Since 1990s, after more than ten years, the snack food market in China has undergone earth-shaking changes. As the base camp of convenience food and snack food sales, the main battlefield of supermarkets is still in coastal cities, but the market expansion space in these places has gradually narrowed. Therefore, with the development of supermarket chain industry in China, snack food has shown a trend of expansion to the surrounding areas and central and western regions, and the consumer groups of snack food have also changed, from children-oriented consumer groups to young and fashionable youth groups, with further market segmentation and expanding consumption levels. The survey on the rise of young consumers shows that young women aged 18 to 28 are still the mainstream group to guide the consumption of fashionable food, while men aged 28 to 35 pay more attention to nutrition, taste and brand, and pay less attention to price. At the same time, they are also interested in trying new brands and products, as well as foods rich in vitamins and other functional characteristics. At present, some well-known snack food manufacturers at home and abroad are vigorously promoting that snack food can become a part of a healthy and balanced diet, and snack food with low calorie, low fat and low sugar will also become the development direction of its new products. For example, in view of the popularity of puffed food, manufacturers are focusing on adding different nutritional and healthy elements according to different groups of people, different nutritional and health needs and tastes, and constantly innovating. Therefore, nutrition and health will become the development trend of snack food sold in supermarkets. In this case, young people have become the main consumers of snack foods, and fashionable snack foods have won the favor of young people with their good taste, dazzling packaging and unique and convenient eating methods. Healthy food is dominant in western countries, and low-oil potato food and snack food with fruits and vegetables as raw materials are favored by people, and the sales momentum is getting better and better, which shows that snack food has become healthier in the escalating market competition. With the development of snack food industry and the improvement of people's living standards, snack food began to be close to people's lives. However, obesity caused by unhealthy eating habits, excessive intake of high-calorie and high-fat foods and insufficient exercise, especially childhood obesity, has become the focus of urban families, and the relationship between snacks and obesity has attracted more and more attention. Therefore, healthy and functional food is the mainstream of leisure consumption. 1, "staple food" leisure food-bread/cake and biscuits have been integrated into people's daily life. According to the survey data, among all kinds of snack foods, bread/cake is the snack food with the highest comprehensive index of household consumption in Beijing, Shanghai and Guangzhou, and more than half of families often buy bread or cake. Secondly, biscuit bread/cakes and biscuits are the "staple foods" in snack foods, and their "hunger-satisfying" performance is irreplaceable by other snack foods. In many families, bread+milk has become the breakfast habit of the whole family; And some white-collar workers, at 3-4 pm on weekdays, a cup of coffee or juice with biscuits is a good afternoon tea; In addition, bread/cake/biscuit is a necessary item for many people in the process of weekend leisure, birthday party and travel. 2. Chewing gum and dried fruit foods have gradually become mainstream snack foods. Besides "staple food", chewing gum and dried fruit snacks are the most popular among all kinds of families. Compared with other kinds of snack foods, chewing gum has not entered the life of ordinary people in China for a long time, but its market development speed is amazing, so it can be said that it is a latecomer among snack foods. At present, it has become the new favorite of all kinds of families, especially high-income families. 43% of high-income families (more than 5,000 yuan) often buy chewing gum. This has a lot to do with the successful market development of several major chewing gum brands. Compared with chewing gum, dried fruit food belongs to traditional and popular recreational food, but it also has different levels. Melon seeds and peanuts are popular foods, cheap and suitable for all ages. Walnuts, pistachios and pine nuts are expensive, but they are also loved by many families because of their rich nutrition. 3. The market reaction of jelly, bacon and preserved fruit snacks is general, and the market consumption potential needs to be tapped. Although there are many varieties and brands of bacon and preserved fruit at present, the market has been in a mixed state, lacking some influential brands to lead and open up the market, so the market response is relatively dull, and the market potential needs to be tapped by manufacturers with vision and strength. Although the jelly market has been supported by well-known manufacturers such as Yilang and Qinqin, the market has been in a state of silence in the past two years. Few new manufacturers have entered the market, and old manufacturers have not taken new measures to promote market development. People's consumption awareness of jelly has gradually begun to fade. 4. Puffed food and chocolate/chocolate are favored by some families. In the survey, we divided families into four categories according to different stages of family life cycle. Among them, single and married families without children are called nested families; Families with children under 12 years old are called full nest type I families; Children/kloc-over 0/2 years old, but at school or still living at home, are called full nest second-stage families; Children have become independent, and the families formed by the elderly themselves are called empty nest families. High-income families are full of nests and become the mainstream of snack food consumption. From our investigation, it is found that the main consumers of various snack foods are families with children under 12 years old, that is, families with nests account for 41%of the whole; The high-income families in full nest period and empty nest period account for half. Most of the snack foods sold in the market are expensive. Take Shanghaojia as an example. A bag of 80 grams of the best products is sold in 5 yuan, and this consumption level is mostly accepted by families with higher incomes. When casual food lovers buy food, hygiene is the most concerned factor.
