When the night is getting deeper, Ozawa, who gets off work, often habitually goes to the Ziyan Baiwei Chicken Store at the intersection and packs a stew to take home. On the way, he will also open the service number of "Ziyan Baiwei Chicken" to check the brand dynamics. Since mid-May, Ozawa has found that the brand weekly published by Service Number has added a "food safety column" to specialize in popular science food safety knowledge. "At first, I introduced why beef glows green. Later, I taught you how to identify yuba. Recently, I shared tips on how to prevent food poisoning in hot weather." Ozawa said, "These contents are both practical and answer some of my previous questions about the product."

The design of "Food Safety Column" is actually just one of the epitome of Ziyan’s food safety work. Over the years, Ziyan Food has created a set of closed-loop quality control that runs through raw material screening, production technology, cold chain logistics, store management and even consumer feedback, so that every braised taste is more secure from the source to the tip of the tongue.

Good raw materials+good technology = good products.

"It’s delicious and suitable for eating." When talking about the reasons for loving Ziyan food, Ozawa gave the above reasons without thinking, and said, "I got off work late, and it was troublesome to fry a menu and two dishes. At this time, it was just right to take a braised taste of Ziyan home on the road." In Ozawa’s view, Ziyan food is not only delicious, but also has eye-catching new products from time to time, but among all the products, I still love husband and wife lung slices best.

According to the 2024 annual report, Ziyan Food’s annual revenue was 3.363 billion yuan, of which 991 million yuan was sold only for the single product of husband and wife lung slices, accounting for nearly 30%. The back of a good product is inseparable from the support of good raw materials and good technology. In the course of long-term business cooperation, Ziyan Food has established long-term and stable cooperative relations with a number of large suppliers, such as Wenshi, New Hope and COFCO, on the main raw materials such as whole chicken, beef and duck by-products. For non-bulk commodities with special procurement needs, Ziyan Food will lock in the production capacity resources and product prices of high-quality suppliers by signing long-term cooperation agreements and price locking agreements, thus effectively ensuring that the company can obtain sufficient high-quality raw materials at reasonable cost in time. The arrival of raw materials in the factory is only the first step. After entering the factory, each batch of raw materials has to go through the joint acceptance system of Ziyan "food safety+production+storage". Only raw materials that pass strict inspection and meet the quality standards can be allowed to enter the production process.

On the other hand, Ziyan Food puts forward precise requirements for curing time, cooking temperature and time of each product in combination with modern technology to ensure the stability of taste and quality.

In addition to inheriting Sichuan brine technology, Ziyan Food is constantly learning and researching other excellent practices. On May 28th, 2025, the Rongchang District Government of Chongqing agreed to use the name "Rongchang Braised Goose" in Ziyan’s factory. Through the standardized production system, Rongchang braised goose will reach all sales terminals directly, realizing the consistency of quality and flavor. In the research and development of new products, Ziyan is not limited to Sichuan spicy taste, but also actively expands the diversified flavors such as sour soup, rattan pepper and spiced to meet the consumption preferences in different regions of the country.

Smart cold chain logistics escorts quality.

In order to live up to the good products made by good raw materials and good technology, Ziyan Food regards product quality as the lifeline of enterprise development, and has passed ISO9001 quality management system certification, ISO22000 and HACCP food safety management system certification and FSSC22000 food safety system certification, and has strictly controlled the quality from beginning to end, creating a comprehensive quality control system covering procurement, production, warehousing, product distribution, terminal sales and other links. In 2025, Ziyan Baiwei Chicken was awarded the certificate of "Group Member of China Quality Inspection Association", and the quality management and industry standardization construction were recognized by the authority again.

At present, Ziyan Food has established five high-standard production bases in Jinan, Shandong Province, Wuhan, Hubei Province, Lianyungang, Jiangsu Province, Ningguo, Anhui Province and Chongqing. By introducing advanced production facilities and technologies, it has realized a series of automatic innovations such as batching and reporting, reduced human intervention variables, and realized visual management and detection of the production process, ensuring product consistency and production efficiency.

