본 연구는 비건 인구의 증가 및 비건 문화의 확대에 발맞추어 대체육 제품에 대한 시장의 요구가 커짐에 따라, 대체육의 영양학적인 부적합의 가능성이 제시된 아미노산 조성과 아연 생체 이용률의 측면에서 대체육 제품이 동물성 육류 제품을 영양학적으로 대체할 수 있는지 평가하고자 수행되었다. 텐더 형태의 동물성 계육 제품 1종과 대체육 제품 2종을 선정하여 HPLC를 통한 아미노산 함량 및 조성측정, ICP-AES를 이용한 아연, 칼슘 등의 미량 원소 함량 측정, 아연 생체 이용률 저해 화학종인 피트산의 침전 추출 및 UV-Vis 분석을 통한 정량을 수행하고, 측정 결과를 실제 제품 섭취의 맥락에 맞추어 적용, 분석하였다. 연구 결과, 대체육 제품에서 valine, lysine 등 일부 필수 아미노산 함량이 동물성 육류 제품에 비해 부족하고, 제품을 통해 권장 섭취량을 달성하기 어려운 것으로 나타났다. 아연 생체 이용률의 경우, 칼슘에 의한 아연 생체 이용률 저해는 유의미하지 않을 것으로 분석되었으며, 같은 대체육이라 하더라도 제품 원재료의 아연 함량, 피트산 함량에 따라 낮은 단계에서부터 높은 단계까지 다양한 아연 이용률을 보였다. 따라서 아연 함량이 높고 피트산 함량이 낮은 식물성 원재료를 선정, 적절히 가공함으로 적절한 아연 생체 이용률을 달성하는 대체육 제품을 생산할 수 있을 것으로 보인다.

본 시험은 육계에 마늘 부산물을 급여하여 5주간 사육한 계육의 TBARS, WHC, 전단력, pH, 총페놀함량, 전자공여능, 육색, 관능검사 및 지방산조성을 조사하였다. 실험구는 마늘 부산물을 첨가 급여하지 않은 처리구를 대조구, 마늘 부산물 1% 급여구는 T1, 마늘 부산물 2% 급여구는 T2 그리고 마늘 부산물 5% 급여구는 T3 등 4개 처리구로 나누어 사양하였다. 계육의 TBARS, pH는 마늘 부산물 급여구에서 대조구보다 유의적으로 낮았고, 급여량이 증가할수록 더욱 낮아지는 결과를 보임으로 마늘 부산물의 급여는 계육의 저장성 개선에 도움이 되리라 생각된다. 보수성은 대조구보다 T2와 T3에서 높았다(p<0.05). 총 페놀함량과 전자공여능은 대조구보다 마늘 급여구에서 높아졌으며 마늘 부산물 급여량이 증가함에 따라 특히 T3에서 함량이 다소 증가하였다. 육색 중 적색도를 나타내는 CIE $a^*$값은 대조구보다 마늘 급여구에서 높았고, 마늘급여량에 의한 처리구간의 유의적인 변화 없이 마늘 부산물 1% 급여구부터 적색도를 높이는 결과이었고(p<0.05), CIE $L^*$값과 CIE $b^*$값은 처리구간에 유의성이 없었다. 지방산 조성 중 linoleic acid와 linolenic acid는 마늘 부산물 급여구에서 증가하였으나 palmitic acid는 감소하였다(p<0.05). 결론적으로 마늘 부산물의 급여는 pH와 TBARS가 낮아지고, 총페놀함량이 높아지고 전자공여능이 향상됨으로 계육의 저장성 개선에 도움이 되리라 생각된다.

Objective: This study was to investigate the nutrient ileal digestibility of dried mealworm (Tenebrio molitor) larvae and compare with those of three animal protein by-products in growing pigs. Methods: A total of 12 crossbred ($[Landrace{\times}Yorkshire]{\times}Duroc$) growing pigs with average body weights of $24.12{\pm}0.68kg$ were surgically equipped with simple T-cannulas after being deprived of feed for 24 h according to published surgical procedures. These pigs had a recovery period of two weeks. A total of 12 pigs were assigned to individual metabolic crates and allotted to one of four treatments with 3 replicates in a fully randomized design. Dietary treatments included the following: i) Fish meal, corn-vegetable by-product basal diet+9.95% fish meal; ii) Meat meal, corn-vegetable by-product basal diet+9.95% meat meal; iii) Poultry meal, cornvegetable by-product basal diet+9.95% poultry meal; iv) Tenebrio molitor, corn-vegetable by-product basal diet+9.95% dried Tenebrio molitor larvae. Results: Results showed that the apparent ileal digestibility (AID) of Lys was higher (p<0.05) in pigs fed Tenebrio molitor diet than that in pigs fed fish meal diet. Pigs fed Tenebrio molitor diet showed increased (p<0.05) AID of His and Arg compared to pigs fed Fish meal or Meat meal diet. The AID of Cys was increased (p<0.05) in pigs fed poultry meal and Tenebrio molitor diets compared to that in pigs fish meal diet. Pigs fed meat meal, poultry meal, and Tenebrio molitor diets showed higher (p<0.05) standardized ileal digestibility (SID) of total energy compared to pigs fed fish meal diet. The SID of Arg was higher (p<0.05) in pigs fed Tenebrio molitor diet than that in pigs fed fish meal or meat meal diet. Furthermore, pigs fed poultry meal or Tenebrio molitor diets showed increased (p<0.05) SID of Cys compared to pigs fed fish meal diet. Conclusion: In conclusion, providing pigs with diets that contained Tenebrio molitor larvae meal improved AID and SID of nutrients as well as essential and non-essential amino acids. The digestibility of dried mealworm larvae protein and its utilization in vivo are also good. Therefore, dried mealworm larvae protein can be used as protein source at 10% level in growing pigs.

