“…2). As a result, the respiration rate of the apple was 3.0 ml/kg•h after 21 days of storage and then slowly decreased to 1.1 ml/kg•h over the 100 days of storage [11]. This result meant that it was possible to predict the apple"s storage life during CA storage.…”

“…Weight loss changed greatly from 0% to 3.34%, while the hardness of apples decreased slightly from 16.5 N to 14.7 N, and the titratable acidity also decreased slightly from 0.411% to 0.359%. The hardness (HNESS) and titratable acidity (ACID) of the apples was calculated by (11) and (12), which were derived from the real CA storage of apples over nine months as in Fig. 4.…”

This study was carried out to indirectly predict the storage life, hardness, and acidity through respiration rate of Fuji apples in Controlled Atmosphere (CA) storage. A sensor installed inside the CA storage measured temperature, relative humidity, and gas composition data in real time. The respiration rate from five tons of apples in CA storage was calculated to predict the weight loss rate. As a result, the predicted and actual weight loss rate induced a predictable residual storage time equation that showed a very high correlation. The apple storage period showed a high reliability (R 2 =0.9322) because the predicted equation using respiration rate and number of days stored was about nine months for five tons of apples. The hardness and acidity prediction equations were derive from the quality analysis. However, correlation coefficient of hardness and acidity was low as 0.3506 and 0.3144, respectively. It was caused by insufficient quantity of analytical samples, but the decrease tendency of acidity and hardness was confirmed from the equation. As a result, these quality prediction equations could encourage CA container distribution, effective for agricultural shipment regulation and increasing ease of operations. 

“…CA 저장의 경우 저장고 내 산소(O2)농도를 낮추어 농산물의 호흡률 및 이산 화탄소(CO2) 발생을 제어함으로써 품질변화를 최소화하며 (12), MAP의 경우 유통단계의 포장용기 내 초기 기체조성 을 통하여 농산물의 품질을 유지한다 (11). 이러한 기체 제어 를 통한 저온저장은 일반 저온저장에 비하여 최대 2배 이상 저장 및 유통기간을 연장할 수 있는 효과적인 기술이지만 (13), CA 저장의 경우 국내 기술력에 한계가 있고 물류체계 의 특성상 경제성이 낮아 실제 운용에 어려움이 있다 (14). 하지만 MAP의 경우 운송물량이 많지 않은 국내 실정에 적합하여 MAP를 이용한 소포장 유통에 대한 활발한 연구 및 이용이 증가하고 있다 (3,15).…”

This study was carried out to investigate the effect of modified-atmosphere packaging (MAP) on the quality change of "Tabor" tomatoes during long-term exportation periods. Hydroponics tomatoes were harvested at the turning stage, sorted, and box packed and then packaged in nylon film with a pallet. The packaged pallet was filled with a gas composition (5% O 2 , 1% CO 2 , and 94% N 2 ) and stored at 10℃ for three weeks. The quality changes in weight loss, firmness, color, acidity, soluble solids, and microorganism growth were measured every 7 day interval. During the initial storage, the pallet-scale MAP showed slightly higher weight loss and firmness changes when compared to the conventional pallet. The total color change (ΔE) during ripening was delayed 10% under MAP storage. Acidity, soluble solids and phenolic compound contents decreased with increases in storage time regardless of the storage method; however, the quality changes of tomatoes were delayed in the MAP pallet. Furthermore, the decay rate of the pallet-scale MAP stored for 14 days was less than that of the conventional pallet, and the number of microorganisms was approximately 30% lower in the pallet-scale MAP, showing a positive effect on marketability. These results suggested that the pallet-scale MAP of tomatoes could ensure higher quality and longer storage periods than conventional pallet storage.
