In view of the defects of the prior art, the invention provides a cranberry candy and a preparation method thereof.
In order to realize the purpose, the invention provides a cranberry candy which comprises the following raw materials: cranberry powder, water shield extract, honeysuckle extract, aloe barbadensis extract, magnesium stearate and honey powder.
Preferably, the cranberry candy comprises the following raw materials in parts by weight: 70-85 parts of cranberry powder, 10-15 parts of water shield extract, 5-10 parts of honeysuckle extract, 15-20 parts of aloe barbadensis extract, 12-20 parts of magnesium stearate and 20-35 parts of honey powder.

The water shield has no taste, is superior to the round, delicious and smooth taste, and is one of the precious vegetables. The water shield is rich in carbohydrate, multiple vitamins and minerals, has health promotion effect of medicine and food, and has antibacterial and antiinflammatory effects on oral cavity and pharynx.
Honeysuckle (Lonicera japonica Thunb.) is the bud or first-bloomed flower of Lonicera japonica Thunb of Lonicera of Caprifoliaceae. The honeysuckle is rich in active ingredients such as volatile oil, flavonoid, triterpenes, organic acid and the like, and has the effects of bacteriostasis, antivirus, fever reduction, inflammation resistance, liver protection, oxidation resistance, immunoregulation and the like.
Aloe vera (Aloe barbadensis Miller), the Isaria islands and Babados islands native to the Islands of America, west India, is known in China as Aloe barbadensis. Aloe vera has the effects of inhibiting bacteria, resisting inflammation, enhancing organism immunity, invigorating stomach, relieving diarrhea, protecting liver, relieving pain, resisting cancer and virus, promoting wound healing, beautifying, resisting sunburn and the like, is clinically used for treating various inflammations, and has obvious curative effect.
Preferably, the preparation method of the cranberry powder comprises the following steps: freeze drying the frozen cranberry at the temperature of between 20 ℃ below zero and 18 ℃ below zero for 24 to 36 hours, and crushing to obtain cranberry powder.
The materials with antibacterial and antiinflammatory effects in cranberry are mainly polyphenols including flavonoids, anthocyanidin, procyanidin, etc. Polyphenols are compounds with high biological activity, are widely present in plant resources, are usually combined with sugar to form glycosides, a small part exists in the form of free aglycones, and the free aglycones have higher bioavailability. Therefore, deglycosylation directionally modifies the molecular structure of the polyphenol compound, efficiently releases aglycone, and is an important way for improving the specific function and bioavailability of polyphenol. At present, chemical methods such as etherification, esterification and acylation are mostly adopted for preparing polyphenol aglycone, but the reaction processes of the methods react with phenolic hydroxyl groups of polyphenol compounds, so that the oxidation resistance of products is reduced. In addition, the chemical method is complex, and the safety of the hydrolysate of the polyphenol compound is needed to be further researched.
Beta-glucosidase, also known as beta-D-glucoside hydrolase, also known as amygdalase, cellobiase, and gentiobiase, catalyzes primarily the beta-glycosidic bond at the non-reducing end of the flavonoid glycoside, disaccharide, oligosaccharide, aryl glucoside, and glycosyl glucoside. Due to the wide substrate specificity and the capability of hydrolyzing and synthesizing glycosidic bonds of the beta-glucosidase, the application of the beta-glucosidase is very wide. The invention utilizes beta-glucosidase to hydrolyze the cranberry, thereby not only being safe and efficient, but also improving the aglycone content in the cranberry, and further improving the antibacterial and anti-inflammatory capabilities of the cranberry.
Further preferably, the preparation method of the cranberry powder comprises the following steps:
s1, unfreezing frozen cranberries and pulping to obtain cranberry pulp;
s2, adding beta-glucosidase hydrolysate into the cranberry pulp obtained in the step S2, stirring at the rotating speed of 300-500 r/min at the temperature of 50-65 ℃, and reacting at constant temperature for 2-8 hours to obtain cranberry enzymatic hydrolysate; the preparation method of the beta-glucosidase hydrolysate comprises the following steps: 5-10 g of beta-glucosidase is added with acetic acid-sodium acetate buffer solution to fix the volume to 1-1.5L;
and S3, freezing, drying and crushing the cranberry enzymatic hydrolysate obtained in the step S2 to obtain cranberry powder.
