Notes:
Due to its easy availability, cleanliness and relative ease of cultivation, Mexican fruit fly larvae (Anastrepha ludens) were selected to study insect protein. The larvae were found to contain 79.5% moisture, 9.8% protein, 6.2% fat, 2.3% ash and 2.2% nitrogen-free extract. Larvae protein was found to be high in lysine and methionine, but low in valine, isoleucine and tryptophane, deficiencies which were reflected by a corrected PER value of 1.63. Protein concentrate and isolate prepared from larvae contained 65% and 87% protein, respectively, with corresponding recoveries of 94% and 85%. The protein solubility curve was typical, exhibiting minimum solubility of 8% at pH 5 and maximum solubility of 95% at pH 10. The protein was found to possess negligible foaming and emulsifying properties, while larvae RNA content was 1.9%, a lower value than those reported for yeasts, but higher than those reported for microscopic algae.
