Compositions containing toasted soybean flakes and potato flakes
The invention relates to an improved compositions comprising mixtures of toasted soybean flakes and potato flakes, for making highly soy protein enriched and soy oil containing mashed potato products having excellent nutritional, taste and texture properties. The toasted soybean flakes are made from full fat, enzyme active, dehulled soybean flakes. Additionally, the invention relates to methods for making said highly soy protein enriched and soy oil containing mashed potato products from said compositions; and to said highly soy protein enriched and soy oil containing mashed potato products per se.
1. A composition for making soy protein enriched and soy oil containing mashed potato product comprising:
(i) from 20 to 60% by weight toasted full fat, enzyme active soybean flakes made from full fat, enzyme active, dehulled soybeans, wherein the flakes have been toasted for a sufficient time and at a sufficient temperature to substantially reduce beany and off-flavors; and,
(ii) from 80 to 40% by weight potato flakes.
2. The composition of claim 1 wherein the toasted full fat, enzyme active soybean flakes are prepared from soybean flakes made from full fat, enzyme active, dehulled soybeans, with substantially none of the fat/oil being removed during preparation of and subsequent toasting of the flakes, and in the composition contains about 40% toasted soybean flakes.
3. The composition of claim 2 wherein the soybean flakes have a thickness of about 0.2 mm.
4. The composition of claim 1 comprising:
i) from 45 to 60% by weight toasted soybean flakes; and,
ii) from 65 to 40% by weight potato flakes.
5. The composition of claim 4 wherein the soybean flakes have a thickness of about 0.2 mm.
6. The composition of claim 1 , wherein the toasted full fat, enzyme active soybean flakes are prepared using soybean flakes made from full fat, enzyme active, dehulled hilum soybeans.
7. The composition of claim 1 , wherein the toasted soybean flakes are made from soybean flakes prepared according to the method comprising:
(i) brushing the soybeans;
(ii) adjusting the water content of the soybeans to facilitate separation of the skin portion of the soybean from the flesh portion thereof;
(iii) separating the skin portions of the soybeans from the flesh portions;
(iv) simultaneous with separating dividing each flesh portion into four to eight flesh parts;
(v) passing the flesh parts through flat-pressing rollers, whereby a product in the form of a mass of uniformly distributed flakes results; and,
(vi) toasting the flakes for a sufficient time and at a sufficient temperature to substantially reduce beany and off-flavors.
8. The composition of claim 1 , wherein the toasted soybean flakes are prepared from soybean flakes with have been quickly heated in a hot fluidizing gas for a time and at a temperature sufficient to substantially reduce beany and off-flavors, but insufficient to cause any substantial denaturing of the soy proteins.
9. The composition of claim 1 wherein the composition contains about 60% toasted soybean flakes prepared from soybean flakes made from full fat, enzyme active, dehulled soybeans.
10. The composition of claim 1 wherein the toasted soybean flakes are made from soybean flakes prepared from mechanically dehulled and processed soybeans.
11. The composition of claim 1 wherein the soybean flakes have a thickness of about 0.2 mm.
