Abstract

The invention discloses a process for producing concentrated Chinese wolfberry clear juice, which comprises the following steps of: crushing ripe Chinese wolfberries, juicing the crushed Chinese wolfberries, removing seeds from the obtained juice, adding water and fully stirring to obtain primary cloudy juice; heating the primary cloudy juice, cooling the primary cloudy juice to the temperature of between 50 and 55 DEG C, adding amylase, pectinase and pear juice enzyme for digestion by maintaining the temperature of between 50 and 55 DEG C to obtain secondary cloudy juice; centrifugally separating supernatant fluid of the secondary cloudy juice to obtain Chinese wolfberry clear juice; and filtering the Chinese wolfberry clear juice by using a filtration membrane till the juice becomes clear, and performing vacuum concentration to obtain the concentrated Chinese wolfberry clear juice. The process for producing the concentrated Chinese wolfberry clear juice has the advantages that: conditions adopted in the process are mild, pectin and starch which influence the clear juice are removed by combining ordered heating and cooling with enzymolysis, and the nutritional ingredients in the Chinese wolfberries and the color and flavor of the juice are preserved to the utmost through the conditions of the whole process.
