Problems solved by technology

In this technology, spices are added to the prepared salt solution and processed by ultrasonic pulverization, which can accelerate the dissolution of active ingredients in spices, but the utilization rate of active ingredients in spices is not high; using pulsating pressure for pickling, the pickling speed is fast, but pickling It needs to be waxed and then cooked, and the process is complicated; there is no cleaning and decolorization process for pickled flavored salted eggs, and the finished salted eggs cannot maintain the orig

Abstract

The invention discloses a method for rapidly pickling salted eggs through ultrasonic waves. The method comprises the following steps of: weight grading, cleaning, pickling, decolorizing, cooking and packaging. Cleaning, pickling and decolorizing processes are integrated in one ultrasonic wave pickling pot, the less equipment is needed, the production efficiency is high, the product has good internal quality and good appearance color, and the method can be widely applied to the pickling of various eggs.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a method for quickly pickling salted eggs with ultrasonic waves. Background technique [0002] Salted egg is a traditional specialty food in my country. It is made of fresh eggs after pickling. It is rich in nutrients, rich in fat and protein, and the content of amino acids is higher than that of fresh eggs. It also contains calcium, phosphorus, iron and other minerals. Substances and vitamins are easily absorbed by the human body, suitable for all ages, and are deeply loved by consumers. The traditional pickling methods of salted eggs mainly include salt water immersion method, mud bag method and ash bag method. Because the salt water immersion method is easy to operate and penetrates evenly, it is the main method for large-scale processing of salted eggs. The traditional method of pickling salted eggs generally takes 30 days to 50 days, and the production efficiency i...
