This study investigated the effect of films treated with anti-fogging (LA) agent on the freshness extension of 'Fuji' Apples. Preference, weight loss, total ascorbic acid, sugar content, acidity, change of gas composition in package were evaluated during storage at $15^{\circ}C$. After 150 days of storage, the weight loss of apples in control (L), LA was 1.0 to 1.1%. Total ascorbic acid content of apples in control after 150 days was 2.09 mg/100g F.W, that of apple in LA was 2.47 mg/100g F.W. The titratable acidity of apple in LA was lower than that in control, while soluble solids content of LA was higher than that in control after 150 days. Ethylene gas adsorbability in control package was 192.2 ppm and that in LA was 195.7 ppm. It was verified that LA treated with anti-fogging agent are few different compare to control, but commerdity on the display in market was considered higher than that of non-treated anti-fogging agent.

As am economical and effective way of antimicrobial film fabrication , antimicrobial agents were coated on the LDPE film with a binder mediu. the fabricated films were then applied tomodified atmosphere packaging of fresh strawberries. A binder of polyamide was selected for the coating medium, based on the stability in water. 1% grapefruit seed extract-coated film showed the antimicrobial activity on the plate media against EScherichia coli, Staphylococcus aureus, bacillus subtilis , Bacillus cereus, Leuconostoc mesenteroides, Micrococcus flavus, Saccharomyces cerevisiae, while one with 10% Coptis chinesis extract inhibited only M. 림편 and one coated with 10% rheum palmatum extract did not inhibit any of 10 strains tested. The packages of fresh strawberries by using antimicrobial agents-coated films created the gas compositions of O2 1.4-5.5% and CO2 5.7-7.9%, and contributed to reduced growth of total aerobic bacteria and yeast/molds on the produced. However, their lower microbial count was not correlated directly with the reduced decay of the fruits.

To investigate the effect of packaging condition on functional MA films laminated (30CE, 50CE), corrugated paperboard box (control), 30LDPE, and 50LDPE pouches on the freshness extension of Fuji apples, the weight loss, firmness, total ascorbic acid, titratable acidity, soluble solids content and appearence were evaluated at 5$^{\circ}C$ after 75 days. Weight loss of 30CE and 50CE, and 30LD and 50LD was 0.4 to 0.5%, and 0.2%, but control was 2.7%. Firmness in film packages was higher than that of control, and CE packagings were higher than LD. Total ascorbic acid content of Fuji apple in control after 75 days was 2.12 mg%, that of control was decreased by 42%, those of LD packagings were 31% and 29%, and those of CE were 24% and 22%. Titratable acidity and soluble solids content in control changed more than that of MA film packagings. Overall appearence of 'Fuji' apples in CE packagings was better than that of control.

Weight loss of fear packed with corrugated paperboard box(FC) laminated with functional MA film after 60 days storage at 5$^{\circ}C$ was 1.0%, and that of LDPE, CE film was 0.6-0.7%, while that of control(Corrugated Paperboard box) was 2.8%. Total ascorbic acid content of pear ill MA films and FC package was higher than that of control. Titratable acid of control changed 37%, but that of the others packages changed below 27%. Soluble solid content of control changed 27%, while the others changed below 2%. Reference in overall appearence of pear were not found among packaging methods. Corrugated paperboard box(FC) laminated with Functional MA film can be used as packaging material for pear packaging.

The storage stability of fresh ginseng packaged individually in a soft film bag was more enhanced as the soft film with lower oxygen permeability was used, while the optimum water vapor permeability for enhancing the storage stability of fresh ginseng was estimated 3.5 g/m$^2$$.$day$.$90% RH when using the soft film with low oxygen permeability of 3.6∼5.4 cc/m$^2$$.$day$.$atm. The storage stability of the individually packaged fresh ginseng was also enhanced when the soft film bag was filled with carbon dioxide-oxygen-nitrogen (25:5:70) miked gas but the vacuum packaging exhibited little effect for the enhancement of storage stability of the fresh ginseng.

