This invention discloses a method for identifying coconut oil based on MALDI-TOF mass spectrometry and a committee strategy, belonging to the field of analytical chemistry and food safety testing technology. The method includes: acquiring and preprocessing mass spectrometry data of the oil sample; extracting several characteristic peaks and their corresponding relative intensities from the mass spectrometry data; calculating the score of the oil sample based on the mass-to-charge ratio and intensity of the characteristic peaks; and identifying whether the oil sample is coconut oil based on its score. This invention optimizes the characteristic peak combination for coconut oil authenticity identification based on mass spectrometry combined with a committee strategy. The constructed machine learning classification model achieves 100% accuracy and an AUC value of 1 on the test set, solving the problems of incomplete feature extraction, instability of mass spectrometry signals, and peak drift interference in existing machine learning models, thus achieving accurate identification of edible oils. This invention has a wide range of applications and can be extended to the identification of other types of edible oils, exhibiting strong versatility and comprehensively covering the identification needs of the edible oil market.

The present application relates to the field of oil processing and edible special oil preparation, and particularly relates to a palm-free low-trans coconut oil-based shortening and a preparation method thereof, aiming at solving the problems of narrow plasticity temperature range, coarse crystallization and high proportion of saturated fatty acid of the existing coconut oil-based shortening. The shortening is prepared from physical refining coconut oil, high-oleic sunflower oil, fully hydrogenated rapeseed oil, high-oleic safflower oil, fully hydrogenated soybean oil, through step-by-step lipase catalytic transesterification, high-melting-point solid-phase separation, complex seed auxiliary medium-chain fatty acid adaptive natural antioxidant compounding and quenching kneading forming process. The present application realizes gradient controllable optimization of triglyceride structure through step-by-step use of sn-1,3 specific lipase and non-specific lipase, and designs a ternary natural antioxidant system according to the characteristics of medium-chain saturated fatty acid in coconut oil.

The present application relates to a kind of aerial prevention adjuvants and its preparation method and application, aerial prevention adjuvant includes adhesion promoter, synergist, compatible agent and dispersion medium, adhesion promoter includes oleyl ether and fatty alcohol random polyether;Synergist includes polyoxyethylene ether compound, fatty acid amide and polyethylene glycol fatty acid ester;Compatible agent includes first compatible agent, second compatible agent and third compatible agent, first compatible agent is selected from one or more of alkyl benzene sulfonate, alkyl sulfonate, alkyl sulfonate, alkyl sulfate, second compatible agent is selected from one or more of fatty alcohol polyoxyethylene ether sulfate, fatty alcohol polyoxyethylene ether phosphate, and third compatible agent is polyethylene glycol-5 coconut oil base methyl ammonium sulfate.The aerial prevention synergist provided by the present application has good applicability, can effectively improve the performance of pesticide solution, increase the rainwater scouring resistance of pesticide on target, weaken the adverse effects of rainfall on disease and pest control efficiency while improving the stability of various pesticide formulations and fertilizer mix.
