Description

1. Technical field [0001] The invention belongs to the technical field of food processing. 2. Background technology [0002] Dried nuts such as melon seeds, pecans, torreya, and pine nuts are rich in nutrients, and are one of the nutritious foods for modern people selected by the American "Time" magazine. Because these dried nuts are rich in oil components, most of which are polyunsaturated fatty acids, they are prone to autooxidative rancidity during processing and storage. Autooxidation refers to the spontaneous oxidation of oil when exposed to air for a long time. Oxidation can occur on the unsaturated bonds of oils and is more likely to occur in free unsaturated fatty acids. Oxidation of fats and oils produces mixtures of aldehydes, ketones, acids, etc., which change the properties and flavors of fats and oils. After the oil is oxidized and rancid, not only the smell and taste are bad, but also the essential fatty acids and vitamins in it are damaged and the nutritiona...
