본 연구에서는 사용이 증가되고 있는 천공포장재 필름을 방울 토마토 저장에 이용하여 방울 토마토의 품질변화를 조사하였으며, 또한 세척 및 꼭지 제거의 최소가공 처리유무가 방울 토마토의 저장성에 미치는 영향 및 최적 천공포장 조건을 살펴보았다. 에틸렌 가스 및 이산화탄소는 천공필름 중 투과성이 가장 낮은 LF05 및 OPP/PE 필름구에서 상대적으로 투과성이 높은 LF10, LF20, LF40에 비해 높은 값을 보였고, 산소 분압의 경우 LF05에서
Whole and stem-off cherry tomatoes were packaged using perforated films(LF05, LF10, LF20, and LF40). Gas composition(ethylene, , and ), firmness(compression and penetration force), color, brix degree, acidity, and total microbial counts were assessed during storage at and 85% relative humidity. Gas composition varied with film gas permeability, indicating that modified atmospheric(MA) conditions were achieved. Firmness fell during storage; samples packed using LF05 showed the lowest firmness, corresponding to low gas transmission conditions. L(lightness) and a(redness) values respectively decreased and rose slightly with increasing storage time, but the b(yellowness) values fell notably. Film permeability significantly affected acidity and soluble solid levels. When LF40 packaging was used, acidity and brix scale changes were similar to those seen after PET container packaging. Total microbial counts increased with time after packaging in most films, and pretreatment differences were not significant. Microflora varied between stem on/off tomatoes. Skin wrinkling and juice appearance were common in tomatoes stored in PET containers and LF films of low gas permeabilities(LF05, LF10, and LF20). White molds were partially found on stem-on tomatoes stored using packaging systems. When film packagings were compared, LF40 was optimal, permitting minimal pretreatment yet offering maximal sanitation.
