Snack Meals Extruder Machine
However, Chayen's course of has disadvantages. Only proteins and lipids, however not carbohydrates are recovered from the feed vegetable materials. Also, Chayen reports a yield of less than 50% of his protein-fat advanced on check with peanuts. Such low yields are of restricted industrial value.
No. 2,928,821 describes a way of manufacturing a protein-lipid advanced from vegetable materials. Chayen states that the popular temperature of the liquid fed into the hammermill is about 45°-55° F. The comminution can occur under atmospheric stress, or in the presence of a vacuum to withdraw the volatile components responsive for the beany flavor of soy bean products.
Alternatively, the sludge may be further extracted in a quantity of recycle phases the place every stage consists of the steps of soaking the sludge in water after which clarifying the sludge/water combination. Because the Wilkens and Hackler course of requires that the soy bean feed be both presoaked or dehulled, a facility utilizing this process would have further operating and capital prices. Improved yield could also be achieved by extracting with water residual meals values which may be in the sludge. Malnutrition as a result of protein deficiency is a significant issue in plenty of elements of the world.
Normally people indirectly acquire protein from vegetable materials by consuming animals which devour the vegetable materials. It can be extra environment friendly if it have been possible for people to directly consume extra protein in vegetable materials with out having to rely on animal intermediaries. Based on the total soluble solids within the clarified extract, the yield based on the beginning beans was 76.1%. The soya powder produced had a good flavor and good wetting characteristics.
The most popular machinery for comminution is a hammermill, which has been proven to satisfactorily produce a fantastic grind of oilseed within the presence of the extraction solution. snack machine added benefit of a hammermill is that it tends to aerate the extraction answer. To overcome the disadvantages of hydrocarbon solvent extraction strategies researchers have developed water extraction techniques. Chayen, in U.S. Pat.
Generally the higher the temperature used, the less residence time required in the heating stage. For instance, the extract can be maintained at about 285° F for about 15 seconds in the heating stage to destroy anti-nutritional components. This step may not be required for all types of oilseeds.
Preferably the extraction resolution contains sodium hydroxide, and the temperature of the extraction resolution is close to boiling, i.e., about 205° F. After comminution the oilseed is soaked in the extraction resolution for from about 1 to about 20, and preferably from about three to about 7 minutes to extract protein, carbohydrates and lipids from the seed material. After the extraction step, the comminuted oilseed/extraction answer mixture is neutralized with an acidic answer, which preferably contains hydrochloric acid. The neutralized mixture is then centrifuged to yield an basically clear extract and a sludge. After comminution, the oilseed is soaked within the extraction answer in an extraction stage and then the comminuted oilseed/extraction resolution mixture is neutralized with an acidic solution. After clarification in a clarification stage 14, the extract is heated in a heating stage 16 to destroy anti-nutritional components after which cooled in a cooling stage 18.
The Chayen course of does overcome some of the disadvantages of the hydrocarbon extraction process. Any residual style from the hydrocarbons is eliminated. A product produced by the method of claim 19. As used herein, the time period "comminution" refers to any high velocity process of dimension discount, together with, however not restricted to chopping, crushing, tearing, shredding, emulsifying and grinding by suitable equipment.
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 may be a residual off-flavor because of the hydrocarbon solvent. In addition, the use of hydrocarbon solvents results in processing difficulties because of the flammable and explosive nature of the solvents and air air pollution issues related to hydrocarbons. A course of as claimed in declare 38 wherein the comminuted oilseed/extraction answer combination has a pH from about 8.5 to about 9. A course of as claimed in claim 38 whereby the comminuted oilseed/extraction resolution mixture has a pH from about eight to about 10. A process as claimed in declare 17 whereby the comminuted oilseed/extraction answer combination has a pH lower than about 11.
BACKGROUND OF THE INVENTION This invention relates to meals products, and particularly to food products obtainable from oilseeds, as for instance, soy beans and peanuts. A course of as claimed in declare 38 whereby the hammermill is utilized for comminuting the oilseeds. A process as claimed in declare 17 whereby a hammermill is utilized for comminuting the oilseeds. A course of as claimed in claim 1 whereby a hammermill is utilized for comminuting the oilseeds.
