preparation example Construction

[0031] According to the preparation method described in the preferred embodiment of the present invention, the sleeve temperature of the twin-screw extruder during high-temperature cooking is 40-80 degrees Celsius, the screw speed is 120-180 rpm, and the cutter speed is 800-1300 rpm.

[0032] S105: Extrude the material after high-temperature cooking and extrude it through the die hole, and cut it into a rice shape by a cutter;

[0033] In order to achieve the purpose of cutting rice grains of different sizes, the die hole of the extruder can be adjusted. The die hole is elliptical, with a major axis of 4-6 mm and a minor axis of 1.8-2.0 mm.

[0034] S106: Drying the cut and shaped rice with hot air in a fluidized bed.

[0035] The temperature of the fluidized bed hot air drying is 60-80 degrees Celsius, and the time lasts for 40-120 minutes.

[0036] S107: Sieve the hot-air dried rice and blend it with ordinary rice for preparation.

Embodiment 1

[0038] First, rice is pulverized into 80 mesh rice flour with a hammer mill, and the rice flour of weight ratio 62.0 and the powder of 5% DHA content of specific gravity 5.0 and the emulsifier (monoglyceride) of specific gravity 1.0 are accurately weighed, and these materials are Fully mixed in the conditioner to obtain mixture A;

[0039] Afterwards, add 135°C saturated steam to heat the mixture A, add water with a specific gravity of 22.0, mix thoroughly to make the temperature reach 90°C, and obtain material B.

[0040] Material B was extruded on a BCTG-60 twin-screw extruder under the following extrusion conditions: screw speed 140r / min, sleeve temperature 50°C, die plate outlet temperature 80°C, and water with a specific gravity of 10.

[0041] Material B is extruded through the die hole and cut into rice grains by the cutter. The long axis of the die hole is 4.8mm, the short axis is 1.5mm, and when the cutting knife speed is 750r / min, rice grains with a thickness of 1.7m...

Embodiment 2

[0048] Similar to Example 1, at first rice is ground into 80 mesh rice flour, after that, the rice flour of specific gravity 65.0 and specific gravity are the emulsifier (monoglyceride) of 15% DHA content of 2 and specific gravity 1.5, Fully mixed in the container to obtain mixture A;

[0049] Add 135°C saturated steam to heat the mixture A, add 19.5% water, mix thoroughly to make the temperature reach 92°C, and obtain material B.

[0050] The material B was extruded on a BCTG-60 twin-screw extruder, and the extrusion conditions were: screw speed 160r / min, sleeve temperature 55°C, die plate outlet temperature 95°C, and water addition 12.

[0051] Material B is extruded through the die hole and cut into rice grains by the cutter. When the long axis of the die hole is 6.8mm, the short axis is 1.3mm, and the cutting knife speed is 850r / min, the rice grains with a thickness of 1.5mm can be cut. Similar to regular long grain rice.

[0052]The cut and shaped rice grains are sent t...

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 [0001] The invention relates to the field of nutritional food processing, in particular to DHA-enhanced rice and a preparation method thereof. Background technique [0002] As the most important staple food in the world, rice plays an irreplaceable role in the daily diet. The energy it provides can reach 40% in southern my country, and it can even account for more than 50% of daily energy intake in other Asian countries. [0003] With the improvement of people's living standards, people's nutritional requirements for staple food are also getting higher and higher. They are not satisfied with the requirement that rice is only used as a staple food to provide energy, and they are full of more expectations for its rich nutrition. [0004] DHA, docosahexaenoic acid, commonly known as brain gold, is a polyunsaturated fatty acid that is very important to the human body and is an important member of the Omega-3 unsaturated fatty acid family. DHA is a main element f...
