Description

Preparation method of noni enzyme juice and noni enzyme juice
Technical Field
The invention relates to the technical field of food, and in particular relates to a preparation method of noni enzyme juice and the noni enzyme juice.
Background
Noni is also known as morinda citrifolia, and belongs to the family of rubiaceae. Noni fruit grows mainly in the south pacific isles, and varieties are found in other tropical regions of the world. Has been used for more than 2000 in poliisia for staining of food, medicine and traditional clothing, its medical use is believed to include improvement of diabetes, gout, hypertension, cancer, boils and other skin and internal diseases; modern scientific researches show that the fruits and leaves of noni fruits are rich in a large amount of substances beneficial to human bodies, wherein the substances comprise five nutrients, eight essential amino acids for human bodies, multiple trace elements such as Zn, Ca and Na and functional components such as flavone, flavonoid glycoside, saponin, polysaccharide and the like, and the noni fruits have high medicinal value and edible value.
The noni fruits are usually sealed and fermented directly in the traditional noni enzyme preparation process, and the noni fruits can be rotted after being picked for 24 hours, so that the storage and transportation of the noni fruits are very challenging due to the characteristic, and when the rotted noni fruits are fermented, bacteria, saccharomycetes, acetic acid bacteria and other mixed bacteria can be fermented, so that bad smell is generated, and the taste and quality are influenced. In addition, the whole fruit is fermented for a long time in the traditional process, so that anthraquinone substances in the peel can be dissolved out, and excessive anthraquinone substances can cause harm to human bodies. Therefore, there is a need for a method for preparing noni ferment juice, which not only ensures the food safety of the juice, but also has better taste and smell.
Disclosure of Invention
In order to solve the problems, the invention provides a preparation method of noni enzyme fruit juice and the noni enzyme fruit juice, the juice yield is high, anthraquinone substances are reduced or even avoided dissolving out, and the fruit juice tastes good.
The invention provides a preparation method of noni ferment fruit juice, which comprises the following steps:
s1, cleaning noni fruits and then draining;
s2, adopting a quick-freezing mode to enable the central temperature of the noni fruits to reach-16 to-20 ℃; because the freshly picked noni fruits usually begin to rot after 24 hours, and the noni fruits naturally ferment and rot in the traditional fresh noni fruits during storage or long-time transportation, bacteria, saccharomycetes, acetic acid bacteria and other infectious microbes can ferment, so that bad smell can be generated, and the taste and the quality of juice can be influenced, the noni fruits which are cleaned and dried are quickly frozen and stored and transported at the low temperature of-16 ℃ to-20 ℃, the problem of fermentation of various infectious microbes is avoided in the low temperature environment, and the nutrient substances of the noni fruits are maximally preserved in the quick-frozen noni fruits. After the noni is quick-frozen, the liquid in the noni forms ice crystals to puncture cell walls, which is beneficial to improving the juice yield.
S3, unfreezing the quick-frozen noni under natural conditions until the central temperature of the noni reaches-3 ℃ to-5 ℃;
s4, squeezing the unfrozen noni to obtain noni juice;
s5, fermenting the noni juice in a closed environment to obtain noni enzyme juice.
Further, the noni fruit is a fully ripe noni fruit at step S1, and the skin of the noni fruit is intact.
Further, the cleaning method in step S1 includes: and (4) soaking the powder by using purified water, and washing away silt and dust on the surface.
Further, in the step S4, the squeezing pressure is less than 5Mpa, and the squeezing temperature range is-1 ℃ to-5 ℃; the national toxicology program study of the united states concluded that anthraquinones can cause kidney, liver and prostate cancer in rat mice. The European Union has limited amount of anthraquinone in food, such as 0.02mg/Kg for anthraquinone in tea. The noni fruit peel contains anthraquinone substances, and in the traditional process, the whole fruit is fermented in a closed container for half a year, 3 years or even longer, so that the anthraquinone substances in the peel are dissolved out after long-time fermentation. The invention adopts non-crushing whole fruit low-temperature direct pressing, avoids anthraquinone substances in fruit peel from dissolving out caused by crushing and soaking fruit peel, so that the low-temperature non-crushing whole fruit pressing adopted in the noni fruit juice processing can avoid and reduce the dissolving out of the anthraquinone substances. In addition, the whole fruit is not crushed, the low temperature direct squeezing is adopted, so that the contact between the fruit juice and air is reduced, and the oxidation is reduced; the pressure selection in the fruit juice squeezing process has an important influence on the juice outlet effect of the fruit, if the squeezing pressure is too high, the seeds can be fractured, the content of the seeds can be dissolved out to influence the taste of the fruit juice, and if the squeezing pressure is too low, the juice outlet rate is influenced. The temperature is between-1 ℃ and-5 ℃ to avoid the dissolution of anthraquinone substances, and the invention can not only avoid the crushing of seeds but also improve the juice yield under the conditions of the temperature between-1 ℃ and-5 ℃ and the pressure range of 1-5 Mpa.
Further, the fermentation temperature range of the noni juice in the step S5 is 37-42 ℃, and the fermentation time is more than 6 months.
Further, when the fermentation time reaches 6 months, pouring the fermented noni juice supernatant into another fermentation tank for storage, wherein the storage temperature is in a range of 37-42 ℃, and the juice after pouring can be filled.
The invention provides noni enzyme fruit juice and a preparation method thereof.
As described above, the present invention has the following advantages compared with the prior art:
1. the method has the advantages that the cleaned noni fruits are quickly frozen, so that the noni fruits are prevented from being directly exposed in the air to cause the fermentation of bacteria, saccharomycetes, acetic acid bacteria and other infectious bacteria to generate bad smell, the frozen noni fruits can be stored and transported for a long time, and the problem of short preservation time of the fresh noni fruits is solved; the morinda citrifolia processed by quick freezing can maximally preserve the nutritional value and taste of the morinda citrifolia, and under the quick freezing condition, water in the morinda citrifolia is converted into ice crystals to destroy cell walls, so that the juice yield is improved.
2. The invention adopts a low-temperature squeezing mode without crushing the whole fruit, reduces and even can avoid the dissolution of anthraquinone substances in the peel caused by crushing and soaking the peel, and ensures the food safety of the fruit juice.
3. The invention adopts a low-temperature and low-pressure squeezing mode to squeeze the juice, anthraquinone substances are prevented from dissolving out under the low-temperature condition, the squeezing pressure less than 5Mpa can prevent the noni seeds from cracking, and the optimal taste of the noni is ensured while the juice yield of the noni juice is ensured.
