本発明は食品パック用トレイ包装におけるドリップ防止
法に係わるものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drip prevention method in tray packaging for food packs.
近時包装技術、ショウケースの進歩から生鮮食品を発泡
ポリスチレン等を成型したトレイに入れて、その上から
透明フィルムでラップしたものが賞用せられ、野菜類、
魚介類、肉類、果実類等に用いられている。With recent advances in packaging technology and showcases, fresh foods have been placed in trays made of foamed polystyrene, etc., and then wrapped with transparent film.
It is used for seafood, meat, fruits, etc.
然し乍ら、之等の内、特に魚介類、肉類の冷蔵の場合に

しく商品価値を損じ、又味を落とす場合が多い。However, especially when seafood and meat are refrigerated, so-called drips are generated and accumulate at the bottom of the container, which significantly reduces the product value and taste.
ここにおいて、本発明物等は之等のトレイの１用いるこ
とにより、所謂之等のドリップを吸収して２等トレイラ

した。Here, by using one of the trays of the present invention, etc., it absorbs so-called drips and keeps the second-class tray-wrapped food beautiful for a long time, significantly increasing its commercial value and preserving its taste for a long time. We found that it is possible to maintain

等の親水性重合体、若しくは共重合体を架橋剤によって
部分的に３次元架橋したもの、若しくは上記の如き親水

す、衛生的なフィルムであれば如何なるものでも良い。The polymeric water-absorbing agent used in the present invention is usually a powdery solid substance that absorbs a relatively large amount of water and gels when it comes into contact with water, and has a water-retaining ability. , acrylic acid, or methacrylic acid or their salts, amides, or esters, and hydrophilic polymers or copolymers such as ethylene oxide, propylene oxide, sulfonated styrene, vinyl alcohol, or carboxyalkyl cellulose, etc., using a crosslinking agent. Examples include those that are partially three-dimensionally crosslinked, or those that are obtained by graft polymerizing the hydrophilic polymerizable monomers, oligomers, or cooligomers described above onto polysaccharides such as starch and cellulose. These polymeric water-absorbing agents are brought into contact with the object to be treated through a water-permeable film, and the water-permeable film is, in principle, made of polymers that have a certain degree of water resistance and that have been gelled by absorbing water. Any hygienic film that allows only water to pass through and not the water absorbing agent may be used.
その具体例としては、例えばセロファン−、グラシン紙
、パーチメント紙、不織布、微細孔を有する熱可塑性樹
脂フィルム等の各種の紙、布、合成樹脂フィルムが挙げ
られる。尚、透水性フィルムはその全体が透水性である

の場合、親水性糊料としては、カラギーナン、アルギン
酸塩、寒天、アラビヤゴム、トラカントガ１＼、ペクチ

ラツク、コンニャクマンナン及び夫等の化学修飾量等の
天然物やその変性物、その他ポリビニルアルコール、ポ
リアクリル酸等各種のものが用いられる。また更に上記
の高分子吸収剤−を゛ｎ性糊料と混和したものを透水性
フイノ１ムで挟持させてシート状としたものを用いても
良い。この場合、被処理物と接触しない面は、必らずし
も透水性である必要はなく、水不透過性のフィルム、例
えば通常のポリエチレン、ポリプロピレン、ポリ塩化ビ
ニル等の熱可塑性樹脂フィルムであってよい。Specific examples thereof include various papers, cloth, and synthetic resin films such as cellophane, glassine paper, parchment paper, nonwoven fabric, and thermoplastic resin film having micropores. Incidentally, the water-permeable film does not need to be entirely water-permeable, and the agent may be mixed with a hydrophilic paste, and the mixture may be applied to one side of the water-permeable film and brought into contact with the object to be treated. In this case, the hydrophilic thickening agents include natural products such as carrageenan, alginate, agar, gum arabic, tracantoga 1\, pectin, starch, gelatin, casein, albumin, shellac, konjac mannan, and other chemically modified substances. Modified products and various other products such as polyvinyl alcohol and polyacrylic acid are used. Furthermore, a sheet formed by mixing the above-mentioned polymeric absorbent with an adhesive paste and sandwiching it between water-permeable films may also be used. In this case, the surface that does not come into contact with the object to be treated does not necessarily have to be water-permeable, but may be a water-impermeable film, such as a thermoplastic resin film such as ordinary polyethylene, polypropylene, or polyvinyl chloride. It's fine.
この様に形成された吸水シートは、透水性フィルムは、
場合により内面に親水性糊料を被覆して、吸水力を増強
して用いるが、食品との接触面よりその水分を吸収して
、之が内部の高分子吸水剤に吸収されて、２等食品の含
水量が急かに低下し、食品は色、味等を変化させること
なく、ドリップの生成を防止して、材料に非常に好まし
い効果を与え、更にその副次的効果として食品の身が締
り、包丁の人がよい等の効果が発揮される。The water-absorbing sheet formed in this way is a water-permeable film.
In some cases, the inner surface is coated with a hydrophilic paste to enhance its water-absorbing power, but the moisture is absorbed from the surface that comes into contact with the food, and this is absorbed by the internal polymeric water-absorbing agent, resulting in a second grade. The moisture content of the food decreases rapidly, the food does not change its color, taste, etc., and prevents the formation of drips, which has a very favorable effect on the material, and as a side effect, it improves the food's texture. It has the effect of tightening the knife and making the knife easier to handle.
しかも、本発明によれば、材料食品は脱水シートを敷い
たトレイの上に載せて透明フィルムでラップで包んで１
、冷蔵すればよく、その操作は極めて簡易である。Moreover, according to the present invention, the food material is placed on a tray lined with a dehydrating sheet and wrapped with a transparent film.
It only needs to be refrigerated, and the operation is extremely simple.
