  • Patent number: 4652455
    Abstract: A product of fish meat paste simulating the meat of the lobster containing a heat-coagulated mixture of one part by weight of fish meat paste and 0.2 to 2 parts by weight of mannan gel modified by freezing. The fish meat paste is made of "surimi" and at least one additive selected from salt, seasoning agents, starch and texturing agents. The modified mannan gel is in the form of flakes less than 3 mm thick to impart to the coagulated mixture a texture which gives a particular oral sensation as if real lobster meat were being eaten.

The admixture is placed on a filter and hot water is added. A portion of the finely divided mineral is dissolved in the hot water and passes through the filter along with the water soluble beverage ingredients. A small amount of the mineral solids also pass through the filter into the brewed beverage. A major portion of the mineral solids are retained on the filter surface, thereby retarding the brewing process and enhancing the extraction of flavoring ingredients from the particulate beverage base. The minerals added during the brewing process approximate those formed in fresh spring water and enhance the flavor of the brewed beverage.

  • Patent number: 4500556
    Abstract: Grape pomace is contacted with an aqueous extraction solvent containing HSO.sub.3.sup.- ions to form anthocyanin-(HSO.sub.3) complex. The complex is recovered by treating the liquid extract phase with a non-ionic adsorbent to adsorb the complex. Anthocyanin colorant, free of the HSO.sub.3.sup.- ions is recovered by elution with an acidified organic solvent for anthocyanin. The anthocyanin colorant may be provided in dry form by drying the solvent solution. This process allows us to remove sugars, organic acids, polymerized anthocyanin pigment and other water soluble material, thus providing a highly "colored" monomeric anthocyanin pigment. The anthocyanin colorant produced by this process is at least 10 times more concentrated than that produced by conventional methods and about two times stronger than most of the concentrated pigment.

    Abstract: This invention relates to the problem of water-soluble tablets, wherein dry, edible ingredients having a substantially granular or crystalline structure are blended to form a dry mix which is contacted with an aqueous moistener comprising corn syrup and admixed to form a dough or cohesive powder. The moistened dough or cohesive powder is then mixed with a hydrolyzed starch material to form a flowable composition which can be suitably compressed to form a coherent tablet, using tableting pressures below 200 psig that has a tablet density of about 0.7 to 1.0 grams per cubic centimeter. Optionally, said tablet may be subsequently dried to a stable moisture content to improve storage shelf-life. The resulting tablet is tough, void-free, non-crumbly and rapidly soluble in water.
