Embodiment 1

[0122] Embodiment 1: the preparation of soybean germ enrichment

[0123] This example illustrates one method of the invention.

[0124] Whole soybeans are carefully selected and impurities such as stems, stones, etc. are removed. The cleaned soybeans are then heated for 5 minutes to about 75°C and then crushed using an impact mill to about 1 / 2 the size of their original state (cotyledons or watercress formed) to obtain a mixture of skins, germs, lobes and cotyledons . The skin fraction was removed from the mixture using moderate suction (method a) to obtain a dehulled fraction producing mainly cotyledons, lobes and germ.

[0125] The dehulled fraction was further enriched in smaller lobes and germs by sieving the leaflets (and larger lobes) and aspirating the remaining skins. Size / weight / gravity differences were used to separate the dehulled fraction, from which a mixture of embryos and smaller lobes of approximately equal density was obtained.

Embodiment 2

[0128] Embodiment 2: Preparation & composition of soybean hypocotyl oil & meal

[0129] This example illustrates the preparation & composition of soybean germ oil. The soybean germ oil is hexane or supercritical CO 2 Obtained by extracting the soybean hypocotyl enrichment in Example 1.

[0130] Soybean germ oil extracted from hexane contained 5.2% total phytosterols (by weight) and 21.3% linolenic acid (C18:3), based on total fatty acid weight. The oil also contains other fatty acids based on total fatty acid weight such as C16:0 (13.8%); C18:0 (3.5%); C18:1 (7.2%); C18:2 (53.5%); 0.7%). The oil also contained 2230 ppm (by weight) of total tocopherols.

[0131] Before extraction, the germ is ground to a diameter of less than 750 μm. with supercritical CO 2 (250 bar; 40°C) extracted (6h) soybean germ oil contained 7.2% total sterols (by weight) and 22.1% linolenic acid (C18:3) based on total fatty acid weight. The oil also contains other fatty acids based on total fatt...

Abstract

The present invention relates to a method for processing soybean (or soya) material, which is mainly a mixture of soybean hypocotyls and soybean cracks. In particular, the present invention provides a method for separating a soybean hypocotyl fraction from a soybean crack fraction based on a difference in form, by subjecting said soybean material to a centrifugal force, preferably by use of an indented cylindrical device. On beforehand, it is preferable to remove the main part of the soybean hulls, soybean cotyledons, whole soybeans, and the larger soybean crack fraction from the soybean material by means of traditional separation methods based on differences in size and/or weight (e.g. aspiration). The invention also provides a soybean hypocotyl concentrate and uses thereof, e.g. for the preparation of a soybean hypocotyl (or germ or embryo) oil and/or food products.

Description

technical field [0001] The invention relates to the field of food technology, in particular to a method for obtaining highly purified and complete soybean hypocotyls. Specifically, the present invention provides a method for separating soybean material mainly comprising soybean germ and soybean splits into a soybean germ enrichment mainly containing whole germ. The present invention also provides a soybean germ enrichment and its use, for example for preparing soybean germ oil and / or food. Background technique [0002] Soybeans have been used as a source of oil and protein for thousands of years. Most of this crop is solvent extracted to obtain vegetable oil, while defatted soybean meal is used as animal feed. A small portion of this crop is consumed directly by humans. Soy products do appear in a variety of processed foods. [0003] Raw soybeans basically consist of three main parts: the outer covering, called the hull; the two bean segments, also called the flesh or co...
