Process for reducing the patulinconcentration in fruit juices.

Patent Number: WO 98/43500
Author: Miller C.J., Lyndon R.M.
Language: English

Abstract: Patulin is amycotoxin produced by Penicillium expansum and other fungi that may be found on rottingfruit. It has been detected in apple juices, and levels are usually higher in cloudyjuices than in clear juices. A method is described for treating fruit juice to reduce thepatulin concentration. The juice is passed through a resin material with micropores thatare capable of retaining patulin on the pore surface by chemisorption (van der Waals andLondon dispersion interactions). Regeneration is achieved by conversion of the adsorbedpatulin to an easily removed derivative, using ammonia or a volatile base preferablygenerated in situ. The process of patulin reduction is performed after pasteurization,partial flocculation, and ultrafiltration.

It is traditionally grown on a substrate of black tea withsucrose under aerobic conditions. The fermented tea can have an alcohol content of up to1.5%. A non-fermenting food product containing Kombucha is described. The fermentation isterminated by filtration (for production of beverages) or by increasing the sugar contentabove 60% (for syrups and confectionery products). The products contain less acetic acidthan traditional Kombucha, and have lower total acidity and improved taste and odourproperties.

Liquid plastic film pouch withinner straw and machine and method of making.

Patent Number: WO 98/38110
Author: Larson R.L., Savoury R., Edwards J.
Language: English

Abstract: A flexible plasticpouch is described for a liquid, particularly a beverage that is consumed through a rigiddrinking straw. The straw floats freely in the liquid product. The liquid occupies 60-90%of the volume of the interior of the pouch. The remaining air is partially evacuated toallow the side walls to be collapsed against each other when the pouch is held by theuser. The straw is grasped and manipulated to puncture the pouch. The pouch is made from amultilayer resin film with an inner sealant layer formed from a linear low-densityethylene/octene copolymer or very-low-density ethylene copolymer. When the straw puncturesthe film, the inner sealant layer forms a membrane around the straw. This exhibitsself-sealing behaviour, preventing leakage of contents through the puncture hole.
