How to make longan milk powder
This is a method of processing solid beverages. Yuan meat is a traditional and precious nutritious medicine and food homologue. It is suitable for old age, body failure, lack of blood and blood, postpartum blood loss, and mental decline. Therefore, it is also a health-type solid drink. Processing techniques are as follows: 1. Raw material treatment: The mature longan fruit is removed by shelling, the pulp is added into a pulper to make a fine slurry, and a small amount of water can be added during the pulping to facilitate the formation of a fine slurry, and then the slurry is separated by a centrifuge. Or use a bag filter to take its juice, and leave the fruit residue for comprehensive use. 2. Juice Concentration: Heating in a stainless steel pan or using a vacuum concentration method to evaporate most of the water in the thin juice, and the concentration of solids is close to about 20%. This will not only ensure nutrient content but also facilitate the granulation process. 3. Sweetener processing: The sugar used is one of the main raw materials of solid beverages, which needs to be dried and ground into powdered sugar with a dosage of 20-25%, and other additives such as citric acid 1-1.5%, appropriate amount of coloring material, proper amount of flavoring. . 4. Thoroughly mix the additive with concentrated juice and add 5-8% maltodextrin, a drying aid. After the above materials are fully mixed, the moisture content of the material is controlled at about 10%. 5. Granulation: A certain shape of particles is formed by a rocking granulator. 6. Drying: Strong hot air heating and drying, drying temperature 50-70 degrees Celsius, time 1-2 hours, the product moisture content of 2%, the drying process can be completed. 7. Packaging: Small bags are sealed and packaged. The finished product should be packaged in a room with a relative humidity of 20% and a temperature of 15-20 degrees Celsius. It should also be stored under conditions of low temperature and low humidity.
