Description

Non-carbonated liquid food and drink containing microbial cells, and method for improving dispersibility of precipitates or aggregates of microbial cell powder in food and drinks

The present invention relates to a non-carbonated liquid food or drink containing microbial cells such as lactic acid bacteria, and a method for improving the dispersibility of precipitates or aggregates of microbial cell powder in such food and drink.

Lactic acid bacteria are attracting attention as a functional ingredient having physiological activity beneficial to health against the background of health-consciousness in recent years. So far, lactic acid bacteria are known to have various physiological activities depending on the strain, such as intestinal regulating action, antiallergic action, cholesterol reducing action, blood pressure lowering action, skin beautifying action, and sleep resting action. In addition, research on lactic acid strains having novel physiological activities is underway. For example, Lactobacillus amylovorous CP1563 strain is effective in improving lipid metabolism and / or sugar metabolism (Patent Documents) 1) It has been reported that the lipid metabolism improving effect is improved by destroying the strain (Patent Document 2). In view of the fact that such lactic acid bacteria can be easily and routinely ingested, lactic acid bacteria-containing beverages are expected to meet the needs of consumers and become increasingly important in the future.

As a method for producing a lactic acid bacteria-containing beverage, for example, a method of blending fermented milk obtained by adding lactic acid bacteria to fermented raw material and fermenting, or a method of blending cell powder obtained by drying lactic acid bacteria cells by freeze drying or the like and so on. However, the lactic acid bacteria-containing beverage produced by such a method has problems such as aggregation or precipitation of milk protein or cell powder in fermented milk during storage, or white turbidity due to fermented milk.

So far, methods for adding stabilizers such as pectin, gums, and soy polysaccharides to suppress the occurrence of precipitation of milk proteins and the like and improve storage stability in lactic acid bacteria-containing beverages (Patent Documents 3 and 4) A method of adding fermented cellulose and soybean polysaccharide (Patent Document 5) has been reported.

In addition, emulsifiers such as glycerin fatty acid ester and sucrose fatty acid ester are used for the purpose of emulsification, dispersion, penetration, washing, foaming, defoaming, mold release and the like during food processing. Often used for the purpose of preventing separation of oils and fats. For example, Patent Document 6 discloses that a milk beverage having a good emulsification state and excellent storage stability can be obtained by using a polyglycerin fatty acid ester and a sucrose fatty acid ester in combination. Patent Document 7 discloses (A) an emulsifier such as sucrose fatty acid ester having an average HLB of 14 or less, (B) crystalline cellulose, (C) xanthan gum, (D) gellan gum, and (E) monosaccharide. By adding an anti-settling agent for protein beverages that contains the components as essential components, of which 4 components (A) to (D) are contained in a specific ratio, the protein beverage can be a high-salt beverage or a low-viscosity beverage. It is disclosed that even a beverage can improve dispersion stability.

However, all the inventions described in Patent Documents 3 to 7 are intended to stabilize by suppressing aggregation of milk protein and promoting dispersion of milk fat, and precipitates and aggregates of microbial cells such as lactic acid bacteria It does not improve the dispersibility.

