Abstract

The invention relates to the technical field of plant oil processing, in particular to a tea seed cold-pressing oil producing method. The tea seed cold-pressing oil producing method comprises the following steps that impurities are removed from tea seeds, the tea seeds are cleaned and air-dried and then are fed into a freezing chamber and are frozen to reach -30 to -35 DEG C, the frozen tea seedsare fed into an ultrasonic groove, negative ion water is added, an ultrasonic generator is started to produce an ultrasonic effect, drying is performed, oil is extruded out, modified konjak grains areadded, and stirring and filtration are performed to obtain refined tea oil. By adopting the tea seed cold-pressing oil producing method, tea seed oil is obtained. The tea seed cold-pressing oil producing method has the advantages of being high in oil yield, low in nutrition loss rate and the like, and the produced tea oil meets the first-class tea oil standards on the standard aspects of color and luster, smell, transparency, acid value, peroxided value and the like.

Description

technical field [0001] The invention relates to the technical field of vegetable oil processing, in particular to a method for producing tea seed oil by cold pressing. Background technique [0002] Camellia oleifera is a unique oil tree species in China, and its fruit can extract important natural green organic health-care edible oil-camellia oil. A comparative study of tea oil and olive oil by the Institute of Nutrition and Food Safety of the Chinese Center for Disease Control and Prevention showed that tea oil and olive oil Despite the similarities in the composition of olive oil, the therapeutic dual function of tea oil is actually better than olive oil, and better than any other oil. Olive oil contains 75%-90% unsaturated fatty acids, and tea oil contains 85%-97% unsaturated fatty acids, which is the crown of all kinds of edible oils. Camellia oil contains specific physiologically active substances tea polyphenols and camellia glycosides that are not found in olive oil,...
