Abstract

 

This study aims at estimating the nutritional value of fat extracted from dried caterpillars Imbrasia oyemensis. They are consumed by the Ivoirians in the West Central of Côte d’Ivoire. These caterpillars contain 7.19% water and 2.36% ash. The ash contained phosphorus 61 mg/100g of DM, calcium 51.1 mg/100g of DM, potassium 51.4 mg/100g of DM and magnesium 20.8 mg/100g of DM. The contents of iron, zinc, copper, manganese and selenium respectively were 702.14 mg/100g of DM, 111.85 mg /100g of DM, 48.09 mg/100g of DM, 3879 mg/100g of DM ,850 mg/100g of DM and 309 mg/100g of DM. The total and reducing sugar content in the flour were 0.55% and 0.08%. The fat 23.10 g for 100g of caterpillars flour contained lauric 0.6%, myristic 0.49%, stearic 9.05%, oleic 38.53%, linolenic 12.28%, palmitic 1.01%, gadoleic 0.82% and linoleic 0.58%. The saturated and unsaturated fatty acids represents 52.23% and 47.77% respectively. The saponification, iodine, acid and peroxide indices were successively 149.23%, 51.07%, 10.87% and 7.4%. Oleic acidity and insaponifiable represented as 5.6% and 1.49%. 100 g of DM of caterpillar’s flour contains 55.49 g of raw protein and the profile of amino acids had 9 essential amino acid: the leucine 6.85%, isoleucine 5.58%, lysine 8.98%, threonine 7.99%, valine 6.11%, methionine + cystéine 0.418% and phenylalanine+ tyrosine 8.83%. The non-essential amino acid were: histidine 12%, tryptophan 2.08%, serine 6.12%, glycine 7.99%, proline 5.92% and alanine 7.04%. The energetically value of 100 g of dry matter was 477 Kcal which can be compared with fish and meat value. Caterpillars can be animal protein source for future consumption.

 

Key words: Fatty acids, amino acids, entomophagy, Imbrasia oyemensis, nutritional value.
