  • Patent number: 6042865
    Abstract: The present invention relates to a food foaming agent composition which imparts good taste and good texture in the mouth to the food product and imparts good foaming property and good foaming stability. This food foaming agent composition is characterized in that (1) the taste of the product is not deteriorated regardless of excellent foaming property and excellent foaming stability because it contains a glycerin fatty acid ester as an emulsifier but does not contain a sorbitan fatty acid ester, a propylene glycol fatty acid ester and a sucrose fatty acid ester. More specifically, the food foaming agent composition is characterized in that (2) a glycerin saturated fatty acid monoester and a polyglycerin saturated fatty acid ester are used as the glycerin fatty acid ester in a weight ratio within the range from 1:0.

  • Patent number: 5998396
    Abstract: The present invention discloses oil solubilized solutions and foods containing phystosterols containing sitosterols with improved stability, for better absorption of those phytosterols into the body through their oil solubilization, as well as a process for their production; the oil solubilized solutions and foods of the invention are characterized by addition of vitamin E and emulsifiers to sitosterol-containing plant sterols to render the plant sterols soluble in oil, and particularly by extraction of the sitosterol from natural plant components, either alone or as a composition containing other phytosterol components, and by inclusion of vitamin E, emulsifiers which are liquid at room temperature, and glycerin esters of medium chain fatty acids of 6-12 carbon atoms; the process for producing oil solubilized plant sterols according to the invention is characterized by adding vitamin E and emulsifiers to phystosterols containing sitosterols to render the plant sterols soluble in oil.
