Description

Active probiotic antioxidation soft sweet and preparation method thereof
Technical Field
The invention relates to the technical field of food processing, in particular to an active probiotic anti-oxidation soft candy and a preparation method thereof.
Background
The probiotics are living microorganisms which can produce beneficial effects on the health of a host after being ingested in a certain amount, can be used as auxiliary materials to be added into corresponding functional foods for maintaining the balance of intestinal flora, and can also be directly eaten. A large number of researches prove that the probiotics have various physiological effects, such as improving human intestinal environment, regulating flora balance, enhancing organism immunity, relieving allergic symptoms and the like. Common probiotics can be classified into lactic acid bacteria (such as bifidobacterium adolescentis, bifidobacterium animalis, lactobacillus acidophilus, lactobacillus casei, lactobacillus bulgaricus, lactobacillus plantarum, streptococcus thermophilus, etc.), bacillus (such as bacillus subtilis, bacillus coagulans, etc.), and a part of fungi (such as saccharomyces boulardii, saccharomyces cerevisiae, etc.). Among them, lactic acid bacteria are the most important components in the family of probiotics, and are also the most widely used type of probiotics in the field of food processing at present. The probiotic food industry in China starts later, the probiotic food is mainly concentrated on fermented milk, formula milk powder, instant fungus powder and fermented beverage, and the product structure is relatively single. Most of probiotics applied to food are lactic acid bacteria, and the developed and utilized probiotics are relatively few. In addition, the lactobacillus has the property of natural intolerance to high temperature, loses activity under relatively extreme processing conditions, and is difficult to play the effect of probiotics, thus greatly limiting the wide application of the lactobacillus in the food industry. Bacillus coagulans (Bacillus coagulans) is a class of bacteria that can metabolize to produce L-lactic acid and form spores. It not only has the properties of acid production, bacteriostasis and the like of lactic acid bacteria, but also can metabolize to produce spores, thereby having the stress resistance characteristics of high temperature resistance, bile salt resistance, acid resistance and the like. Bacillus coagulans has therefore received general attention from various industries, once as a specific sporulated lactic acid bacterium has been increasingly accepted by the market.
Haematococcus pluvialis is a single-cell microalgae, and is widely paid attention to because it contains abundant astaxanthin. Astaxanthin is the most efficient pure natural antioxidant and is known as "antioxidant king". A large number of researches show that astaxanthin has the effects of delaying aging, reducing blood fat, preventing cardiovascular diseases, inhibiting tumors and enhancing immunity. The haematococcus pluvialis is the most abundant organism in nature, and the maximum astaxanthin content can reach more than 3.0 percent (dw), and is known as a concentrated product of natural astaxanthin. Astaxanthin from Haematococcus pluvialis has incomparable advantages in terms of functionality and edible safety as well as astaxanthin from other sources. Therefore, haematococcus pluvialis is considered as the best biological source of natural astaxanthin, has high nutritional and medicinal values, and is widely applied to the industries of functional foods and health care products as a new resource food raw material in recent years.
The soft candy is a leisure snack which is suitable for people of all ages, and is popular with consumers due to the advantages of gorgeous and attractive color, good taste, portability and the like. With the improvement of living standard, people put forward higher requirements on leisure snacks, the traditional soft sweets which only depend on superior appearance and extremely good taste experience cannot meet the requirements of modern people on healthy consumption, and the development of novel probiotic functional soft sweets is an important direction of future development. At present, the quality of the probiotic soft sweet products on the market is uneven, although the content of the viable bacteria of the probiotic which is declared by the products is very high, as the probiotic preparation added in the traditional soft sweet is lactic acid bacteria with poor stability, the viable bacteria in the shelf life of the products is difficult to ensure, and the probiotics which can keep the activity and enter the intestinal tract to play the probiotic effect are fewer due to the extreme environmental effects of the digestive tract and the like of the human body. The bacillus coagulans has the functions of lactic acid production and intestinal flora regulation of lactic acid bacteria, and also has the stress resistance characteristics of high temperature resistance, bile salt resistance, acid resistance and the like, so that the pain points of the lactic acid bacteria, which are easy to inactivate and have poor stability in the processing process, can be overcome, the higher activity of the lactic acid bacteria can be kept to enter human intestinal tracts, and the probiotic soft sweet is an ideal probiotic preparation in the current probiotic soft sweet processing application. However, the application of Bacillus coagulans to soft candy products has been rarely reported.

Specifically, the type of the edible gelatin comprises at least one of 120 power, 160 power and 250 power, preferably 250 power edible gelatin, and the soft candy prepared by using the edible gelatin has no gelatin odor residue and has more moderate hardness, chewing property and gumminess.
The lemon juice is formed by leaching lemon scraps at low temperature.
