Abstract: The invention is directed to a process for preparing reduced calorie, essentially lactose free, artificially sweetened yogurt. By utilizing ultrafiltration and enzymatic hydrolysis to reduce the lactose content, and by the addition of low calorie sweeteners, a yogurt product is produced with 60-70 calories per six ounces of product. Because the lactose level is reduced to less than 0.1% by weight, the product is amenable to lactose-intolerant individuals.

Abstract: The invention relates to the use of lithium ion-generating alkalizing agents in resole binder compositions useful for bonding aggregate materials to form refractory articles. Use of lithium-ion generating alkalizing agents produce resole resin binder compositions which, when cured by an ester functional curing agent, exhibit tensile and compression strengths superior to strengths obtained from compositions using sodium ion-generating or potassium ion-generating alkalizing agents.

Abstract: A method for bonding lignocellulosic material under heat and pressure together with steam and a gaseous ester wherein a mat of lignocellulosic material with a curable aqueous alkali solution of a phenol-formaldehyde resole binder is compressed between a pair of heated press platens to a first intermediate density and thickness, and condensable steam is injected into the mat through openings in said platens; the mat is then further compressed to a final density and thickness; and an ester in gaseous form is injected into said mat to cure a portion of the binder. Following the gaseous ester injection, the mat may be further injected with high pressure steam to cause further cure or elimination of uncured formaldehyde. A vacuum or exhaust is optionally applied to the mat through the platen opening to remove excess steam and other vapor, and the press is opened to remove the board formed from the mat.

This instant invention also comprises a method of treating non-woven fibrous webs with the improved glyoxalated polyvinyl alcohol copolymer binder and drying prior to wetting in an acidic, e.g. boric acid medium.

Abstract: The invention provides an encapsulated flavorant composition for use in food and other compositions intended for introduction into the mouth. This composition is prepared by the steps of forming an emulsion of flavoring agent in a partially hydrophilic matrix material comprising gelatin, a natural gum or albumin and plasticizer; drying the emulsion to a solid matrix; grinding to a solid base powder; and then coating the base powder with a water insoluble material which will prevent elution of flavor from the base powder and will not immediately dissolve under the hydrolytic condition of the mouth yet which, when chewed, or otherwise worked in the mouth, will give a substantial flavor "burst" and sustained flavor release as the hydrophilic base powder matrix is wetted in the mouth. The encapsulated flavorant composition may be used in chewing gum, candies and other foods, toothpaste, chewing tobacco and snuff.

Abstract: Phenol-formaldehyde resin powder capable of both heat softening and fast-cure is produced by spray drying a blend of resole and novolac prepolymers. The powder, when mixed, heated and pressed with wax-coated wood chips, flows and cures to form a superior, bonded flake waferboard.

The composition is comprised of montan wax, an emulsifier, silicone oil, amino silicones, finely-divided abrasive, water, volatile aliphatic hydrocarbon liquid, and optionally, pigment. The improvement comprises using a volatile aliphatic hydrocarbon liquid having an evaporation rate approximately three to five times faster than the evaporation of water.

Abstract: A method for preparing a controlled, delayed release encapsulated flavorant composition for use in chewable confections prepared by the steps of forming an emulsion of flavoring agent in a partially hydrophilic matrix material comprising gelatin, a natural gum and plasticizer; drying the emulsion to a solid matrix; grinding to a solid base powder; and then coating the base powder with a water insoluble material which will prevent elusion of flavor from the base powder and will not dissolve under the hydrolytic condition of the mouth to give a delayed flavor release and yet which, when chewed, will give a substantial flavor "burst" and sustained flavor release as the hydrophilic base powder matrix is wetted in the mouth. An improved variable flavor chewing gum composition containing a delayed release flavorant of the invention is also disclosed.
