Abstract: The invention concerns a method of reducing the organoleptic effect of undesirable aldehydic components in a triglyceride or derivative thereof by addition of a reaction product of an amine and an organoleptically acceptable aldehyde. The triglyceride may be a food or food component such as an edible fat or a surface active agent such as a detergent. The reaction product may be incorporated in the perfume or flavour to be added to the triglyceride or derivative thereof without distorting their organoleptic effect.

Abstract: A method of processing a solid plant foodstuff comprises (a) heating the plant foodstuff using a mass heating method, according to which, during at least part of the heating step, the environmental pressure of the foodstuff being heated is so controlled in relation to the saturated vapour pressure of the foodstuff as to achieve a substantially uniform temperature through-out the solid foodstuff at the maximum temperature to be attained; (b) cooling the foodstuff by evaporation achieved by maintaining the environmental pressure of the foodstuff lower than the saturated vapour pressure of the foodstuff; characterised in that the time the plant foodstuff is at a temperature above 118.degree. C. is less than 29 seconds, and the time for which the plant foodstuff is above 70.degree. C. is less than approximately 100 seconds.

Abstract: A soft-milling wheat which produces dough having exceptionally low visco-elasticity is provided by breeding from a variety having Glu-Dl double null trait, such as the landrace "Nap Hal". The wheat can be used in the manufacture of biscuits and wafers without the need to treat the flour with agents such as sodium metabisulphite.
Abstract: The present invention provides a microwaveable food product composite containing a coating food product and a mode filtering structure wherein the food product has a crumb coating having an average crumb size of greater than 1.5 mm and an air gap of from 1 to 6 mm between the food product and the mode filtering structure such that the electric field strength generated within the mode filtering structure, when used in a commercially available microwave oven, is greater than 20 kV/m, but below the breakdown voltage of air. Such composite products are useful in enhancing the heating of the surface layer of the coated food product by a microwave energy.

Abstract: The structural genes and their regulatory DNA sequences of an alcohol oxidase (MOX) and a dihydroxyacetone synthase (DHAS) of Hansenula polymorpha have been isolated and the nucleotide sequences determined. The invention relates to the use of the MOX gene, as well as the use of the regulatory DNA sequences of MOX and/or DAS in combination with the MOX gene, optionally after modification thereof, or other oxidase genes, or other genes, to produce engineered microorganisms, 0in particular yeasts. Said engineered microorganisms can produce oxidases or other enzymes in yields that allow industrial application on a large scale. Moreover, said engineered microorganisms can produce oxidases having improved properties with respect to their application in oxidation reactions and/or in bleaching and detergent products.

Abstract: A method of processing a solid foodstuff, such as a meat portion or portion of plant foodstuff, by a heating and cooling cycle in which the environmental pressure applied to the foodstuff is controlled during heating so that, at a maximum target temperature, all parts of the body of the foodstuff are conformed to this target temperature due to flow of water, transiently in the vapour phase, from hotter regions to cooler regions. In particular, at least when the target temperature is nominally attained, the pressure is set to the saturated vapour pressure of the foodstuff at the maximum target temperature.
