The development of soft can (cooking bag) convenient snack food market

soft packaged food market can be seen everywhere now, which is changing people's dietary life. Among them, soft can is also called cooking bag and semi-rigid container convenient snack food. The industry has been formed and expanded rapidly, and its market development deserves everyone's attention

starting from the interpretation of several related definitions

1. Flexible package refers to a constant volume package whose container shape can change after filling or taking out the contents. Its materials are generally plastic film, aluminum foil, paper, fiber products and their composites

2. Flexcan is a kind of soft packaged food, which refers to a bag shaped or shaped container made of plastic film or metal foil and their composite film. After filling the processed products, it is sealed by hot melt, heated (or pressurized) and sterilized to achieve commercial sterility. Bagged food is also called cooking bag food, and shaped container food is called aerated container food, also known as semi-rigid can. Japan collectively refers to such products as "food". It is inappropriate for some enterprises in the market to call cooking bag food "vacuum packaging". Vacuum sealing after filling the cooking bag is only one of the processes to remove oxygen and reduce pressure in the bag. High temperature (or pressure) sterilization is the practical means for cooking bag food to achieve the purpose of preservation period. Add another sentence, light vacuum packaging can not save food with moisture

3. types of common soft can materials and foods

a. bagged food -- transparent bags (PET/CPP) and aluminum foil bags (PET/Al/CPP). It is suitable for preparing food, meat products, aquatic products, rice flour products and others

b. cup and plate food - transparent PP, PVDC, PP/EVOH and aluminum foil (Al/CPP), plus container cover. It is suitable for preparing food, meat products, aquatic products, rice flour products, liquid food and others

c. ligation of food -- the two ends are successively tied with aluminum clips. PVDC materials are suitable for fish ham, fish sausage, livestock ham, livestock sausage, minced meat sauce, soup, etc

4. All the above-mentioned a, B and C foods are made into ready to eat or partially prefabricated foods that are easy to circulate, safe and hygienic by industrialized processing, which are called convenientfood; It is made into snack food or snack food, which is called soft can (cooking bag) and lifestylefood

overview of the development of soft canned food market canned food has a history of more than 100 years, but the history of soft canned food is not long. In 1958, the U.S. Army Research Institute researched and developed soft cans for military supplies. In 1977, some cooking bags were approved by the food and Drug Administration (FDA) and the Department of agriculture (USDA) and officially put into production and sale. Among the large-scale commercial production of soft canned food in the world, Japan has the largest industrial scale and the most varieties. In 1968, Japan realized the commercialization of curry products packaged in cooking bags, formulated the standard of soft canned food (JAS) in 1975, and formulated the definition and manufacturing standard of soft canned food in 1977. In the future, the Japanese cooking bag food market developed rapidly, and the packaging materials, process equipment and other related supporting facilities were quite perfect and advanced

After the reform and opening up, China began to introduce and develop soft canned food production around 1980. The transparent bagged pickles of the third and fourth factories of Shanghai original pickles are listed and exported; "Taikang" introduced Japanese production lines, cooking bags, bran baking, supercritical fluid foaming new material luohanzhai and other dishes on the market; "Fish factory" ligated fish, ham and sausage were put into operation and incorporated into the city. There were also Mengzong bamboo shoots in cooking bags in Western Zhejiang mountain area. Although individual plastic utilization had incomplete incentives in different metal substitution cases, Magnolia pre-products were exported to Japan one after another, and then some were sold domestically. At the same time, some food research institutes in Shanghai, Beijing and Qingdao, as well as military supplies research institutions, plastic factories and machinery factories have successively invested in the research and development of soft canned food technology, packaging materials and equipment. The production of soft canned convenience food in China has started, and the momentum is not small. Soon, the "Xieqiao" aluminum foil bag was convenient for pickled mustard to be popular in the north and south of the river. Later, Henan "Chundu", "Shuanghui" and other brands of pork ham ligated sausage spread throughout urban and rural areas, becoming a precedent for the successful development of steamed bag food in the market. In the late 1980s, Shanghai daoxiangcun and Shanghai Food Institute successfully launched the trial production of duck gizzard liver in aluminum foil bags, and began the market development of soft canned poultry snack foods

in the mid-1980s, the Shanghai Food Institute, together with Nanyangqiao cooked meat factory and Xilinmen food factory, successively trial produced polypropylene cup lunch meat and bean paste for market. This is the first time that China has independently successfully trial produced the food with equal differential pressure heating sterilization and gas containing packaging containers. In the later stage, Shanghai boxed lactone tofu production line (first introduced by Zhabei factory and then developed by Xuhui factory) came into the market, and soon developed into dozens of lines, or even hundreds of lines. Boxed lactone tofu, which is convenient for fresh preservation, is still a common bean product

in the mid-1990s, Ningbo Lehui high-temperature pressurized sterilization boxed container instant rice came into the market, equipped with various dishes and self heating function. It is worth noting that there is little market development of instant food in gas containers in China so far. The reason is that there are few plastic composite packaging containers with good high temperature resistance and sealing performance, and the second is that it is difficult to master the equal pressure differential heating sterilization process for gas container food

