  • Patent number: 5229157
    Abstract: A method of preparing an aerated vegetable product comprising starch, oil and a heat-setting material. The method involves mixing the individual components and thereafter aerating with a gaseous material. The method is for example well suited to the preparation of an aerated potato product which has a different taste and texture compared to mashed potato. Other vegetable products can be made from for example sweetcorn, carrot or pea. Furthermore, products made according to the invention can retain their structure after being frozen and subsequently reheated.

  • Patent number: 5198259
    Abstract: The present invention relates to a process for the preparation of a concentrated tea extract comprising the steps of:(a) extracting tea-leaves with water having a temperature between 15.degree. and 50.degree. C. and separating the first extract from the tea-leaves;(b) extracting tea-leaves which have previously been extracted with water between 15.degree. and 50.degree. C. for a second time, with water having a temperature of more than 50.degree. C. and separating the second extract from the tea-leaves;(c) concentrating said first extract to obtain a first concentrate;(d) concentrating said second extract to obtain a second concentrate; and(e) combining said first and second concentrate,wherein said first extract is concentrated by subjecting it to reverse osmosis at a temperature between 20.degree. and 50.degree. C. and said second extract is concentrated between 50.degree. and 100.degree. C.

  • Patent number: 5135762
    Abstract: Twin compartment packets, e.g. tea bags, are formed with the compartments connected at the heads of the packet and optionally at the tails. The packets are produced from a pair of compartmented tubular webs that are brought together with the compartments in register, the webs then being interconnected at the compartment end seals and severed at those seals to form the separate packets. Apparatus for performing the process deposits doses of tea at spaced intervals onto the two separate webs before forming them into the tubular compartmented webs, brings the compartments of the two webs into register, interconnects the registered compartments, and separates the interconnected compartments into individual packets while the web advances continuously through the apparatus. The process is capable of high production rates because the webs are able to move through the successive stages at a uniform speed.

  • Patent number: 5082674
    Abstract: A process for the manufacture of a lysophospholipoprotein (LPLP)-comprising foodstuff by incorporating dried LPLP or dried LPLP-comprising material, preferably having a moisture content of at most 10 wt %, at a level of 0.1-90 wt.% therein. The dried LPLP serves as a texture-modifying agent, a glossing agent, a freeze-thaw stabilizing agent, a heat-stabilizing agent and a syneresis-inhibiting agent.

  • Patent number: 5027577
    Abstract: For use with automatic machinery for packaging a food product in foil pouches and then inserting a desired number of pouches in a box, a method and apparatus for scanning the boxes to check for missing pouches. The scan is accomplished by applying like alternating magnetic fields through each box and through the foil used to make the pouches at a point upstream from where the pouches are formed. Detected field absorption associated with the upstream foil is used as a reference, and the difference between it and detected field absorption associated with a box is proportional to the number of pouches in the box. The apparatus can detect if one out of two, one out of three, or one out of four is missing, and compensates the differential signal for variations in foil thickness by multiplying the reference signal by N-1, where N is desired pouch count per box. If a pouch is missing from a box, a signal is generated which can be used to trigger a rejection mechanism to remove the short-count box.

  • Patent number: 4976978
    Abstract: A method for preparing a food product is disclosed wherein formed food is prepared with a particulate coating. Here a plastic, deformable food material is made from rolling a food in the presence of particulate coating material in a revolving drum to thereby reshape the food particle into a roundish, coated body. The roundish body is preferably spherical, annular or roundish cylindrical. The food material is, for instance, mashed potato, minced fish or dough and preferably an aerated, frozen confection.
