For some time now, the topic of pre made meals has continued to attract social attention. Behind the discussion is the demand of consumers for improving food safety and nutritional quality. Recently, the National Health Commission released the draft of the "National Food Safety Standard for Pre made Vegetables", which focuses on regulating pre made vegetable products from the aspects of food safety and nutritional health. It publicly solicits opinions on issues of public concern such as raw material risk control, food additive use, and nutritional quality, and sends a positive signal to standardize the development of the industry and the high-quality development of the pre made vegetable industry. Clarifying category boundaries in discussions around pre made meals, many people are concerned about "what exactly is pre made food". Previously, there were a wide variety of pre packaged food products in the market with vague conceptual definitions. The draft for soliciting opinions on the national standard for pre packaged dishes provides a clearer definition: pre packaged dishes are made from one or more edible agricultural products and their products as raw materials, with or without the use of seasonings or other additives, without the addition of preservatives, through industrial pre-processing (such as stirring, pickling, rolling, shaping, stir frying, frying, baking, boiling, steaming, etc.), with or without seasoning packs, and can only be consumed after heating or cooking. Wang Jun, Director and Researcher of the Standard Room 2 of the National Food Safety Risk Assessment Center, introduced that the standard clearly states that pre packaged dishes do not include staple foods, clean dishes, ready to eat foods, and dishes made in central kitchens. This division is closely related to the four core characteristics of pre packaged dishes: requiring dish attributes, industrialized pre-processing, requiring heating or cooking before consumption, and possessing pre packaging attributes. Specifically, staple food products do not have dish attributes, clean dishes only clean and cut the initial processed ingredients without changing the essence of the ingredients, and ready to eat food that can be opened and eaten without heating, all of which do not meet the core requirements of pre packaged dishes; The dishes delivered by the central kitchen to its own stores belong to the extension of the catering processing link and need to be managed in accordance with the food safety regulations of the catering link and the "National Food Safety Standard General Hygiene Specification for Catering Services". Only the purchased industrialized pre packaged dishes need to comply with the pre packaged food standards, while the ready to eat foods have corresponding special food safety standards for control. Many members of the public are concerned that if these four types of food are not included in the pre packaged food management, will restaurants be allowed to freely use semi-finished products produced and stored in the central kitchen for unknown periods of time? According to relevant documents, the State Administration for Market Regulation's "Measures for the Administration of Food Business License and Filing" has clearly defined a central kitchen: a central kitchen is a business entity established by a food business enterprise, with independent premises and facilities, which centrally processes finished or semi-finished food products and only distributes them to its own chain stores for further processing before providing them to consumers. At the same time, standards such as the "Central Kitchen Operation and Management Regulations" strictly regulate the site selection, layout, facilities and equipment, as well as the entire process of processing and operation of the central kitchen. The key to clarifying the concepts of pre packaged dishes and central kitchens lies in the "chain stores of our unit" and "further processing and production". Chen Xiao, Deputy Researcher at the National Food Safety Risk Assessment Center, stated that the core function of a central kitchen is to provide standardized and intensive supply services for chain restaurants, rather than being a pre packaged food production entity for market circulation. This document relies on the concept of food safety risk analysis to refine and clarify the concept of pre made meals, which facilitates precise understanding by production enterprises, regulatory departments, and consumers. For staple foods, ready to eat foods, and central kitchen made foods, corresponding national standards are standardized, forming a complete food safety control system. Adhering to the safety bottom line of food additive use, raw material safety, nutritional quality, and consumer informed rights are the core issues that the public is most concerned about for pre made meals. The draft of the national standard for pre packaged dishes is closely related to people's livelihood needs, from additive control, raw material traceability, production and processing, label labeling to transparency in the catering process, building a full chain regulatory system and responding to the expectations of all sectors of society. Consumers generally hope to minimize the use of food additives in the production and processing of pre made dishes. In this regard, the standard clearly stipulates that preservatives shall not be used in pre made dishes, and the use of other additives shall be strictly limited. It is required to "fully evaluate the necessity of the process" and significantly narrow down