Abstract

Aims: The present study was performed in order to evaluate the effect cooking on the proximate composition and lipid oxidation of two cricket species (Hieroglyphus daganensis and Paracinema tricolor) commonly consumed in Cameroon.

Study Design: Paracinema tricolor and Hieroglyphus daganensis harvesting, cleaning, killing, cooking and drying, evaluation the effect cooking treatment on the nutritive value and lipid oxidation of these crickets species.

Place and Duration Study: University of Maroua, Cameroon and University of Yaounde I in Cameroon from November 2018 to July 2019.

Methodology: The two types of crickets after harvesting and transporting to the laboratory, were killed by freezing at -20°C for 24 hours. Common cooking methods (pan roasting and pan frying) were used to cook it. The raw, roasted and fried crickets were left at ambient temperature and then one part was transformed into powder using an electric grinder. Before analysis, the powders and the whole samples were stored at 4°C. The ash, lipid, protein, carbohydrates and crude fibber content were determined in powder samples. The oil was extracted from whole samples of raw, roasted and fried insects. Various chemical parameter (acid value, peroxide value, iodine value and thiobarbituric acid) were used to assess crickets’ lipid qualities during the cooking methods.

Results: The proximate analysis of raw samples revealed that the ash content of Paracinema tricolor and Hieroglyphus daganensis was 3.17% and 3.49% (% of dry weight) respectively. The lipid content was generally high ranging from 15.80% to 18.10% and the protein content ranged from 41.69% to 48.59%. The raw Paracinema tricolor compared to Hieroglyphus daganensis was found to have the higher contents of lipid, protein and energy. All the cooking methods increased the lipid, protein and ash contents, as well as the calorie values of the two cricket’s species, while the moisture content was reduced. The free fatty acids and thiobarbituric acid reactive substances (TBARS) values of the two crickets’ oil were significantly increased after roasting and frying processing. Iodine value decreased.

Conclusion: From these results, it can be concluded that soaking combined with frying method appeared to be the best cooking method in the two species of crickets in terms of caloric content and lipid oxidative stability.
