This application claims priority to Chinese Patent Application No. 201911020617.9 with a filing date of Oct. 25, 2019. The content of the aforementioned applications, including any intervening amendments thereto, are incorporated herein by reference.
The present invention belongs to the field of enzymes, and relates to an apple enzyme for efficient reconstruction of intestinal microecology and a processing technology.
Enzymes are living enzymes and are prepared by fermenting food materials such as one or more fruits and vegetables through various natural probiotics adhering on the surface of the raw material and are fermented products rich in various enzymes, pectin, cellulose, mineral microorganisms, etc. The apple enzymes are rich in proteins, calcium, phosphorus, iron, zinc, potassium, magnesium, sulfur, carotene, vitamin B1, vitamin B2, vitamin C, niacin, cellulose and other nutrients. Research found that the apple is not only rich in nutrients that are necessary to the brain such as sugar, vitamins and minerals, but more importantly, are rich in zinc, which is conducive to promoting the growth and development and to improving the intelligence and memory.
At present, due to the reasons such as drugs, diet, ages, abnormal intestinal motility, immunity dysfunction and the like, most people in China are prone to intestinal microecological disorders. The long-term and large-scale use of broad-spectrum antibiotics is a main cause of the imbalance of intestinal flora in human bodies. Based on a health preservation concept, the apple enzymes as an optimum intestinal flora regulator are increasingly valued, and the nutritional concept is continuously popularized. With rich nutrients, the apple enzymes activate the cell viability and bring about certain benefit to the human body. Therefore, a lot of successful people caring about the health in China begin to drink the apple enzymes. Due to the simplicity in processing, the apple enzymes are generally hand-made in a small-scale homemade manner. The selection and treatment of raw materials and the control of fermentation conditions directly affect the quality of the apple enzymes, so that on the premise of increasing the utilization rate of the raw materials, to improve the fermentation efficiency, the flora abundance and the activity of relevant enzymes is the focus of the production and processing of the apple enzymes.
By searching, the following patent documents related to the present application are discovered. The specific disclosure is as follows:
1. “A method for simultaneously preparing apple brandy and apple pulp enzyme powder by using fresh apple pomace” (invention patent No.: ZL201510852062.X, authorization date: Jan. 12, 2018): the invention discloses a method for simultaneously preparing apple brandy and apple pulp enzyme powder by cold crushing and pulping the apple pomace after the solid fermentation, removing peels and seeds and transferring into a dryer for distillation and drying after the separation. The invention has the advantages that the apple enzyme for efficient reconstruction of intestinal microecology is prepared while the apple brandy is prepared, and the processing technology of the pulp enzyme powder is simple in operation. The disadvantages of the patent: (1) in the drying and renaturation process of the enzyme powder, the vitality of most probiotics and the activity of the enzymes may be reduced; (2) the enzyme powder prepared from the apple pomace is poor in taste, low in probiotics abundance and low in content of other nutrients; and (3) the traditional conventional technology is used to perform the solid fermentation for the pomace, while the enzyme fermentation time in the prior art is at least 3 to 6 months, so that the quality of the enzymes cannot be guaranteed.
2. “Composite fruit and vegetable enzymes and preparation method thereof” (invention patent No.: ZL201510617355.X, authorization date: Sep. 22, 2017): various fruits and vegetables are mixed and crushed and fermented by adding bacterial fluid and enzyme activity maintaining agent to prepare the composite fruit and vegetable enzymes. The invention has the advantages: the composite fruit and vegetable enzymes obtained by fermentation are complete in various enzymes and high in vitality. The disadvantages of the patent: (1) the composite fruits and vegetables are fermented collectively by Aspergillus oryzae, saccharomycetes and Bacillus subtilis, which are quite different in optimum fermentation conditions and have certain reciprocal inhibition effect, so that the fermentation efficiency and the bacterial strain abundance are relatively low; (2) by virtue of long-term standing fermentation, the deposition of raw materials and bacterial strains occurs, which is not conducive to the subsequent fermentation; and (3) the production period is relatively long, and the fermentation time is 500 to 1500 days.
