Abstract: A method for extracting oils from sauces while simultaneously determining fat content, peroxide value, and acid value is disclosed. The method is simple to operate and requires uncomplicated equipment. It features a short testing cycle and high efficiency, and suitable for the extraction of oils from oil-rich emulsified encapsulated sauces (such as salad dressings) with high extraction rates. The determination of peroxide value and acid value is not affected by pretreatment methods, ensuring more representative results. It addresses the challenges of difficult oil separation and extraction from oil-rich emulsified encapsulated sauces and solves significant issues encountered when using acid hydrolysis and alkaline hydrolysis methods to determine peroxide value and acid value. It enables the simultaneous monitoring of three physicochemical indicators (fat content, peroxide value, and acid value).

Abstract: The present invention discloses an SMA wire-driven reusable release mechanism having a self-resetting function. The present invention adopts a structure of two-stage load reduction and one-stage release. First-stage load reduction: a compression rod and a hoop petal, as well as an inclined block and a shell or a sliding block, all cooperate with each other by means of inclined surfaces, which can transfer most of tension load of the compression rod to the shell, leaving only a small part of the load transmitted to a thrust bearing. Second-state load reduction: balls in the thrust bearing are coated with a molybdenum disulfide lubricating coating, which can effectively reduce friction so as to reduce a torque transmitted to a driving shaft. First-stage release: the driving shaft drives a thrust bearing to rotate by a certain angle, causing an upper ring of the thrust bearing to descend to release a certain axial clearance.
