Application of soybean emulsion composition to soybean-derived raw material-containing food or beverage
The present invention addresses the problem of providing a soybean-derived raw material-containing food or beverage that improves problems with flavor and physical properties, such as the grassy smell caused by soybean raw materials, and markedly improves product quality, in a soybean-derived raw material-containing food or beverage using conventional soybean raw materials such soymilk or tofu. Provided are a milk-substitute composition, and an egg-yolk substitute composition, etc., characterized by including a soybean emulsion composition having a protein content relative to dry material of at least 25 wt %, a fat content (as a chloroform/methanol mixed solvent extract) relative to the protein content of at least 100 wt %, and an LCI value of at least 55%. Also provided are a variety of soybean-derived raw material-containing food and beverages using these compositions.
1. A soybean extracted food or beverage emulsion which is obtained by adding water to a fat containing soybean comprising a fat at a content of 35 wt % or more in terms of dry basis and having a Nitrogen Solubility Index in the range from 20 to 77 to prepare a suspension liquid, and then subjecting the suspension liquid to a solid-liquid separation to transfer neutral lipid and polar lipid to an insoluble fraction, and then removing a soluble fraction comprising protein and sugar, and then recovering the insoluble fraction which comprises the soybean extracted food or beverage emulsion, wherein the soybean emulsion has a protein content of 25 wt % or more in terms of dry basis, a fat content 100 wt % or more relative to the protein content in terms of dry basis, a fiber content of 10 wt % or less, a lipophilic proteins content index value of 55% or more, and contains a denatured lipophilic protein.
2. An acidic soybean material obtained by acidification of the soybean extracted food or beverage emulsion of claim 1 with a lactic acid bacteria.
3. A dairy product substitution or a fermented dairy product substitution comprising the soybean extracted food or beverage emulsion of claim 1 or the acidic soybean material of claim 2 .
4. The soybean extracted food or beverage emulsion of claim 1 , which has an lipophilic proteins content of 60% or more.
5. The soybean extracted food or beverage emulsion of claim 1 , which comprises a fat at a content of 120 to 250 wt % relative to the protein content.
6. An egg yolk substitute composition comprising the soybean extracted food or beverage emulsion composition of claim 1 .
7. An egg yolk substitute composition comprising the soybean extracted food or beverage emulsion of claim 2 .
8. An egg yolk substitute food comprising the egg yolk substitute composition of claim 6 as a partial or complete substitute for an egg yolk.
9. A processed soy food comprising the soybean extracted food or beverage emulsion composition of claim 1 as a part or all of a soybean raw material of the processed soy food.
10. A processed soy food comprising the soybean extracted food or beverage emulsion composition of claim 2 as a part or all of a soybean raw material of the processed soy food.
11. A composition for reducing serum cholesterol or improving renal function, comprising the soybean emulsion composition of claim 1 .
12. A composition for reducing serum cholesterol or improving renal function, comprising the soybean emulsion composition of claim 2 .
13. A food comprising the composition for reducing serum cholesterol or improving renal function of claim 11 .
