摘要:
A granular composition containing dietary fibers derived from green tea and a method for preparing the same are provided. The granular composition may be prepared into granules, which has a suitable size and a shape to eat, using dietary fiber-containing processed green tea, an oligosaccharide and a sugar alcohol as raw materials. The granular composition may also be useful in solving the problems such as dust scattering, choking, and the like due to the good flowability of the granules, and manufacturing goods because the granular composition is easy to quantify due to the good filling properties.
摘要:
A tea-flavoured beverage concentrate, comprising a beverage concentrate base in which tea flavour is provided by the incorporation of tea distillate. Dilution of this composition results in a tea-flavoured beverage that suffers from less of the cloudiness, precipitation or sedimentation that has previously been encountered in preparing tea-flavoured concentrates.
摘要:
Stabilized aroma-providing components such as chocolate, tea or coffee aromas that are stabilized against loss or degradation of desirable flavor or sensory characteristics of its aroma during storage. The stabilizing agent is present with the aroma-providing component in an amount effective to chemically interact with compounds in the aroma-providing component to (a) provide increased amounts of desirable compounds that impart desirable flavor or sensory characteristics to the aroma or (b) reduce the amount of undesirable compounds that suppress desirable flavor characteristics or that contribute to or generate undesirable flavor or sensory characteristics in the aroma. The stabilizing agent preferably is a nucleophile that contains sulfur or nitrogen, such as sulfur dioxide, sulfites, compounds or substances that contain or generate sulfites, thiols, amines or amino acids, cysteine, gluathione or an enzyme. The stabilized aroma-providing component retains the desirable flavor and sensory characteristics of the aroma for a time period of at least six months to one year or longer.
摘要:
The present invention relates to hot water soluble instant tea and provides a method for preparing an extract, concentrate or powder, which is capable of being reconstituted as a tea beverage, having excellent organoleptic properties and substantially free of undesirable cloudiness and haze, and resembling conventional tea in taste and character.
摘要:
Natural cocoa flavor and aroma compositions are prepared by passing a natural aroma gas, preferably from cocoa beans, through one or more condensers to remove water and substantially all the acetic acid present therein. The aroma gas may then be placed into a cryogenic collector in which liquid nitrogen is sprayed directly into the aroma gas stream to rapidly condense the aroma frost suspended in a stream of nitrogen gas, while minimizing contract of the cooled gas with the walls of the collector. The suspension of aroma frost particles in gaseous nitrogen is passed through a tubular porous filter to remove the aroma frost particles which collect on the outer surface of the tubular filter, with the nitrogen gas passing through the porous filter and being exhausted from the collector. The aroma particles recovered are suitable for incorporation in various food products where a natural cocoa or chocolate flavor is desired, including soluble cocoa products, cake mixes, confectionery products, and the like.
摘要:
A process for providing aroma in a container for a product such as instant coffee. Empty, open-topped containers are conveyed one after the other to beneath an aroma spraying station which contains at least one spraying nozzle. Once an open-topped container is positioned substantially beneath a spraying nozzle, the spraying nozzle is activated and aroma is dispensed into the open top of the container while the open-topped container continues to be conveyed. The aroma is dispensed in the form of fine droplets to coat the inner side walls of the open-topped container. The spraying is then discontinued while the open-topped container is still beneath the spraying nozzle. The container may then be transferred to a filling station where product may be filled into the container. In this way, aroma may be incorporated into a product at production rates of 200 to 500 containers per minute.
摘要:
An antifoam for incorporation with a vegetable extract is prepared by reacting a vegetable oil with calcium and magnesium cations which may be derived from ash of a vegetable material in an aqueous alkaline environment. The antifoam may be itself incorporated with a vegetable extract or may be mixed with a carrier oil and incorporated with liquid or dry vegetable extracts to form a vegetable extract composition of the present invention. Particularly useful in practicing the invention are extract, oil and ash derived from tea and coffee. Further advantages, particularly in the case of tea, derive from aromatics which may be incorporated in the carrier oil by contacting the carrier oil with an aqueous tea essence.
摘要:
By the extraction with CO.sub.2 at 60 to 150 bar and 20.degree. to 70.degree. C., an aroma enriched fraction is taken from the moistened black tea, said fraction being added again to already decaffeinated and dried tea. Decaffeination starts after the aroma fraction has been obtained by pumping carbon dioxide at a pressure of between 150 to 500 bar and a temperature of between 10.degree. to 100.degree. C. through a bulk moistened tea. The solvent charged with caffeine is passed over an adsorber or purified by reduction of density.
摘要:
A process for isolating and purifying green tea solids in good yield is described. The process uses food approved solvents and provides flavanols with less green/grassy flavor. A less bitter and less astringent flavanol pectin complex is also prepared using pectins, cellulose, gums or sugars.
摘要:
Aroma- and flavor-bearing substrates are separated into an aroma concentrate and a flavor concentrate by pulsing or applying in a continuous fashion wet steam to a zone containing the substrate. The substrate-containing zone is held under vacuum pressure and the flavor concentrate is collected in a first trap, while an aroma concentrate is collected in a second trap. In one preferred embodiment, the most volatile flavor and aroma bodies are collected and subsequently dissolved in a solution of solids (e.g., those obtained from further extraction of the substrate) and the solution is then frozen and freeze-dried to yield a highly stable dry aroma and flavor bearing product. In a preferred embodiment, the substrate comprises either coffee or tea.
