Gryllus bimaculatus is one of many cricket species known as field crickets. Also known as the African or Mediterranean field cricket or as the two-spotted cricket, it can be discriminated from other Gryllus species by the two dot-like marks on the base of its wings. G.bimaculatus is a subtropical insect and widely distributed from Africa to south Asia. After into the country, The species are popular for use as a food source for insectivorous animals like spiders and reptiles kept as pets. In 2016, was approved as a general food ingredient by Korean Ministry of Food and Drug Safety. However, domestic research on G.bimaculatus is still in its study is beginning stages. and analyze nutrtion elements as per dry conditions for processing&production of G.bimaculatus. The growth stage passing by 50 days after hatching was highest in general component and amino acid contents. The crickets passing by 50 days after hatching was highest 77% crude protein in condition hotair drying 60℃, 23% crude fat in condition freeze drying.

The purpose of this study is to analyze the proximate components (water, crude ash, crude protein, crude fat, and carbohydrates) and nutritive components (vitamin A, C, E, minerals, amino acids, and fatty acids) of rice flour and develop several rice bread recipes using rice flour. The water, crude ash, crude protein, crude lipid, carbohydrate contents of rice flour were measured to be 8.53%, 0.10 g, 6.80 g, 0.14 g and 84.43 g, respectively. No vitamin A was detected in the rice flour, and vitamin C and E contents were found to be 8.30 and 0.3467 mg/100 g, respectively. Calcium, potassium, magnesium, iron, and sodium contents were measured as 6.23, 65.05, 9.78, 0.17 and 2.84 mg/100 g; the large amount of potassium helps to discharge the sodium. Rice flour has nine kinds of essential amino acids in it; essential amino acids form 45.15% of rice flour’s content. which is higher than 32.3%. Fatty acids were barely detected in the rice powder; saturated fatty acids were measured as 31.25 mg/100 g, and unsaturated fatty acids as 25.54 mg/100 g. Regarding essential fatty acids, linoleic acids were measured as 41.01 mg/100 g, and linolenic acids as 2.20 mg/100 g. The researcher used rice loaf bread as the base and developed rice bread recipes using rice flour to make a total of 11 items: 8 items with 75% rice flour (rice bagel, rice sweet red-bean bread, rice butter roll bread, rice mocha bread, rice buttertop bread, rice custard cream bread, and rice streusel), 2 items with 80% rice flour (stollen and rice hobbang), and 1 item with 85% rice flour (rice donut).

본 연구는 산업 폐기물인 비지를 활용하여 부가 가치가 높은 가공식품을 개발하기 위한 일환으로 수행되었다. 즉 대두 가공 부산물인 비지를 활용하여 죽류, 음료류 및 유동 식 등의 제품으로 개발하기 위해, 초고압균질 가공 기술을 활용하여 초미세 비지 현탁액을 제조하고 추출수율, 영양 성분 및 항산화성을 확인하였다. 비지 분산액을 homogenizer 를 이용하여 1,0000 rpm에서 5분 분쇄한 후 1,000bar, 1,500bar 및 2,000bar의 압력을 가해 고압균질 가공 처리 하였다. 고압균질 가공처리한 모든 실험구가 대조군에 비 하여 추출수율이 유의적으로 증가하였다(p<0.05). 초고압 균질 처리 후 총당, 환원당 및 가용성 식이섬유의 함량은 유의적으로 증가하였으며, 불용성 식이섬유는 유의적으로 감소하였다(p<0.05). 단백질 함량과 유리아미노산 함량은 대조군보다 높은 경향을 나타내었다. 총 폴리페놀 함량은 처리 압력이 높아질수록 유의적으로 증가하였으며, ABTS 라디칼 소거능도 유의적으로 증대되었다(p<0.05). 초고압 균질 가공 기술은 비지의 영양성분과 항산화성을 증가시키 는 매우 효과적인 가공방법이며, 비지의 영양성분을 효율적 으로 활용하여 가공식품을 제조할 수 있음을 확인하였다.
