Description

Dry product containing high fat

The present invention relates to a dried product containing high fat and oil containing 50% to 90% fat and oil and containing insoluble protein having a shape.

The drying method of fats and oils has been studied conventionally, and a technique of adding an excipient to fats and oils called powdered fats and powdering with a spray dryer is known, and is widely spread mainly in the food industry. .
Various techniques are known for including a high content of fats and oils in a dried product. For example, a method of adsorbing fats and oils on arabinogalactan (Patent Document 1), a method of emulsifying oils and fats, adding dietary fiber and drying to powder (Patent Document 2)
However, in any of the above-mentioned methods, what is manufactured is powdered, and there is no high-fat containing fat-containing drying material having a shape reminiscent of fats and oils, and technical studies are still being conducted.

Japanese Patent Laid-Open No. 5-64544 JP-A-5-137506

The present invention has been made in view of the above circumstances, and its purpose is to provide a high-fat content dry product that contains 50% or more of fats and oils and can take a large form instead of powder. It is to be.

As a result of intensive studies, the inventor prepared an oil-in-water dispersion in which fats and oils were dispersed in a mixed solution of protein and water, and then carried out a drying step to remove moisture and stabilize the oil. It was found that a dried product could be obtained, and the present invention was basically completed.
Thus, the high fat and oil-containing dry product according to the first invention contains protein and fat and oil, and the fat content is 50% to 90% (preferably 60% to 90%, more preferably 70 to 90%). 90%), the size of the dried product passing through a sieve having a mesh size of 1.0 mm is 50% or less, and is insoluble in water.
At this time, the particle size of the fats and oils in the dried product is 1 μm to 100 μm (preferably 1 μm to 50 μm, more preferably 1 μm to 30 μm).
Whereas the powdered fats and oils pass through a sieve having an opening of 1.0 mm, the obtained high fat and oil-containing dried product has a thickness of 1.0 mm or more of 50% or more, preferably 60% or more, more preferably 70% or more. It is like that. Further, the product of the present invention can take a large form such as a granular shape or a die shape, unlike the conventional powdered fats and oils.

The protein is preferably at least one selected from the group consisting of soy protein, egg protein, milk protein, gelatin, collagen, and fish protein. Examples of soy protein include isolated soy protein and concentrated soy protein, and are not particularly limited, but are preferably isolated soy protein. The whey protein includes whey protein, milk casein, and caseinate, and is not particularly limited, but is preferably whey protein or caseinate.

The collagen includes collagen derived from cow, pig, chicken, fish skin or bone, and is not particularly limited, but is preferably derived from cow, pig, chicken, fish skin.

Depending on the type of protein, thickening polysaccharides can be used for the purpose of adjusting production suitability and oil particle size. The thickening polysaccharide is not particularly limited. For example, guar gum, xanthan gum, carrageenan, mannan, locust bean gum, gellan gum, tamarind gum, pectin, sodium alginate, curdlan, gum arabic, tara gum, carboxymethyl cellulose Etc. can be illustrated. Preferred are guar gum, xanthan gum and carrageenan. Examples of carrageenan include lambda, copper, and iota. Although not particularly limited, lambda is preferable. ADVANTAGE OF THE INVENTION According to this invention, a high fat and oil containing dried product can be provided, without using a thickening polysaccharide. However, although the detailed reason is unknown, it was confirmed that the thickened polysaccharides were used in combination, so that the fat and oil particles in the dried product had a tendency to have a small particle size and improved production suitability. For this reason, a more stable high fat and oil containing dried product can be provided by using a thickening polysaccharide together.

The said fats and oils are not specifically limited, Any oils and fats may be used, and one kind or two or more kinds may be combined from the viewpoint of flavor and price. Vegetable oil or animal oil may be used, and the melting point is not limited. Oils and fats for food may be used, and industrial oils and fats may be used.

