Plant protein beverage is a nutritional beverage made from plants rich in edible protein such as peanuts, walnuts, almonds, soybeans, etc., through baking, grinding, separation, homogenization, UHT sterilization, and aseptic filling. Its protein content is ≥ 0.5%, containing unsaturated fatty acids, dietary fiber, and trace elements such as calcium and selenium. It has zero lactose and cholesterol, making it suitable for people with lactose intolerance and three highs. The production line integrates water treatment, colloid mill, centrifugal separation, 20-60 MPa high-pressure homogenization, 137 ℃/4 s UHT, PET sterile filling and CIP system, and can produce nut milk, seed milk, composite milk, plant yogurt, etc., with a production capacity of 2000-36000 bottles/hour. The product uses Tetra Pak bags PET、 Aluminum cans or glass bottles, stored at room temperature for 6-12 months, can be fortified with vitamin D and oligopeptides BCAA， Suitable for breakfast, fitness, silver hair, specialty medicine, and e-commerce scenarios.

2、 Terminal product matrix (protein content ≥ 0.5%)
|Type | Representative item | Selling point | Packaging form|
|Nut milk | Walnut milk, almond milk, peanut milk | Strong baking aroma, calcium content is twice that of milk | 250 mL Tetra Pak, 1 L PET|
|Seed milk | Sunflower seed milk, pine nut milk | Selenium rich, hypoallergenic | High end gift box in 200mL glass bottle|
|Soy milk | Soy milk, blended soy milk | Lactose free, zero cholesterol | 200-1000 mL sterile brick|

4、 2025 'Roll' Point Express Delivery
1. Baking aroma recovery: Online condensation baking exhaust gas, aroma backfilled into the beverage, walnut characteristic aroma increased by 40%.
2. Dual enzyme hydrolysis+membrane separation: neutral protease+cellulase, free amino acids increased by 20%, and the removal rate of bitter peptides after ultrafiltration was ≥ 70%.
3. Low sugar and high calcium formula: using calcium carbonate microcapsules+oligofructose, which not only lowers blood sugar but also improves calcium absorption rate, with clean labels.
4. Flexible packaging material: 38 mm large caliber aluminum can+transparent high barrier PET, meeting the "unscrewing and drinking" sports scene.
5. Digital twin: The entire line data is connected to Alibaba Cloud/Siemens MindSphere, reducing downtime by 30% for predictive maintenance.

5、 One sentence summary

Vegetable protein beverage has been upgraded from "breakfast supporting role" to "full scene nutrition solution"; Whoever masters the three-stage process of "baking and flavoring+double enzyme hydrolysis+sterile cold infusion" can create the "next generation plant-based milk" that consumers can pay for above the national standard red line of 0.5% protein content.
