The extruder process conditions use a Specific Mechanical Energy input of 300 to 550 watt hours per kilogram of material fed to the extruder; a Residence Time Distribution of from about 175 to 400 seconds; a Shear Rate of 65 to 140 reciprocal seconds; and a Peak Temperature of 230.degree. F. to 270.degree. F.

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.

Abstract: The invention relates to a process for preserving the color and texture of vegetable pasta, wherein the color of the vegetable pasta is derived from chlorophyll-containing vegetable matter added to alimentary paste at a pH above 7.0. The color preservation is enhanced by the presence or addition of a cation selected from the group consisting of magnesium, zinc, copper, calcium, and aluminum cations.

Abstract: An aseptically packaged, liquid, non-dairy coffee whitener which is shelf-stable for several months, and a process for preparing it, are provided. The coffee whitener comprises water, vegetable fat, an edible emulsifier system, a milk protein, salt, and other optional ingredients. The process comprises performing an ultra-high temperature sterilization treatment on a mixture comprising water, heated vegetable fat, an edible emulsifier system, and milk protein; cooling; homogenizing; and further cooling and packaging the resulting emulsion in an aseptic container under aseptic conditions. The product is shelf-stable for several months before opening and is stable against browning under refrigeration conditions for up to four weeks after opening. Browning is avoided by the absence or substantial absence of any reducing sugar in the product.

Abstract: A two-stage process for producing a cheese-flavored substance is claimed. A flavor development medium is fermented with a source of lipase/protease; the source of lipase/protease is inactivated and the flavor development medium is fermented by at least one lactic acid-producing microorganism which is thereafter inactivated. The source of lipase/protease is preferably a microorganism, especially Candida lypolitica ATCC 20234. The cheese-flavored substance produced by the process and foods containing the cheese-flavored substance produced by the process are also claimed.

Abstract: A portable chuck for dispensing under tension a roll of wrapping material wound about a tubular core is disclosed herein. The portable chuck includes an expandable spindle insertable within one end of the tubular core, and a handle for selectively expanding the spindle so as to create a braking force between the outside surface of the expandable spindle and the inside surface of the tubular core. The chuck is formed from first and second chuck pieces, each of which includes a semi-cylindrical spindle portion, collar, and handle portion. The fulcrum means is disposed between the first and second adjacent chuck pieces above the collar of each for allowing a relative rocking motion between the first and second adjacent chuck pieces, whereby the spindle portions are drawn away from one another at a mechanical advantage as the handle portions are manually squeezed toward one another.

Abstract: A premoistened towelette or wiper type paper product having high wet strength when stored in an acidic pH medium and during usage and lower wet strength when immersed in a neutral or alkaline pH medium for disposal in conventional sewage systems comprising a non-woven fibrous web which is treated with an improved polymeric binder comprising a copolymer of glyoxal and polyvinyl alcohol which maintains high wet strength when stored for sustained periods of time in acidic pH wetting medium conventionally used for external cleansing of the human body and during usage and yet which will readily break-up during flushing. 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.

An improved variable flavor chewing gum composition containing a delayed release flavorant of the invention is also disclosed.
