Abstract: A dark-colored freeze dried coffee is produced by using a multi-step process to freeze the coffee extract. The coffee extract is chilled to a temperature at which an ice slush forms. The slushed extract is heated in order to melt some of the slush and subsequently re-chilled. This procedure may be repeated one or more times prior to chilling the extract below its eutectic point and freeze drying the frozen extract.

Abstract: A method for producing dry fruit chips in which starting fruit chips having an adjusted water soluble sugar concentration are freeze-dried to reduce the moisture content to a predetermined moisture content range, the freeze-dried fruit chips are microwave-dried to further reduce the moisture content to a second predetermined range and the microwave-dried fruit chips are vacuum-dried to still further reduce the moisture content to a range suitable for ready eating as snack fruit.

Abstract: A whole body system nutrient material basically of lyophilized and dried mussel meats and body fluids with ascorbic acid (vitamin "C") added. The nutrient material is produced with a coating of ascorbic acid applied to substantially all surfaces of previously dried mussel material cells through immersion of the dried material in fluid containing ascorbic acid in solution in quantity such as to coat mussel material cells inside and out. One solution useful is a water based solution and another is an alcohol solution, both with ascorbic acid that remains as a coating on surfaces. The mussel particulate material, even though it is fine, consists of porous cell clusters having the nucleic components incorporated as part of the inner cell walls. The intercellular matrix ground substances generally are also permeable.

Other features of the invention appear in the following specification.

Abstract: A freeze-dried soluble coffee product in the form of particles or granules and having a microporous structure is prepared by prechilling a metal plate in a liquid refrigerant, immersing the plate in aqueous extract of coffee solids, reimmersing the plate in a liquid refrigerant, removing the frozen particles in the form of flakes from the plate, grinding and freeze-drying the flakes to produce frozen extract particles with reduced entrainment losses. The product so prepared has a unique porosity and is capable of sorbing, retaining and releasing volatile aromatic compounds.

Abstract: Dry chip-like discs of provisions or fine foods and a process for producing such discs. Raw food materials containing builder materials and soluble ingredients are converted into an essentially homogeneous pulp, and are brought into a composition which, as regards taste, is ready to be consumed. This pulp, having a consistency from flowable to pasty, is shaped into discs having a thickness of from 1 to 10 mm and is carefully dried, thereby substantially maintaining the builder structure and the thickness of the layer of the disc. The discs so produced are suitable for immediate consumption without previous mixing with liquids, and are converted back into a pulp by saliva in the mouth, the presence of the discs in the mouth stimulating the production of saliva.

The treatment is with a solid ligneous adsorbent of vegetable origin in divided form at a temperature of from 0.degree. to 100.degree. C. so as to absorb the caffeine and the chlorogenic acid. The combination of extract and ligneous adsorbent is dried by freeze-drying. The dried combination is thereafter introduced into infusing bags. On infusing the bags in hot water, an extract is obtained in partially decaffeinated and partially deacidified form.

Abstract: The color of freeze dried coffee can be darkened by carefully controlling the pressure in the drying chamber during the first 1 to 5 hours of the drying cycle. By maintaining the pressure at between 350 to 650 microns of mercury for the specified time, a surface darkening is achieved without allowing the product to actually melt or puff. Thus, a high quality freeze dried coffee is obtained with a more desirable appearance.

Abstract: Method of compacting freeze-dried particulate foods comprising partially freeze-vacuum-dehydrating a food in particulate form to an average moisture content of about 10-35 percent, irradiating the frozen partially freeze-vacuum-dehydrated food with microwaves to rapidly distribute the remaining mositure from the frozen cores of the food particle throughout the food and thereby to uniformly plasticize the food, compressing the irradiated food to from about 5 to about 50 percent of its volume prior to compression, and thereafter redehydrating the compressed food to from about 1 to about 5 percent moisture content. The food particles may be either uncooked or cooked prior to partial freeze-vacuum-dehydration thereof, but will preferably be uncooked in the case of a vegetable and cooked in the case of a meat. The final redehydrated, compacted food mass may be hermetically sealed in moisture-impermeable containers to impart long-term storage stability thereto.

Abstract: A low-grade roasted coffee fraction is extracted with water in manner sufficient to remove at least 75% of the caffeine contained therein while retaining a major amount of the soluble solids. Volatiles are stripped from the resulting extract and condensed. Thereafter the low grade fraction is thoroughly extracted with an aqueous extraction medium and this extract is combined, either before or after drying, with a fully caffeinated water extract of a high-grade coffee fraction and with condensed volatiles from the stripping operation. A partially decaffeinated soluble coffee having desirable flavor and aroma may be obtained.
