  • Patent number: 4748038
    Abstract: The invention relates to a method of producing a bland tasting full fat soy flour meal or grits (PSM) wherein the soybeans either whole or split are treated with live steam or water under atmospheric pressure at temperatures ranging between 85.degree. to 100.degree. C. for 21/2 to 20 minutes or for an equal or shorter period under steam pressure in excess of atmospheric pressure, the combination of time and temperature under steam pressure in excess of atmospheric pressure being such that the degree of blandness in the resultant PSM is about equivalent to the blandness which results in the stated treatment under atmospheric pressure.

  • Patent number: 4683141
    Abstract: Dehydrated vegetable products having relatively high moisture content and high stability are produced by dehydrating vegetables to the extent where 20-85% of the moisture has been removed; adding to the partially dehydrated vegetables a predetermined volume of a solution containing a known quantity of at least one water activity-controlling solute, the quantity of the solution being such that it is totally absorbed by the vegetables, and the vegetables are then dehydrated to a predetermined final level of moisture and/or water activity. Highly stable vegetable products having salt contents of 3-15% sugar contents of 0-15% and moisture contents of 6-25%, with a water activity preferably in the range of 0.45-0.85 at 20.degree.

  • Patent number: 4671815
    Abstract: This invention relates to salts of oxyalkylated amino compounds which render normally water insoluble components such as biocides, soluble in water and thereby improving their usefulness and effectiveness. These amino compounds render biocides such as methylene bis(thiocyanate) (MBT) and/or bis(trichloromethyl) sulfone (BTMS) water soluble. The soluble forms of these biocides afford more predictable, consistent and effective biocidal results when applied to systems contaminated with microorganisms such as bacteria, fungi, algae, molds, and certain yeasts and thus offer considerable advantages over insoluble, dispersible, emulsified forms of these biocides.

  • Patent number: 4518509
    Abstract: This invention relates to particulate compositions containing chemical additives for petroleum systems. The particulate compositions when added to petroleum systems gradually dissolve over a period of time, releasing the chemical additive, so as to improve the petroleum system. The use of such particulate compositions has an advantage over the use of the chemical additive itself since the pellets give longer residence time and sustained treatment over a longer period.
