Production method of sea-buckthorn pure fruit juice primary pulp

Abstract

The invention relates to a production method of fruit juice primary pulp, and specifically provides a production method of sea-buckthorn pure fruit juice primary pulp which is high in juice yield, high in soluble solid content and high in nutrition content and has no tannin bitter. The production method comprises the following processing steps of: removing fruits: shearing and selecting sea-buckthorn with branches by manpower, then quickly freezing, and after the temperature of the center of the fruit reaches (-18) DEG C, removing fruits by a fruit remover; pre-treating: removing leaves by a winnower, removing crushed branches by using a rotary fish-scale-sieve sieving machine; cleaning by using a fruit cleaner and removing sand by using sand removing equipment; immersing for 1-3min in 0 DEG C dewatering ripening solution and then draining, and unfreezing in microwave unfreezing equipment; and finally spraying by clear water at 0-5 DEG C so as to finish secondary cleaning and draining; and juice processing: breaking and pulping the sea-buckthorn, separating juice by using a juice separator, filtering impurities by using a juice primary filter, carrying out solid-liquid separation by using a horizontal spiral separator and a disc-type separator, degassing, sterilizing and sterilely filling, so as to obtain the sea-buckthorn pure fruit juice primary pulp.

Description

technical field [0001] The invention relates to a production method of fruit juice puree, in particular to a production method of seabuckthorn pure fruit juice puree. Background technique [0002] The fruit of seabuckthorn is juicy, delicious, sweet and sour, and rich in nutrition. It can be eaten or made into a drink.

Problems solved by technology

[0004] However, in the existing processing method of fruit juice puree, seabuckthorn has a short fruit stalk, is not easy to fall off and has thorns in the plant, so the harvesting function cuts off the fruit together with the fruit branch, and then carries out subsequent processing and operation. Therefore, during the pressing process, the components in the branches will be mixed into the final juice puree, which will reduce the proportion of nutrients in the juice and increase other residual substances, which will have a negative impact on the juice puree. On the one hand, due to the overall processing method, the content of soluble solids in the obtained fruit juice puree is too low, less than 8% of the fruit juice puree, the loss of nutrients is serious, and the juice yield is low, which will produce a bitter taste of tannins. Only seabuckthorn The color of the fruit, without its own unique aroma and taste