Next, embodiments of the present invention will be described with reference to the drawings. However, the technical scope of the present invention is not limited by these embodiments, and various forms can be made without changing the gist of the invention. Can be implemented.
<Test 1: Production of high fat and oil-containing dried product with difference in protein and presence / absence of thickening polysaccharide> Measure water in a 500 ml metal measuring cup, add protein and stir, then heat to 50 ° C with thermo controller It heated at 50 degreeC in the set hot water bath (protein aqueous solution preparation process). Stir for 2 minutes with a homomixer TK ROBO MICS (TOKUSHU KIKA KIGYO CO.LTD), add rice oil in small portions and stir for 4 minutes 30 seconds until uniform, to obtain an oil-in-water dispersion (dispersion) Adjustment process).
When the thickening polysaccharide was added thereto, the thickening polysaccharide was added little by little and stirred for 1 minute to obtain a dispersion using the thickening polysaccharide in combination. 20 g of these dispersions were formed into a Teflon (registered trademark) sheet into a sheet and subjected to microwave heat drying (MD) (drying step). The MD conditions were 1.6 kW and 3.3 min. This was cut 5 mm × 5 mm in length and width to obtain a dry product containing granular high fat.

The proteins used in the test were soy protein, whole egg powder, collagen, whey protein, gelatin, and egg white powder. The thickening polysaccharides used in the test were guar gum, xanthan gum and carrageenan (lambda). Table 1 shows the combination of examination of high fat and oil-containing dried products and experiments using thickening polysaccharides in combination with each protein. Table 2 shows the results.
Moreover, Table 3 examined the kind of thickening polysaccharide. Table 4 shows the results. Table 5 shows melting points of various fats and oils.
According to the results of Examples 1 to 5, each protein contained 70% or more of fats and oils, and a stable dry product could be provided (in the present specification, all examples are within the scope of the present invention). include). Moreover, by using a thickening polysaccharide together from Examples 4 and 5, the moldability was improved and the production suitability was improved.
From Examples 6, 7, and 8, it was confirmed that the same effect was obtained even when the thickening polysaccharide was other than guar gum.
The test which substituted the rice oil of Example 1 for the various fats and oils shown in Table 5 was done. For extremely hardened oil, the temperature setting of the hot water bath was set to 80 ° C. In any of the fats and oils, a high fat and oil-containing dried product could be obtained.

<Confirmation of oil particle diameter by microscope>
The range of the fat and oil particle diameter is determined by performing microscopic observation. However, the high fat and oil-containing dried product may be difficult to perform microscopic observation of the fat and oil particle diameter. Therefore, the fat and oil particle diameters of the dough before drying that could be observed under a microscope and the dried product containing high fat and oil after drying were confirmed.
The method for measuring the fat and oil particle diameter is to take a photograph at a point where the fat and oil can be confirmed with a microscope, measure the diameter of ten points that is considered to be the average of the fat and oil particle size, and determine the range between the minimum and maximum values. It is shown in the table as the range of oil particle diameter.
Comparing the micrograph before drying (FIG. 1) and the micrograph after drying (FIG. 2), it was found that there was no change in the fat particle diameter due to drying. From this, it was confirmed that the fat and oil particle diameter in the dried product was obtained with the result of microscopic observation of the fat and oil particle diameter in the preparation liquid before drying.
Moreover, the result of having measured the fat particle diameter in the adjustment liquid before drying in Example 3 (FIG. 3) and Example (FIG. 4) was made into the range of the fat particle diameter. Although not shown in the figure, when other proteins (soybean protein, whole egg powder) were used, dried products having a fat and oil particle size of about 1 μm to 100 μm were observed.

<Effects of differences in blending amount of fats and oils>
Table 7 shows the composition of the dried product containing high fats and oils. The oil content (%) in the product was calculated from the solid content and lipid content of each raw material in Table 6.

Example 7 was able to produce a dry product containing high fat and oil containing 90.1% rice oil in the dry product. Further, Comparative Example 1 was not suitable for production and supply as a dry product because the oil-off was confirmed during the preparation of the preparation solution. Although the comparative example 2 can be manufactured as a dry product, the fat and oil content was 50% or less. In this case, it did not correspond to the high fat and oil-containing product of the present invention.

<Examination of other protein materials 1>
As another protein material, a dried product containing high fats and oils was produced using ground beetle surimi (fish meat protein).
After adding 3g of salt to 100g of pollock surimi (fish meat protein), salting it with a food processor, adding 85g of rice oil in small portions and uniformly dispersing it into a 1.5cm diameter deposit, then microwave Heat-dried to produce a dried product containing high fats and oils. The fat content in the dried product was 75.2%.
Table 8 shows the composition of the dried product containing high fats and oils. The oil content (%) in the product was calculated from the solid content and lipid content of each raw material in Table 9. Table 10 shows the results.
