Description

Production method of probiotic fermented hawthorn fruit roll
Technical Field
The invention relates to a production method of a hawthorn fruit roll by probiotic fermentation.
Background
Hawthorn (Crataegus pinnatifida Bunge) is a Crataegus plant of Rosaceae, is rich in nutrition, contains polyphenols, phenylpropanoids, flavonoids and other compounds with biological activity, and has the effects of resisting oxidation, resisting inflammation, reducing blood lipid and the like. The hawthorn haw sheet is a sugar fruit food which is prepared by taking hawthorn rich in pectin and organic acid as main raw materials and processing the hawthorn through sauce preparation, scraping, drying, forming and the like, and the appearance shape of the sugar fruit food is a flaky, flaky and strip-shaped roll shape. The hawthorn preserved fruit food represented by the hawthorn roll is the key point of hawthorn processing products and is deeply popular with consumers. Because the content of organic acids such as malic acid, citric acid, succinic acid and the like in the hawthorn is too high, a large amount of sucrose is required to be added to adjust the flavor of the traditional hawthorn fruit roll, so that the hawthorn fruit roll has the characteristic of high sugar. Diets characterized by high-sugar foods are considered to be the main reason for the rapid increase of metabolic diseases such as obesity and diabetes in recent years, so that the consumption of high-sugar foods including sweetmeats is severely limited, and the sustainable development of the industry is not facilitated. In addition, the hawthorn fruit roll prepared by using the functional oligosaccharide and the sugar alcohol to replace cane sugar can reduce the sugar content in the hawthorn fruit roll, but has single nutrition and flavor. In addition, after the probiotic fermentation, the nutrition and functional components of the raw materials are retained, and the health-care function of the probiotic is endowed, so that the product has both the raw material flavor and the fermentation flavor.
The metabolism of organic acid, some special enzyme systems and lactic acid generated in the probiotic fermentation process in vivo can improve the blood fat of human body and delay the aging of human body; the produced extracellular polysaccharide has the functional characteristics of antioxidation, anticancer, immunoregulation, antibiosis, blood sugar reduction, blood pressure reduction, cholesterol reduction and the like, so the probiotics is widely applied to the food fermentation industry. At present, main probiotic fermentation strains applied to food comprise lactic acid bacteria, bifidobacteria, microzyme, probiotic bacillus, clostridium butyricum and the like, and are not only applied to the fermentation of fruit and vegetable juice which takes grapes, apples, carrots, tomatoes, litchis, blueberries and the like as raw materials, but also applied to the fermentation of jam. Researchers find that the lactobacillus can be used for fermenting and preparing preserved fruit products, for example, the lactobacillus is used for fermenting and deacidifying green plum fruits to prepare low-acidity green plum preserved fruits.
At present, a lot of deep-processed products of hawthorns exist in the market, and products related to probiotic fermentation are mainly concentrated on beverages and yoghourt. Until now, products of preserved fruits prepared by fermenting hawthorn with probiotics are not available.

Second, parameter detection
1. Sensory evaluation
Inviting 10 sensory evaluators to perform sensory evaluation on the lactobacillus fermented hawthorn fruit roll, wherein the evaluation standard is as follows: influence of Limo, Liu Fang, Warm, et al, iron-rich fermented soybean powder on quality of cortex moutan [ J ]. food industry 2015(11) 147-. The total score is 100, the color is 30, the taste is 30, the mouth feel is 20 and the texture is 20. The results are shown in table 1, and the lactobacillus fermented hawthorn sheets have no significant difference (P >0.05) in color, texture, taste and total components compared with the traditional hawthorn sheets (the sucrose hawthorn sheets prepared without lactobacillus fermentation, which are prepared in the same step but without probiotics) in the preparation method.

Figure BDA0002277030570000051
Note: in the same column, data labeled with different letters indicate significant differences (P <0.05), and significance analysis of data between groups was performed using duncan (d) multiple comparisons in One-dimensional analysis of variance (One-wayaanova).
2. Apparent form
The color and the transparency of the sweetend roll can be judged by observing the apparent form of the sweetend roll.
The apparent morphology of the lactobacillus fermented hawthorn peel roll prepared according to the process of example 1 is shown in figure 1. Fig. 1A shows the dried product, and fig. 1B shows the packaged product. The result shows that the lactobacillus fermented hawthorn fruit roll has bright red color and high transparency, and the color and the transparency of the lactobacillus fermented hawthorn fruit roll are closer to those of the traditional hawthorn fruit roll.
3. Texture structure
The texture parameters of the lactobacillus fermented hawthorn fruit peel roll are collected by a texture analyzer (the method is referred to as: extra sea, shouxinju, shorea, et al. response surface test optimization ultrasonic sugar infiltration preparation process of wild actinidia arguta preserved fruit and texture analysis thereof [ J ]. food science, 2015,36(20):49-55.), and the results are shown in table 2. Among the texture characteristics, hardness is an important index for measuring the quality of the sweetend roll. As can be seen from Table 2, the lactobacillus fermentation has a significant effect on the hardness of the hawthorn sheets, and the fermentation reduces the hardness of the hawthorn sheets. It can be seen from the table that the lactobacillus fermentation has no significant effect on the cohesiveness and elasticity of the hawthorn sweetened roll (P > 0.05). The adhesiveness is the negative peak area formed by the stress and time of the probe, and reflects the adhesiveness of the fruit peel. Exopolysaccharide is a polymer with high molecular mass, produced by the metabolism of probiotics, which forms a colloid after dissolving in water, increasing the viscosity of the fermentation product. Therefore, compared with the traditional hawthorn fruit roll, the viscosity of the hawthorn fruit roll prepared after lactobacillus fermentation is obviously increased (P is less than 0.05). Chewiness is generally a combination of hardness, cohesiveness, and elasticity of solid food, the size of which represents the energy required to chew the solid food into a state capable of being swallowed. As can be seen from Table 2, the chewiness of the hawthorn fruit roll prepared by lactobacillus fermentation is not significantly different from that of the traditional hawthorn fruit roll (P is more than 0.05). In conclusion, the quality and structure characteristics of the hawthorn fruit roll fermented by the lactobacillus are similar to those of the traditional hawthorn fruit roll.