On the other hand, Patent Document 8 describes “a composition comprising a lactic acid bacterium having an immunostimulatory effect and a composition enhancing a lactic acid bacterium immunostimulatory effect comprising an ester conjugate of a polyhydric alcohol and a saturated fatty acid as an active ingredient”, “Food and drink” is exemplified as “composition”, and “sucrose fatty acid ester” is exemplified as “ester-bound product of polyhydric alcohol and saturated fatty acid”. However, in the invention described in Patent Document 8, the polyhydric alcohol and the saturated fatty acid ester conjugate are only used as components for enhancing the immunostimulatory action of lactic acid bacteria, and the “food” is “beverage”. There is no particular distinction as to whether or not it is other (solid matter, etc.) in relation to the effect. In other words, in Patent Document 8, when a sucrose fatty acid ester having a polyhydric alcohol and a saturated fatty acid ester conjugate, particularly a specific range of HLB, is blended in a “beverage” (for example, a lactic acid bacteria beverage), It is not disclosed that it has the effect of improving the dispersion stability of) so that such a fact can be specifically recognized. In Example 3 and FIG. 3 of Patent Document 8, as sucrose fatty acid esters, sucrose palmitate esters (Ryoto Sugar Esters P-1570, P-1670), sucrose stearates (Ryoto Sugar Esters S- 1570, S-1670) or sucrose oleate (Ryoto Sugar ester O-1570) is disclosed, but “Lactic acid bacteria (JCM5805 strain) prepared in this example and described in FIG. The “sample mixture” is for addition to the cell suspension of spleen cells (Example 1) for verifying the immunostimulatory effect, and is not a “beverage”. Each product of the above sucrose fatty acid ester has been verified only for its immunostimulatory effect when added to cells, and from the perspective of whether it exhibits a practical effect in improving dispersion stability when added to beverages. It has not been verified.

Patent Document 9 describes a food composition containing a lactic acid bacterium belonging to Lactobacillus kunkee or a treated product thereof, and examples of the food composition include beverages. There is no disclosure of further formulating sucrose fatty acid esters having a specific range of HLB. In an example of Patent Document 9, it is described that a mixture of a specific lactic acid bacterium powder and a sucrose fatty acid ester (usually in a powder or paste form) is filled into a hard capsule to obtain a “lactic acid bacterium capsule”. However, the composition is not “beverage”, and the compound names of HLB and fatty acid (residue) of sucrose fatty acid ester are unknown.

Japanese Patent No. 5690416 Japanese Patent No. 5801802 JP 2005-185132 A JP 2006-325606 A (Patent No. 4017175) Japanese Patent Laid-Open No. 2014-19 (Japanese Patent No. 5887991) JP 11-75683 A (Patent No. 3509566) JP 2000-312572 A Japanese Unexamined Patent Publication No. 2016-5452 WO2013 / 099883

When microbial cells such as lactic acid bacteria are to be ingested by non-carbonated liquid foods and beverages (typically non-carbonated beverages), microbial cell powder is included in non-carbonated liquid foods and beverages in order to widen the range of final product forms. In addition, when it is intended to ingest a physiologically active substance present in the inside of the microbial cell, it is preferable that the non-carbonated liquid food or drink contains the destruction-treated microbial cell powder in which the microbial cell is destroyed. However, in this case, the microorganism cell powder tends to form precipitates or aggregates in the non-carbonated liquid food or drink during storage. In particular, in non-carbonated beverages, when the microbial cell powder is a destruction-treated cell powder, the precipitate of the cell powder adheres to the bottom of the container, or the cell powder in the liquid or the precipitate aggregates. As a result, it has been found that it is difficult to ingest physiologically active substances because it is easy to form hard aggregates, and the appearance of non-carbonated beverages is also bad. In addition, when producing foods and drinks other than non-carbonated liquid foods and drinks, for example, jelly-like foods and drinks, microbial cell powder (especially destruction-treated cell powder) aggregates in the solution, and the microbial cell is put in a container. We found the problem that it could not be filled uniformly.

Therefore, in one aspect of the present invention, in a non-carbonated liquid food or drink containing a powder of microbial cells such as lactic acid bacteria, the dispersibility of precipitates and aggregates of the microbial cell powder generated during production and storage It is an object to provide an effective means for improving the above.

