Snack Meals Extruder Machine
To produce a dispersible powder product, the extract from the cooling stage 18 is shipped to a concentration stage 20, followed by a twig drying stage 22, after which an instantizing stage 24. From about 3 to about 15 elements by weight of the new alkaline extraction solution per part oilseed are used. [newline]If less than about 3 elements are used it's discovered that the resulting slurry is just too viscous to deal with when soy beans are used because the feed. At Snack food extruder machine than about 15 the vitality requirements turn into prohibitively costly in concentrating and spray drying the extract. In addition excessive ranges of extraction resolution lower the yield of the method as a end result of oilseed extracts are typically discarded with the sludge produced within the clarifying stage.
The Chayen process does overcome a few of the disadvantages of the hydrocarbon extraction process. Any residual taste from the hydrocarbons is eradicated. A product produced by the process of claim 19. As used herein, the term "comminution" refers to any high pace process of dimension discount, together with, however not limited to chopping, crushing, tearing, shredding, emulsifying and grinding by appropriate equipment.
Although not sure by concept I imagine that the high stability of the product is due to the high share of sure lipids. It seems that the fats particles are encapsulated by a protein by-product throughout excessive pace comminution within the presence of the high temperature, excessive pH extraction answer. It seems that the alkali, quite than hydrolyzing the fats, reacts preferentially with the protein and, in impact, produces a protecting colloid for the fats.
The resultant product should be of good initial taste and be stable with minimal rancidity and minimal taste improvement in storage. The product must be primarily freed from fiber, and within the case of soy beans, as the supply vegetable materials, the resultant product mustn't have a beany flavor. The product additionally should be water dispersible and compatible with other meals supplies corresponding to whey, in order that it can be mixed with these meals supplies to yield nutritious and palatable food stuffs. After comminution, the oilseed is soaked in the extraction solution in the extraction stage 12 for from about 1 to about 20 minutes, and ideally about 3 to about 7 minutes.
The most popular equipment for comminution is a hammermill, which has been proven to satisfactorily produce a fantastic grind of oilseed within the presence of the extraction resolution. An added benefit of a hammermill is that it tends to aerate the extraction resolution. To overcome the disadvantages of hydrocarbon solvent extraction methods researchers have developed water extraction techniques. Chayen, in U.S. Pat.
The preferred chemical is sodium hydroxide as a outcome of it's inexpensive and available. To this end, a lot attention has been directed to soy beans and peanuts as potential protein sources. Ordinarily soy proteins are extracted from fat-free flakes.
DESCRIPTION OF THE INVENTION Referring to the FIGURE, an oilseed is comminuted in a comminution stage 10 within the presence of an extraction resolution. Furthermore, there could also be a residual off-flavor as a outcome of hydrocarbon solvent. In addition, the usage of hydrocarbon solvents leads to processing difficulties as a end result of flammable and explosive nature of the solvents and air air pollution problems related to hydrocarbons. A course of as claimed in declare 38 whereby the comminuted oilseed/extraction resolution mixture has a pH from about eight.5 to about 9. A course of as claimed in claim 38 wherein the comminuted oilseed/extraction solution mixture has a pH from about 8 to about 10. A process as claimed in declare 17 whereby the comminuted oilseed/extraction resolution mixture has a pH lower than about eleven.
