Abstract
Protein is an important biomolecule in the human body since it has a vital role in several processes. Some sources of protein include meat, poultry, eggs, and dairy products. Among these, beef is considered as one of the largest food protein source consumed by human. However, with rapid population increase and indefinite supply of beef in the future, the need for a new source of protein has emerged. Thus, this study explores the potential of insect powder as protein source. Insects (Sphenarium purpurascens [grasshopper], Leucopholis irrorata [beetle], and Acheta domestica [cricket]) were tested for their protein content. The sample with the highest percent protein was subjected to microbiological test and chemical tests such as glutamic acid, proximate, reducing sugar, and total sugar content analyses. Protein content of the samples were found to be not significantly different with that of beef. Data showed that cricket, which was chosen for further tests due to limited sources of beetle and grasshopper, has a protein content of 46.15%. It is microbiologically safe and has a glutamic acid content of 0.60-0.80 mg/ml. Its reducing sugar and total sugar content are 2.42 ± 0.14 and 1.58 ± 0.00 mg/ml, respectively. Therefore, it can be concluded that the cricket powder has the potential to be a new food protein source.
