Researchers of the mass. The sago beetle was formulated to have a higher nutritional value including protein, minerals, essential amino acids. And omega-3 fatty acids higher than fish oil Increase the value and commercial potential of edible insects

Associate Professor Dr. Worawan Phanphiphat, Lecturer of the School of Agricultural Technology and Food Industry As the head of the Center of Excellence in Food Technology and Innovation, revealed that he and his research team consisted of Ms. Kanittha Chinarak, Associate Professor Dr. Manat Chaichan and Assistant Professor Dr. Pichak Samphan, Center of Excellence. Technology The research was conducted to study the nutritional value of Sago palm weevil larvae cultured in farm systems in the 3 southern provinces, namely Nakhon Si Thammarat, Phatthalung, and Yala. main It contains 52.4-60.1% fat and 18.0-28.5% protein. It is also rich in minerals including potassium, phosphorus, magnesium, sodium, calcium, zinc, copper, manganese and iron. The nutrient content of the sago beetle varies from farm to farm. It depends on the recipe and how to feed the sago beetle is important.

Head of the Center of Excellence for Mass Food Technology and Innovation, said that when considering the quality of protein in cultured sago beetles, It was found that the amount of essential amino acids was lower than the reference protein set by the Food and Agriculture Organization of the United Nations. As well as having low amounts of essential fatty acids And contains the omega 6 / omega-3 fatty acid ratio that is not beneficial to health From this knowledge, in-depth research studies are conducted to develop recipes that can increase the nutritional value of the sago beetle. As well as can stimulate the growth of such insects To increase the commercial production potential of this southern edible insect By conducting a study covering total nutrient intake And focus on increasing omega-3 essential fatty acids close to fish oil Since the sago beetle has a high content of fat. And has a much shorter life cycle than deep sea fish Including studying the expression of genes involved in lipid synthesis To understand the in-depth mechanism in the metabolic system of the sago beetle.
This newly developed recipe Sago beetles were able to grow larger and heavier caterpillars than those with traditional recipes. This was able to shorten the cultivation time of sago beetles for at least 10 days, where the sago beetle had a much higher nutritional value than that of traditional food recipes. Which can increase protein content up to 40-92 percent by high quality protein As it contains All nine essential amino acids and essential amino acids have been increased by 12-48% compared to the standard protein requirements of the Food and Agriculture Organization of the United Nations. It was found that the essential amino acid content of sago beetles that were fed with this new food recipe It is 1-1.5 times higher than the reference protein, so the sago beetle is a high quality protein food source.

In the quality of the fat Sago beetles that have been fed with a new formula. The amount of omega-3 fatty acids was 10-25 times higher than that of traditional diets, while the newly fed sago beetles contained 1.24 times higher omega-3 fatty acids than fish oil. They have an omega-6 / omega-3 fatty acid ratio lower than 4/1, which indicates healthy fats. In addition, sago beetles were fed with new recipes It is also rich in minerals including potassium, phosphorus, magnesium, sodium, calcium and zinc, which are higher than those found in chicken eggs.
Associate Professor Dr. Worawan said the research has shown to increase the commercial potential of the sago beetle. To provide a future alternative food source rich in nutrients necessary for the human body. This is an in-depth research study that affects the foundation economy. Which results in career security for farmers The research team would like to thank the support for the research budget from the researcher development project and research for industry (Ph.D.) at the doctoral level.