However, in the process of hydrolyzing the cranberry by the beta-glucosidase, the inventor finds that the activity of the beta-glucosidase is gradually inhibited along with the accumulation of glucose which is one of hydrolysate, so that glycoside substances in the cranberry can not be completely hydrolyzed. In order to improve the sugar tolerance and the enzyme activity of the beta-glucosidase, the D-glucose-6-phosphate is added in the hydrolysis process, so that the sugar tolerance and the enzyme activity of the beta-glucosidase are improved.
More preferably, the preparation method of the cranberry powder comprises the following steps:
s1, unfreezing frozen cranberries and pulping to obtain cranberry pulp;
s2, adding the modified beta-glucosidase hydrolysate into the cranberry pulp obtained in the step S2, stirring at the rotating speed of 300-500 r/min at the temperature of 50-65 ℃, and reacting at constant temperature for 2-8 hours to obtain cranberry enzymatic hydrolysate; the preparation method of the modified beta-glucosidase hydrolysate comprises the following steps: mixing 5-10 g of beta-glucosidase and 1-2 g of D-glucose-6-phosphoric acid, and diluting to 1-1.5L by using acetic acid-sodium acetate buffer solution;
and S3, freezing, drying and crushing the cranberry enzymatic hydrolysate obtained in the step S2 to obtain cranberry powder.
The components in cranberry flour are very complex, and a large number of phenolic compounds are one of the major classes. The close relationship between the phenolic compounds and the antimicrobial and antioxidant activities exists, and the phenolic compounds are also important indexes for evaluating the cranberry candies. In a large amount of production practices, the inventor finds that a small amount of hydroxypropyl trimethyl ammonium chloride chitosan is added in the process of hydrolyzing the cranberries by using beta-glucosidase and D-glucose-6-phosphoric acid, so that the prepared cranberry powder can not only enhance the antibacterial effect of the cranberry candies, but also delay the decomposition of total phenols in the cranberry candies and prolong the shelf life of the cranberry candies.
In some preferred embodiments, the preparation method of the cranberry powder comprises the following steps:
s1, unfreezing frozen cranberries and pulping to obtain cranberry pulp;
s2, adding the modified beta-glucosidase hydrolysate into the cranberry pulp obtained in the step S2, stirring at the rotating speed of 300-500 r/min at the temperature of 50-65 ℃, and reacting at constant temperature for 2-8 hours to obtain cranberry enzymatic hydrolysate; the preparation method of the modified beta-glucosidase hydrolysate comprises the following steps: mixing 5-10 g of beta-glucosidase, 1-2 g of D-glucose-6-phosphoric acid and 0.1-0.2 g of hydroxypropyl trimethyl ammonium chloride chitosan, and fixing the volume to 1-1.5L by using an acetic acid-sodium acetate buffer solution;
and S3, freezing, drying and crushing the cranberry enzymatic hydrolysate obtained in the step S2 to obtain cranberry powder.
Preferably, the beating rotation speed in the step S1 is 5000-8000 r/min.
Preferably, the volume ratio of the cranberry pulp and the modified beta-glucosidase hydrolysate in the step S2 is 1 (0.6-1).
The pH value of the acetic acid-sodium acetate buffer solution is 5.8-6.2, and the concentration is 30-50 mmol/L.
Preferably, the freeze-drying condition in step S3 is freezing at-20 to-18 ℃ for 12 to 24 hours, and then freeze-drying at-20 to-18 ℃ for 36 to 48 hours.

