Abstract
The shelf-life of wrapped chewing gum(7 sticks) under the climate condition of Seoul was predicted by using moisture gain equation to reach safe moisture limits of 3.16% (dry basis). The overall water vapor permeability of multilayer packaging material was about 0.00045g water/pack day mmHg. The water activity of chewing gum at any temperature was predictable using Clausius-Clapeyron equation. The most significant loss of shelf-life was occurred between June and July, and most products reached the end of shelf-life at July and August. The product which were made in October and November had the longest shelf-life as seven months.
츄잉껌의 shelf-life 예측을 위하여 유통중인 제품과 동일한 시료를 조제하여 상대습도를 달리한 저장조건에서 포장된 츄잉껌의 수증기투과율, 흡탈습곡선의 온도의존성을 고찰하고 츄잉껌의 상품적 가치를 유지하는 수분함량
