Nutritional composition and techno-functionality of non-defatted and defatted flour of edible insect Arsenura armida

Edible insects are traditional foods worldwide, and in Mexico, is a prehispanic practice. Nowadays, edible insects can be a food source for the increasing population. This research aimed to evaluate the nutritional profile, physical and techno-functional characteristics of non-defatted (NDF) and defatted (DF) flour of the edible insect Arsenura armida to use as a functional ingredient. The lipid content in NDF was 24.18%. Both flours are high in protein, 20.36% in NDF and 46.89% in DF; their soluble proteins from A. armida were classified according to their molecular weight, which ranged from 12 to 94 kDa. The physical properties suggest that both flours have good flow characteristics. Regarding techno-functional properties, DF had the highest water (275.6%) and oil (121%) holding capacity values. The viscosity values indicate that they behave as a non-Newtonian shear-thinning fluid at a high concentration (20%). Emulsion capacity values range between 78.3 and 100% in both flours, with stability between 92.4 and 100%. These flours could be a good source of nutrients, and their techno-functional properties make them a good option for animal protein substitutes.

Keunggulan ekspor antar negara dan daya saing produk UMKM Indonesia dengan Pendekatan Gravity Model

This research analyzes the potential export development of Indonesian SME products in 12 main export destination countries and determines the ranking of export destination countries. The study used a model of gravity that is distance as an indirect variable. The study results found that the average value of the development of the relative export potential of Indonesian SME products is the most in-demand are agricultural raw material products such as palm oil, coffee, and forest products. Other potential such as textile products is also a potential market share is high in the export destination country. Based on the ranking of export destination countries, the United States ranks first with a holding capacity value (Di = AiHi) of 42,895,457.11, then Japan at 10,890,740.61, then Germany with a value of 5,488,387.57. In general, export destinations in these countries are dominated by plantation products and textile products of textile products. Thus it can be concluded that Indonesian SME export products have competitiveness in 12 export destination countries.