As a result of intensive studies to solve the above problems, the present inventors have blended a non-carbonated beverage with a specific type of sucrose fatty acid ester having a specific HLB together with a microbial cell powder such as lactic acid bacteria. The present inventors have found that the dispersibility of precipitates and aggregates of microbial cell powder generated during the production and storage of this non-carbonated beverage can be remarkably improved, and the present invention has been completed. The sucrose fatty acid ester is a compound that has been widely blended in various foods and drinks as a food additive (emulsifier), but the present invention has a specific type of sucrose fatty acid ester having a specific HLB. For example, it is based on having an unexpected attribute (use) that can improve the dispersibility of precipitates and aggregates of microbial cell powder contained in non-carbonated beverages. Furthermore, the present inventors produce not only non-carbonated drinks but also other non-carbonated liquid foods and drinks using a solution (dispersion) of microbial cell powder, which eventually becomes solid. If the same problem occurs during manufacturing and storage, the use of specific sucrose fatty acid esters can also improve the dispersibility of precipitates and aggregates of microbial cells. It has also been found that it can be improved.

In order to solve the above problems, the present applicant uses a polyglycerin fatty acid ester alone or a polyglycerin fatty acid ester and an organic acid monoglyceride together with a microbial cell powder in a carbonated or non-carbonated beverage. (See Japanese Patent Application No. 2016-240827, hereinafter the invention related to the application is referred to as “prior invention”).

The strain belonging to the above-mentioned lactic acid bacterium species used in the non-carbonated liquid food and drink of the present invention may be any of an isolated strain from nature, a deposited strain, a storage strain, a commercially available strain, and the like.

A microbial cell used in the non-carbonated liquid food or drink of the present invention, preferably a microbial cell selected from lactic acid bacteria belonging to the genus Lactobacillus, is usually used using a medium usually used for culturing microbial cells. It can be proliferated and recovered by culturing under conditions.

The culture medium usually contains a carbon source, a nitrogen source, inorganic salts, and the like, and any of a natural medium and a synthetic medium may be used as long as the above-mentioned bacterial species can be efficiently cultured. . As the carbon source, for example, lactose, glucose, sucrose, fructose, galactose, molasses and the like can be used, and as the nitrogen source, for example, casein hydrolyzate, whey protein hydrolyzate, soy protein hydrolysate, yeast Organic nitrogen-containing materials such as extracts and meat extracts can be used.

As the natural medium, tomato juice, carrot juice, other vegetable juice, apple, pineapple, grape juice, etc. can be used.

Cultivation is carried out at 20-50 ° C., preferably 25-42 ° C., more preferably about 37 ° C. under anaerobic conditions. The temperature condition can be adjusted by a thermostatic bath, a mantle heater, a jacket, or the like. The anaerobic condition refers to a low oxygen environment in which bacteria can grow. For example, an anaerobic chamber, an anaerobic box, a sealed container or bag containing an oxygen scavenger, or the like is used. Anaerobic conditions can be achieved by sealing the culture vessel. The culture format is stationary culture, shake culture, tank culture, or the like. The culture time is not particularly limited, but can be, for example, 3 hours to 96 hours. The pH of the medium at the start of the culture is preferably maintained at 4.0 to 8.0, for example.

For example, when a lactic acid bacterium, Lactobacillus amyloborus CP 1563 strain (Accession No. FERM BP-11255) is used as a microbial cell, the lactic acid bacterium is inoculated in a medium for food grade lactic acid bacteria and is overnight at about 37 ° C. (about 18 hours).

The “microbial cell powder” used in the non-carbonated liquid food and drink of the present invention is obtained by drying a culture solution of microbial cells using a method and equipment known in the art to form a powdery product. Obtainable. Specific drying methods are not particularly limited, and examples include spray drying, drum drying, hot air drying, vacuum drying, freeze drying, and the like, and these drying means can be used alone or in combination.

The microbial cell powder is damaged by destroying the cell structure of the microbial cell, and is made into a finer powder than the microbial cell powder simply dried by freeze drying or other methods. It may be “powder”. The destruction-treated microbial cell powder can be obtained by recovering the entire destroyed microbial cell body (that is, essentially all components constituting the cell) as they are.

The destruction treatment of the microbial cells can be performed by, for example, physical crushing, grinding treatment, enzyme dissolution treatment, chemical treatment, self-dissolution treatment, or the like using methods and equipment known in the art.

