신선절단 사과 제조에 있어 갈변 및 연화 억제제인 처리에 고농도 vanillin의 첨가효과를 규명하기 위하여, 절단사과에 6% 과 120 mM vanillin을 병용처리하고 플라스틱 필름으로 포장하여 에서 3주 동안 저장하면서 1주 간격으로 품질특성과 미생물 생육의 변화를 조사하였다. 신선절단 사과의 L값, 가용성 고형분 및 적정산도는 단독 처리구 보다 과 vanillin의 병용 처리구에서 감소가 촉진되었다. 총호기성미생물 및 효모와 곰팡이의

The effects of high vanillin concentration on fresh-cut apples treated with NatureSealTM were investigated Apples were sliced, treated with 6% NatureSealTM or 6% NatureSealTM + 120 mM vanillin, packaged in polyethylene bags, and stored for 3 weeks at 4C. The L value, soluble solid level and titratable acidity of fresh-cut apples treated with NatureSealTM + 120 mM vanillin during storage were lower than those of fresh-cut apples treated with NatureSealTMonly; the growth of total aerobic bacteria, yeast and molds were also more inhibited in fresh-cut apples treated with NatureSealTM + 120 mM vanillin. These results show that the addition of 120 mM vanillin inhibits the growth of microorganism but 1m detrimental effects on the quality characteristics of fresh-cut apples treated with NatureSealTM.