The first sweetener is white granulated sugar; the second sweetener is sugar alcohol liquid. Further, the sugar alcohol solution includes at least one of a maltitol solution, a xylitol solution, an erythritol solution and a sorbitol solution, preferably a maltitol solution.
As the haematococcus pluvialis contains abundant astaxanthin, the astaxanthin is the most efficient pure natural antioxidant and is beneficial to improving the antioxidant capacity of the soft sweet.
In the embodiment, the selected bacillus coagulans powder has the advantages of strong stress resistance, high temperature and high pressure resistance and easy storage compared with other probiotics.
The Euglena powder can provide nutrients such as amino acids, minerals, vitamins, polyunsaturated fatty acids (such as EPA and DHA) and polysaccharides.
Prebiotics are dietary supplements that beneficially affect the host by selectively stimulating the growth and activity of bacteria in one or a few colonies, thereby improving the health of the host's indigestible food ingredient. In this embodiment, the compound prebiotics are a composition of fructo-oligosaccharide and galacto-oligosaccharide, and the mass ratio of the fructo-oligosaccharide to the galacto-oligosaccharide is (0.3-0.5): (0.8-1.2), and the addition of the two is beneficial to improving the proliferation capability of bacillus coagulans.
According to the active probiotic anti-oxidation soft sweet provided by the first aspect of the invention, by adding two raw materials of haematococcus pluvialis and euglena powder, algal polysaccharide, vitamins, polyunsaturated fatty acids (DHA, EPA and the like) and a plurality of nutritional ingredients such as minerals are introduced, and meanwhile, the anti-oxidation capability of the soft sweet is improved. In addition, the probiotics preparation used in the invention is bacillus coagulans, has strong stress resistance characteristics such as high temperature resistance, bile salt resistance, acid resistance and the like, and can well overcome the defects that probiotics are easy to inactivate and poor in stability in the processing process of the traditional probiotics soft sweets. In addition, the addition of the composite prebiotics can well promote the proliferation of bacillus coagulans and improve the survival stability of the bacillus coagulans, so that the advantage that the probiotics promote the intestinal health of a human body can be effectively exerted.
Referring to fig. 1, the invention also provides a preparation method of the active probiotic antioxidation soft candy, which comprises the following steps:
a preparation step of freshly squeezed lemon juice, which is to pretreat fresh lemon to obtain freshly squeezed lemon juice;
specifically, cleaning fresh lemon, squeezing pulp to obtain juice, treating lemon peel with a grinder to obtain lemon peel, adding the juice, extracting at low temperature below 4deg.C for 4 hr, and filtering to obtain freshly squeezed lemon juice. The lemon juice is added on one hand to cover the fishy smell of the euglena and haematococcus pluvialis, improve the flavor of the soft sweet and improve the overall juice feel of the soft sweet, and the lemon scraps are extracted at low temperature after the juice is taken, so that the flavor substances on lemon peels are mainly extracted, and the flavor with more layers is obtained. On the other hand, the vitamin C content of the lemon juice is up to 27.34-119.4 mg/100mL, and the vitamin C content of the soft sweets can be obviously improved by adding the lemon juice.
The preparation method comprises the steps of uniformly mixing a first sweetener, a composite prebiotic, sodium citrate and euglena powder, adding hot water at a first preset temperature, continuously stirring, sequentially adding a second sweetener and the obtained freshly squeezed lemon juice, homogenizing at a preset rotating speed for a period of time, heating the mixed syrup to a second preset temperature, preserving heat, cooling, and adding haematococcus pluvialis powder and bacillus coagulans powder when the sugar solution is cooled to a third preset temperature, and uniformly stirring to obtain a probiotic syrup premix; wherein the second preset temperature is greater than the first preset temperature, which is greater than or equal to the third preset temperature;
homogenizing treatment can be carried out by adopting a high-speed dispersion homogenizer, and the preset rotating speed is 7000-10000rpm; preferably 8000rpm. The first preset temperature is 55-65 ℃, preferably 60 ℃, so as to better dissolve various powder substances sufficiently; the second preset temperature is 75-85 ℃, preferably 80 ℃, to perform pasteurization; since a certain temperature is required for the sufficient dissolution of haematococcus pluvialis powder and bacillus coagulans powder, however, too high a temperature damages active ingredients (astaxanthin and the like) of haematococcus pluvialis powder and may cause inactivation of bacillus coagulans, the third preset temperature is 45-55 ℃; preferably 50 ℃.
And (3) a gelatin dissolving step, namely mixing the edible gelatin with the drinking water with the same quality, fully soaking for a period of time, and then dissolving the pre-soaked edible gelatin at the water bath temperature of 70-90 ℃.
Specifically, the consumption of the drinking water for dissolving the edible gelatin is 12.5-17 parts; the water bath temperature is preferably 70 ℃.
