Patent number: 6355173Abstract: Oils, extracted from vegetables and animal tissues contain impurities such as waxes that can be removed in a refining process, including dewaxing of the oils that include removal of oils by filtration through membranes. During filtration, the impurities stick to the membranes, which causes a reduction in flux through the membranes. The initial top flux can be approached again by regularly cleaning the membranes including steps of: backblowing with gas, backflushing with edible oil, and treating the membranes with alkaline material. The cleaning method is particularly suitable for cleaning membranes in the form of microfilters having an average pore diameter of 0.5-5 &mgr;m, which are used in the refining process.Type: GrantFiled: April 28, 2000Date of Patent: March 12, 2002Assignee: Unilever Patent Holdings BVInventors: Henricus A. C. I. den Bieman, Jacobus Cornelis Segers, Vangelis Stavridis

Patent number: 6340101Abstract: In a process for dispensing a powdery product (P) from a container (1) with a dispensing nozzle (4) aimed downwards, a flexible section (3) of the container (1) is deformed at least near the dispensing nozzle (3). This is achieved preferably by a movement of the container relative to the dispensing nozzle, in a direction with a component at a right angle to the dispensing nozzle. The movement of the container (1) and the dispensing of a portion of product from the dispensing nozzle (4) can take place immediately after one another. The invention also comprises a device for dispensing a powdery product (P), with which the process can be carried out and bridge and tunnel formation in the powdery product is opposed effectively.Type: GrantFiled: March 9, 2000Date of Patent: January 22, 2002Assignee: Unilever Patent Holdings BVInventors: Maurice Adrianus Wilhelmus van Beek, Cornelis M Beijersbergen van Henegouwen, Lucas Alphonsus Maria Evers, Reni Louis Jean Lahaye, Marc van Megen, Peter Joost Wieriks

Patent number: 6338865Abstract: Olive oil is fortified with oleanolic acid by including olive leaves in the malaxation mash of conventional olive oil pressing in an amount of 5-50 wt. %, based on the weight of the malaxation mash. The invention comprises vegetable oils fortified with a concentrate of oleanolic acid and, optionally, oleuropein. Food products fortified with oleanolic acid containing oils or concentrates according to the invention are also part of the invention.Type: GrantFiled: December 22, 1999Date of Patent: January 15, 2002Assignee: Unilever Patent Holdings BVInventor: Karel Petrus Agnes Maria van Putte

Patent number: 6255115Abstract: The invention relates to Agrobacterium mediated transformation of moulds comprising species of the fungal sub-divisions Ascomycotina, Basidiomycotina, Deuteromycotina, Mastigomycotina, and Zygomycotina. Examples demonstrate the transformation of Aspergillus awamori (both protoplasts and conidia), Aspergillus nidulans, Aspergillus niger, Colletotrichum gloeosporioides, Fusarium solani pisi, Neurospora crassa, Trichoderma reesei, Pleurotus ostreatus and Agaricus bisporus (all conidia), and Fusarium graminearum (both conidia and rehydrated freeze dried ATCC material). Especially for Aspergillus awamori the transformation frequency is much higher than with conventional mould transformation techniques. It has further been found that not only one expressable gene can be introduced into these moulds, but even multiple copies of such gene, which, moreover, can be targeted e.g. in the chromosomal pyrG locus, as exemplified for A. awamori.Type: GrantFiled: October 7, 1999Date of Patent: July 3, 2001Assignee: Unilever Patent Holdings BVInventors: Alida Godelieve Maria Beijersbergen, Paul Bundock, Robertus Johannes Gouka, Marcellus Johannes Augustinus de Groot, Paul Jan Jacob Hooykaas