Physical crushing may be carried out either wet (treating microbial cells in suspension) or dry (treating in microbial powder) using a homogenizer, ball mill, bead mill, planetary mill, etc. By the agitation, the microbial cells can be damaged by pressure using a jet mill, a French press, a cell crusher or the like, or by filter filtration.

The enzyme dissolution treatment is performed, for example, by destroying the cell wall of the microbial cell body using an enzyme such as lysozyme.

The chemical treatment is performed by destroying the cell structure of the microbial cell using a surfactant such as glycerin fatty acid ester and soybean phospholipid.

The self-dissolution treatment is performed by dissolving microbial cells with the enzyme of the microorganism itself.

Among the above treatments, physical crushing is preferable because it is not necessary to add other reagents or components, and dry physical crushing is more preferable.

More specifically, the physical crushing is performed by using various known ball types (eg, zirconia 10 mm ball, zirconia 5 mm ball, alumina 1 mm ball) in a known dry planetary mill cell crusher (GOT5 Galaxy 5 or the like). ) A method of treating at a rotational speed of 50 to 10,000 rpm (for example, 190 rpm) for 30 minutes to 20 hours (for example, 5 hours) in the coexistence, a known dry jet mill cell crusher (such as a jet O-mizer) 1 to 10 times (for example, at a supply rate of 0.01 to 10,000 g / min (for example, 0.5 g / min) and a discharge pressure of 1 to 1,000 kg / cm ² (for example, 6 kg / cm ² )). Once) can be performed by a method of processing. In addition, the suspension of the microbial cells is circulated at a peripheral speed of 10.0 to 20.0 m / s (for example, about 14.0 m / s) using glass peas in a known dynomill cell crusher (such as a DYNO-MILL crusher). s), a method of treating 1 to 7 times (eg, 3 to 5 times) at a crushing tank temperature of 10 to 30 ° C. (eg, about 15 ° C.) at a treatment flow rate of 0.1 to 10 L / 10 min (eg, about 1 L / 10 min) The microbial cell suspension is discharged in a known wet jet mill cell crusher (such as JN20 Nanojet Pal) at a discharge pressure of 50 to 1,000 MPa (for example, 270 MPa) and a processing flow rate of 50 to 1,000 ml / min (for example 300 ml). / Min) at a time of 1 to 30 times (for example, 10 times).

The destruction-treated microbial cells obtained by the above method can be used as they are in the case of a dry type or dried to be a powdery product in the case of a wet type. Specific drying methods are not particularly limited, and examples include spray drying, drum drying, hot air drying, vacuum drying, freeze drying, and the like, and these drying means can be used alone or in combination.

The content of the microbial cell powder (A) in the non-carbonated liquid food or drink of the present invention is not particularly limited, but is an amount that can be expected to have physiological activity (for example, an effect of improving lipid metabolism and / or sugar metabolism). For example, 0.001 to 1.0 mass%, more preferably 0.01 to 0.1 mass%.

[Sucrose fatty acid ester]
The non-carbonated liquid food and drink of the present invention includes a sucrose fatty acid ester having a specific HLB, that is, a sucrose stearate having an HLB of 8 to 12 and a sucrose oleic acid having an HLB of 14 to 16 together with a microbial cell powder. Ester, sucrose laurate having an HLB of 15 to 17, sucrose palmitate having an HLB of 14.5 to 15.5, or sucrose myristate having an HLB of 15 to 17 is blended. Any one of these sucrose fatty acid esters may be used, or two or more thereof may be used in combination.

