Description

Description Highly dispersible food additive and food composition containing the same

TECHNICAL FIELD The present invention relates to a food additive having good dispersion stability in a liquid, which is effectively added to foods such as yogurt, milk, juices and the like to enhance calcium, Z or iron. Background art

In recent years, a lack of calcium intake has been pointed out, and this tendency is remarkable in growing children and elderly people. In order to resolve this shortage of calcium intake, calcium-enriched foods have been sold, and even in milk, which is generally said to have a high calcium content, additional calcium is added to calcium. Attempts have been made to provide it as fortified milk, and there are many other products that have been fortified with yogurt, juice and milk.

For example, for the purpose of strengthening calcium in acidic foods such as yogurt, water-soluble inorganic or organic acids such as calcium lactate and calcium chloride, water-insoluble inorganic forms such as calcium carbonate, calcium carbonate, calcium phosphate, etc. Angry calcium is added and used.

However, water-soluble calcium in the form of inorganic or organic acid calcium easily inhibits the stability of protein in yogurt, so it is difficult to mix more than a certain amount and calcium cannot be used in large quantities as a raw material for calcium. Had disadvantages.

On the other hand, calcium in a water-insoluble inorganic form does not inhibit the stability of proteins in yogurt due to its water-insolubility, and although it can be used in large amounts from the viewpoint of the amount added, Calcium in general has a specific gravity as high as around 3, and when it is dispersed in yogurt, it precipitates in a short time. Because of the precipitation, it is not preferable from the viewpoint of aesthetics as a food, and the amount of addition is limited, so that it cannot be used in large quantities.

As a method for preparing a calcium agent slurry in an inorganic form used for food use, for example, in yogurt, a method of simultaneously adding quartz cellulose and supporting calcium carbonate particles by a mesh structure thereof (Japanese Patent Application Laid-Open No. Sho 56-86) Improve the dispersibility of calcium carbonate by irradiating ultrasonic waves to calcium carbonate or slurry carbonate or calcium carbonate with a hydrophilic emulsifier of HLB 10 or more added. (Japanese Patent Application Laid-Open No. S64-69513) has been proposed.

However, in the method of adding the crystalline cellulose as Sho 5 6 1 7 7 5 3 No., have name on texture preferable because拈度product is very high ₀

Also, as disclosed in JP-A-64-69513, the method of dispersing calcium carbonate slurry by using a sucrose fatty acid ester as an additive is a method for dispersing neutral or weakly acidic substances such as milk. It has only a somewhat effective effect on the product, and for example, for products exhibiting an acidic region such as yogurt, the sucrose fatty acid ester tends to be unstable to acids. It tends to cause poor dispersion, which is not preferable.

In addition, in the case of these methods, the solid concentration of calcium carbonate in the aqueous dispersion is extremely low at around 10% by weight. Not only is the cost extremely high, but the form is an aqueous dispersion, so it is easily rotted, and it is necessary to always carry out refrigerated transport and refrigerated storage. I can't say.

Recently, yogurt, milk and juice liquid foods for drinks and evening drinks can be stored for a long time, and with the advancement of storage methods, the foods can be stored for a long time in stores, vending machines, large refrigerators at home, etc. Inorganic calcium salt particles added for the purpose of fortifying calcium to liquid foods of the same type are likely to be long if the dispersion in the food is not good. May settle on the bottom of the food container during the storage of liquid food for a period of time, and when drinking yogurt, milk, or juice liquid food, the precipitate may cause discomfort or impureness to the drinker. There are many.

Therefore, the liquid foods that are commercially available with the addition of inorganic potassium salt particles prepared by conventional techniques for the purpose of fortifying calcium have a short dispersion stabilization period of the inorganic algae in foods. The amount of added food is limited to a very small amount, and the general consumer must be restricted to liquid foods that can be used for food within 1-2 days after insertion. .

On the other hand, in recent years, many women have developed anemia due to iron deficiency. This tendency is particularly noticeable in high school girls and young adult women. The main cause of this deficiency anemia is dietary habits.However, in women, anemia due to iron deficiency such as physiological bleeding, increased iron demand due to pregnancy, and insufficient intake due to diet It is generally said that about half of women are deficient in iron. In order to resolve this iron deficiency, iron-enriched foods are being sold, and a number of products that have iron-enriched milk, soft drinks, etc. have begun to be sold.

For example, in soft drinks, etc., water-soluble organic or inorganic iron such as iron lactate, sodium iron citrate, ferrous gluconate, and ferric pyrophosphate, etc. Water-insoluble or hardly soluble inorganic forms of iron are used. However, water-soluble organic or inorganic forms of iron have a strong taste, and have the drawback of not being able to use too much at once due to the problem of swine. Also, when a water-insoluble or hardly soluble inorganic dispersion of iron such as ferric pyrophosphate is used, the density of iron is improved, but the specific gravity is as high as 2.75 or more. When dispersed, it precipitates in a short period of time, which is not desirable in terms of aesthetics as a food, and has the disadvantage that the amount of addition is limited and cannot be used in large quantities.

