Embodiment approach

[0055] In a representative day of production, one embodiment of the invention proceeds as follows:

[0056] 1) Use the process shown in Figure 2 and above to form a soybean germ concentrate.

[0057] 2) After blending, the moisture content of soybeans is 9.8%.

[0058] 3) The sieve sizes used are those described above.

[0059] 4) The suction pressure used to remove the hulls from the soybean germ concentrate is 0.8 inches of water pressure.

[0060] 5) The particle size distribution after the first crushing step (20) is as follows. Samples were withdrawn approximately every 30 minutes over four hours.

[0061] The following US sieves were used and the data reported are expressed as wt% retained on the sieve. Use the following method. (AACC 55-30 and AOCS Da 28(97))

[0062] #4 4.75mm; #5 4.00mm; #6 3.35mm; #7 2.80mm;

[0063] #8 2.38mm; #10 2.00mm; #12 1.70mm.

Embodiment 2

[0091] During a representative two-day production cycle, samples of soybean oil and soybean meal were taken under the following two conditions: (a) On the first day, the soybean germ separation equipment was turned off so that the soybean germ was not separated from the feed stream and (b) On the second day, the soybean germ separation equipment was opened and the soybean germ was separated from the feed stream as described above in Example 1. Four samples of all crude soybean oil and soybean meal were taken under each condition.

[0092] Samples were taken at approximately 20 minute intervals. Soybean oil samples were tested for total sterol content (% sterols) (see AOCS Ca 60-40, AOCS Ce 3-74 and AOCS Ch 6-91). Soy flour samples were tested for total isoflavone content (% isoflavones) (see Murphy, Patricia A. et al., Isoflavones in Retail and Industrial Soy Foods, J. Agric. Food Chem., vol. 47, pp. 2697-2704 ). The isoflavone content is expressed as a range because the re...

Abstract

Methods are provided for forming soy germ concentrate in a soybean processing operation that produces soy bean oil and soybean meal.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation-in-part of and claims priority from US Application Serial No. 60 / 247,845, filed November 9, 2000, the entire disclosure of which is incorporated herein by reference. technical field [0003] This invention relates to the processing of soybeans, and more particularly to the production of soybean germ concentrates. Background technique [0004] Soybeans have been utilized for thousands of years as a source of oil and protein. It is now one of the most important agricultural sources of important products for animal and human consumption. In addition, many industrial applications of soybean oil have been developed with the growing concern for the long-term supply of petroleum products. Soybean oil is usually separated from the solids by extraction with an organic solvent, although other methods exist. The soybean product remaining after oil extraction is either desolvated and toasted t...