복숭아는 다른 과일에 비해 조직이 연약하고 저장성이 매우 낮은 여름철 과일이므로 선별, 포장 및 유통과정에 세심한 주의가 필요하다. 따라서 출하.유통시 선도를 유지시켜 유통기한을 연장시킨다면 경제적 효과가 클 것이다. 국내에서 일반화되어 있는 PE필름 밀봉 저장방식은 과실의 호흡에 의해 산소농도의 감소와 이산화탄소의 증가로 호흡이 억제되고, 이에 따라 노화가 지연됨으로 과실의 저장수명을 증가시키는 방식이며, PE필름내 기체조성에 영향을 미치는 요소는 필름의 두께와 저장온도이고 저장온도가 필름의 두께, 즉 MA효과보다 과실연화에 더 큰 영향을 미치는 것으로 알려져 있다. 이는 필름의 두께가 얇을수록 봉지 내 산소농도가 높아져 호흡대사를 촉진하기 때문인 것으로 이해된다. 과육의 연화가 시작되면서 이취를 유발하는 아세트알데히드와 에탄올의 축적이 증가한다고 보고되고 있고 이는 저장고 내 고농도의 이산화탄소 처리 시에 나타난다. 따라서 본 실험에서는 상온 2$0^{\circ}C$에서 복숭아를 0.05mm LDPE필름으로 포장하여 경도, 당도, pH를 측정하였으며 $O_2$(1, 3, 5%), $CO_2$(5, 10, 15%)를 9구분으로 환경기체를 조성하고 중심합성계획법에 의해 반응 표면분석(RSM)을 하였고 갈변도검사 결과와 함께 종합적으로 복숭아저장에 필요한 최적조건을 규명하고자 하였다.

Effect of several PLA films on strawberry packaging was investigated. Three types of PLA film (non-perforated PLA1, perforated films of PLA2 and PLA3) were used for packing strawberry and the fruit quality was measured during 6 day storage at 10. For comparison, two types of OPP/PE film (non-perforated OPP1 and perforated OPP2) were used for strawberry packaging. Weight loss of all the treatments was below 0.12% after 6 day, seeming to be in tolerable range. PLA3 package showed the best retention in fruit firmness, PLA2 and PLA3 packages the least changes in acidity, and PLA2 package gave the least changes of soluble solid content and vitamin C content. There have been no differences in surface color among packages. Perforated PLA films could be effective for use as packaging of strawberry.

산마늘은 마늘과 같이 독특한 향이 있어 입맛을 돋우며 웰빙식품으로 3월 중순에서 5월초에 채취하여 생채로 쌍을 먹거나 김치, 절임으로 생산되어 판매된다. 산마늘의 부가가치 향상을 위하여 살균소독 세척과 소포장용 필름포장방법을 구명하고자 본 실험을 수행하였다. 산마늘을 살균소독 세척수(수돗물, 0.2% 구연산 침지 후 50% 에탄올 분무처리)로 2분 세척하고 원심탈수 후, 포장필름은 $30{\mu}m$ oriented polypropylene (OPP), $30{\mu}m$ OPP 필름을 기본재료로 산소투과율 $5,000cc/m^2{\cdot}day{\cdot}atm$ (OPP_5)로 조정한 필름, $30{\mu}m$ micro perforated polypropylene (MPP) 필름에 밀봉하고, $30{\mu}m$ OPP필름에 개봉 포장하여 $4^{\circ}C$에서 42일 저장하였다. 산마늘은 구연산 침지 후 에탄올 분무세척 후 세척 전 보다 일반세균수가 1.5 log CFU/g 감소되었으며 수돗물 세척 후는 0.1 log CFU/g 정도 감소하여 수돗물 보다 구연산 침지 후 에탄올 분무에 의해 균수 감소효과가 보다 컸으며 저장기간이 경과한 후에도 그러한 경향은 유지되었다. 저장 35일 후 세척수에 관계없이 OPP 개봉과 MPP 밀봉 포장에서 의해 산마늘의 황화율과 부패율이 높게 나타났으며 OPP 밀봉에서 이취 발생 지수가 OPP_5 밀봉보다 높게 나타났다. 세척 및 포장처리에 의한 종합선도의 제한요인은 황화, 이취 및 부패취 발생 지수로 이를 종합하였을 때 산마늘의 상품성 향상을 위하여 소포장 하는 경우 구연산 침지 후 에탄올 분무 방법으로 세척한 다음 원심탈수하여 OPP_5필름으로 포장하는 것이 품질 향상에 적합하였으며 40일 이상 저장이 가능한 것으로 나타났다.