the types of additives allowed to be used. Wang Jun stated that this requirement guides enterprises to achieve food safety and preservation through process upgrades from the technical source, rather than relying on additives. In terms of source control, strict standards ensure the safety of raw materials. Zhang Dequan, director and researcher of the Urban Agriculture Research Institute of the Chinese Academy of Agricultural Sciences, introduced that all types of raw materials used in pre packaged vegetables, such as livestock and poultry products, aquatic products, eggs, etc., must comply with corresponding national food safety standards, and the use of spoiled raw materials is strictly prohibited. Pesticide and veterinary drug residues, pollutants, fungal toxins, and other indicators must strictly comply with limit requirements to achieve traceable sources and full traceability, fundamentally safeguarding the safety bottom line of pre packaged vegetables. Establish health oriented standards around nutritional quality and flavor preservation. Yang Xiaoming, Director of the Standards Department of the China Light Food Industry Management Center, introduced that the standards encourage enterprises to adopt advanced technologies such as controlled atmosphere preservation, ice temperature preservation, and non thermal processing to preserve the nutrition and original taste of ingredients to the greatest extent possible and reduce nutrient loss; At the same time, advocating reducing oil, salt, and sugar, following the principle of balanced nutrition, avoiding excessive cooking, and balancing nutrition and taste needs. People are particularly concerned about whether they can clearly understand the processing and preparation methods of dishes when ordering in restaurants. In response to this, the State Council Food Safety Office, the State Administration for Market Regulation, and the Ministry of Commerce jointly issued the "Announcement on Promoting Independent Disclosure in the Catering Industry (Draft for Public Solicitation of Opinions)", which is promoting the "independent disclosure" of processing methods in the catering industry and effectively protecting consumers' right to know. To ensure consumer safety and the right to information, the standard has refined and standardized product labeling. To prevent foodborne diseases caused by insufficient heating of undercooked and incompletely cooked products, as well as to prevent excessive heating of pre cooked dishes that may affect their nutritional quality and taste, pre cooked dishes must be clearly labeled with the method of consumption. Pre processed and cooked products should be labeled with "to be heated or reheated before consumption", while undercooked products should be labeled with "to be cooked before consumption". Packaging materials that are not suitable for heating should also be indicated to prevent foodborne risks and facilitate scientific consumption by consumers. Can it still be called 'vegetable' with a shelf life of one or two years to promote industrial development? ”Unlike general food standards that do not specify shelf life, this standard explicitly requires that pre made dishes should have a shortened shelf life as much as possible, with a maximum of 12 months. Wang Jun introduced that the setting of this deadline limit is based not only on the essential attribute of pre packaged dishes as "dishes" rather than "long-term stored foods", but also on solid research data support - the drafting team conducted a systematic survey on the pre processing, storage and other parameters of more than 200 enterprises and over a thousand commercially available pre packaged dishes, taking into account the public's expectations for "freshness" and "flavor", product nutritional quality and industrial production and storage reality, and ultimately determining a maximum deadline of 12 months to achieve a balance between public demands and enterprise production and operation needs. Wang Jun further stated that even after industrial prefabrication, pre made dishes still belong to the category of dishes and need to maintain quality and flavor to the maximum extent possible. To this end, the standard specifically lists various factors that need to be comprehensively considered when setting the shelf life, encouraging enterprises to improve product flavor and retain nutritional quality by optimizing production processes, upgrading storage and transportation methods. Zhang Dequan introduced that the shelf life of food is usually determined independently by enterprises based on product characteristics, processes, and storage conditions, and is generally not included in the specific regulations of the standard. This pre packaged food standard has made clear limitations, which is a special case. It is reported that during the drafting process of the standard, more than 20000 pre packaged food sample testing data were collected through special monitoring and multi departmental collaboration. Combined with the food consumption data of Chinese residents, the risk assessment of hazard factors was completed, providing solid support for the scientificity of various regulations. Experts say that the strict limit on shelf life is a precise control of the quality of pre made vegetables. This regulation will force enterprises to improve production processes, optimize cold chain logistics, effectively enhance product taste and nutritional retention, and promote the high-quality development of the pre made vegetable industry towards "high nutrition, high quality" direction.
