Process for preparing concentrated asparagus clear juice

Abstract

The invention belongs to the field of food processing, and particularly discloses a process for preparing concentrated asparagus clear juice. The process for preparing the concentrated asparagus clear juice is characterized in that: asparagus waste serving as a raw material is processed into the asparagus clear juice by crushing, enzyme inactivation, cooling, juicing, sterilization, enzymolysis, clarification, concentration, secondary clarification, kieselguhr filtration, hyper-filtration, post concentration, sterile filling and complete clarifying technology. The process clarifies asparagus and milkwort by adopting the clarifying and filtering technology of combining biological, physical and chemical methods, fully prevents the loss of nutritional value of the asparagus, ensures the safety of a product, particularly prevents the waste of the asparagus resource by using the asparagus waste as the raw material for clear juice production, avoids environmental pollution, and fully improves the utilization value of the asparagus.
