식용곤충인 갈색거저리 유충이 식품 대체원료로써 식육에 대한 대체 가능성을 타진하고자 갈색거저리 유충 분말을 대체하지 않은 제품을 대조구로 설정하고 1%, 2%, 3% 비율로 대체한 유화소시지를 처리구로 하여 4±1℃에서 1, 8, 15, 22, 29일간 저장하면서 이화학적 특성과 관능적 특성 변화를 측정하였다. 갈색거저리 유충 분말을 첨가한 처리구의 pH는 대조구보다 증가하였고, 보수성(WHC)은 저장기간에 따라 대조구와 처리구 간 유의적인 차이는 크게 나타나지 않았으나, 대체량이 많을수록 보수성이 더 우수하였다(p<0.05). 휘발성 염기태질소(VBN), 지방산패도(TBARS) 는 대조구보다 감소하였으며, 관능검사의 경우 대조구와 유의적 차이가 나타나지 않았다(p<0.05). 따라서, 처리구가 대조구보다 우수한 품질과 저장성을 가지고 있었으며, 기호적인 측면에서도 뒤처지지 않아서 갈색거저리 유충 분말로 식육을 대체하는 것이 가능하다고 판단되어 식용곤충을 식품 대체원료로 제품화하였을 때, 식용곤충에 대한 거부감을 완화하고 소비자들에게 있어 긍정적인 인식의 변화를 이끌어낼 수 있는 기초자료를 제시할 수 있었다.

This study was conducted to examine the performance of poultry production and ammonia emissions from poultry litter when the mealworm (Tenebrio molitor L.) powder was fed to broilers and ducks. In Experiment 1, a total of 180 1-day-old broilers (Arbor acres) were allocated to two treatments with three replicates in a completely randomized design. In Experiment 2, ducks were used in the same method as in Experiment 1. The dietary treatments were as follows: basal diets as control and basal diets with 1.5% Tenebrio molitor L. powder as T1. In Experiment 1, broiler production was not affected by the addition of mealworm powder (p>0.05). Ammonia from broiler litter was observed significantly different in the two treatments at 4 and 5 weeks (p<0.05); however, in other weeks ammonia measured did not show significance different (p>0.05). In Experiment 2, feeding of mealworm powder had no statistical significance on duck productivity (p>0.05). Ammonia emissions from duck litter were not statistically significant in the two treatments at 2 to 5 weeks (p>0.05); however, there was a difference at 6 weeks (p<0.05). Therefore, the addition of mealworm powder to broiler and duck diets did not only improved weight gain and feed efficiency, but also effectively reduced ammonia in poultry litter.

This study was conducted to investigate the effects of adding Tenebrio molitor L Powder to broiler feed on fatty acid profiles in broiler breast meat. In total, 180 broiler chicks (1-day old Arbor Acres) were included. The birds were randomly divided into control and treatment groups, with 3 replicate subgroups each(30 birds per subgroup), and fed a diet for 35 days without (control) or with 1% Tenebrio molitor L powder (treatment). Among individual fatty acids, addition of Tenebrio molitor L. powder resulted in slightly higher C18:1n-9, C20:3n-3 and C20:3n-6 contents, and lower C18:2n-6 content compared withcontrols (p<0.05). No remarkable differences in total SFA and total USFA contents were found between groups. In conclusion, inclusion of Tenebrio molitor L. in broiler diets did not improve overall fatty acid profiles.