In view of the above-mentioned problems, the present invention solves the above-mentioned problems, is excellent in distribution economics, and has good long-term dispersion stability in liquid foods. A calcium agent for adding the food and And / or a food composition containing an iron agent. Disclosure of the invention

Honkiaki et al. Have conducted intensive studies in order to solve the above-mentioned problems. As a result, by using a specific and specific amount of a hydrophilic emulsifier, a calcium agent for a food additive having good long-term dispersion stability can be obtained easily. The present invention has been completed by finding that iron can be obtained.

That is, the present invention relates to at least one of propylene glycol alginate (hereinafter referred to as PGA) selected from the group consisting of calcium carbonate, calcium phosphate (hereinafter referred to as calcium) and ferric pyrophosphate. C), and a food composition containing the food additive. BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, the present invention will be described in detail.

Examples of the calcium carbonate used in the present invention include coral calcium carbonate, heavy calcium carbonate, and synthetic calcium carbonate containing 50% by weight or more of calcium carbonate. Synthetic calcium carbonate prepared by a chemical synthesis method typified by a carbon dioxide method of reacting carbon dioxide gas is preferred. The following method can be exemplified as a preferable method for preparing synthetic calcium carbonate in the carbon dioxide method.

The lime milk is subjected to a carbonation reaction using carbon dioxide gas, and in the step of preparing a calcium carbonate water immersion liquid, a calcium carbonate water suspension liquid having a PH value of K prepared after the completion of the carbonation reaction is stirred. And / or wet milling, and Z or standing, and raise the pH of the calcium carbonate water suspension to a pH value L satisfying the following equations (a) and (b). Remove the alkaline substances present in the liquid and / or reduce the concentration per unit volume of the alkaline substances. The pH of the water suspension of calcium carbonate is calculated by the following formula (c) Adjust to pH value M that satisfies to prepare calcium carbonate.

L≥ B. 6 (a)

1 0 ", / 1 0 ^K ≥ 1 25 (b)

1 0 ^{fM +} / l 0 ^L ≤ 8 0 (c)

Here, K and L are pH values under the same temperature condition. If the pH value M is less than 8.6, calculate M as 8.6.

The calcium phosphate used in the present invention refers to an inorganic material composed of a calcium salt of phosphoric acid. Examples of calcium phosphate include natural calcium phosphate containing 50% by weight or more of calcium fanate, bovine bone, and synthetic calcium phosphate. Synthetic calcium phosphate prepared by a chemical synthesis method in which a calcium salt such as calcium hydroxide, calcium carbonate or calcium chloride is reacted with a phosphate such as acid or sodium phosphate is preferred. Among them, at least one calcium phosphate selected from the group consisting of dihydrogen pyrophosphate diacid, calcium hydrogen phosphate and tricalcium phosphate is more preferred.

As for the calcium agent used as a raw material of the present invention, that is, calcium carbonate and Z or calcium phosphate, an aqueous suspension of calcium agent prepared by a usual method may be used. An aqueous suspension prepared by adding water again to the calcium agent powder prepared through dehydration, drying, and pulverization according to a conventional method may be used, but strict adherence to food additive standards and hygiene control From the viewpoint, it is preferable to adopt the latter form.

When used in the latter method, the pH of the calcium carbonate powder to be used is determined from the viewpoint of preventing the functional deterioration of the hydrophilic emulsifier used in the present invention and increasing the efficiency of pulverization and separation. The solids concentration of the body 20 weights A suspension of 200 cc of water in 96 cc was sonicated at 300 W, 20 kHz for 10 min. It is preferable to use the following carbonic acid powder, more preferably 11.5 or less.

Further, the specific surface area of the calcium agent used as a raw material of the present invention by a nitrogen adsorption method (BET method) is preferably in the range of 6 nf / g to 60 rrfZg. Specific surface If the product is less than 6 irf / g, long-term stability in liquid foods such as milk will be problematic, and if it exceeds 6 O irf / g, the cohesive force of the calcium agent powder will be extremely strong. Therefore, its dispersion becomes difficult.

The ferric pyrophosphate used in the present invention may be a synthetic ferric pyrophosphate obtained by chemically synthesizing. The method is exemplified below.

Dissolve ferric chloride in water, mix with this solution a solution of sodium pyrophosphate in warm water, and stir. After the completion of the reaction, the solution is dehydrated using a filter press, water is again added to the obtained dehydrated cake, and the mixture is stirred to obtain an aqueous solution of ferric pyrophosphate having the same concentration as before dehydration. After repeating this operation twice, the aqueous solution of ferrous pyrophosphate was dewatered with a filter press, the breath cake was dried with a paddle dryer, and ferric pyrophosphate powder was prepared using a dry mill. I do. The second slurry of pyrophosphoric acid used in the present invention is not dried and powdered as described above, and may be used in the form of a slurry (bi-ferric phosphate solution).

