Description

Preparation method for improving quality of rice
Technical Field
The invention belongs to the key technical field of grain processing, and particularly relates to a preparation method of rice.
Background
Rice is one of the important grains and is staple food for most people in China. The rice is rich in starch, protein, fat, vitamins and a large amount of essential trace elements such as iron, manganese, copper, zinc, selenium and calcium, and can provide rich nutrition for human bodies. The content of starch in rice is 60-70%, and during the cooking process of rice, the raw starch grains swell and break, and are combined with water molecules to form a viscous solution. Starch has a great influence on the taste of rice. During the low-temperature storage process, the rice is easy to age and has poor mouthfeel such as hardening, crisping and the like. This is because the hydrogen bonds between the starch molecules and the water molecules are broken, and the hydrogen bonds between the starch molecules are recombined, so that the starch molecules are rearranged into ordered crystals to precipitate, and simultaneously, the water in the starch colloid is gradually removed to generate the water-separating effect. The aged rice has reduced taste and influence on digestion and absorption. Therefore, the rice is pretreated by finding an effective means, so that the nutrition and the palatability of the rice are improved.
Disclosure of Invention
In order to solve the problems, the invention provides a preparation method for improving the quality of rice, which utilizes functional natural modifiers such as fructo-oligosaccharide, sorbitol and maltitol to perform ultrasonic-assisted soaking and cooking on rice, can effectively improve the taste and quality of the rice, obviously improves the anti-retrogradation property, and has better application prospect.
The preparation method for improving the quality of the cooked rice specifically comprises the following steps:
(1) elutriation and draining: selecting full-grain rice as a raw material, quickly washing the rice, and draining.
(2) Soaking: soaking the rice in the composite modifier and water, wherein the mass ratio of the rice to the composite modifier to the water is 1 (0.04-0.06) to 1.3-1.5, and then soaking by using ultrasonic assistance, wherein the ultrasonic power is 600-700w, and the time is 20-30 min.
The composite modifier comprises, by mass, 60-80% of fructo-oligosaccharide, 10-20% of sorbitol and 10-20% of maltitol.
Preferably, the mass ratio of the rice, the composite modifier and the water is 1: 0.05: 1.4.
(3) and (3) cooking: and (3) putting the rice, the water and the composite modifier in the step (2) into a steamer for steaming.
Has the advantages that:
compared with the traditional rice cooking process, the ultrasonic-assisted soaking of the functional natural modifiers such as fructo-oligosaccharide, sorbitol and maltitol on rice can improve the texture quality and the edible mouthfeel of the cooked rice, and the nutritional quality of the rice is improved due to the addition of the functional natural modifiers. The invention utilizes the synergistic effect of fructo-oligosaccharide, maltitol and sorbitol to change starch components, inhibit starch retrogradation, obviously improve the hardness and chewiness of rice and reduce the aging degree during storage.
