Abstract

The invention belongs to the technical field of food processing, and concretely relates to a processing method of normal temperature stored and transported mashed potato. The method comprises the following steps: cleaning fresh potatoes, peeling the cleaned potatoes, cutting the peeled potatoes to form 3-5 mm square blocks, carrying out extruding steaming cooking on the square blocks, allowing the sterilized and cooled cooked mashed potato to go through a closed aseptic filling machine, and filling and sealing the machine to realize normal temperature storage, transportation and selling. The processing method of the mashed potato, combining a double screw extruding boiling technology with an aseptic filling and sealing technology, changes the present production technologies of the mashed potato, is a high-efficiency processing method of the aseptic, cooked and normal temperature stored and transported mashed potato with long shelf life, and can solve the problems of flavor substance loss, high energy consumption and large logistics cost of present mashed potato production methods.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a processing method for storing and transporting mashed potatoes at normal temperature. Background technique [0002] Potatoes, also known as ground eggs, yams, potatoes, etc., are important food and vegetable crops and industrial raw materials. Due to drought tolerance, thin ridges, high and stable yields, wide adaptability, complete nutritional components and long industrial chains, they are highly regarded all over the world. Valuable and widely grown throughout the world. Potato seeds are rich in starch, protein, minerals and vitamins. In addition, they are also rich in dietary fiber. The effects of anti-aging, laxative and detoxification can be described as "perfect food". [0003] At present, my country's potato planting area has expanded to about 80 million mu, with a total output of more than 80 million tons, accounting for about 26% of the world's t...
