Embodiment 1

[0039] A kind of preparation method of citrus whole fruit juice of the present invention, process flow chart is as follows figure 1 As shown, it specifically includes the following steps:

[0040] (1) Raw material pretreatment: select bright red sweet oranges that are fresh, rich in aroma, and high in sugar content, and remove rotten raw materials and soil and other impurities;

[0041] (2) Degradation of pesticide residues: The pretreated citrus was subjected to ozone compound high-voltage pulse electric field treatment. The ozone treatment time was 30 minutes, the ozone concentration was 10mg / L, the pulse electric field strength was 3kV / cm, and the pulse width was 90μs.

[0042] (3) Fruit juice micronization: transport the citrus degraded by pesticide residues into the GFM-FC-3 fruit and vegetable crusher for crushing twice at a speed of 1500r / min. The citrus juice residue mixture was crushed 5 times with a QDGP-11 shearing ultrafine pulverizer at a speed of 8000r / min, and ...

Embodiment 2

[0050] A kind of preparation method of citrus whole fruit juice of the present invention, process flow chart is as follows figure 1 As shown, it specifically includes the following steps:

[0051] (1) Pretreatment of raw materials: select fresh Century Red Tangerines, and remove rotten raw materials and soil and other impurities;

[0052] (2) Degradation of pesticide residues: The pretreated citrus was subjected to ozone composite high-voltage pulse electric field treatment. The ozone treatment time was 40 minutes, the ozone concentration was 5mg / L, the pulse electric field strength was 3kV / cm, and the pulse width was 90μs.

[0053] (3) Juice micronization: transport the citrus degraded by pesticide residues into the GFM-FC-3 fruit and vegetable crusher for crushing 3 times at a speed of 1500r / min. The citrus juice residue mixture was pulverized four times with a QDGP-11 shearing ultrafine pulverizer at a speed of 9000r / min, and the particle size of the whole fruit juice afte...

Abstract

The invention discloses orange full-fruit juice and a processing method thereof. The processing method mainly comprises the following steps: carrying out ozone composite high-pressure pulse electric field treatment on pre-treated oranges to remove pesticide residues of orange peel; carrying out coarse pulverizing, wet-process superfine pulverizing and colloid mill treatment on the oranges after the pesticide residues are removed to obtain full-fruit juice; carrying out compound enzyme moderate enzymatic hydrolysis treatment on the full-fruit juice; and carrying out homogenization, degassing and sterilizing on the juice after enzymolysis. The entire oranges can be totally utilized, and the nutrient substances of the oranges are retained to a great extent; stability of a juice system is realized by pectin of materials, and chemical additives are reduced; and by functional ingredients such as essential oil and flavone and ultra-high-pressure synergistic interaction, effective bacteria inhibition of the juice is realized, the qualities such as the original nutrient ingredients, color and taste in the materials are retained well, and the obtained orange full-fruit juice is rich in fragrance, bright in color, rich in functional ingredients and good in stability.

Description

technical field [0001] The invention relates to the technical field of food, in particular to a preparation method of citrus whole fruit juice and citrus whole fruit juice. Background technique [0002] Citrus is the largest fruit in the world, and it is cultivated in 146 countries and regions in the world, mainly concentrated in China, Brazil, the United States and the countries along the Mediterranean Sea. my country is the world's largest citrus country, and its citrus planting area and output both rank first in the world.