And a blending step, namely adding the probiotics syrup premix to stir and blend after the edible gelatin is homogenized, and blending for a period of time at 70-90 ℃ to obtain the soft candy gel mixed solution.
Specifically, as experiments show that the survival amount of probiotics and the antioxidation capability in the soft candy are reduced along with the rising of the blending temperature, the survival amount of the probiotics in the soft candy can reach 8.56Lg (CFU/g) when the blending temperature is 70 ℃, and the DPPH free radical clearance rate is 36.77%, so that the blending temperature is preferably 70 ℃; the tempering time may be 5-20min, preferably 10min.

Adjusting the final bacterial density OD of the seed culture solution by using sterile physiological saline 600 After a value of 1.2, the mixture was treated in water baths at 75 ℃, 85 ℃ and 95 ℃ for 10min, respectively, and then taken out and rapidly cooled to room temperature. Taking 1mL of treated bacterial liquid respectively, carrying out proper dilution, and then measuring the viable count of bacillus coagulans in each treatment liquid, and evaluating the high temperature resistance of the strain according to the survival rate of bacillus coagulans, wherein the calculation formula of the survival rate is as follows:
wherein: n (N) 0 To treat the viable count of bacillus coagulans in the pre-bacterial liquid, N 1 The bacillus coagulans viable count in the treated bacterial liquid is obtained.
As can be seen from FIG. 2 (A), the survival rate of Bacillus coagulans is up to 80% after 10min of treatment at 75deg.C, and up to 75% after 10min of treatment at 95deg.C, thus the Bacillus coagulans selected in this example has good high temperature resistance.
(2) Acid resistance test: adjusting the pH of LB liquid medium to 2.0, 3.0, 4.0 and 7.0 (pH 7.0 is used as control group) with hydrochloric acid solution or sodium hydroxide solution, inoculating seed liquid of Bacillus coagulans at 0.1% of inoculum size after sterilization, culturing in constant temperature water bath oscillator at 43deg.C and 160rpm for 24 hr, and determining OD of each culture solution 600 And (3) evaluating the acid resistance of the strain.
As can be seen from fig. 2 (B): the bacillus coagulans has a bacterial density of above 0.4 under the environment of pH of 2.0 and has certain activity.
(2) Growth ability and acid production performance: preparing LB liquid culture medium, inoculating seed liquid of Bacillus coagulans at 0.1% of inoculation amount after sterilization, then placing in a constant-temperature water bath at 43 deg.C and 160rpm for shake culture for 24h, taking bacterial liquid for culturing for 0h, 2h, 4h, 8h and 24h, and determining OD of each culture liquid 600 The value and the pH value, thereby evaluating the growth capacity and the acid production capacity of two strains。
As can be seen from FIGS. 2 (C) and (D), bacillus coagulans selected in this example had a strong growth ability and acid-producing ability.
Test example 2
To examine the effect of fructo-oligosaccharides, galacto-oligosaccharides and euglena powder on the proliferation of bacillus coagulans, the following test was performed as follows:
preparing LB liquid culture medium, adding 0%, 0.1%, 0.25%, 0.5% and 1.0% fructo-oligosaccharide or galacto-oligosaccharide (0% added amount is used as control group), sterilizing, inoculating Bacillus coagulans seed liquid according to 0.1% inoculating amount, placing at 43deg.C, shake culturing in constant temperature water bath at 160rpm for 24 hr, and measuring OD of each culture solution 600 Value in OD 600 Values and promotion ratios the effect of fructo-and galacto-oligosaccharides on bacillus coagulans proliferation was evaluated and the promotion ratio was calculated as follows:
wherein: initial OD 600 To absorbance at 600nm of the culture medium at 0h of culture, final OD 600 For absorbance at 600nm at 24h incubation.
Impact test of Euglena powder on Bacillus coagulans proliferation: preparing LB liquid culture medium, adding 0%, 0.25% and 0.5% of Euglena powder (taking 0% of the added amount as a control group) respectively, sterilizing, inoculating Bacillus coagulans seed liquid according to 0.1% of the inoculated amount, and then placing in a constant-temperature water bath at 43 ℃ and 160rpm for shake culture for 24 hours. Because of poor solubility of the euglena powder, the euglena powder can be used for OD of various bacterial liquids 600 The measurement of the value affects the number of viable bacteria in each culture. The effect of euglena powder on the proliferation of bacillus coagulans was evaluated in terms of viable count and promotion ratio.
Wherein: n (N) 0 N is the number of viable bacteria of the bacillus coagulans in the culture solution of the control group 1 The number of viable bacteria of the bacillus coagulans in the culture solution in the test group.
