Abstract

The study attempted to investigate the variation in the quality of the yellow paprika according to the duration of the yellow paprika and to use the basic materials for the development of various processed foods. The moisture content of dried paprika was 11.19% on the freeze-drying paprika (FD), and the amount of water was increased by 18.19% on the 15th day of the storage cycle. The pH has been significantly changed depending on the length of the storage period, and the sugar content in FD. The acidity contents was increased during storage in all dried paprikas showed the highest acidity, but hot air-drying paprika(HAD) was lowest in the acidity. The L value was decreased during storage period from the paprika outside and inside. The a value was not significantly dependent on the length of storage period from paprika outside and inside, and the b value increased the during storage period from paprika outside and inside. The texture of strongness, hardness, chewiness, and brittleness were decreased during storage period from all drying paprika except for FD, showing the increasing trend in cohesiveness, springiness, chewiness, and brittleness. The total aerobes changes was the lowest in HAD.

본 연구는 노란 파프리카의 건조 방법을 달리하여 저장기간에 따른 품질특성 변화를 연구하고, 노란 파프리카의 다양한 가공식품개발을 위한 기초자료로 이용하고자 하였다. 건조 파프리카의 수분함량은 FDP에서 저장 1일 차에서 11.19%이었고, 저장 15일 차에는 18.19%으로 저장기간이 길어질수록 수분함량의 증가폭이 적었다. pH 변화는 저장기간에 따라 약 pH 5 정도로 변화가 크게 없었으며, 당도 변화에서는 FDP에서 저장기간이 길어질수록 당도는 다소 높아짐을 보였다. 산도 변화에서는 FDP > CADP > HADP 순으로 저장기간이 길어질수록 모든 군에서 산도는 증가함을 보였으며 HADP에서 산도의 증가폭이 적게 나타났다. 색도 변화에서는 명도 L 값은 파프리카 외피와 내피에서 저장기간이 길어질수록 감소함을 보였으며, FDP에서 L 값이 더 높았다. a 값은 건조 파프리카 외피와 내피의 저장기간에 따른 차이가 크게 없었으며, b 값은 FDP의 외피와 내피에서 저장기간이 길어질수록 높았다. 물성측정 변화는 강도와 경도, 씹힘성, 깨짐성은 건조 파프리카 모든 군에서 저장기간이 길어질수록 감소함을 보였으며, FDP에서 높았다. 총 균수 변화는 HADP에서 저장 1일 차에 4.90 log CFU/mL으로 가장 낮았고, 저장기간이 길어질수록 증가하였으나 다른 파프리카 군에 비해 낮았다. 따라서 건조방법에 따른 노란 파프리카의 품질특성 연구는 건조된 노란 파프리카를 이용한 가공식품 및 건강식품의 개발에 기초자료가 될 것으로 생각된다.
