derleme çalışmada, un kurdunun organik kanatlı hayvan beslemede kullanım imkânları incelenmiştir.

Microalgae are considered an interesting candidate for the sustainable production of edible oils. Because microalgae contain abundant polyunsaturated fatty acids (PUFA) and have high photosynthetic rates and high oil productivity, they are superior to terrestrial oleaginous crops for producing edible oils. Microalgae are cultivated in aquatic environments, and thus, oil extraction methods for microalgae must consider the influence of water. This paper provides an overview of the suitability of microalgal lipid compositions and proposes a selection of species for edible oil production. The numerous technologies currently available for pretreatment, wet extraction and the refining of edible oils from microalgae are collated and presented, with a primary focus on the key parameters influencing process performance. Furthermore, the paper presents a proposed solution for a microalgae integrated system for edible oil production, which is a possible future direction to develop an economical and environmentally friendly process for the resource utilization of microalgal biomass. Practical Application: Microalgae might be the most promising source of edible oils, with potential applications in food industrialization, due to its rich oil content and its characteristic fatty acid composition. The review provides a selection criterion of microalgal species to help researchers exploit microalgae to produce superior edible oils for human consumption. Various process parameters and wet extraction methods are discussed that may be conducive to improving process performance and achieving high oil recovery yields. By considering the maximum utilization of microalgal biomass, an integrated system in this review would assist in economical production during further studies. Microalgae are the most promising candidates for edible oil production. Cell disruption, extraction, and refining are important processes for microalgal oils and on this basis, wet extraction and resource utilization can further promote the economic feasibility of microalgal process.
