  • Patent number: 6025010
    Abstract: The invention relates to a low fat spread with low water content for application in baking without effecting organoleptic properties for cold use, (that is, spreads). The compositions of the invention are good quality spreads at low fat levels in the range of about 30-60% fat. The compositions of the invention comprise non gelling hydrocolloids to provide optimum viscosity to the aqueous phase at a concentration which results in a fat continuous emulsion.

  • Patent number: 6025171
    Abstract: Enzymes are immobilized by preparing an emulsion containing a continuous hydrophobic phase such as a triglyceride oil and a dispersed aqueous phase containing an amphiphilic enzyme such as lipase or phospholipase and carrier material that is partly dissolved and partly undissolved in the aqueous phase, and removing water from the aqueous phase until the phase turns into solid enzyme coated carrier particles. The undissolved part of the carrier material may be a material that is insoluble in water and oil, or a water soluble material in undissolved form because the aqueous phase is already saturated with the water soluble material. The aqueous phase may be formed with a crude lipase fermentation liquid containing fermentation residues and biomass that can serve as carrier materials. Immobilized lipase is useful for ester re-arrangement and de-acidification in oils.

  • Patent number: 5987857
    Abstract: Packing apparatus on a conveyor line for use in filling cartons with compressible articles comprises first and second tamping pistons (4,6) operating in sequence in a chamber (2) to successively compress the articles and drive them through a chute (2a) into a carton (C). A planar shutter (32) is provided at the bottom of the chute (2a) to close it between carton-filling operations. The chute and carton are separated by only the shutter so as to minimize the gap between them and also to facilitate the extension of the driving piston (6) into the container to pack the articles more firmly therein. The shutter rotates on a vertical axis offset from the chute with its lower face contacting the cartons and moves generally in the direction of advance of the carton along the conveyor line.

  • Patent number: 5952023
    Abstract: An improved process for the preparation of acid stable instant tea. Enzymatic extraction of black tea leaf using an enzyme cocktail adjusted to a critical pH is employed. Black tea is extracted with water containing tannase and one or more cell wall digesting enzymes, such as cellulase, pectinase, hemicellulase or VISCOZYME at a selected pH. The resulting tea extract can then be pasteurized, polished and made into a finished beverage or concentrated and dried in the usual manner. As a result, natural tea products are obtained which have improved acid stability, good color and good clarity.

  • Patent number: 5927179
    Abstract: A brewing apparatus is provided including a housing with a water inlet channel, a heater to heat water delivered through the channel and a water dispenser within the housing for providing a spray of hot water to a brewing pot. The brewing pot is releasably attachable to the housing and includes a filter receptacle positioned to receive the spray of water and outlet aperture for allowing brewed tea to exit. A filter basket for containing the tea leaves is lodged within the filter receptacle. The basket has a base with a wire mesh screen and an integrally formed non-porous siphon shroud projecting upwardly from a central area of the floor base, the shroud being closed at the top while open at the bottom. A siphoning tube is lodged within the aperture of the filter receptacle and open at both ends. When nested, the siphon shroud surrounds the siphoning tube to create a siphon arrangement for continuously removing tea extract fluid from the filter basket.

  • Patent number: 5882472
    Abstract: A tagged packet carries a tag which is attached to the main body of the packet by a thread. The thread comprises polypropylene so as to be attachable by heat sealing to the body. The body is made up of layers of sheet material also comprising thermoplastic material to allow the body to be closed by heat seals. The thread is secured to the face of the body at one edge at the same time as that edge is heat sealed and the heating for the thread seal is applied from the opposite face of the body whereas the adjacent regions of edge seal spaced from the thread has the heating applied through the first face. This arrangement gives closer control of the different conditions required for securing the thread and for sealing together only the sheet material of the body.

  • Patent number: 5878550
    Abstract: Infusion packets have envelopes of heat-sealable material with a looped thread within the packets to wring moisture from the packet in use. A central part of the thread loop is held in a widened region of one edge seal while the ends of the loop project through the opposite edge seal in which they are movable when the loop is to be contracted. The packets are produced by forming a continuous series of thread loops on one elongate web and placing doses of infusion material on a second elongate web before bringing the webs together with the thread loops and infusion material between them. The two webs are then welded together and the individual packets are separated from the joined webs.

  • Patent number: 5873216
    Abstract: A method and apparatus are provided for assembling together tags (6), thread (8) and a web of envelope material for producing tagged packets. The tags are held on spaced seats on the periphery of a rotary carrier (2) and the thread is laid over the carrier and the tags. It is formed into a convoluted shape on the peripheral surface of the carrier between the tags by laterally displaceable holding pins (12) or by being dispensed onto the carrier by a displaceable guide (50). The web is brought against the tags and thread and attached to them maintaining the convoluted pattern of the thread. The assembly of web, thread and tags is suitable for a subsequent form-filling operation to complete the packets.

  • Patent number: 5863575
    Abstract: Packets containing a flowable material are provided with a draw-string or thread to squeeze the packet contents. The packet envelope is formed from a doubled-over web which gives the packet a folded-over edge and which encloses an intermediate portion of the thread close to the folded-over edge. The end portions of the web extend from the intermediate portion of the thread to extend through the opposite edge of the packet. The external ends of the thread are secured to a tag which is attached to the outer face of the envelope. The thread intermediate portion is retained close to the folded-over edge by heat sealing. Apparatus is also described for producing the packets in a continuous or semi-continuous manner.

  • Patent number: 5863581
    Abstract: Tea products, particularly black leaf tea and tea powder, derived from green tea leaf are manufactured by a process involving addition of zeolite, preferably a synthetic sodium or potassium zeolite, for reaction with tea ingredients present or subsequently produced to generate red colour species. The tea products produce beverages having enhanced colour characteristics, in terms of colour properties and speed of colour generation, compared with conventional products.