Note: data are presented as mean ± standard deviation (n ═ 3); in the same column of shoulder letters, the same means that the difference is not significant (P >0.05), and the different means that the difference is significant (P < 0.05).
4. Color difference
Color difference data of lactobacillus fermented hawthorn peel roll are collected by a color difference meter (method reference: the effect of livinghao, shenqun, jiayukun, et al, temperature illumination on the color of the haw sheet [ J ] processing of agricultural products (schoolwork), 2009(5):22-23 ], and the results are shown in table 3. In the aspect of L value, compared with the traditional hawthorn fruit roll, the hawthorn fruit roll prepared by lactobacillus fermentation has no significant difference (P is more than 0.05). In the aspect of the values of a and b, compared with the traditional hawthorn sheets, the hawthorn sheets prepared by the lactobacillus fermentation all change the sizes. Δ E characterizes the difference in color, which is fitted by L/a/b. Compared with the traditional hawthorn fruit sheets, the delta E of the hawthorn fruit sheets prepared by lactobacillus fermentation is obviously increased (P is less than 0.05). In conclusion, the hawthorn fruit roll prepared by lactobacillus fermentation is closer to the traditional hawthorn fruit roll in color and luster characteristics.

Note: data are presented as mean ± standard deviation (n ═ 3); in the same column of shoulder letters, the same means that the difference is not significant (P >0.05), and the different means that the difference is significant (P < 0.05).
5. Physical and chemical properties
The results of the measurement according to the physicochemical indexes (moisture, ash content and total sugar) of the preserved hawthorn products specified in GB/T31318-; ash content (%) is less than or equal to 1.5; the total sugar content (calculated by glucose) is less than or equal to 75.0 percent. In the intestine, sucrose is degraded by α -glucosidase into glucose and fructose, which, upon absorption by the intestine, results in elevated blood glucose levels. Lactic acid bacteria utilize sucrose, glucose and other fermentation to produce metabolites such as lactic acid, and reduce the content of reducing sugar. The result shows that the total sugar content of the hawthorn sweetened roll prepared by lactobacillus fermentation is remarkably reduced (P is less than 0.05), and the reduction amount is 15.4%.

Note: and x represents no detection.
7. Organic acid content
Organic acids such as short-chain fatty acids (acetic acid, propionic acid, butyric acid, etc.) and lactic acid can lower the pH of the environment in the intestinal tract and inhibit the proliferation of harmful bacteria, thereby maintaining the balance of intestinal microecology. The fermentation and nutrition function conditions of the hawthorn roll are shown by measuring the content of organic acid in the hawthorn roll fermented by lactic acid bacteria, and the results are shown in table 6. The traditional hawthorn fruit leather does not contain lactic acid and butyric acid, and the contents of lactic acid, acetic acid and propionic acid in the hawthorn fruit leather are respectively increased by 28.0%, 76.8% and 51.7% compared with the traditional hawthorn fruit leather after being fermented by lactic acid bacteria.
The specific detection method comprises the following steps: weighing 0.2g of hawthorn tree peony bark, adding into 0.8mL of distilled water, homogenizing, centrifuging at 12000rpm for 10min, and collecting supernatant. Adding 100 μ L concentrated hydrochloric acid into the supernatant, adding 5mL diethyl ether, mixing, extracting at room temperature for 20min, and centrifuging at 3500rpm for 10 min. Transferring the upper organic phase into another tube, adding 500 μ L of 1M NaOH solution, mixing well, extracting at room temperature for 20min, and centrifuging at 3500rpm for 10 min. Collecting lower water phase, adding 100 μ L concentrated hydrochloric acid, mixing, filtering the obtained extractive solution with 0.22 μm water system filter membrane, and performing High Performance Liquid Chromatography (HPLC). The detection conditions were as follows: the liquid chromatographic column was a hydrogen ion exchange column (Agilent Hi-Plex H250, 300X 6.5 mm).
