Plant-based protein beverage

Plant-based protein beverages are milky liquid drinks made from plant nuts, fruit pulp, and other plant-based ingredients processed through specific techniques. These products are rich in plant proteins and a variety of nutrients, offering nutritional and health-promoting benefits.

Tea beverage

Tea beverages are drinks made through specific processing techniques, with the core ingredients being extracts obtained by water extraction from tea leaves, ground tea powder, or concentrated liquids produced via concentration processes.

Coffee beverage

Coffee beverages are carefully crafted drinks made from coffee beans that have been meticulously roasted and finely ground.

Sterilization Characteristics of Plant-Based Protein Beverages

1. Effective microbial control:
Because plant-based protein beverages are rich in a variety of nutrients, effective microbial control—especially against molds—is particularly critical during the production process. It is of paramount importance to explore and implement scientific and efficient mold-inhibition strategies without compromising taste, color, or pH, as this ensures both product quality and safety.
2. Technical Challenges:

Microorganisms such as yeast and mold may be introduced during the beverage packaging process. According to data analysis, 90% of sedimentation or flocculation issues are caused by excessive microbial growth, primarily involving molds and yeasts. High-temperature environments can adversely affect the intrinsic structure and physical properties of plant-based beverages, thereby impacting their quality and taste. Therefore, manufacturers need to address how to control and mitigate the effects of high temperatures on beverage structure and physical properties while simultaneously ensuring effective sterilization.
3. Nutritional ingredients:
During the sterilization process, it is crucial to ensure the integrity and stability of essential nutrients. Therefore, the selection and implementation of the sterilization process are particularly critical.

Sterilization characteristics of tea beverages

1. Effects on phenolic compounds:
Traditional heat treatment methods can affect the phenolic content, composition, and antioxidant properties of tea leaves. Therefore, sterilization technologies and processes are crucial.
2. Maintain quality:

Tea beverages contain natural ingredients such as tea polyphenols and caffeine, which are prone to decomposition or inactivation at high temperatures. Therefore, sterilization must strictly control temperature and duration to effectively eliminate microorganisms while preserving flavor and nutritional value. The correct sterilization method can minimize nutrient loss and help maintain the tea beverage’s color, texture, and aroma. High-temperature sterilization can enhance the extraction efficiency of bioactive compounds and ensure their stability.

3. Targeted sterilization:

Focus on effectively eliminating common spoilage and pathogenic microorganisms in tea beverages, such as yeast, mold, and heat-resistant Bacillus species, to meet commercial sterility or microbial limit requirements and reduce the risk of spoilage at the source.

Sterilization characteristics of coffee beverages

1. Quality considerations:
After undergoing a rigorous high-temperature sterilization process that meets the safety and sterilization parameters specific to the food industry, coffee’s flavor is preserved more effectively, with significantly better results compared to other processing methods. Notably, the sensory characteristics of the sterilized coffee remain highly consistent with those of unprocessed coffee.
2. Odor and fragrance:

Aromatic compounds play a crucial role in coffee flavor; some of these compounds decrease or increase during the roasting process, but the extent of these changes remains within an acceptable range. The dynamic changes in these compounds do not affect the core flavor profile of coffee, thereby ensuring the consistency of the drinking experience.
3. Highly influenced by the characteristics of the raw materials:
The quality of the raw materials significantly influences the outcome; the freshness and quality of the raw materials are directly linked to how well the flavor is preserved after sterilization. Although coffee beverages subjected to sterilization may experience some changes in taste and nutritional content, this step is an essential measure to ensure product safety.

Sterilization Precautions for the Beverage Industry

Sterilization method:

For plant-based protein beverages, high-temperature short-time pasteurization is preferred to avoid protein denaturation. For tea and coffee beverages, where flavor preservation is crucial, either high-temperature pasteurization or high-temperature short-time pasteurization can be used. For heat-sensitive formulations, aseptic filling technology can be employed to minimize the loss of flavor compounds.

Microbial Risk:

Plant-based protein beverages are prone to contamination by heat-resistant spore-forming bacteria such as Bacillus cereus. Tea and coffee beverages, due to their sugar content and nutrient-rich substrates, are easily contaminated by molds and yeasts, making it crucial to focus on preventing cross-contamination caused by contaminants carried in raw materials and residual residues left on equipment.

Rapid cooling:

After sterilization, plant-protein beverages, tea beverages, and coffee beverages must be rapidly cooled in stages within 30 minutes. Plant-protein beverages should be cooled to below 10℃ to prevent protein denaturation; tea beverages should be cooled to below 25℃ to avoid browning; and coffee beverages should be cooled to below 20℃ to prevent layering. At the same time, it is important to avoid excessive temperature differences that could affect product quality.

Storage and Packaging Protection:

Plant-based protein beverages, tea beverages, and coffee beverages should be stored in a dry, well-ventilated environment at temperatures between 0°C and 25°C, avoiding direct sunlight as well as high temperatures and humidity. Packaging materials should be appropriately selected (such as PET bottles, glass bottles, or aluminum cans) to ensure airtight seals, preventing leakage and secondary contamination. During transportation and storage, handle products with care to avoid deformation of PET bottles, breakage of glass bottles, and corrosion of aluminum cans. Throughout the entire process, minimize vigorous shaking to prevent product layering.
