Abstract
The invention provides a DHA fortified rice and a preparation method thereof. The DHA fortified rice comprises the following compositions in percentage by weight: 53 to 73.5 percent of rice flour, 25 to 40 percent of water, 1.0 to 5.0 percent of DHA preparation and 0.5 to 2.0 percent of emulsifier. The DHA fortified rice integrates the DHA nutrition and the rice into a food with the appearance being similar to ordinary rice, can be cooked like ordinary rice, and increases the nutrition value without changing the appearance and the taste.
Description
Technical field
The present invention relates to the nutraceutical manufacture field, be specifically related to a kind of DHA and strengthen rice and preparation method thereof.
Background technology
Rice occupies irreplaceable effect as most important staple food in the world wide in diet, its energy that provides can reach 40% in China south, and in Asia other countries in addition can account for that daily energy takes in more than 50%.
And along with the raising of people's living standard, people are also more and more higher to the nutritional requirement of staple food, and being not content with rice only is the requirement that energy is provided as staple food, and it nutritiously also has been full of more expectation.
DHA, DHA is commonly called as brain gold, is a kind of to the very important polyunsaturated fatty acid of human body, belongs to the important member in the Omega-3 unrighted acid family.DHA is a kind of essential element that nervous system cell is grown and kept, and is brain and amphiblestroid important composition composition, and content is up to 20% in the human brain cortex, proportion maximum in eye retina, account for 50%, therefore, grow most important tire infant intelligence and eyesight.
Existing DHA or use to people as medicine, fish oil for example, but its particle is bigger, is not easy to eat, as nutriment, for example brain gold or similar products like cost an arm and a leg, and it is edible to be unsuitable for the daily breakfast, lunch and dinner of people, for this reason, how to provide a kind of can be with DHA as the product in the diet, not only convenient but also easily, become the problem of nutrition circle joint research.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of DHA and strengthen rice, do not satisfy the problem that rice contains the DHA nutritional labeling to solve in the existing food.
