Example Embodiment

[0018] Example 1. Preparation of cold fresh mango pulp

[0019] 1) Preparation: 1000g fresh mango diced meat, add 300g water and 400g fructose.

[0020] 2) Coarse pulp preparation: Use jm-fb split colloid mill for initial grinding to grind the mixture of diced fruits into coarse pulp, and the measured particle size is 20-40μm. Technical requirements: The temperature is controlled at 30°C during grinding.

[0021] 3) Fruit-soluble fiber: Use ATS-100b ultra-high-pressure homogenizer to homogenize the crude pulp and grind it at a working pressure of 60-80Mpa to obtain a finished pulp. The ultra-fine fiber of the pulp is soluble in water. Technical requirements: fruit soluble fiber nanometer level, homogeneous grinding temperature control at 15 ℃. The measured particle size is 200-800nm.

[0022] 4) Vacuum liquid sub-packaging: Use 400 type vacuum packaging machine to sub-pack according to a certain amount, and the sub-packing pressure is ≤1Kpa to prevent the pulp from oxidation. Techn...

Abstract

The present invention relates to a cold fresh pulp preparation method. The technical problem solved by the present invention is to reduce oxidation during a fresh keeping process, improve pulp freshness and improve original taste. A super micron fiber fruit dissolving technology is adopted, such that the pulp is instantly dissolved in water, layering and precipitation are not easily generated, and nutrition is easily absorbed by human body. The preparation method comprises the following steps: 1) preparing a material; 2) adopting a colloid mill to prepare a coarse pulp; 3) preparing fruit dissolving fibers, wherein the coarse pulp is grinded into fruit dissolving fibers through a super high pressure homogenizer, a particle size is less than or equal to 800 nm, super high pressure homogenizer working pressure is 60-80 Mpa, and a grinding temperature is controlled to less than or equal to 20 DEG C; 4) carrying out vacuum liquid state sub-packaging; 5) carrying out super high pressure low temperature sterilization; 6) carrying out low temperature quick partial-freezing, wherein the sterilized pulp is placed into a low temperature quick partial-freezing machine, a freezing temperature is -30 to -35 DEG C, and a freezing time is 6-15 min; and 7) carrying out low temperature cold preservation, wherein a temperature is less than or equal to -18 DEG C.

Description

technical field [0001] The invention relates to a fruit post-processing technology, in particular to a preparation method of cold fresh fruit pulp. Background technique [0002] Fresh melons, fruits and vegetables are rich in nutrition but cannot be preserved; some beans, tubers and nuts are nutritious but not easily absorbed by the body. For a long time, the preservation of dried and fresh fruits and vegetables has been based on the technology of high-temperature sterilization and low-temperature freezing. For example, Chinese patent document CN1846541 adopts a high-temperature enzymatic sterilization process in the process of preparing fruit pulp. The deep processing of dried and fresh fruits and vegetables is nothing more than making cans or squeezing juice to make pulp. The pulp preparation method using high-pressure homogeneous treatment represented by Chinese patent document CN1099949 is particularly effective in retaining nutrients and promoting human body absorption....
