A kind of processing method of potato rice cake

Abstract

The invention discloses a processing method of potato rice cakes. According to the processing method, by optimizing the proportion of the fresh potatoes, rice and water, fresh potatoes serving as raw materials are directly ground and squeezed into rice cakes. On the one hand, compared with a common method utilizing dried potatoes or potato powder, the method has the advantages that the nutritional ingredients in the potatoes are retained well; and on the other hand, a preparation process of the rice cake is greatly simplified, i.e., the raw materials which are evenly mixed are added all together into a feeding hopper of grinding and extruding equipment and then are ground and squeezed via utilization of mechanical heat energy generated in an extruding process so as to directly obtain the cooked rice cakes, so that the finished product rice cakes can be obtained after the optimizing and subpackaging are carried out. The method is simple in process; the preparation cost is saved and the nutrition and the flavor of the potatoes are maintained to the greatest extent. Thus, the method disclosed by the invention is especially suitable for industrial mass production of the rice cakes.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method for processing potato rice cakes. Background technique [0002] Potatoes have high nutritional value and are globally recognized as a complete nutritional food, which has attracted extensive attention and research. Generally speaking, fresh potatoes contain about 9-20% starch, 1.5-2.3% protein, 0.1-1.1% fat, and 0.6-0.8% crude fiber. Potato protein has high nutritional value, high digestibility, and is easily absorbed by the human body. Its quality is similar to that of animal protein and comparable to that of eggs. Potato protein contains 18 kinds of amino acids, including arginine, histidine, isoleucine, lysine, methionine, phenylalanine, threonine, tyrosine, valine, etc. essential amino acids. In addition, potatoes are also rich in vitamins, including carotene, vitamin C, thiamine, riboflavin, niacin, etc., as well as minerals such as calcium, phosphorus, and iron. ...

Problems solved by technology

[0004] However, due to various factors, the processing and utilization of potatoes in my country is far behind developed countries at present, and the product form, key processing technology and equipment are mainly copied from foreign countries, especially the lack of Chinese consumers who use potatoes as raw materials. traditional food

Rice cake is a traditional food in my country. General rice cakes are refined with glutinous rice and sucrose as raw materials, but they are often of a single variety and not rich in nutrients. The development of rice cake processing technology with fresh potatoes as raw materials will improve the dietary structure of Chinese residents. , increase the consumption of potatoes, and promote the development of the potato industry, which plays an important role in ensuring my country's food security, ensuring the stable development of the national economy and "agriculture, rural areas and farmers". Carrying out the research and development of potato staple food processing technology and equipment is of great social importance. and economic significance
