1. Product Basic Description This product is a food-grade silica adsorbent for beer specially developed by Zhongqi Guangdong Silicon Material Co., Ltd. for the beer brewing industry. Its core component is high-purity amorphous silica, which forms a porous network structure through a special preparation process, with an ultra-large specific surface area (≥600㎡/g) and excellent pore volume performance. As a dedicated adsorbent for beer brewing, the product complies with GB 25576-2020 National Food Safety Standard for Food Additives - Silica and relevant food contact requirements of FDA and EU. It is free of heavy metal residues and peculiar smells, and can efficiently adsorb proteins, colloidal particles and polyphenols in beer without affecting the original flavor and nutritional components of beer, making it a core auxiliary material for improving beer quality. The product has significant core advantages: First, high adsorption efficiency, which can adsorb 15%-20% of target impurities relative to its own weight per unit dosage; Second, excellent dispersibility, which can quickly and evenly disperse in the beer system to avoid insufficient local adsorption; Third, strong stability, which maintains stable performance in the acid-base environment and temperature range (0-80℃) of beer brewing, with no risk of dissolution or degradation. 2. Application Instructions 1. Core Application Scenarios This product is widely applicable to various beer brewing processes, with core applications focusing on two key links: First, beer clarification and adsorption. It is added after fermentation and before filtration. By adsorbing heat-coagulable proteins, cold-turbid proteins and colloidal particles in beer, it effectively reduces beer turbidity, improves the transparency and luster of the wine body, making the wine body clear and bright; Second, beer stability improvement. Aiming at the non-biological turbidity problem that is prone to occur during beer storage, the product can specifically adsorb polyphenol-protein complexes, extending the beer shelf life to 6-12 months. It is especially suitable for craft beer, draft beer and other categories with high stability requirements. 2. Specific Usage Methods The recommended dosage is 0.1-0.5g/L (adjusted according to the turbidity of the beer wort). When using, first dilute the product with 5-10 times sterile water or beer wort, stir evenly and add it to the beer system. Stir at room temperature for 15-20 minutes, let it stand for 30 minutes, and then perform conventional filtration. The product is suitable for continuous production lines of large breweries and batch production of small craft breweries. The addition method can be adjusted according to the production scale, and it supports the adaptation of automatic feeding equipment. 3. Applicable Beer Types It can be widely used in the production of various beers such as pale beer, dark beer, stout, wheat beer, lager and ale. Especially in the quality improvement of craft beer, it performs outstandingly, which can effectively retain the unique flavor of craft beer while improving clarity. 3. Precautions - Storage Requirements: The product should be stored in a dry, ventilated and cool warehouse, avoiding direct sunlight and humid environment. After opening the package, it should be sealed and stored to prevent moisture absorption and caking. The recommended storage temperature is 5-35℃, and the shelf life is 24 months. - Usage Specifications: Strictly use according to the recommended dosage. Excessive addition may cause the beer taste to be slightly astringent; it is recommended to wear a dust mask during operation to avoid inhaling dust. If it accidentally gets into the eyes, rinse immediately with plenty of water. - Safety Tips: This product is a food-grade auxiliary material and is not edible. It is only used for process treatment in the beer brewing process; the product should not be stored or transported with toxic, harmful or odorous substances. - Transportation Points: Handle with care during transportation to prevent package damage. At the same time, avoid rain, sun exposure and severe vibration, and comply with relevant specifications for food-grade goods transportation. 4.
