Abstract

The OCR 06WT cricket protein concentrate production process involves cleaning crickets, mixing them with water, and finely blending them. Heat is then applied to destroy heat-sensitive microorganisms. Centrifugation separates the cricket sediment from the water, and the sediment is dried and ground into a powder. Protein is then extracted by mixing the dried cricket powder with water, adjusting the pH to 8-12, and separating the solid from the liquid. The solution is then adjusted to a pH of 4-5 for protein precipitation. The resulting protein concentrate precipitate is separated by centrifugation, washed with clean water until the pH is neutral, and finally dried and finely ground.

OCR 10KL (15/01/2569) 1. The process of producing cricket protein concentrate consists of the following steps: a. Wash the crickets to remove dirt and microorganisms. Then, mix the crickets with water in a ratio of crickets to water between 1:1 and 1:5 by weight/weight. Blend this mixture thoroughly for 3-7 minutes. b. Heat the cricket mixture prepared in step a to a temperature of 75-95 degrees Celsius for 15-35 minutes to destroy heat-sensitive microorganisms. c. Centrifugate the heated cricket mixture from step b at a speed of 8,000-10,000 rpm for 25-30 minutes to separate the cricket sediment from the water. d. Collect the sediment from step c and dry it at 60-80 degrees Celsius for 16-18 hours to remove moisture and extend its shelf life. Step J: Grind the dried cricket powder finely. Mix the cricket powder from step D with water in a ratio of cricket powder to water between 1:10 - 1:20 by weight/volume to obtain a cricket powder solution for protein extraction. Step F: Adjust the pH of the cricket powder solution from step E to the range of 8-12 using sodium hydroxide (NaOH) and stir for 1-1.5 hours at a temperature of 50-70 degrees Celsius. Step G: After the specified time, separate the solid precipitate from the dissolved liquid by centrifuging at a speed of 6,000-7,000 rpm for 20-30 minutes at 4 degrees Celsius to separate the suspended solids. Step H: Adjust the pH of the solution obtained from step G to the range of 4-5 using hydrochloric acid. (Hydrochloric acid) is used to precipitate proteins. Step 7: Separate the protein precipitate obtained from step 8 by centrifuging at 6,000-7,000 rpm for 20-30 minutes at 4°C to obtain protein concentrate. Step 8: Wash the protein concentrate precipitate from step 9 with clean water until the pH of the protein concentrate is neutral. Then, dry and grind the protein concentrate precipitate finely. 2. Method for producing protein concentrate from crickets under claim 1, where suitable crickets are classified as copper-striped crickets. 3. The process for producing cricket protein concentrate, as per claim 1, where step d. provides for, includes the additional sifting of dried cricket powder through a 60-80 mesh sieve. 4. The process for producing cricket protein concentrate according to claim 1, where step 6 involves administering sodium hydroxide at a concentration of 1-2 normal. 5. The process for producing cricket protein concentrate under claim 1, where step C involves providing hydrochloric acid at a concentration of 1 normal. 6. The process for producing protein concentrate from crickets, as per claim 1, whereby step J, the drying process of the protein concentrate sludge, is performed by freeze-drying.
