Problems solved by technology

The common disadvantage of these two processes is that due to the cold water discrete process, the nutrients in the cooked millet are lost, which is the main reason for the lack of viscosity of the rice soup after the product is rehydrated, the soup is thin and watery, and the flavor is flat; The instant millet porridge made by hot air drying still suffers from serious shrinkage during the drying process, resulting in low rehydration rate, long rehydration time, and hard taste of the product; the instant millet porridge made by freeze-drying has too loose structure, and after rehydration, the instant millet porridge is too loose. The chewing strength of millet is not enough
In recent years, the convenient millet porridge processing technology developed after high-pressure cooking and vacuum freeze-drying as the main technology has better solved the problems of large nutrient loss, poor product rehydration, flat flavor and insufficient viscosity during processing. Easy to stick, the appearance of the product is not good enough

Abstract

The invention belongs to the field of food processing, and in particular provides convenient millet porridge and a preparation method thereof. The convenient millet porridge is prepared by using high-quality millets as main raw materials through material selecting, soaking, ultrasonic pretreating, microwave pre-cooking, centrifugal dewatering, superheated steam puffing, freeze drying and quantitative packing. The common problems of great nutrition loss, poor rice grain integrity, non-ideal rehydration comprehensive quality and the like in the convenient millet porridge processing process are solved; the prepared product has the advantages of light yellow color and luster, inflated and complete grain, attractive form, good rehydration performance and excellent favor. The processing process is reasonable; the popularization is easy and the expected economic and social benefits are good.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a convenient millet porridge and a preparation method thereof. Background technique [0002] Millet has a smooth and delicate appearance, high carbohydrate and protein content, and also contains vitamins such as carotene and vitamin B1. It has the characteristics of high energy and rich nutrition. "Compendium of Materia Medica" states that millet "cures nausea, cooks porridge, benefits the dantian, nourishes deficiency, and opens the stomach." Traditional Chinese medicine believes that millet also has the effects of clearing away heat and detoxification, nourishing the stomach and sleeping, so millet is an ideal natural tonic. There is the habit of eating millet porridge in the north of my country. In recent years, in the vast southern regions, the crowd of eating millet porridge has gradually increased. With the rapid development of my country's national economy and t...