3. “A preparation method of apple enzymes” (invention application No.: ZL201810979256.X, application date: Aug. 27, 2018): the raw material adopts core-removed sliced apples and is subjected to enzymolysis, yeast fermentation and acetic bacteria post fermentation to prepare the apple enzymes, which have the advantage that each bacterial strain can grow sufficiently according to the technological requirements, improves the fermentation efficiency and is high in nutritional value of fermentation metabolites. The disadvantages of the patent: (1) the core-removed apple slices are required as the raw material, so that the pretreatment requirement of the raw material is high, young fruits or defective fruits can be used, but there is the safety problem that patulin cannot be removed; (2) the applied bacterial strains are high in selection specificity for substrates and is poor in fermentation effect for the apple as the substrate; and (3) the activity of the enzymes and the abundance of the bacterial strain in a fermentation finished product are relatively low.
By summarizing the above patents, it is discovered that the existing apple enzyme processing technology has the following problems:
1. Low fermentation efficiency and long time: the fermentation time of the enzymes with low and medium quality by the traditional technology is about 1 to 3 months; the fermentation time of the high-quality enzymes is six months to more than one year, which is mainly because the specificity and an optimum growth condition regulation method of the applied bacterial strains as well as long-term standing fermentation and the deposition of the bacterial strains and the substrate are not conducive to the decomposition of the large-molecular substances, so that the fermentation efficiency is low.
2. Low probiotics abundance and low activity of relevant enzymes in the finished product are related to the quantity of the natural bacterial strains of the apple and the artificial bacterial strains participating in the fermentation; and additionally, a majority of probiotics and enzymes are extremely sensitive to the external unfavorable environment and are easy to die or inactivate.
3. The requirement on the raw material is high, and the use of young fruits and defective fruits for fermentation has the potential safety hazard of the patulin: in order to improve the product taste and safety, the core-removed apple slices are generally used as the raw material in the traditional technology, and the post-floral fallen fruits and artificially-thinned young fruits of the apple can also be fermented to obtain the enzymes with the same value by fermentation, but have the potential hazard of patulin.
4. Most apple enzymes are broad-spectrum preparations and are poor in specificity for intestinal microecological disorders caused by different factors: common causes and symptoms of the intestinal microecological disorders are as follows: for the microecological disorders caused by antibiotics, cocci substitute bacilli to become a dominant bacterial community; the high-fat diet is likely to cause the decrease of the number of intestinal Lactobacillus flora and bifidobacteria flora; the psychological stress and physical stress may also reduce the number of intestinal Lactobacillus flora and bifidobacteria flora; and the number of intestinal total anaerobe, lactobacilli and bifidobacteria of old people is reduced.
The purpose of the present invention is to provide an apple enzyme processing technology for rapidly and efficiently reconstructing an intestinal microecology of the human body and to solve the technical difficulties during the processing such as low fermentation efficiency and long fermentation time of young fruits and defective fruits, high content of patulin and low probiotics abundance and enzyme activity, etc.

The present invention has the advantages and beneficial effects:
1. In the present invention, the substrate is subjected to the division decompression dynamic intensified fermentation. First, pectinase and cellulase are added into the substrate to perform the constant-temperature decompression enzymolysis. Then the enzymolysis substrate is divided into multiple portions, and probiotics such as Aspergillus oryzae, Lactobacillus, Bifidobacterium, saccharomycetes and the like are added respectively into the portions to perform the separate decompression fermentation under the optimum conditions. During the fermentation process, the nitrogen is regularly introduced for a short time to disturb the fermentation broth so as to exchange upper and lower layers of fermentation broth, and then the pressure is returned. Finally, the fermentation products are mixed and blended. The optimum target substrates corresponding to the bacterial strains are added into the fermentation broths in the fermentation process, for example, starch and proteins are added into the Aspergillus oryzae fermentation broth, lactose is added into the Lactobacillus fermentation broth, and oligosaccharides such as fructose and galactose are added into the Bifidobacterium fermentation broth. The decompression purpose is to improve the inter-solute contact diffusion and permeation rate, to improve the fermentation efficiency and to shorten the fermentation time.
