The invention relates to the technical field of fruit and vegetable powder processing, in particular to a process for processing fruit and vegetable powder rich in cellulose. Freeze concentration, spray freeze granulation, and freeze-dry the normal pressure air to obtain fruit and vegetable powder; dry the solid matter with hot air to obtain dried cellulose; mix the dried fruit and vegetable powder and cellulose to obtain cellulose-rich fruit and vegetable powder, and sterilize ,Package. According to the nutrient components and heat-sensitive characteristics of fruits and vegetables, the quality-based processing is carried out, and the heat-sensitive functional components are preserved to the maximum extent by the full low-temperature treatment process; the non-heat-sensitive components after drying and separation are dried and separated by thermal drying. Compared with conventional vacuum freeze-drying, The product quality is comparable to vacuum freeze drying, the drying time is shortened by 50%, and the system saves energy by more than 30%. |
