  • Patent number: 4751097
    Abstract: A method of making improved liquid smoke products, having increased staining capability, enhanced storage stability, and a reduced concentration of materials separable upon dilution of the liquid smoke. The method effectively removes precipitable tar-like materials from liquid smoke by a prompt and rapid cooling, or "chilling," of the liquid smoke after its production, followed by timely separation of the supernatant from the precipitated phase.

  • Patent number: 4054679
    Abstract: A process for preparing a soy protein product having a high concentration of both solubilized carbohydrates and soluble protein, and being characterized by substantial freedom from bacterial activity, absence of objectionable beany flavor, light color, suitability for use in food preparations for human consumption, and enhanced palatability, wherein soybean material in the form of an aqueous slurry is first adjusted to an acid pH in the isoelectric range for the protein content of the material treated, or from about pH 3.5 to about pH 5.5, then subjected to steam injection to bring the temperature of the treated mass to the range of from about 225.degree. to about 400.degree. F, maintaining such temperature for a short time period, preferably from about 3 to about 30 seconds, to destroy viable bacteria and to solubilize carbohydrates. Residual steam is flashed, together with volatile constituents including objectionable flavor elements present in the soybean material.
