Expeller pressing (also called oil pressing) is a mechanical method for extracting oil from raw materials. The raw materials are squeezed under high pressure in a single step. When used for the extraction of food oils, typical raw materials are nuts, seeds and algae, which are supplied to the press in a continuous feed. As the raw material is pressed, friction causes it to heat. In the case of harder nuts (which require higher pressures) the material can exceed temperatures of 120 °F (49 °C).

Processing method of purple potato clear juice with high anthocyanin content
The invention relates to a processing method of purple potato clear juice with a high anthocyanin content. The processing method comprises the following steps: (1), processing raw materials: crushing raw materials, and adding the crushed raw materials with water to form potato pulp; (2), stewing the potato pulp: heating the purple potato pulp to be 70-80 DEG C, and carrying out heat preservation for 30-60 min; (3), carrying out pulp enzymolysis: cooling the pulp to be 50-55 DEG C, and adding amylase and potato pulp enzymes for enzymolysis for 1-2 h; (4), squeezing: after pulp enzymolysis, squeezing the pulp with a squeezer to obtain purple potato raw juice; (5), carrying out raw juice enzymolysis: heating the purple potato raw juice, cooling, and adding pectinase and amylase for enzymolysis for 1-2 h; (6), carrying out ultrafiltration; (7), concentrating. The processing method is characterized in that citric acid is added so as to regulate the pH value to be 3.0 when the raw materials are crushed, so that anthocyanin components in purple potatoes can be effectively protected, and nutritional ingredients in purple potatoes can be retained; the potato pulp is heated to be 70-80 DEG C for low temperature gelatinization, therefore gelatinization is ensured while the loss of anthocyanin is avoided, and through potato pulp enzymolysis and raw juice enzymolysis, starch in purple potatoes is fully converted into sugar, the utilization ratio of the raw materials is increased, and the purple potato concentrated clear juice which is rich in nutrition and stable in quality is further obtained through processing.
