Description

Acidic oil-in-water type emulsified food

Technical Field

The present invention relates to an acidic oil-in-water type emulsified food, and more particularly to an acidic oil-in-water type emulsified food containing an edible oil and fat, egg white, a nonvolatile acid and modified starch.

Background

Conventionally, in japan, acidic oil-in-water type emulsified foods such as mayonnaise are distributed in the form of being filled in flexible containers such as squeeze containers. On the other hand, in other than japan, acidic oil-in-water type emulsified foods are distributed in a form filled in a hard container such as a bottle. Many acidic oil-in-water type emulsified foods filled in a rigid container are scooped out with a spoon or the like and used. Therefore, in order to facilitate scooping, an oil-in-water type emulsion food having low adhesiveness and a certain degree of hardness is required.

For example, patent document 1 describes an acidic oil-in-water type emulsified seasoning having a certain degree of hardness in order to suppress dehydration when used for salad. Patent document 1 proposes to adjust the oil content in an acidic oil-in-water type emulsified seasoning to 65 to 70 mass% and to adjust the solid content concentration of an aqueous phase to 20 to 50%. However, when the content of the oil or fat is small, it is difficult to produce an acidic oil-in-water type emulsified food having relatively hard physical properties.

When the pH of the acidic oil-in-water type emulsified food is within the above range, the preservation property can be improved by suppressing the generation of microorganisms in the acidic oil-in-water type emulsified food, and the flavor of the acidic oil-in-water type emulsified food can be well balanced. The pH of the acidic oil-in-water type emulsified food was measured by a pH meter (desk type pH meter F-72, manufactured by horiba, Ltd.) at a product temperature of 20 ℃ under 1 atmosphere.