After the specific surface of the second pyrophosphate powder used as a raw material of the present invention by the nitrogen adsorption method (BET method), the range is preferably 3 nfZg to 5 OniZg. If the specific surface area is less than 3 nf, there will be a problem with long-term stability in liquid foods such as milk, and if it exceeds 5 Onf / g, the cohesive force of the ferric pyrophosphate powder will decrease. It becomes so strong that its dispersion is difficult.

Next, a mixed slurry of at least one selected from the group consisting of the above-mentioned calcium agent and ferric pyrophosphate, PGA, and water is prepared. This preparation method is roughly classified into the following three methods (a), (a), and (ii). Any of these methods may be employed or may be used in combination.

(A) A water suspension of a food additive comprising a calcium agent and / or ferric pyrophosphate and water is powdered and / or powdered by a chemical dispersion method, a physical method using a pulverizer and / or a disperser. Or, after dispersion treatment, add PGA.

After the dispersion treatment, PGA is added, and the mixture is further ground and Z or dispersed by a physical method using a pulverizer and Z or a disperser.

In the above methods (a), (a) and (ii), favorable conditions for preparing a calcium agent and / or a mixed slurry of ferric pyrophosphate, PGA and water include: a calcium agent in the mixed slurry; It is necessary to add 1.5 to 40 parts by weight of PGA with respect to 100 parts by weight of Z and iron or iron agent.When liquid food such as yogurt is taken into consideration, Preferably, 1.5 to 30 parts by weight, more preferably 5 to 15 parts by weight of PGA is added.

(r) 0, 0 4≤M <0.3

If the added part by weight of PGA is less than 1.5 parts by weight, even if the weight (volume) average diameter in the particle size distribution of the calcium agent and / or the iron agent in the mixed slurry is adjusted to be very fine, the mixed slurry of these , Or a calcium and / or iron powder obtained by dry-pulverizing the mixed slurry, for example, when added to foods such as juice, yogurt for drinks and drinks, calcium and Z in foods If the iron preparation has poor stability over time and is remarkable, it will aggregate and settle at the bottom of the food container within 24 hours. -If the added PGA exceeds 40 parts by weight, the mixed slurry If the calcium and Z or iron powders obtained by dry-pulverizing the mixed slurry are added to foods such as juse and drink-type yogurt, the degree of product quality will increase and the texture will increase. Unfavorable and significant

Also, for example, when a mixed slurry or a calcium and / or iron powder obtained by dry-pulverizing the mixed slurry is used for food such as set-type yogurt,? If the added weight of 08 is less than 1.5 parts by weight, or if the added weight of PGA exceeds 40 parts by weight, it is not possible to obtain a structurally good product.

The weight (volume) in the particle size distribution of the calcium agent and / or the iron agent in the mixed slurry is preferably in the range of 0.04 to 0.8 um. If the average diameter is larger than 0.8 m, sedimentation is liable to occur.Therefore, these mixed slurries, or calcium and / or iron powders obtained by dry-pulverizing the mixed slurries, are used for food applications that can be stored for a long time. Cannot be used.

. The method for adjusting the weight (volume) average diameter in the particle size distribution of the calcium agent and / or agent in the mixed slurry to 0.8 zm or less is described above.

By drying and mixing the mixed slurry of the calcium agent and Z or iron agent, PGA and water prepared as described above into powder, the calcium agent for food addition and the iron or iron agent powder of the present invention is prepared.

There is no particular limitation on the drying of the mixed slurry, but it is preferable that the drying is performed in a very short time from the viewpoint of preventing the deterioration of the hydrophilic emulsifier. From this viewpoint, the drying is performed by using a spray dryer, a ceramic medium, or the like. It is desirable to use a droplet spray dryer such as a slurry dryer or the like in a heated and fluidized state.

The resulting calcium phosphate and / or iron agent slurry and powder may be added directly to the milk and stirred vigorously for 81 to disperse the calcium phosphate and / or iron agent in the milk and then inoculated with lactic acid bacteria.

In calcium and / or iron-enriched milk prepared by these methods, the amount of calcium and / or iron removed by the clarifier is reduced by the amount of calcium and / or Z or iron slurry and powder prepared by conventional methods. Significantly less than in the case of adding.

That is, in milk, yogurt, and juices to which a calcium agent and / or a slurry for food additives prepared by the method of the present invention and / or a powder have been added, calcium carbonate, calcium phosphate and / or pyrophosphate secondary acid are contained. Iron is kept very stable.