with the increasing development of domestic soft can packaging materials, vacuum sealing, high-pressure sterilization and other equipment manufacturing industry, by the mid and late 1990s, all kinds of prepared food and condiment cooking bag food such as poultry, meat, aquatic products, bean products and so on have emerged in the market all over the country. Because of the advantages of normal temperature circulation like hard can heads, all supermarkets, supermarkets, convenience stores, as well as all kinds of food and grocery stores have such convenient leisure food for sale. For example, Shaanxi "yanyousi" marinated meat, pig's feet, Zhejiang Hongda roast chicken with soy sauce, Beijing roast duck, Fuliji roast chicken, Dezhou grilled chicken, Nanjing salted duck, Dongtai Feng goose, etc. are sold nationwide, and some have entered restaurants

in the past five to six years, Wenzhou Laoba egg, spicy chicken Yi, dried fish and other steamed bag snack foods have been welcomed by the youth market as soon as they appear, first "Cangnan", then "xianbali". Coupled with the competitive development of various regions, the market is not lively

it is worth mentioning that the organic graphite mined in it is stripped to produce fewer layers of thin slices. Containers of Shanghai Lehui, Kawasaki and other enterprises and soft canned foods such as bagged instant rice, porridge and dishes have entered the market in large quantities, adding a new variety of instant meal choices to families and tourist tourists in addition to instant noodles. What is more remarkable is that soft canned (cooking bags) convenience food has also become a part of China's aerospace food

at present, there are roughly 140 packaged cooked food processing plants entering the Shanghai market, and 45 enterprises in Shanghai account for 1/3; 95 companies from other places account for 2/3. There are 1300 varieties, about 1/3 of which are Western-style products and 2/3 are Chinese cooked foods. The total sales volume is said to be 160000 tons/year. Among these Chinese cooked foods, it is estimated that the high-temperature sterilization packaging products are nearly 80000 tons/year, and most of them are soft canned steamed bag foods. Shanghai brands of steamed and boiled bag food include Shangshi, Daying, ningeldest brother, Ding Yixing, Huaxia, Zhongfa, Zhende, yipinxuan, etc. there are many kinds of foreign brands. In addition to the above, there are also many kinds of foreign brands, such as Deqing "Dongli" wind goose, Wuxi "Lu Jianjian" sauce steak smoked fish, Zhejiang "Wenhu" sauce duck, Nanjing "osmanthus duck", "jinbaba", "lejiajia" poultry and duck products, Hangzhou "Louwailou" Dongpo meat, Suzhou "Jinjin" dried tofu, Wujin "Zunlong" poultry and duck Dalian "lebaijia" poultry products, Inner Mongolia "Grassland" rabbit meat, Jinan "Shengdu" soy sauce meat, Weifang "Han Laosan" grilled chicken, Chongqing "youyou" pickled pepper food, Ningbo New Year cake, Zhoushan "Tianai" aquatic products and other local famous specialty steamed bag convenience snack food have entered the Shanghai market successively, with different sales

at present, steamed bag foods marked with "25 ℃ for 6 months", "20 ℃ for 6 months", or even "20 ℃ for 120 days, 20 ℃ for 180 days" can be often seen in the retail market, and they are also displayed in the low-temperature wall type air curtain cabinet in supermarkets. The characteristics of canned soft food sterilized by high temperature liwang are that it is preserved and circulated at normal temperature, and it has reached the commercial sterile state. It is still desirable to control the temperature by cold storage circulation to prevent the bad flavor of soft canned food, which is temporarily called "cold storage soft canned (cooking bag) food", but the practice of using low temperature to extend its shelf life is unscientific

thoughts on some problems in market development

the soft can (cooking bag) convenience snack food industry has been formed, and its market development space and potential are still great. At present, the output value of hard canned food in China exceeds 20billion yuan/year. Although the total output value of soft canned food is lack of statistics, the consumption of soft canned food greatly exceeds that of local retail markets. In the future, with the increase of national income and the acceleration of urbanization, it will continue to promote the consumption growth demand of all kinds of soft canned food

continuously develop new products according to market demand, realize the industrialized production of soft cans of some Chinese cuisine, combine it with the catering industry, pursue fashion, and absorb foreign flavors and cooking skills. While enriching varieties and tastes, we should strengthen the research on the improvement of the characteristics and taste of soft canned convenience snack food, and strengthen the development of packaging materials, processing technology and equipment

as soon as possible, formulate the industry standards and health requirements, manufacturing and circulation specifications of soft canned (cooking bag) food, especially study and revise the methods of important links such as performance testing of various new packaging materials, sealing and leak detection methods, high temperature and pressure product process equipment, thermal insulation test and microbial detection, so as to ensure the safety of soft canned (cooking bag) food and expand the export market

it is suggested to establish a "soft can (cooking bag) Food Industry Association" to adapt to the cross and unique professional coordination and management between the food manufacturing industry and other industries in the first half of this year, safeguard the interests of enterprises and consumers, and jointly discuss and solve common problems in development, such as formulating industry standards, changing the current market access in which soft can (cooking bag) food can be classified as cans, It can also be classified as vague and embarrassing practices of meat products or other categories
