Abstract
Description
該透湿性は、青果物用調湿材と青果物とを共通する雰囲気下に置いた場合に、該雰囲気の湿度を、青果物の表面に対し実質的に結露が発生しない湿度に調節することができる透湿性である。
1)過マンガン酸カリウムを酸化剤としてシリカ又はゼオライトに担持させた化学反応型エチレン分解剤(例えば、エチレンコントロール0173(商品名)、三愛化成商事株式会社製、e-FRESH(商品名)、もりや産業株式会社製);
2)活性炭に臭素添着した化学吸着タイプのエチレンの吸収除去剤(例えば、クリスパー(商品名)、大江化学工業株式会社製);
3)TiO2又はWO3を使った光触媒分解剤、パラジウム・ニッケル又は白金粒子を担持した固体酸化物触媒分解剤、メソポーラス酸化コバルト又はシリカ担持金属触媒を利用した分解剤、銀イオン担持ゼオライト触媒を利用した分解剤;
4)酸化亜鉛97.0%以上、有機珪素化合物1.00〜1.20%を含む有機シリカ化合物微量被着酸化亜鉛粉末を含ませた防曇フィルム(例えば、ME−FRESH(商品名)フィルム、表1参照、(株)コバヤシ製);
5)特殊セラミックを含ませた防曇フィルム(例えば、食鮮フレッシュシート(商品名)、(株)エム・エイ・ティ製)。
1)活性炭(市販の活性炭、吸着容量に限界がある);
2)大谷石を含ませた防曇フィルムを利用したもの(例えば、愛菜果(商品名)、表1参照、ニプロ(株)製)。
透湿防水性フィルムの袋として厚み約10μmのポリエチレンフィルム(岩谷マテリアル社製「アイラップUF」(商品名))の袋を準備した。上述した方法を使用してこのポリエチレンフィルムの透湿性を測定したところ相対湿度で91%であった。
岩谷マテリアル社製「アイラップUF」(商品名)の代わりにKDSクリアイティブ・プロダクツ社製「Keepod」(商品名)を使用すること以外は実施例1と同様にして、下敷き用調湿シート及び上被せ用の調湿シートを作製した。実施例1と同様にして、これらを青果物保存容器に設置し、苺を青果物保存容器に収納した。
保存温度の影響を検証した。岩谷マテリアル社製「アイラップUF」(商品名)の代わりに岩谷マテリアル社製「アイラップPico230」(商品名)を使用すること以外は実施例1と同様にして、下敷き用調湿シート及び上被せ用の調湿シートを作製した。実施例1と同様にして、これらを青果物保存容器に設置し、苺(佐賀県産「ゆめのか苺」(商品名))を青果物保存容器に収納した。
透湿防水性フィルムの袋として厚み約10μmのポリエチレンフィルム(岩谷マテリアル社製「アイラップUF」(商品名))の袋内部に、3.5〜20gの吸水ポリマーゲルを入れ、開口部をヒートシールすることで密封して、調湿シートを作製した。
透湿防水性フィルムの袋として、厚み約10μmのポリエチレンフィルム(岩谷マテリアル社製「アイラップUF」(商品名))の袋内部に、3.5g〜20gの吸水ポリマーゲルを入れ、開口部をヒートシールすることで密封して、調湿シート1を作製した。
