Snack Food Extruder Machine
Extraction solution on the rate of 4.0 gallons per minute was fed to the Fitz mill. The extraction solution was prepared by chlorinating 300 gallons of water to 0.01% and adding 1.1 liters of 50% sodium hydroxide to the water. The extraction liquid containing the comminuted soy beans was pumped by way of 147 toes of two inch chrome steel holding tubing giving about 5 minutes residence time to complete the extraction. This liquid had a final temperature of 195° F and a pH of eight.5. The fact that the product of this course of has excessive stability throughout storage is shocking in gentle of the commonly held belief that exposing lipids to a hot alkaline answer results in saponification of the lipids.
Alternatively, the comminution can be carried out under stress adopted by venting to launch undesirable flavors and odors. Comminution underneath pressure has the benefit of accelerating the boiling level of the extraction resolution, thereby permitting extra severe treatment during the comminution step. This course of can be used with dehulled soy beans or deskinned peanuts, with or with out presoaking. This process additionally can be used with entire soy beans and whole peanuts which haven't been dehulled or presoaked, thereby eliminating the price of presoaking or dehulling related to other processes.
A process as claimed in declare 38 comprising the extra step of instantizing the powder. A process as claimed in declare 17 whereby the extraction resolution accommodates sodium hydroxide. A process as claimed in declare 17 comprising the additional step of instantizing the powder. A course of as claimed in declare 1 whereby the extraction solution accommodates sodium hydroxide. A process as claimed in claim 3 comprising the additional step of instantizing the powder.
No. 2,928,821 describes a method of producing a protein-lipid complex from vegetable material. Chayen states that the popular temperature of the liquid fed into the hammermill is about 45°-55° F. The comminution can occur beneath atmospheric stress, or in the presence of a vacuum to withdraw the risky elements responsive for the beany taste of soy bean products.
A course of as claimed in claim 1 wherein the extraction resolution temperature is at least about 205° F. A course of as claimed in declare 1 wherein the oilseed is soy beans. If a product in a powder form is desired, the clear extract from the cooling stage 18 can be despatched to the focus stage 20 and the spray drying stage 22. When the powder is meant to be used with liquids, it could be instantized within the instantizing stage 24. The extract is then cooled in the cooling stage 18 to prevent degradation of the seed materials extracts.
If a powder product is desired, the extract can be concentrated and spray dried utilizing typical means to yield a stabilized, full fats, excessive protein powder. This powder can be instantized utilizing conventional means to enhance the powder's dispersibility in aqueous solutions. A course of as claimed in declare 38 wherein the step of clarifying comprises the step of centrifuging. A process as claimed in declare 38 whereby the extraction solution temperature is at least about 205° F. A course of as claimed in declare 38 wherein the oilseed is soy beans.
The rest of the method comprises steps for concentrating and stabilizing the extracted carbohydrates, lipids and proteins within the extraction answer. This includes clarifying the neutralized comminuted oilseed/extraction resolution mixture in the clarification stage 14. Clarification can be done earlier than neutralization. A centrifuge is beneficial for undertaking the clarification step. Sludge, which consists primarily of the fibrous component of the oilseed is the byproduct of the clarification step.
These fat-free flakes are ready from entire soy beans by dehulling, rolling and hydrocarbon solvent extracting the soy beans. The extracted flakes are then steamed and heated to take away traces of solvent. The flakes are normally stored until wanted for extracting the protein.
Because of biscuit production line of the popular embodiment that are obvious to one skilled within the art, the spirit and scope of the appended claims shouldn't necesarily be restricted to the outline of the popular embodiment. EXAMPLE 2 Using the method of Example 1, whole shelled peanuts were successfully treated. The yield was 79.3%.
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 food product derived from complete soy beans comprising lipids and proteins whereby at least about 75% of the lipids are within the sure kind and ready by the process of claim 19. EXAMPLE 1 Commercial grade entire soy beans had been fed to a Fitz mill at 3.3 kilos per minute. The mill was operated with a # IA display screen, at an impression forward position.
