Introduction:An in-depth analysis of the core requirements for the review of roasted coffee production licenses, covering key aspects from raw material selection, processing standards to product inspection, including essential equipment configurations, common quality issues, and details of national standards. This article provides practical production standard references for coffee manufacturers, helping you master the tricks of license application and ensuring product compliance and flavor stability.
The review of roasted coffee production licenses involves multiple professional standards. This article systematically outlines the key points of full-process control from raw materials to finished products. Whether you are a startup coffee factory or an operator seeking to upgrade your existing processes, this guide will help you clarify the scope of certification, production equipment requirements, and quality inspection specifications.
The globally commercially cultivated coffee varieties are mainly concentrated within the two original species: Arabica and Canephora. Arabica comprises approximately 200 cultivars; traditional varieties such as Mocha and Bourbon yield only 700 to 1500 kilograms per hectare, while modern high-yield cultivars have increased yields to 7000 to 12000 kilograms, though with lower flavor complexity. Canephora includes only five varieties with commercial value, among which Robusta is widely used in instant coffee production. This foundational knowledge is crucial for understanding subsequent processing techniques.
Roasted coffee subject to food production licensing management specifically refers to products made from coffee beans that undergo cleaning, blending, roasting, cooling, and packaging processes. Instant coffee is not included in the review scope. In terms of product classification, based on differences in processing methods, it can be divided into two main types: roasted coffee beans and coffee powder, with the certification unit uniformly categorized as "roasted coffee."
The production process of roasted coffee begins with raw material pretreatment, requiring the use of screening equipment to remove foreign objects such as stones and metals, and grading by particle size. Some advanced equipment is also equipped with color sorting functions to pick out unripe or overripe beans. The blending stage is key to shaping flavor, where producers can adjust the proportions of coffees from different origins according to target markets—for example, wet-processed Arabica is known for its bright acidity, while Robusta features intense bitterness and earthy notes.
Temperature control during the roasting phase is crucial. The initial temperature must exceed 150°C, generating key aromatic compounds through the Maillard reaction and Strecker degradation. It is recommended to maintain a roasting time of 8 to 12 minutes, at which point the moisture in the beans has largely evaporated and the volume expands by about 60%. For the cooling process, a forced-air cooling system is recommended, though some manufacturers also use water cooling solutions with attention to hygiene risks. Final packaging must have oxygen and moisture barrier properties, with composite materials or metal cans equipped with one-way degassing valves recommended to slow down flavor loss.
The coffee powder process continues the post-treatment of roasted beans, adjusting fineness by controlling screen mesh size via grinding equipment. Common issues include overly high roasting temperatures leading to the destruction of flavor compounds, or poor packaging sealing causing oxidation and spoilage. Storage environments should maintain constant temperature and humidity, avoiding direct light exposure and temperature fluctuations.
Production enterprises must be equipped with complete workspace divisions, including separate raw material warehouses, processing areas, and packaging zones. The necessary equipment list includes screening machines, roasters, cooling devices, grinding systems, and metering sealing equipment. Review focuses not only on hardware specifications but also on preventing cross-contamination in production processes and the setup of critical control points, such as roasting temperature monitoring and packaging seal integrity testing.
Quality inspection items are carried out in accordance with the NY/T 605—2002 standard. Licensing inspections require comprehensive tests covering microbiological indicators, heavy metal residues, and caffeine content. Manufacturers are advised to establish routine quality management processes, regularly calibrate inspection instruments such as analytical balances and constant temperature drying ovens, and maintain complete batch traceability records.
Sampling regulations require randomly selecting four samples from the same batch of products, with a total weight of no less than 800 grams, and the base number must exceed 200 items. Inspection samples are to be divided into test-use and reserve groups, and sealed on-site with signatures from both parties to confirm. This process ensures the fairness and reproducibility of inspection results.
The technical details and regulatory requirements compiled in this article can serve as a reference basis for coffee production enterprises to establish standardized operating procedures. Rigorous execution at every stage—from raw material selection to end-product quality control—is the cornerstone of crafting high-quality roasted coffee.
