JP4397259B2 - Flavored oil and fat and method for producing the same - Google Patents

Description

  The present invention relates to edible fats and oils to which the flavor and richness of the flavor material itself are imparted and a method for producing the same.

  Most edible oils refined by conventional methods are tasteless and odorless except sesame oil, olive oil and milk fat. Conventionally, fats and oils called flavored fats and oils (or flavored fats and oils) obtained by flavoring such edible refined fats and oils are known. As a method for producing this flavor oil and fat, the flavor material is directly heated with edible oil at a high temperature of 120 to 180 ° C. while vigorously stirring and contacting, and the flavor component of the flavor material is transferred into the edible oil and fat. For example, a method for producing a flavored oil and fat (Patent Document 1) for collecting an oil phase after adding a cut or ground vegetable to a vegetable edible oil and holding at 110 ° C. to 160 ° C. for 60 minutes or less, and an edible oil and fat Various methods have been proposed, such as a method for producing flavored oils and fats having various flavors by heat-treating a heat-treated product under a normal pressure of a mixture of odorant and a flavor enhancer (Patent Document 2). However, most of the flavored fats and oils produced by these methods are used as seasonings such as Chinese dishes and soups, and are intended to impart a fragrant flavor produced in the processing step. Moreover, the flavor oil and fat obtained by heat-treating the mixture containing fats and oils, the complex of lipid and protein, milk solid content, and water at 80-180 degreeC, and removing solid content and / or a water | moisture content, and its manufacture The method (Patent Document 3) relates to an edible fat and oil limited to the flavor and richness of milk and a method for producing the same, and is not intended for imparting a flavor of milk solids, which is a flavor material. Further, the present invention is different in that a fatty acid is essential as a material constituting the composite and the heat treatment temperature can be lowered.

  In addition, the oil and fat, a complex of organic acid monoglyceride and milk protein, milk solids, and water are mixed, and one or more of fatty acid-degrading enzyme, proteolytic enzyme, and lactose-degrading enzyme are allowed to act on this, followed by degradation treatment An oil-and-fat emulsion (Patent Document 4) containing an enzyme-treated decomposition product has been proposed. In this method, a complex of organic acid monoglyceride and milk protein is used. However, as described above, fatty acid is essential as a material for forming the complex as described above, and fatty acid decomposition treatment and protein decomposition treatment in the present invention. Are different in that they are before preparation of the composite. Furthermore, in Patent Document 4, a raw material containing a complex is mixed and decomposed with a fatty acid degrading enzyme or a proteolytic enzyme to produce a fatty acid, monoglyceride, diglyceride or protein degradation product that is a raw material of the complex of the present invention. However, since the homogenizing means such as an ultrasonic homogenizer is not performed thereafter, the formation and effect of the composite in the present invention cannot be expected.

Until now, flavors obtained by extracting and concentrating flavor components from flavor materials and synthetic flavors have been widely used to impart the flavor of flavor materials themselves to fats and oils. However, in the method of adding these fragrances, flavor components are severely deteriorated by extraction / concentration, and it is difficult to efficiently recover them without changing the original fresh flavor. In addition, the synthetic fragrance has a problem that the flavor is rough, stimulating and sharp, and unlike the present invention, it becomes an artificial fragrance that is not familiar with a natural fragrance.

Yeast, goat, lamb, oral lipase collected from the oral secretion line of the cow, and the like, and at least one of them can be used. Degradation of fats and oils by fatty acid degrading enzymes can be performed according to generally used conditions. That is, with respect to 100 parts by weight of fats and oils, water was added in the range of 0.01 to 50 parts by weight, and the reaction temperature was 15 to 70 ° C, preferably 30 to 50 ° C and decomposed in the range of 0.1 to 120 hours. Thereafter, the enzyme reaction may be stopped by heat treatment. The degree of degradation of fats and oils by fatty acid degrading enzymes is preferably 2 to 90%, more preferably 5 to 50%. If the degree of degradation of fats and oils is less than 2%, the effect of flavor transfer of the flavor material by the complex expected in the present invention may not be obtained, and if it exceeds 90%, it may be difficult to form a complex with protein. is there. In addition, the decomposition degree of fats and oils means the value calculated | required by [{(acid value) / (saponification value)} * 100]. The resulting fat and oil degradation product by the fatty acid degrading enzyme may be used by fractionating fatty acids, monoglycerides and diglycerides, or may be used as degraded fats and oils containing triglycerides.

