Description

Micro-wave oven resin-made packaging bag, its method of heating, the fill method of filling with resin-made packaging bag to micro-wave oven and packaging body
Technical field
The present invention relates to the packaging bag for packaged food etc.
Background technology
As heating, the mess kit of food, except the mess kit such as circular bottom pot, pan of type in the past, micro-wave oven is not only also becoming widely used fixed configurations in family as mess kit as heating apparatus.
Therefore, along with pasteurization, Refrigeration Technique universal, easily with the packaged pre-cooked or half pre-cooked retort pouch food of the heating such as micro-wave oven, frozen food, refrigeration (zero is fresh-keeping) food becoming general (with reference to patent documentation 1) so that this state is edible.
In addition, in recent years, there is the trend of increase in the family at less than two mouthfuls, a family, and the demand of the food of 1 ~ 2 people improves constantly.Particularly, the elderly increases, and Baby Boomer is retired gradually, and the family of dining constantly increases at home.And, in convenience store, reflect the change of such social condition, promptly enriched the product category of refrigeration (zero the is fresh-keeping) non-staple foodstuff of divided meal etc., particularly enriched packed product category.Except these refrigeration (zero is fresh-keeping) non-staple foodstuff, dumpling, pasta etc. water dip class and the product category implementing the frozen food freezing to process with this state also increases decocting.All food is all at StoreFront or at home implement furnace run with micro-wave oven and eat.
Incidentally, in general, retort pouch food, frozen food to save as prerequisite for a long time, not within the short time cook, sell for the purpose of.
The moisture processed food sold as these markets, in the circulation style of StoreFront, adopts three kinds of following methods.
(1) circulation under normal temperature state (after aseptic filling process or distillation (レ ト Le ト) sterilization processing, circulation sale at normal temperatures)
(2) circulation under frozen state (after aseptic filling process or pasteurization process, circulation sale at 3 ~ 10 DEG C)
(3) circulation (after freezing, circulation sale in a cold or frozen state) under freezing state
In the circulation style of above-mentioned (1) ~ (3), food is all packed by bag, plastic container, tank etc.Particularly as the packaged food of the situation of above-mentioned (1), (2), in order to extend the shelf life, usually after vacuum packaging, carry out pasteurization process, and carry out providing and delivering, displaying under normal temperature or zero fresh-keeping state.
The sterile package product obtained in sterilization container that are filled with a sealing in the environment of germ-free condition by the liquid that beverage etc. has carried out sterilization processing by board-like sterilizing unit in advance in large quantities circulate at normal temperature, but the moisture processed food containing solid matter is difficult to be processed by which.
In general non-staple foodstuff or the flesh of fish, poultry meat processed goods have employed following method: to be sealed in bag, plastic container and by retort sterilisation process, the bacterial destruction in food to be carried out sterilization, or implement pasteurization process and the bacterium in food remained on below certain bacterium number, take care of at low temperatures and circulation sale in order to the propagation after suppressing, or freezing immediately after cooking and circulation sale in a cold or frozen state.
When carrying out retort sterilisation, pasteurization process, if there is head room (space) in bag or container, then sterilizing time can be caused significantly to extend because of the effect of heat insulation of air, make the mouthfeel of content food (chewing strength, tongue sense, smooth feeling etc.), taste, color and luster, fragrance occurs rotten.In addition, if utilize steam, hot water to carry out pasteurization at ambient pressure, then bag, container can break because of the het expansion of air.
Put into the freezing pasta etc. of the container of being lived by chimeric cap seal, owing to not sealing completely, so be not suitable for long-term freezen protective.Frozen food is after freezing, and the face area of food increases, and therefore, although be in low temperature environment, oil is still easily oxidized by the oxygen in container.In order to enclose deoxidizer to keep nitrogen environment, need the flange portion by laminated thin membrane cover sealing packaging containers main body and completely isolated with extraneous gas.
In order to the pasta etc. with the ripe loading container of micro-wave oven system, need a part for strip off lid film in advance and the steam produced when heating that leaves.Make the ambient temperature in container remain on the rising of about 100 DEG C interior pressures when needing microwave-oven-heating, expect the cooking length of time that thaws shortening frozen food especially.
But make except heating effect is limited except originally just there is head room, as strip off lid film in advance a part of, cannot make to remain in container more than normal pressure, therefore, cooking length of time is understood elongated naturally.
In addition, if use, the packing container with head room that container molding and lid material combine is used as packing, then when vacuum packaging, the profile of container molding can be out of shape.
And, when using packing container, when carrying out retort sterilisation process, in order to suppress distortion of vessel, need the rising along with the product temperature of the food in container and the pressure come in regulable control distillation plant that declines, and also can be subject to the harmful effect of the effect of heat insulation of above-mentioned air.
As mentioned above, packing container carries out the situation of sterilization processing after not being adapted at vacuum packaging.
Therefore, as packing timber, have employed the packaging bag of the plastic sheeting containing resistance to effect of heat basically, non-staple foodstuff or the flesh of fish, poultry meat processed goods are contained in packaging bag usually, vacuum seal is also the state that entirely eliminated inner air, thus carries out retort sterilisation process or steam, hot-water sterilization function process.
And, in general when employing the packaged food of packaging bag, in order to carry out cooking in microwave oven, temporarily from bag, food being moved in vessel by customer and heating.
Incidentally, because bag expands because of the steam produced during heating, so usually a part can be broken a seal in advance before microwave-oven-heating, or steam is left while complete cooking as micro-wave oven reply function by the exhausr port be arranged on bag.
But, must be noted that to avoid scalding when micro-wave oven takes out, need to transfer to other containers in order to edible in this condition, also there is identical use inconvenience even if take home.
Food is moved in vessel very bothersome, and the vessel after needing cleaning to use, in addition, there is quantity of refuse when vessel are disposable tablewares increase such problem.
