In addition, "retort pouch" (food) is also called retort pouch (foods) in English (hence)Japanglishis not it).Also, boil-in-bag (foods) is used interchangeably.


In Japan, according to the "Retort Pouch Food Quality Labeling Standards" (December 12, 12 Ministry of Agriculture, Forestry and Fisheries Notification No. 19), "Retort pouch foods" should be "plastic film or metal foil or a combination of these in multiple layers." It is defined as "a bag-shaped or other shaped container (limited to those having airtightness and light-shielding properties) filled with prepared food, sealed by heat melting, and sterilized by heating under pressure."[1].

Even now that many retort foods are sold, more than one-third of sales are made up of retort curry.Many for curryspicesThis is because even if a heating unpleasant odor called retort odor is generated, it does not easily affect the texture.

Adopted by the military and the Self-Defense Forces

Was the original purposeMilitary rationAlthough it is widely used by the U.S. Army and the Self-Defense Forces, it has the disadvantages of being inferior in long-term storage compared to canned foods and vulnerable to impact and damage, and as a portable food for field warfare, "Package Cannot be heated over direct fire (with boiling water)Hot waterBecause of the drawback of "to put it on or need a chemical warming agent)", it is not so popular as a military portable food in the world.

Even in the Self-Defense Forces, retort pouches and canned food were used together, but according to the Yomiuri Shimbun on February 2016, 02, the conventional canned food for combat food was used.[2]From retort pack type[3]It was reported that the Ground Self-Defense Force decided to switch to.[4]

A bag containing retort food is called a retort pouch (hereinafter abbreviated as pouch).Pouches are generally on the food sidepolypropylene, On the outsidepolyester (PET) such asSynthetic resin,Aluminum foilLaminated (laminated)the filmMade of空 気,moisture,LightIt is a device to block the food and seal the food inside.

As a food label, it cannot be labeled as "retort pouch food" unless a pouch bag made of a light-shielding material is used.[1]..Products in pouch bags that do not have light-shielding properties are referred to as "pressurized foods".[5].

Pressurized heat sterilization

As a general rule, sterilize by pressurizing and heating at 120 ° C for 4 minutes at the center of the food inside the container or in a state where heat equivalent to that is applied (the temperature and time are adjusted depending on the contents).As a result, it has the highest heat resistance among general food poisoning bacteria.Clostridium botulinumIs said to be able to sterilize.However, since there are bacteria with higher heat resistance, they are not sterile.Aged deterioration such as spoiling the flavor of food cannot be completely suppressed when stored for a long period of time.

In the industry, sterilization with an F value of about 120 to 1 is usually added with a numerical F value (F value = 1 at 5 ° C for 10 minute) indicating sterilization efficacy.

Cooking method

Cooking in traditional retort pouch foodsHot waterUse (soak in boiling water for a few minutes to heat) or transfer the contents to tableware.microwaveThe method of heating with is described as a general cooking method (of course, there is also a method of taking out the contents and heating with a frying pan or a pan).In particular, if aluminum is used for the packaging material, the microwave oven cannot be used as it is in the bag.

However, in recent years, retort pouch foods compatible with microwave ovens have become common.This was achieved by developing a special film material that does not use metals such as aluminum for the packaging material, has a steam removal mechanism that removes water vapor generated in the bag, and has excellent heat resistance and storage stability.In addition, although the short storage period was a bottleneck, products that can be stored for more than a year have also been developed.
