Snack Food Extruder Machine
From about three to about 15 parts by weight of the hot alkaline extraction resolution per half oilseed are used. [newline]If lower than about 3 elements are used it is discovered that the ensuing slurry is simply too viscous to deal with when soy beans are used as the feed. At ratios higher than about 15 the power necessities turn out to be prohibitively costly in concentrating and spray drying the extract. In addition high ranges of extraction resolution decrease the yield of the method because oilseed extracts tend to be discarded with the sludge produced within the clarifying stage. The resultant product should be of fine initial flavor and be stable with minimal rancidity and minimal taste growth in storage.
After comminution, the oilseed is soaked within the extraction resolution in an extraction stage and then the comminuted oilseed/extraction resolution mixture is neutralized with an acidic answer. After clarification in a clarification stage 14, the extract is heated in a heating stage sixteen to destroy anti-nutritional components and then cooled in a cooling stage 18. To produce a dispersible powder product, the extract from the cooling stage 18 is sent to a focus stage 20, adopted by a spray drying stage 22, after which an instantizing stage 24.
A centrifuge is useful for accomplishing the clarification step. Sludge, which consists primarily of the fibrous part of the oilseed is the byproduct of the clarification step. However, there are residual extractible lipids, proteins and carbohydrates in the sludge. Therefore the yield of the general course of may be improved by recycling a portion of the sludge to the comminution stage 10 or, as shown in the drawing, to the extraction stage 12 for additional extraction. A full fat, secure meals material derived from oilseeds is ready by comminuting oilseeds in the presence of a scorching alkaline extraction solution, after which allowing the comminuted seeds to soak in the solution. After neutralizing the answer, the extract is clarified and heated to destroy anti-nutritional elements, concentrated, and spray dried.
Snack food extruder machine , barely acidic, aqueous resolution extraction process for preparing soy milk from dehulled or presoaked beans is described by Wilkens and Hackler in "Cereal Chemistry," July 1969, Volume forty six, No. four, P. 391. BACKGROUND OF THE INVENTION This invention pertains to food merchandise, and especially to food products obtainable from oilseeds, as for instance, soy beans and peanuts. A process as claimed in claim 38 wherein the hammermill is utilized for comminuting the oilseeds. A process as claimed in declare 17 wherein a hammermill is utilized for comminuting the oilseeds. A process as claimed in claim 1 wherein a hammermill is utilized for comminuting the oilseeds.
Although not bound by theory I imagine that the excessive stability of the product is as a result of high percentage of certain lipids. It seems that the fat particles are encapsulated by a protein by-product during high pace comminution in the presence of the excessive temperature, high pH extraction solution. It appears that the alkali, somewhat than hydrolyzing the fat, reacts preferentially with the protein and, in effect, produces a protecting colloid for the fat. This could be described as an enrobing or an encapsulating effect.
This process can be utilized with dehulled soy beans or deskinned peanuts, with or with out presoaking. This process also can be used with entire soy beans and whole peanuts which have not been dehulled or presoaked, thereby eliminating the price of presoaking or dehulling related to other processes. Also, this course of is helpful for blends of oilseeds. For instance, a mix containing soy beans and peanuts could be handled with this course of. A water dispersible meals product derived from whole soy beans comprising lipids and proteins wherein no less than about 75% of the lipids are within the certain form and prepared by the process of claim 19. EXAMPLE 1 Commercial grade entire soy beans were fed to a Fitz mill at 3.3 kilos per minute.