Specific examples include skim milk powder, whole milk powder, casein, whey, soy protein, wheat protein, egg white protein, egg yolk protein, and the like, and at least one of these is used. These proteins can be degraded with a proteolytic enzyme before producing the complex, and the degree of degradation is particularly preferably 50% or less, more preferably 0.1 to 15%. If the decomposition exceeds 50%, the complex may be difficult to form. The degree of degradation was determined by measuring the amount of degradation by measuring α-amino group by formol titration or the like, and dividing it by the total amino acid content of the protein (%). The proteolytic enzyme used in the present invention is preferably an endo-type protease, more preferably trypsin or papaya, and at least one of these is used. Degradation of a protein by a proteolytic enzyme can be carried out under generally used conditions. That is, the protein is dissolved or dispersed in water in the range of 1 to 15 parts by weight, and the reaction temperature is 15 to 70 ° C., preferably 30 to 50 ° C. and decomposed in the range of 0.1 to 72 hours, and then the enzyme reaction inhibition An appropriate amount of the agent may be used, or the enzyme reaction may be stopped by heat treatment.

  Next, the manufacturing method of the composite used by this invention is demonstrated. First, an aqueous solution of 1 to 50 parts by weight, preferably 5 to 25 parts by weight of protein is prepared with respect to 100 parts by weight of water. At this time, it is preferable to adjust the pH of the aqueous protein solution to a range of usually 6 to 7 in order to effectively bind the fatty acid alone, or the fatty acid, monoglyceride and / or diglyceride, and protein. If the amount of protein is determined, the amount of fats and oils may be adjusted so that the fatty acid alone or the amount containing 10 to 5000 parts by weight of fatty acid and monoglyceride and / or diglyceride per 100 parts by weight of protein is prepared. The heated protein solution was heated to 50 to 70 ° C., and the fatty acid heated to 50 to 70 ° C. alone or an oil containing fatty acid and monoglyceride and / or diglyceride was added and mixed with stirring. The composite is prepared by a homogenizing means such as a sonic homogenizer, a homogenizer, a homomixer, or a mycolloider. If the amount of fatty acid alone or fatty acid and monoglyceride and / or diglyceride added to 100 parts by weight of protein is less than 10 parts by weight, the impartation of flavor to the target oil may not be sufficient, and more than 5000 parts by weight. In systems, the effect may peak. The emulsified form in producing the composite may be any of oil-in-water (O / W), water-in-oil (W / O), and other multiphase emulsified systems. When the complex used in the present invention is used in the form of the aqueous solution thus obtained, it is preferably subjected to sterilization treatment such as UHT from the viewpoint of storage. Although it may be in the form of an aqueous solution, it may be subjected to a drying treatment by means such as spray drying, reduced pressure drying or freeze drying from the viewpoint of handling and storage.

  The blending ratio of these composites in the flavored fats and oils is preferably 0.01 to 10 parts by weight, more preferably 0.1 to 5 parts by weight with respect to 100 parts by weight of the fats and oils in terms of solid content. . If the addition amount is less than 0.01 parts by weight, the effect of the invention may not be obtained, and even if it exceeds 10 parts by weight, the effect may reach its peak.

  The ratio of the water used when manufacturing the flavored fats and oils obtained by this invention has the preferable range of 1-50 weight part with respect to 100 weight part of fats and oils. If the blending ratio of water is less than 1 part by weight, the flavor of the flavor material may not be sufficiently transferred to the oil and fat, and if added over 50 parts by weight, the flavor component will not be transferred effectively and the flavor will be weak There is.

  As a method for producing a flavored oil according to the present invention, a mixture containing a predetermined amount of oil, fat, the composite, a flavor material and water is heated at 30 to 100 ° C. for 5 to 120 minutes. If it is less than 30 ° C., the effect may be difficult to obtain. On the other hand, if it exceeds 100 ° C., a fragrant flavor is produced, and the flavor of the flavor material itself may be impaired. For the heat treatment, a heating and stirring device having stirring blades may be used. For example, a kneader, a kneader, a cooking mixer, or the like may be used. Furthermore, it is preferable to perform homogenization while dehydrating under a reduced pressure of 100 Torr or less during the heat treatment, so that the flavor components can be easily transferred. The degree of dehydration is preferably maintained at 30% or more of the initial moisture content, and if the moisture content is less than 30%, a fragrant flavor may be imparted. Further, as a homogenizing means, an ultrasonic homogenizer, a homogenizer, a homomixer, a mycolloider, or the like may be used. After completion of the heat treatment, the mixture is cooled, and solids and moisture are removed by a separation means such as filtration, centrifugation, and decantation to obtain a flavored oil.

  The flavored fats and oils obtained in this manner can be used to obtain a plasticized fat-like flavored fat and oil through a cooling plasticizer, if necessary, when the fat and oil contains solid fat at room temperature.

