Abstract
Abstract Method for making a mixture-type product by preparing a pumpable slush to contain a portion of the product ingredients and then mixing the slush with other product ingredients. Where product temperature control is important, e.g. where the separate mix contains an ingredient which tends to be unstable at elevated temperatures, the slush also serves a cooling and stabilizing function. The slush is prepared by supercooling an aqueous solution of water-soluble product ingredients. For example, water, salt and sugar are used in the manufacture of a food product, dough, and a slush is prepared containing the salt and sugar. Other ingredients of the dough, including a leavening agent which is not stable at the processing temperature and would tend to leaven the dough, are blended as a separate mix. The slush is added to the separate mix and mixed in, resulting in cooling the product below the leavening agent stability temperature while also adding salt, sugar, water and ice (which melts to become water) as ingredients for the dough. The aqueous slush product can be prepared to have a low dissolved solvents content for dietetic foods such as a dietetic drink. The product is prepared as a mixture of particulate ice, water and a small amount of freeze point depressant material containing no more than a low level of normally solid dissolved material commonly referred to as "solids". The freeze point depressant material can be a soluble inorganic salt, a monosaccharide, etc., and containing a small amount of an organic polar solvent which is liquid at the slush temperature.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
166 words
A method for making dough containing water and a solid water-soluble ingredient selected from the class consisting of salts, sugars, sorbitol, water-soluble flavoring ingredients and mixtures thereof and a leavening agent while suppressing an exothermic reaction of the leavening agent, which method comprises preparing a first mixture of water and at least a portion of said water-soluble ingredient with said water-soluble ingredient being in an amount sufficient to function as a freeze point depressant in said mixture, supercooling said first mixture to a temperature below 32° F. in its freezing point range with agitation until ice crystals grow to a sufficient size to form a flowable slush of distinct ice crystals in an aqueous solution of the water-soluble freeze point depressant ingredient, preparing a second mixture containing the leavening agent and other dough ingredients and mixing the flowable slush with the second mixture to provide a dough product, whereby said flowable slush chills the dough to a temperature sufficiently low to maintain the leavening agent inactive.
Claim 2
Independent Claim
166 words
A method for making dough containing water and a solid water-soluble ingredient selected from the class consisting of salts, sugars, sorbitol, water-soluble flavoring ingredients and mixtures thereof and a leavening agent while suppressing an exothermic reaction of the leavening agent, which method comprises preparing a first mixture of water and at least a portion of said water-soluble ingredient with said water-soluble ingredient being in an amount sufficient to function as a freeze point depressant in said mixture, supercooling said first mixture to a temperature below 32° F. in its freezing point range with agitation until ice crystals grow to a sufficient size to form a flowable slush of distinct ice crystals in an aqueous solution of the water-soluble freeze point depressant ingredient, preparing a second mixture containing the leavening agent and other dough ingredients and mixing the flowable slush with the second mixture to provide a dough product, whereby said flowable slush chills the dough to a temperature sufficiently low to maintain the leavening agent inactive.
Claim 3
Dependent Claim
41 words
The method of claim 1 wherein said first mixture contains from about 0.01 to 0.2 weight percent carboxymethlylcellulose and from about 0.1 to 5 weight percent propylene glycol sufficient to disperse the ice particles uniformly throughout the solution under gentle agitation.
Claim 4
Independent Claim
292 words
A method for making dough containing water and a solid water-soluble ingredient selected from the class consisting of salts, sugars, sorbitol, water soluble flavoring ingredients and mixtures thereof and a leavening agent while suppressing an exothermic reaction of the leavening agent, which method comprises preparing as a first mixture a liquid, pumpable and gravity pourable aqueous slush having no overrun and consisting essentially of an aqueous phase containing from about 25 to about 75 percent by volume of individual ice particles having a size in the range of 1/32 to 1/16 inch and having uniform solid ice composition or construction throughout, said individual ice particles individually being nonagglomerated and with respect to each other being nonagglomerating and uniformly dispersed throughout the aqueous phase under gentle agitation at any temperature between the freezing point of the aqueous phase and the melting point of the of the ice particles at about 32° F., said aqueous phase containing a portion, at least about 0.1 percent by weight, of the water-soluble ingredient with said water-soluble ingredient being in an amount sufficient to function as a freeze point depressant in said mixture and sufficient to retain the ice particles in an unmelted condition within the water phase so that the product can be stored under gentle agitation at a temperature below 32° F., the amount of freeze point depressant also being sufficient to achieve the uniform dispersion of the ice particles in the water phase, preparing a second mixture containing a leavening agent and the remainder of the other ingredients necessary for forming the dough and mixing the flowable slush with the second mixture to provide a dough product, whereby said flowable slush chills the dough to a temperature sufficiently low to maintain the leavening agent inactive.
