According to embodiments, a method for predicting quantitative measures of oil adulteration of an edible oil sample is provided. The method includes receiving at least part of a spectral data of the edible oil sample; providing a single prediction model capable of generating a prediction of an adulterant in the edible oil sample, wherein the single prediction model is a non-linear model including a deep neural network; and processing the at least part of the spectral data using the single prediction model. According to further embodiments, a computer readable storage medium including computer readable instructions operable when executed by a computer to predict quantitative measures of oil adulteration of the edible oil sample is also provided. According to yet further embodiments, an apparatus or system for predicting quantitative measures of oil adulteration of the edible oil sample is provided.
摘要:
The method for determination of content of hydrophobic compounds in water-miscible organic liquids is based on the segregation of hydrophobic compounds contained in organic liquids after their mixing with water in form of discrete, relatively stable nanoparticles, whose number concentration, size, and density correlate with the hydrophobic compounds content, which is subsequently quantified by calibration curves. The laser light scattering method can be used for such quantification. The advantage of the method is a low equipment price, a low single- measurement price, its compactness/use in the field, and mainly its appropriateness for use as a screening method.
摘要:
A sensing scheme comprising determining the chemical degradation and physical degradation in oil using variation in transmission behavior of oil for multi- wavelength electromagnetic radiation, and separating the contributory effect of physical degradation from the chemical degradation is disclosed. Further sensor designs employing the said scheme are disclosed.

Herein are disclosed are systems for optical monitoring of oil quality. The systems comprise a dispensing device and a cradle adapted to receive the dispensing device. The dispensing device contains a supply of test strips and comprises a mechanism for extending a test strip out of the dispensing device so that it can be contacted with an oil sample. The systems further comprise an interrogation module for optically interrogating at least one test zone of the test strip, so as to monitor at least one parameter of the oil sample. In one embodiment, the monitored parameter is the free fatty acid content of the oil, and the optical interrogation is performed by an optical reflectance method.
摘要:
A method and apparatus for measuring the chemical lean content of meat in which gas or air as a buoying fluid is used to carry out the measurement of meat density for the purposes of measuring chemical lean content of the meat. The method includes the step of direct measurement of the density of the buoying fluid. It is thus possible to overcome adiabatic issues and to speed up the cycle time of successive measurements.
摘要:
A method of assaying the antioxidant activity of a range of plant, animal or synthetic oils and other similar substances in a liquid phase. The method consists in forming an oil-in-water emulsion with a surfactant, adding an ethene generator substrate and an oxidative peroxyl radical solution and measuring the ethene produced by a flow tube technique or atmospheric chemical ionisation methodology.
