초록

향신료의 첨가가 육제품에서 아질산염의 효과에 미치는 역할을 구명하기 위하여, 마쇄한 돈육에 8가지 향신료, ascorbic acid, nitrite를 첨가한 다음, 가열하지 않거나, $70^{\circ}C$ 30분 또는 $121^{\circ}C$ 15분 가열처리한 모델식품을 $5.5^{\circ}C$에서 12일간 저장하면서 pH, 아질산염 잔존량, 적색도, TBA값, 항생역가 등을 측정한 결과 비 가열 시료의 PH는 $5.6{\sim}5.8$로 일정하였으나 아질산염, anise, ascorbic acid, black pepper 처리구의 경우에는 5일 후에 급상승하여 12일 후에는 $6.7{\sim}7.8$로 상승하였다. 한편 $70^{\circ}C$$121^{\circ}C$로 가열구는 $5.9{\sim}6.1$로 거의 변화가 없었다. 아질산염량은 첫날에 큰 감소를 보이며, 저장기일에 따른 감소효과는 ascorbic acid구가 가장 높고, clove, eugenol, thyme도 상당한 효과를 보였으나 peppermint구는 효과가 적었다. 시료의 적색도는 대조구 보다 낮은 peppermint를 제외하면 ascorbic acid, clove, eugenol, thyme, anise, blackpepper, coriander, rosemary처리구가 대조구 보다 높았으며 그중 ascorbic acid, clove, eugenol첨가구의 경우 저장 12시간 후에 $2{\sim}3$정도 높았다. TBA가는 clove, eugenol, ascorbic acid처리구가 아질산염만 처리한 구보다 $4{\sim}6.5$정도 낮아 강력한 항산화성을 나타냈다. 미생물의 생육을 저해하는 항생역가는 Penicillium에 대해 clove, eugenol, peppermint, thyme 처리구가 강력하였으며, Salmonella에서는 모든 처리구에서 다같이 어느정도의 저해 역가를 나타냈다. 따라서 eugenol, clove, thyme oil을 육제품에 첨가하면 아질산염의 첨가량을 줄일 수 있을 것이다.

To investigate the effect of spice oils on the nitrite role in processed meat products, eight spice oils, ascorbic acid, and nitrite at different combinations were added to marcerated pork, and cooked at $70^{\circ}C$ lot 30min or $121^{\circ}C$ for 15min. The cooked sample were stored at $5.5^{\circ}C$ for 12days and pH, residual nitrite, redness, TBA value, and antimicrobial activity were analyzed. pH of the uncooked samples were stable at $5.6{\sim}5.8$ except in samples with nitrite alone, anise, ascorbic acid, and black pepper in which pH increased to $6.7{\sim}7.8$ after 5 days of storage. The pH of the cooked samples were stable at $5.9{\sim}6.1$ during the storage. Residual nitrite decreased rapidly on the first day of storage in each model. Residual nitrite decreased rapidly on the first day of storage in each model. The nitrite reducing effect was greatest in sample with ascorbic acid, followed by clove eugenol and thyme, but was small with peppermint. The redness of the sample was increased with ascorbic acid, colve, eugenol, thyme, anise, black pepper, coriander and rosemary except peppermint, specially samples with ascorbic acid, clove and eugenol were prominent. The TBA values of the samples with cloves, eugenol and ascorbic acid, stored after nine days, were $4{\sim}6.5$ lower than that of nitrite added sample and indicated strong antioxidant activity. The antimicrobial activity determined by inhibition zone, was strong in samples with clove, eugenol, peppermint, thyme, coriander, black pepper, rosemary and anise had antimicrobial activity to the Penicillium sp. Specially with clove, eugenol, peppermint and thyme, while all the samples showed $7{\sim}10mm$ inhibition zone to the Salmonella sp. The above results suggest that addition of eugenol, clove and thyme oil to the processed meat may increased the antioxidant, antimicrobial activity, and redness of the product so that could provide a way of reducing nitrite addition into meat products.