As can be seen from FIGS. 3 (A) and (B), both fructo-oligosaccharide and galacto-oligosaccharide have good promotion effect on the proliferation of Bacillus coagulans 01, and the optimal promotion ratio is more than 30%, wherein the optimal addition amount of fructo-oligosaccharide for promoting the proliferation of Bacillus coagulans is 0.25%, and galacto-oligosaccharide is 0.5%. As is clear from fig. 3 (C), euglena powder also shows a certain acceleration effect on the proliferation of bacillus coagulans, but the acceleration ratio is low. The accelerating effect of the euglena powder on the proliferation of bacillus coagulans can be related to active polysaccharide, special protein and other components contained in the euglena powder, and the components have certain accelerating effect on the proliferation of bacillus coagulans. Because the solubility of the euglena powder in the system is poor, the maximum adding amount of the euglena powder in the test is 0.5%.
Test example 3
The probiotic soft candy samples prepared in example 1 and comparative example 1 were subjected to determination of the viable count of probiotics, wherein the viable count of lactic acid bacteria and bacillus coagulans were determined using MRS solid medium and LB solid medium, respectively.
As can be seen from fig. 4, under the same processing conditions, the survival amount of the probiotics in the probiotic soft candy sample added with the bacillus coagulans powder reaches 8.36Lg CFU/g, which is significantly higher than that of the probiotic soft candy sample added with the composite lactobacillus powder with the same quality (the survival amount of the probiotics is only 3.39Lg CFU/g). It can be seen that the addition of bacillus coagulans maintains the viable count in the probiotic gummy candy at a high level, which may be related to the metabolizable production of spores from bacillus coagulans, and thus the high temperature resistance properties not possessed by lactobacillus species.
Test example 4
The DPPH radical scavenging ability was measured on the probiotic fondant samples of example 1 and comparative example 1, and the antioxidant ability was evaluated as DPPH radical scavenging rate. The method comprises the following steps:
1mL of the methanol extract of the soft candy sample was mixed with 5mL of DPPH methanol solution (0.1 mmol/L). The mixture was reacted for 20min in the dark, and then the absorbance at 517nm was measured, and the DPPH radical scavenging rate was calculated as follows:
wherein: a is that 1 A is the absorbance of the sample reaction solution at 517nm 0 The absorbance at 517nm was used as a blank reaction solution.
As can be seen from FIG. 5, the general fondant without adding haematococcus pluvialis prepared in comparative example 1 had a DPPH radical scavenging rate of 31.68%, while the fondant containing haematococcus pluvialis prepared in example 1 had a DPPH radical scavenging rate of 34.76%, indicating that the addition of haematococcus pluvialis can improve the oxidation resistance of the fondant.
The DPPH radical scavenging ability and the viable count were measured for the probiotic gum samples of example 1, comparative example 2 and comparative example 3, and reference was made to test example 4 and test example 3, respectively. As can be seen from fig. 6A and 6B, the probiotic survival and the antioxidant capacity in the jelly tended to decrease with increasing tempering temperature. When the blending temperature is 70 ℃, the survival rate of probiotics in the soft candy can reach 8.56Lg (CFU/g), and the DPPH free radical clearance rate is 36.77%. Therefore, the temperature of the processing tempering of the soft candy is preferably 70 ℃.
Test example 5
The probiotic soft candy samples of example 1 were stored at room temperature, and the viable count was measured by taking samples stored for 0d, 15d, and 30d, respectively.
TABLE 1 variation of Bacillus coagulans survival during storage of probiotic gummy candy
As can be seen from Table 1, the viable count of Bacillus coagulans in the probiotic soft candy sample shows a decreasing trend during the storage period, and after 30d of storage at normal temperature, the number of Bacillus coagulans in the sample is only decreased by 9.57% and is 7.73Lg CFU/g, and the minimum limit standard (7.0 Lg CFU/g) of probiotic food can still be reached, thus showing that the Bacillus coagulans selected by the invention has good storage stability.
In conclusion, the active probiotic anti-oxidation soft sweet provided by the invention is characterized in that the haematococcus pluvialis powder and the euglena powder are added, so that a plurality of nutritional ingredients such as algal polysaccharide, vitamins, polyunsaturated fatty acids (DHA, EPA and the like) and minerals are introduced, and meanwhile, the anti-oxidation capability of the soft sweet is improved. In addition, the probiotics preparation used in the invention is bacillus coagulans, has strong stress resistance characteristics such as high temperature resistance, bile salt resistance, acid resistance and the like, can well overcome the defects of easy inactivation and poor stability of probiotics in the processing process of the traditional probiotics soft candy, and in addition, the addition of fructo-oligosaccharide and galacto-oligosaccharide can well promote the proliferation of bacillus coagulans and improve the survival stability of bacillus coagulans, thereby effectively playing the effect of promoting the intestinal health of human bodies by the probiotics.