Test example 1
And (3) testing the antibacterial effect: staphylococcus aureus (ATCC 6538) and Candida albicans (ATCC 10231) were diluted with sterilized physiological saline, respectively, to prepare 100cfu/mL of a Staphylococcus aureus suspension and a Candida albicans suspension. 5g of the candy pieces prepared in examples 1 to 3 and comparative example 1 were added to 100mL of the Staphylococcus aureus suspension and Candida albicans suspension, respectively, at a constant temperature of 37 ℃ and were stirred until dissolved, and the number of colonies in the samples was measured at 0min, 30min, 60min and 120min, respectively, and the results are shown in Table 1. The antibacterial effect takes the percentage of colony number reduction as an evaluation index, and the calculation method of the percentage of colony number reduction is as follows:
percent (%) decrease in colony number = (M) 0 -M n )/M 0 ×100%
Wherein M is 0 The content of microorganisms in the bacteria suspension when the candy pieces are not added initially; m n The content of microorganisms was measured at different times.

As can be seen from table 1, the candy sheets prepared in examples 1 to 4 have an obvious antibacterial effect compared to comparative example 1, which indicates that the antibacterial property of the candy sheets can be improved by adding cranberry powder. Compared with the example 1, the antibacterial property of the candy tablet prepared in the example 2 is obviously improved, which is probably because the beta-glucosidase hydrolyzes glycoside substances in cranberries, so that the content of free aglycone is increased, and the antibacterial property is further improved. The candy tablet prepared in example 3 can reduce bacteria by 80% or more in 30min and by 95% or more in 120 min. The reason is probably that the sugar tolerance and the enzyme activity of the beta-glucosidase are improved due to the D-glucose-6-phosphate, so that the substrate is hydrolyzed completely, the aglycone content of the prepared candy sheet is increased, and the antibacterial effect is more obvious. Example 4, in which a small amount of hydroxypropyltrimethylammonium chloride chitosan was added during the hydrolysis of cranberries, was found to have the best antimicrobial properties with β -glucosidase, D-glucose-6-phosphate. The reason is probably that the hydroxypropyl trimethyl ammonium chloride chitosan is used as a spectrum bacteriostatic agent, and the existence of quaternary ammonium salt improves the bactericidal effect; and possibly, the hydroxypropyl trimethyl ammonium chloride chitosan promotes the action of beta-glucosidase and D-glucose-6-phosphoric acid on cranberry hydrolysis, so that the aglycon content of the prepared cranberry powder is further increased.
Test example 2
And (3) testing the anti-inflammatory effect: 75 subjects are selected, have obvious symptoms of swelling and aching gum, are all patients with swelling and aching gum caused by inflammation of gum caused by excessive internal heat or oral bacteria infection, are divided into 5 groups, 15 people are selected, each group respectively uses the antibacterial and anti-inflammatory cranberry candy tablets prepared in the examples 1-3 and the comparative example 1, 1 tablet is taken at a time, 0.5g is taken at a time, 3 times are taken every day, and 7 days are continuously taken, and no antibacterial and anti-inflammatory product is used in a blank control group. Before and 7 days after taking the candy pieces, the objective gingiva of the subjects in each group was examined using a blunt periodontal probe, and the average of the objective gingiva was taken as a gingival index after being scored according to the gingival score standard of table 2, and the results of the examination are shown in table 3.
TABLE 2 Gum score criteria

Example 2 2.7 1.1
Example 3 2.8 0.6
Example 4 2.7 0.5
Comparative example 1 2.6 2.3
Blank control 2.7 2.8
As can be seen from table 3, compared with the blank control and comparative example 1, the candy tablets prepared in examples 1 to 4 have better treatment effects on the symptoms of swelling and aching of gum caused by inflammation of gum due to excessive internal heat or infection of oral bacteria, which indicates that cranberries have an anti-inflammatory effect on gum. Compared with example 1, the candy tablets of examples 2 to 4 have the most remarkable effect of relieving swelling and aching of gums, probably because glycosides in cranberries are hydrolyzed by beta-glucosidase, and the content of free aglycones is increased. Examples 3 and 4 can restore the gum to a healthy state within 7 days, which may be that D-glucose-6-phosphate is combined with beta-glucosidase to improve the enzyme activity of the beta-glucosidase, so that the content of high-activity aglycone is increased, and the prepared cranberry candy tablet has a better anti-inflammatory effect.
