  • Patent number: 10633678
    Abstract: The present invention provides a process for the production of a microbial oil comprising culturing a micro-organism in a two stage fermentation process where, in a last stage that precedes the end of fermentation, the carbon source is: consumed by the micro-organisms at a rate greater than it is added to the medium; added at a rate #0.30 M carbon/kg medium; or is rate limiting on the growth of the micro-organism. The micro-organisms thus have the carbon source restricted so that they preferentially metabolise fats or lipids other than arachidonic acid (ARA), so increasing the proportion of ARA in the cells. A microbial oil is then recovered from the micro-organism, using hexane as a solvent, that has at least 50% ARA and at least 90% triglycerides.

  • Publication number: 20130017294
    Abstract: The invention relates to a method for the preparation of fried vegetable products. In particular, it relates to a method for the preparation of fried vegetable products which have been subjected to an asparagine-reducing enzyme. The method comprises reducing the amount of enzyme product formed on the surface of the enzyme-treated vegetable material due to the action of the asparagine-reducing enzyme. If the amount of enzyme product is reduced before frying, this will contribute to the colour and the quality of the frying oil and of products subsequently fried in the oil and, thus, will minimize the loss of quality of the frying oil. The invention also relates to use of an asparagine-reducing enzyme preparation for preserving the colour of the frying oil.

  • Publication number: 20110091599
    Abstract: The present invention relates to a method for preparing dough. Particularly the invention relates to a method for producing dough that can be processed via sheeting (i.e. a sheetable dough). Even more particular, the invention relates to a method for manufacturing sheetable dough with a water addition level which level would normally result in a dough which can not be processed because it is too sticky. The present invention provides a method for preparing sheetable dough comprising adding an amount of water and an effective amount of oxidase to flour and wherein said amount of water in the absence of said oxidase results in a dough that can not be processed due to its stickiness.

  • Publication number: 20090105342
    Abstract: Edible formulations, such as polyunsaturated fatty acids (PUFAs) such as pharmaceutical compositions or nutritional supplements, are disclosed comprising arachidonic acid (ARA). They are adapted to deliver from 150 mg to 1 g per day of ARA and may contain other PUFAs, for example docosahexaenoic acid (DHA). The DHA dosage is from 400 to 600 mg per day, and the ratio of ARA:DHA may be from 1:5 to 5:1. Pharmaceutical compositions comprising ARA and DHA at a ratio of ARA:DHA of 1:1 to 1:2 are also disclosed, as are foodstuffs comprising 0.1 to 5% ARA. Such formulations can be used to increase ARA levels in vivo, for example in pregnant women or for people who have diseases or conditions associated with low ARA levels.
