Embodiment 1

[0028] Processed with frozen prickly pear fruit.

[0029] 1. Process route: frozen prickly pear fruit --- low temperature cleaning --- low temperature crushing and juice extraction - membrane concentration - sealed refrigeration.

[0030] 2. Process description:

[0031] (1) Low temperature cleaning: Take out the frozen prickly pear fruit from the -18 degree freezer and put it into the 2-stage cleaning tank. While thawing, remove gravel, floating leaves and rotten fruits to obtain clean prickly pear fruits with a temperature of 5-10 degrees. The purpose of the 2-stage cleaning is that the first stage of water is the initial washing, which needs to be discharged; the second stage of water is the fine washing, which needs to be filtered and recycled and control the core temperature of the prickly pear fruit.

[0032] (2) Crushing and squeezing juice: Install the paddle-type beater above the feed inlet of the belt press, and the whole is sealed and insulated. Introduce carbon dioxide a...

Embodiment 2

[0035] Processed with fresh prickly pear fruit.

[0036] 1. Process route: fresh prickly pear fruit --- low temperature cleaning --- low temperature crushing and juice extraction (vacuum deoxygenation) - membrane concentration - sealed refrigeration.

[0037] 2. Process description:

[0038] (1) Low temperature cleaning: Fresh prickly pear fruit is poured into a 2-stage cleaning tank. Remove sand, floating leaves, and rotten fruits to obtain clean prickly pear fruits with a temperature of 20-25 degrees. The purpose of the 2-stage cleaning is that the first stage of water is the initial washing, which needs to be discharged; the second stage of water is the fine washing, which needs to be filtered and recycled and control the core temperature of the prickly pear fruit.

[0039] (2) Crushing and pressing: Install the paddle-type beater above the feed inlet of the belt press, and the whole is sealed and insulated. Introduce carbon dioxide at the bottom of the equipment, use the feed po...

Abstract

The invention discloses a processing method of protecting SOD of concentrated rosa roxburghii juice. The processing method comprises the following steps of refrigerating rosa roxburghii fruits, performing low-temperature cleaning, performing low-temperature oxygen-separation breaking and squeezing, performing reverse osmosis membrane concentration of pre-microfiltration, and performing sealing and cold storage, wherein the step of low-temperature oxygen-separation breaking and squeezing is used for leading inert gas to a breaking machine and a squeezing machine set for separating oxygen and maintaining positive pressure environment, so that the breaking and squeezing process is in a low-temperature oxygen-separation state; the step of reverse osmosis membrane concentration of pre-microfiltration is used for performing membrane concentration after compressed fruit juice is subjected to multi-level filtration (including microfiltration), wherein the concentration process is in the low-temperature oxygen-separation state. In an entire production course of the processing method, any foreign chemicals (free from pollution) are added, steam is not needed in the production course, and the electricity consumption is low; and drained waste water drained by cleaning fruits, and rosa roxburghii dry residues can be cycled in a green ecological manner. The processing method disclosed by the invention is an environmentally-friendly energy saving technique, and is particularly suitable for being used in Guizhou regions with good ecology and low temperature.

Description

Technical field [0001] The invention relates to a method for processing concentrated fruit juice, in particular to a crushing, pressing and concentration process. Background technique [0002] Cili contains very rich superoxide dismutase (SOD) (SOD activity reaches 5000U / g). Its health value is mainly natural superoxide dismutase (SOD), which is related to body aging, tumorigenesis, autoimmune diseases and radiation protection. At present, SOD activity has become an important indicator of anti-aging drugs and anti-aging health foods. [0003] However, it is easy to be destroyed in the following two situations: overheating, and the fruit is broken and decomposed in an aerobic environment. [0004] Conventional methods are currently used for processing prickly pear juice: washing, high temperature enzyme inactivation, normal temperature crushing, open juice extraction, high temperature sterilization, and high temperature concentration. This high temperature and open process almost c...
