Embodiment 1

[0019] Example 1 The processing method of beer special fruit juice, comprises the following steps:

[0020] ⑴Raw material selection: Picked fresh beer fruit is matured for 15 days under natural conditions, and the beer fruit with no decay, dark brown color and soft tissue structure is selected as raw material.

[0021] ⑵Wash the Beiteguo fruit twice with clean water, and crush it with a cyclone fruit crusher to obtain particles smaller than 0.3×0.3×0.3cm.

[0022] (3) Put the crushed granules into an enzymatic hydrolysis tank, add 0.35 g / L compound enzyme, and enzymolyze at 45°C for 75 minutes, and adjust the pH value to 40.~4.5 with food-grade acid and alkali, and then Squeeze under a pressure of 20MPa to obtain pomace and juice.

[0023] Wherein: the composite enzyme refers to the mixture of pectinase and cellulase in a weight ratio of 2g:1g.

[0024] ⑷Add pectinase to the juice according to 0.2% of its mass, and the enzymolysis time is 90min under the condition of enz...

Abstract

The invention relates to a processing method of Piteguo juice. The method comprises the following steps of: (1) selecting raw materials: selecting Piteguo fruits which are not rotted, are black brown in color, and become soft in tissue structure as raw materials after the picked Piteguo are ripe under natural conditions for 15 days; (2) washing the Piteguo fruits with clean water twice, and crushing by adopting a cyclone-type fruit crusher, thereby obtaining particles smaller than 0.3*0.3*0.3cm; (3) putting the crushed particles into an enzymolysis tank, adding compound enzyme for enzymolysis, adjusting the pH value to be 4.0-4.5 by food-grade acid-base, and then squeezing, thereby obtaining fruit residues and juice liquids; and (4) adding pectinase into the juice liquids for enzymolysis, and adjusting the pH value to be 4.0-4.5 by food-grade acid-base, clarifying, and sterilizing by adopting UHT (ultra high temperature), thereby obtaining the Piteguo juice. The processing method of Piteguo juice provided by the invention is simple in technology, and can effectively improve the juice yield.

Description

technical field [0001] The invention relates to a processing method of fruit juice, in particular to a processing method of beer fruit juice. Background technique [0002] Bud fruit, formerly known as skin bag fruit (also known as "bud bread", sour pear, and skin fruit by local people), is a unique ancient tree species growing at the foot of Prince Edward Mountain. It has a planting history of more than 1,000 years and belongs to the Rosaceae apple subfamily. A local cultivar of the Xinjiang pear family, which is at the upper limit of the distribution of Pyrus plants. It has the characteristics of strong tree vigor, long tree age, no strict requirements on soil, dampness and cold tolerance, resistance to diseases and insect pests, and strong adaptability. [0003] Beer Te fruit tastes sweet and sour, warm in nature, rich in protein, reducing sugar, crude fiber, vitamins (C, B 1 , B 2 ), tannic acid, amino acids, potassium, calcium, iron and other mineral elements necessary...