Occurrences of foodborne disease outbreaks are increasing in Korea. Among the outbreaks, Salmonella, Staphylococcus aureus, Vibrio parahaemolyticus are the most important organisms and meat and meat product the major sources of infection. Hazard Analysis Critical Control Point system is a process control system designed to identify and prevent microbial and other hazards in food production. It is considered to be the best process management system by the National Advisory Committee for Microbiological Criteria for Foods, the National Academy of Science, and the Codex Alimentarius Commission. The Korean Ministry of Health and Welfare established a legal basis for the implementation of the HACCP system in Article 32-2 (Hazard Analysis Critical Control Point) of the Food Sanitation Act in December 1995. The Ministry of Agriculture and Forestry has granted research funds for the development of this model system for application to traditional food products and processed fishery products as well as to raw meats. Implementation of the HACCP system is an important step and the Korean food industry and the Government are focused on ensuring food safety in Korea.

Antimicrobial coating on chicken carcasses may reduce the effects of cross-contamination and improve product shelf-life and safety. Thyme oil was mixed at 0.5%(v/v) with a pre-gelatinized pea starch coating solution. The coating solution was spread on chicken breast meat after inoculation with selected spoilage and pathogenic bacteria. After inoculation, the chicken meats were packaged in plastic bags and stored at $4^{\circ}C$. During 12 day storage, total aerobic bacteria, lactic acid bacteria, and inoculated organisms were counted at 4 day intervals. Thyme oil treatments reduced the viability of Salmonella as well as the growth of Listeria and Pseudomonas by 2 log CFU/g, and appeared to eliminate inoculated Campylobacter during storage. The addition of thyme oil increased the viscosity of the pre-gelatinized pea starch solution. The results suggested that thyme oil inclusion in an edible starch coating may be a satisfactory delivery system to enhance the safety of processed fresh meat.

In order to improve the functional properties of several fish meat extracts as an alternate protein source, theri basic plastein reactions were evaluated. The UV absorption at 270 and 290 nm indicated that plasteins had higher amount of hydrophobic peptide or amino acid than the fish meat extracts. The water solubilities of the extracts were reduced at acidic pH. Values for the emulsifying capacity of the extracts and plasteins were over 30% although the latter showed the higher ones than the former. The osmolalities of the extracts at 1.0% concentration were 39(loach), 33(bastard halibut), 30(jacopever) and 24(crucan carp) milliosmole. Generally the slightly higher osmolalities were noted in the plasteins to be compared with the extracts. Both the extracts and plasteins exhibited a higher antioxidative effect than tocopherol. The hydrophobic amino acid which had been introduced at plastein reaction attributed the stronger antionxidative effect of its product than the extracts.

Leptin is the hormone product of the obese gene and is synthesized and secreted predominantly by white adipocytes and relates to the feedback system that regulates long-term body fat weight and composition. Therefore, the leptin gene could be an excellent candidate gene controlling fat deposition, carcass traits and meat quality in beef cattle. The objective of this study was to evaluate the association of 3 SNPs (A1127T and C1180T in exon 2 and C3100T in exon 3) in the bovine leptin gene with carcass and meat quality traits in Korean cattle. The C1180T SNP was associated with backfat thickness (BF) and marbling score (MS) (p<0.05). Animals with the genotype CC had higher BF than animals with TT genotype and higher MS compared with CT and TT genotypes. No significant associations were observed between the C3100T SNP and any carcass and meat quality traits analyzed. The effect of the A1127T SNP was not analyzed because the TT genotype was not detected and the AT genotype showed only 1.0% frequency. These results suggest that the C1180T SNP of the leptin gene may be useful as a genetic marker for carcass and meat quality traits in Korean cattle.