  Examples of foods to which the flavored oils and fats of the present invention can be applied include sausages, hamburgers, meat dumplings, soups, dairy products, ice creams, sauces, roux, curry roux, gratin, stews, breads, baked goods, cakes, sponges, cookies, custards , Donuts, mayonnaise, dressings, croquettes, margarines, shortenings, whipped cream, concentrated milk, seasonings and the like.

  Although the addition amount of the flavor oils and fats of this invention changes with applicable foods and cannot be limited, 0.01-90 weight part is preferable with respect to applied food, More preferably, 0.1-20 weight part is added and this invention is added. The effect of the flavor oil and fat can be sufficiently obtained.

An oil phase was prepared by adding 3 parts by weight. On the other hand, 4 parts by weight of skim milk powder, 0.1 part by weight of sodium hexametaphosphate and 0.2 part by weight of sucrose fatty acid ester (HLB11) were dissolved in 55.4 parts by weight of water to prepare an aqueous phase. The oil phase was added to the aqueous phase at 60 ° C., homogenized at 5 MPa after pre-emulsification, UHT sterilized at 140 ° C. for 4 seconds, homogenized again at 10 MPa, and cooled to 5 ° C. to produce a cream. This cream was aged at 5 ° C. overnight and 100 parts by weight of granulated sugar was mixed with 8 parts by weight, and whipped with a mixer to obtain whipped cream.

(Comparative Example 12) Production of whipped cream A cream was produced in the same manner except that the flavored oil of Comparative Example 4 was added instead of the flavored oil of Example 1 used in Example 9, and whipped in the same manner. Whipped cream was obtained.

  Table 7 shows the results of sensory evaluation by 12 panelists. The whipped cream of Example 9 (using the flavored oil and fat of Example 1) felt a strong milky taste, taste and richness, and was clearly different from the cream of Comparative Example 12.

(Example 10) Production of margarine 67 parts by weight of soybean hardened oil (melting point 36 ° C), 10 parts by weight of rapeseed oil, and 5 parts by weight of flavored oil and fat of Example 3 were dissolved by heating, 0.2 part by weight of glycerin fatty acid ester, lecithin An oil phase was prepared by adding 0.2 parts by weight and 0.001 part by weight of β-carotene. On the other hand, 1.5 parts by weight of skim milk powder and 2.0 parts by weight of sodium chloride were dissolved in 14.099 parts by weight of water to prepare an aqueous phase. The water phase was gradually added to the oil phase at 65 ° C. and emulsified, and then rapidly cooled with a scraping-type cooler and stabilized through a kneader to produce a margarine for bread.

(Example 11) Production of margarine Bake margarine was produced in the same manner except that the flavor oil of Example 8 was added instead of the flavor oil of Example 3 used in Example 10.

(Comparative example 13) Manufacture of margarine The attached margarine for bread was manufactured by the same method except having added the flavor oil and fat of Comparative example 7 instead of the flavor oil and fat of Example 3 used in Example 10.

  Table 8 shows the results of sensory evaluation by 12 panelists as margarine for bread. The margarine of Example 11 felt strongly the flavor and richness of fermented milk, and there were many people who answered that it was the most preferable as eight people.

(Example 12) Production of ice cream 10 parts by weight of the flavored oil and fat of Example 5 was dissolved by heating, and 0.2 parts by weight of lecithin was added to prepare an oil phase. Meanwhile, 16 parts by weight of skim milk powder, 8 parts by weight of lactose and 0.2 parts by weight of sucrose fatty acid ester (HLB11) were dissolved in 65.6 parts by weight of water to prepare an aqueous phase. The oil phase was added to the aqueous phase at 60 ° C., and after pre-emulsification, homogenized at 5 MPa, UHT sterilized at 140 ° C. for 4 seconds, homogenized again at 10 MPa, and cooled to 5 ° C. to produce a concentrated cream.

  Next, ice cream was manufactured with the formulation shown in Table 9.

  When the egg yolk is put in the container, add sugar in two portions, stir to smooth, add corn starch and mix well until it becomes whitish. Pour a little warm cream into this, and knead it over low heat until thick. Further, add gelatin that has been softened to dissolve completely, and then filter. It was quickly cooled while being mixed with a whisk while soaking in ice water, and evenly mixed with freshly whipped cream, then cooled in an ice creamer to obtain a hardened strawberry ice cream.

(Comparative example 14) Manufacture of ice cream Concentrated cream was manufactured by the same method except having added the flavor oil and fat of the comparative example 9 instead of the flavor oil and fat of Example 5 used in Example 12. Subsequently, ice cream was similarly manufactured with the composition shown in Table 9.

  Table 10 shows the results of sensory evaluation by 12 panelists. The ice cream of Example 12 felt the refreshing flavor and richness of strawberries, and the number of those who answered that it was preferable was overwhelmingly nine.
