Embodiment Construction

[0008] Specific embodiments of the present invention are:

[0009] a. Apple raw material quality control

[0010] Select a single variety of apples for processing, remove all moldy and rotten apples, control the apples with a mechanical damage area greater than 2% within 1%, and control the soluble solids of apple raw materials between 12% and 15%;

[0011] b. to clean

[0012] The first is water conveying and cleaning. The apples are washed from the fruit trough to the fruit washing trough with clean water, and then the secondary cleaning is carried out after lifting to remove the dust, microorganisms and other impurities attached to the surface of the apples, and then fully sprayed with soft water. ;

[0013] c. Cold crushing

[0014] The cleaned apples are directly sent to the cold crusher for crushing and separation. The cold crusher can choose the cold crusher of SIG MANZINI company in Italy or the cold crusher of BERTOCCHI company in Italy. The apples can be crushed i...

Abstract

The invention discloses an advanced process for producing the condensed apple thick juice, which can realize the industrialized production of high-quality condensed apple thick juice. In the present international markets, the supply of the condensed apple clear juice is far beyond demand, and the high-quality condensed apple thick juice is more and more popular in the markets, but because the effective process of producing the condensed apple thick juice is absent at present, the healthy development of the apple industry is seriously obstructed. The technical proposal of the process adopts the following steps: quality control of apple material; washing; cold crushing; inactive enzyme treatment; juice extraction; rough filtration; homogenization; deaeration; low-temperature condensation; sterilization by impulse electric field; and sterile filling. The condensed apple thick juice produced by the process has the advantages of little loss of nutrition, high stability and good taste, and key technical indexes are all higher than or meet those regulated in the trade standard QB2657-2004 of the condensed apple thick juice.

Description

technical field [0001] The invention relates to a production process of apple juice, in particular to a production process of concentrated cloudy apple juice, belonging to the technical field of food deep processing. Background technique [0002] Concentrated apple juice is divided into two types: concentrated apple juice and concentrated apple juice. The clear juice does not contain insoluble solids, while the cloudy juice contains insoluble solids because it has not been treated by enzymatic hydrolysis and ultrafiltration. At present, the concentrated apple juice on the market is mainly clear juice, with less turbid juice. The reason is that the production and processing technology of concentrated apple turbid juice is complicated, especially the technical problems such as browning and precipitation are difficult to solve. However, the pectin, protein, cellulose compound pigments, aromatic substances and vitamins contained in apple juice are far greater than those in clear...
