Embodiment 1

[0030]A kind of preparation method of citrus whole fruit superfine powder of the present invention, technological process is as figure 1 shown, including the following steps:

[0031] (1) Raw material pretreatment: select bright red sweet oranges that are fresh, rich in aroma and high in sugar content, remove rotten oranges, remove citrus stalks, clean soil and other impurities.

[0032] (2) Degradation and sterilization of pesticide residues: Put the pretreated citrus in an ozone tank for high-concentration ozone cleaning, the ozone concentration is 5mg / L-15mg / L, and the treatment time is 15min-40min to remove pesticide residues from citrus peels. Degradation and sterilization.

[0033] (3) Pulp micronization: transport the citrus degraded and sterilized by pesticide residues into the GFM-FC-3 fruit and vegetable crusher for crushing twice for coarse crushing at a speed of 1500r / min to obtain a mixture of citrus juice residue, citrus juice residue The particle size of the p...

Embodiment 2

[0041] A kind of preparation method of citrus whole fruit superfine powder of the present invention, technological process is as figure 1 shown, including the following steps:

[0042] (1) Pretreatment of raw materials: select fresh Century Red Tangerines, and remove rotten raw materials and soil and other impurities.

[0043] (2) Degradation and sterilization of pesticide residues: Put the pretreated citrus in an ozone pool for high-concentration ozone cleaning to degrade and sterilize the citrus peels with pesticide residues.

Abstract

The invention discloses a method for preparing tangerine whole-fruit superfine powder and the tangerine whole-fruit superfine powder. The preparation method comprises the following steps: performing ozone washing treatment on tangerines; and sequentially performing coarse grinding, wet-processing superfine grinding, ultrasonic grinding, enzymolysis, colloid grinding and high-pressure homogenizingto obtain whole-fruit pulp having the grain size of 5-15mu m; and performing vacuum freezing and spray drying on the whole-fruit pulp to obtain the whole-fruit superfine powder. According to the preparation method, the problem that fibers, pectin and other macromolecules in peels and seeds of tangerine whole fruits are water insoluble can be effectively solved, complete utilization of tangerines can be realized, and nutritional ingredients can be furthest maintained; the stability of the superfine powder under a juice system can be realized by utilizing the pectin of tangerines; the effects ofoxidation resistance, inflammation resistance and the like can be enhanced due to functional ingredients including flavone, limonin, carotenoid and the like; and the tangerine whole-fruit superfine powder has rich fragrance, bright color, rich functional nutritional ingredients and good stability.

Description

technical field [0001] The invention relates to the field of food technology, in particular to a preparation method of citrus whole fruit superfine powder and citrus whole fruit superfine powder. 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. In 2014, my country's planting area reached 2.42 million hectares, and the output was 34.9422 million tons, accounting for about 22.4% of the world's total output. The citrus industry involves more than 100 citrus counties in 19 provinces (cities, districts) across the country, involving a rural population of 182 million. [0003] Traditional citrus fruit powder is a powder obtained directly from citrus by pressing, and then spr...