A good product leaving the factory is only the beginning of the test. How to make these products with short shelf life pass through the logistics link efficiently and safely and reach consumers without damage is an unavoidable issue. In this regard, Ziyan Food realizes direct, efficient and fast distribution from the factory to the store through self-built cold chain logistics fleet, and maximizes the product life cycle. At the same time, the intelligent cold chain logistics service platform is applied, and advanced technical means such as Internet of Things, GPS positioning and remote temperature monitoring are introduced. After the logistics order is automatically generated and delivered with one button, the temperature, humidity and location information of goods in transit are monitored in real time, which greatly reduces the distribution error rate, maintains the freshness and taste of products to the greatest extent, and keeps the bottom line of food safety.

The location of the above five bases also helps Ziyan Food to form an all-round supply chain system with the optimal cold chain distribution distance as the radiation radius, fast supply and maximum preservation, and realize the scene of "placing orders the day before, producing on the same day, and delivering to the store on the same day or the next day". The direct, fast and low-cost product distribution effect provides a solid supply guarantee for the rapid expansion of the company’s sales scale. Based on the strategic layout, after the completion of the project of Hainan Ziyan Food Processing and Production Base, the supply chain network of Ziyan Food will be more perfect, and the delivery timeliness is expected to be further improved.

It is worth noting that the quality control management of Ziyan Food is not static, but is constantly evolving in combination with digital and information technology. At present, Ziyan has established a set of highly integrated digital management ecology, introduced modern electronic information management systems such as SAP-ERP system, sales center system, OA system, TMS system and WMS system in food industry, realized the systematic management of core business, completed the integration of different systems, and realized the integration of financial and business information and the real-time acquisition of sales information in terminal stores. On this basis, Ziyan Food continues to explore digital applications, make cross-regional market forecasts and feed them back to production, R&D and procurement in time to improve the company’s operational efficiency.

Terminal multidimensional prevention and control food safety risk points

When the products arrive at the store, they are faced with strict management procedures. Through the deployment of high-definition network cameras, intercom multimedia terminals and other facilities, Ziyan Food has built a real-time monitoring network for stores directly managed by the headquarters, and standardized supervision of terminal operations. In terms of environmental sanitation, Ziyan Food has set up a triple guarantee with the store self-inspection system, the irregular spot check by the national inspection team and the third-party professional disinfection service. Its small cooked food window, which was first adopted and always adhered to, made the clerk and the customer have almost no contact from ordering to taking the meal, and built the last physical barrier for the safe delivery of food.

The preservation management of terminal food forms a collaborative closed loop with the upstream supply chain through digital technology. Among them, around the fresh products that require high freshness, in order to ensure the timeliness of production and supply, Ziyan established a sales forecasting system. By analyzing the medium and long-term store sales data, short-term store sales data and product market demand, it predicted the order quantity of the store on the same day, thus giving production plan suggestions for different products. The production department manually reviewed the forecast data to form a production plan and arranged production in each production base. In terms of product distribution, the company’s middle desk system summarizes the product orders sent to the company by franchised stores and direct-operated stores at the specified time, and the company’s middle desk system automatically matches the orders with the inventory. After manual review, the production bases deliver the goods according to the store orders and deliver them in cold chain.

Ziyan Food also pays great attention to consumers’ shopping experience, and has an evaluation machine in the store, which further opens the channel for consumers’ feedback to the headquarters, ensuring that customers’ feedback can be collected and responded at the first time, thus improving the quality of the store and making product optimization and service improvement more targeted.

In addition to the above links, Ziyan Food has also formulated detailed management norms in tableware disinfection, sales operation and other aspects, and implemented them through training, supervision, inspection and other forms to standardize the unified and standardized operation of stores. Among them, in 2025, Ziyan Food launched three rounds of food safety strategy training covering the whole year, involving headquarters operations, operators and stores, covering food safety standards, store management, personnel health management and other dimensions, and continuously strengthening food safety risk prevention and control capabilities.

From the rigorous screening of raw material procurement to the improvement of production process, from the intelligent management and control of cold chain logistics to the standardized operation of terminal stores, Ziyan Food’s high requirements for full-link quality control not only help itself to open up a larger market scale, but also provide a typical paradigm for the quality upgrade of traditional lo-mei flavor. Under the background of the rise of quality consumption, Ziyan Food is guarding the core of traditional flavor by means of industrialization, improving industrial efficiency by digital technology, and writing a new industry sample for the high-quality development of the table-stewed track.