Sucrose fatty acid ester is a compound that is permitted as a food additive (food emulsifier) in the Food Sanitation Law. It is a nonionic surfactant that has sucrose as a hydrophilic group and ester-bonded fatty acid as a lipophilic group. is there. One molecule of sucrose has 8 hydroxyl groups, and one or more fatty acids are ester-bonded to the hydroxyl groups, so that they exist from monoesters to octaesters. Sucrose glyceric acid ester is usually produced and sold as a composition containing plural kinds of compounds from monoester to octaester. The HLB varies depending on the type of fatty acid and the proportion of each ester compound contained (the composition of the ester compound). Generally, the more ester compounds having a smaller number of fatty acid bonds, the more sucrose as the composition. The HLB of the fatty acid ester becomes large (hydrophilic), and the more the ester compound having a larger number of fatty acid bonds, the smaller the HLB of the sucrose fatty acid ester as a composition (which is lipophilic). In other words, the smaller the average number (average number of bonds) of fatty acid bonds per molecule of sucrose, the higher the HLB of the sucrose fatty acid esters, and the larger the average number of fatty acid bonds, the more sucrose fatty acid esters. The HLB becomes smaller.

A sucrose fatty acid ester having a desired HLB can be produced by a known method (for example, a transesterification reaction between sucrose and a higher alcohol ester of a fatty acid), and can also be obtained as a commercial product. Examples of the sucrose stearate having an HLB of 8 to 12 include “Ryoto (registered trademark) sugar ester”, brand “S-970” (HLB = about 9), “S-1170” manufactured by Mitsubishi Chemical Foods Corporation. (HLB = about 11); As a sucrose oleate having an HLB of 14 to 16, the same “O-1570” (HLB = about 15); As a sucrose laurate having an HLB of 15 to 17, L-1695 ”(HLB = about 16); sucrose palmitate ester having an HLB of 14.5 to 15.5 is also“ P-1570 ”(HLB = about 15); sucrose having an HLB of 15 to 17 As the myristic acid ester, “M-1695” (HLB = about 16) is also mentioned.

The HLB for the above products is outlined in the catalog (Mitsubishi Chemical Foods website, http://www.mfc.co.jp/product/nyuuka/ryoto_syuga/list.html) ("About") Although described, the above-mentioned integer is represented as an approximate value by rounding off to the nearest decimal point. For example, if the HLB is “about 9”, it is estimated to be “8.5 or more and less than 9.5”. When using other products, HLB can refer to catalog values. When the catalog value is unknown or when the sucrose fatty acid ester is prepared and used by itself, the HLB can be determined according to a known method. The calculation method of HLB includes Atlas method, Griffin method, Davis method, Kawakami method and the like, and there is also a method of determining from the retention time in high performance liquid chromatography. In the present invention, (i) when the composition of the sucrose fatty acid ester (mixture) is known, after calculating the HLB of each compound by the Griffin method, the weighted average is assumed to be the HLB of the sucrose fatty acid ester, (Ii) If the composition of the sucrose fatty acid ester (mixture) is not known, the HLB of the sucrose fatty acid ester is determined from the retention time in high-performance liquid chromatography by comparison with a sample of sucrose fatty acid ester with a known HLB. We will ask for it.

The content of the specific sucrose fatty acid ester (B) having a specific HLB in the non-carbonated liquid food or drink of the present invention should be appropriately adjusted in consideration of the effect of improving the dispersibility of the microbial cell powder (A). Can do. The lower limit of the content of the sucrose fatty acid ester (B) in non-carbonated liquid foods and beverages, preferably non-carbonated beverages is preferably 0.001% by mass, more preferably 0.01% by mass, and further 0.02% by mass. Preferably, 0.04 mass% is particularly preferable, and 0.05 mass% is most preferable. Moreover, 0.2 mass% is preferable, as for the upper limit of content of sucrose fatty acid ester (B) in non-carbonated liquid food / beverage products, Preferably a non-carbonated drink, 0.15 mass% is more preferable, 0.11 mass% Is more preferable. If the lower limit is lower than this, the effect of dispersibility cannot be expected, and if the upper limit is higher than this, it is not desirable from the viewpoint of flavor, cost, and liquid color turbidity.
