  • In-line dewaxing of edible vegetable oils
    Patent number: 4981620
    Abstract: A method for the combined in-line bleaching and dewaxing of vegetable oils which includes the steps of bleaching the vegetable oil with a sufficient amount of bleaching clay and filter aid at a temperature of about 80.degree.-130.degree. C. for about 15-60 minutes, followed by rapid cooling of the bleached vegetable oil containing the bleaching clay, to a temperature of about 0.degree.-15.degree. C. for about 15 minutes-4 hours to thereby dewax the vegetable oil. The spent bleaching clay, waxy material and other impurities in the vegetable oil are then seaparted at low temperatures of about 0.degree.-20.degree. C., by such means as filtration, to thereby recover the bleached and dewaxed vegetable oil.

  • Method for regulating plant growth
    Patent number: 4813997
    Abstract: A process for increasing the rate of plant growth. Plants are treated with one or more acids, which are condensation products of glycolic and/or L-lactic acid. These acids also increase the concentration of chlorophyll, increase the rate of new plant formation when plants are propagated by tissue culture, decrease the amount of added nutrients required for plant growth, and protect plants against the toxic effects of salts. Certain of the acids are useful for increasing the rate of root formation in the plant.
