Abstract： Nut foods are rich in high-quality protein，unsaturated fatty acids，and a variety of vitamins and minerals，butthe problem of nutritional loss during processngcannot be ignored.Combining the characteristics of nut processing technology，this article analyzes the problems of vitamin degradation caused by high-temperature baking， oil oxidation caused by mechanical treatment，and changes in nutritionalcomponents during packaging and storage. In response to these problems， solutions such as segmented heating baking processlow-temperature cold pressing and crushing technology，and multi-layer composite packaging materials are proposed. By optimizing temperature and time parameters，reducing mechanical action intensity，and improving packaging and storage environment， the loss of nutrients can beefectivelyslowed down，the nutritional value and quality safetyof nut fods can be guaranteed，and consumers’ demand for healthy food can be met.