2. In order to reduce the use standard of the raw materials and increase the utilization rate of the raw materials, the present invention uses the post-floral fallen fruits and artificially-thinned young fruits of the apples to process the apple enzymes. The pulp of the apple is biologically degraded by plant Lactobacillus. A degradation product is repeatedly filtered and absorbed by the carboxylated nano multiwall carbon and neutral aluminum oxide filter screen for multiple times, thereby efficiently removing the patulin in the pulp, and eliminating the safety potential hazard.
3. In the present invention, according to the symptoms of different intestinal microecological disorders, the number of the corresponding bacterial strains is intensified. For the intestinal microecological disorders caused by antibiotics, the number of probiotic bacillus, Lactobacillus and bifidobacteria is intensified. For the microecological disorders caused by the high-fat diet and psychological stress as well as physical stress, the number of Lactobacillus and Bifidobacterium is intensified. For the gastrointestinal microecological disorders of the old people, the number of Clostridium butyricum, Lactobacillus acidophilus and Bifidobacterium is intensified. By specifically intensifying the number of different probiotic flora, the apple enzymes are more suitable for different people to eat, thereby implementing the efficient reconstruction of the intestinal microecology.
4. According to the present invention, the bacterial strains are subjected to the intermittent temperature change and oxygen supply and oxygen-deficient exercise to improve the adversity stress resistance of the probiotics. At the same time, the agent is added to maintain the vitality of the generated enzymes and original enzymes in the fermentation broth. The intermittent temperature change is mainly to regularly change the optimum fermentation culture temperature for a short time in the fermentation process, so that the bacterial strains can continuously break through the upper limit and lower limit of the adaptive temperature. At the same time, the anaerobic probiotics are subjected to the intermittent oxygen supply exercise; the aerobic and intermittent anaerobic probiotics are subjected to the oxygen-deficient exercise, so as to improve the strength of the bacterial strains, and improve the probiotics abundance of the finished product. By adding the agent, the high activity of relevant enzymes can be further maintained.
5. For the problems of the apple enzymes such as low fermentation efficiency and long time, the division decompression dynamic intensified fermentation method of the substrate is used, so that the high-speed and high-efficient fermentation of the apple can be realized, and the fermentation time can be greatly shortened. After the raw materials are pulped, the substrate is subjected to the decompression enzymolysis and fermentation and is divided into multiple portions, and the probiotics are added into the portions for separate fermentation under the optimum condition. At the same time, the optimum substrates such as the starch, proteins, lactose and the like are added into the fermentation broths, and the nitrogen is regularly introduced for a short time to disturb the fermentation broth, and the fermentation environment is appropriately kept at the low pressure to accelerate the inter-solute diffusion and permeation rate, thereby implementing the dynamic intensified fermentation. Finally, the separate fermentation broths are blended and mixed to rapidly obtain the high-quality apple enzymes.
6. For the problem that the enzyme finished product is low in probiotics abundance and activity of relevant enzymes, besides the addition of varieties of the fermentation probiotics, the intermittent temperature change and oxygen supply and oxygen-deficient exercise method is used to improve the adversity stress resistance of the probiotics and to increase the survival rate. At the same time, by adding the agent, the high activity of the probiotics-generating enzymes and original enzymes can be improved and maintained.
7. For the safety potential hazard of the presence of patulin caused by using the young fruits and the defective fruits, the pulp is biologically detoxified by plant Lactobacillus and repeatedly filtered and absorbed for multiple times by the carboxylated nano multiwall carbon and neutral aluminum oxide filter screen, so that the patulin can be efficiently removed, and the toxin residue is far less than the health standard (GB14974-1994) for limited quantity of the patulin in apple and hawthorn products in China.
8. Symptoms and treatment methods of the intestinal microecological disorders caused by different factors are different. The apple enzymes are broad-spectrum preparations and do not have the specificity. For this problem, the method for precisely intensifying the probiotics for the target groups is used, so that the efficient reconstruction of the intestinal microecological disorders caused by the antibiotics, high-fat diet, psychological pressure and physiological stress, and advanced ages and the like can be realized.
