Abstract
A fat-extractant composition comprises by weight 3-6,5 parts of an ester or ether of a polyoxyethylene having a minimum of 5 and an average of 16 oxyethylene groups per molecule with, respectively, an aliphatic or heterocyclic acid having 12-30 carbon atoms per molecule or an aliphatic alcohol having at least 12 carbon atoms in the chain, 1-5,5 parts of ethylenediamine tetraacetic acid or a soluble salt of gluconic acid and 1-5,5 parts of an alkaline alkali metal salt. The extractant preferably also comprises up to 5,5 parts of urea as an anticoagulant and up to 4 parts of a buffering agent such as disodium orthophosphate. The preferred alkali metal salt is sodium carbonate and the preferred gluconate is sodium or potassium gluconate. The extractant may be in granular form or dissolved to form a solution. The extractant may be prepared by grinding and screening individually urea, sodium phosphate, EDTA and sodium carbonate, mixing and stirring in the polyoxyethylene ester component until the product cakes, breaking and screening. This material may then be restirred, broken and screened and allowed to cure at room temperature. The cured product dissolves in water, initially as a colloid. When used in extracting milk, methanol may also be present in the extractant. In order to extract the fat from materials such as milk and cream, meat and meat byproducts, e.g. tankage and meat scraps, soya beans, peanuts, cotton seed and other oils and oil-bearing seeds, processed products such as evaporated or condensed milk, cheese, ice cream, frozen desserts, salad dressings, potato chips and fried corn meal products, the extractant is added in the presence of water and the mixture heated to 100 DEG C. until stratification into fat, surfactant and aqueous medium (in downward sequence) takes place, and then adding water and cooling, e.g. to 55 DEG -60 DEG C., until the strata are rearranged, into the downward sequence fat, aqueous medium and surfactant. If the added water is cool, the last two steps are accomplished simultaneously, but they may be performed in either order. The pH is preferably maintained at 7,5-9,5. In treating milk or cream which has soured it may be desirable to add aqueous citric acid before the extractant.