Test example 3
Quercetin is a flavonol compound with various biological activities, and is also one of effective components in cranberry extract. The present invention utilizes a high performance liquid chromatograph to perform quantitative quercetin testing on the cranberry powders prepared in examples 1-3, and the test results are shown in table 4.
Sample treatment: the cranberry powders prepared in examples 1-4 were dried to constant weight, 2.0g each was weighed, wrapped with filter paper, placed in a soxhlet extractor, added with 80ml of methanol, refluxed at 80 ℃ for 4h, recovered, transferred to a 100mL measuring flask, and diluted to the scale with methanol.
Chromatographic conditions are as follows: kromasil C18 (4.6 mm. Times.250mm, 5 μm) column (Eka chemicals AB S-445 80Bohus Sweden) with 60% methanol-water mobile phase, room temperature column flow rate of 1.0mL/min, detection wavelength of 368nm, sample loading of 10 μ L.
And (3) standard curve preparation: precisely weighing 2.28mg of a reference substance quercetin, diluting to 10mL of constant volume, diluting to various concentrations, respectively sampling, and calculating a regression equation by using a least square method with a peak area as a horizontal coordinate and a concentration as a vertical coordinate.
Table 4 cranberry powder quercetin content determination results
Figure BDA0003772311060000151
Referring to table 4, the cranberry powder quercetin content assay results, with the letter differences in table 4 indicating significant differences between groups (P < 0.05). As can be seen from table 4, the content of quercetin in the cranberry powders prepared in examples 2 to 4 was significantly increased (P < 0.05) compared to example 1, which indicates that the content of aglycon in the cranberry powders was increased by hydrolyzing glycosides into aglycon and saccharide by adding β -glucosidase, and further, the antibacterial property and the anti-inflammatory effect of the confectionary tablets prepared in examples 2 to 4 were improved. Compared with the example 2, the beta-glucosidase inactivated by sugar is activated by using D-glucose-6-phosphate, the binding force of the beta-glucosidase and a substrate is improved, glycoside substances in the cranberry are hydrolyzed more completely, the content of quercetin in the cranberry powder prepared in the example 3 is obviously improved (P is less than 0.05), and the antibacterial and anti-inflammatory effects of the candy tablet prepared in the example 3 are more obvious. The candy tablet of example 4 showed the best antibacterial and anti-inflammatory effects, probably because hydroxypropyltrimonium chloride chitosan promoted the hydrolysis of cranberries by β -glucosidase and D-glucose-6-phosphate, increasing the content of free quercetin.
Test example 4
The total phenol content of the cranberry powder prepared by the invention is calculated by the equivalent of gallic acid. The specific test procedure is as follows: dissolving gallic acid in 80vol.% methanol water solution to obtain gallic acid mother liquor with the concentration of 0.1mg/mL, and diluting to obtain a solution to be detected with the concentration range of 0.002-0.01 mg/mL; and (3) taking 250 mu L of solution to be detected, adding 30 mu L of forskolin phenol and 7 mu L of 30vol.% sodium carbonate aqueous solution, reacting for 1h at 25 ℃ in a dark place, and sucking supernatant to test a light absorption value at 725nm to obtain a standard curve of the concentration of gallic acid and the light absorption. The cranberry powder prepared by the method is divided into 6 parts, and each part is 50mg; dissolving three parts of the extract in 10mL of water, and testing the initial total phenol content according to the method; the remaining cranberry powder was then stored at 40 ℃ and tested for total phenolic content after 30 days. The results are shown in Table 5.
TABLE 5 Total phenol content Retention after storage
Total phenol content retention (%)
Example 3 73.1
Example 4 84.6
As can be seen from the test results of table 5, example 4 has higher storage stability. The reason is probably that the hydroxypropyl trimethyl ammonium chloride chitosan promotes the hydrolysis of beta-glucosidase and D-glucose-6-phosphoric acid on cranberries, so that the content of total phenols is increased, the structure of phenol substances is stabilized, and the decomposition of the phenols is inhibited.
