Product Description
Here are the steps to make fortified rice using an extruder: ### 1. Raw Material Preparation - **Base Grains**: Select high - quality rice grains as the main raw material. You can also use a combination of different types of rice, such as long - grain, short - grain, or parboiled rice, depending on the desired texture and taste of the fortified rice. Additionally, you may include other grains like corn, wheat, or millet in small proportions to enhance the nutritional profile. - **Nutrient Fortificants**: Gather a variety of nutrients to fortify the rice. Common fortificants include vitamins (such as vitamin A, vitamin B complex, vitamin C, and vitamin E), minerals (like iron, zinc, calcium, and iodine), and other bioactive compounds like folic acid or lysine. These nutrients can be in the form of powders, granules, or premixes. - **Binders and Additives**: To improve the extrusion process and the quality of the final product, add binders such as starch (e.g., corn starch or tapioca starch), gums (like xanthan gum or guar gum), or proteins (e.g., soy protein isolate). Additives like lubricants (e.g., stearic acid) can help reduce friction during extrusion, and flavor enhancers can be used to maintain or improve the taste of the fortified rice. ### 2. Mixing of Ingredients - **Dry Mixing**: First, put the ground or milled base grains into a large mixer. Then, add the nutrient fortificants, binders, and other dry additives. Mix them thoroughly for about 10 - 15 minutes. The goal is to ensure an even distribution of all the components so that each particle of the final product contains a consistent amount of nutrients. - **Wet Mixing**: Slowly add water to the dry mixture while continuing to mix. The amount of water added typically ranges from 15 - 30% of the total mixture weight, depending on the type of raw materials and the extruder's requirements. The wet mixing process should continue for another 5 - 10 minutes until the mixture reaches a dough - like consistency that is suitable for extrusion. ### 3. Extrusion Process - **Extruder Setup and Pre - heating**: Clean the extruder thoroughly to remove any residues from previous operations. Then, set the temperature zones of the extruder according to the characteristics of the raw materials. For fortified rice production, the barrel temperature usually ranges from 120 - 180°C. The feed zone is set at a relatively lower temperature (around 120 - 130°C), and the die end is set at a higher temperature (160 - 180°C). Pre - heat the extruder for about 15 - 20 minutes to ensure that the temperature is stable. - **Feeding the Mixture**: Load the well - mixed raw material into the hopper of the extruder. The screw of the extruder will then convey the mixture forward through the barrel. As the mixture moves along the barrel, it is subjected to increasing pressure and heat. The combination of pressure and heat causes the grains to gelatinize, the binders to activate, and the nutrients to be incorporated into the matrix. - **Extrusion and Shaping**: The molten mixture is forced through a die with a shape similar to that of natural rice grains. The die design is crucial as it determines the size, shape, and appearance of the fortified rice. Some extruders may use a multi - hole die to produce multiple rice - like particles simultaneously. ### 4. Post - Extrusion Processing - **Drying**: The extruded fortified rice particles are usually moist and need to be dried to reduce their moisture content. Place the extruded rice on a conveyor belt or in a drying chamber. The drying temperature is typically set between 60 - 80°C, and the drying process may take several hours, depending on the initial moisture content and the thickness of the rice particles. Aim for a final moisture content of around 10 - 12% to prevent spoilage and ensure good storage stability. - **Cooling**: After drying, the fortified rice needs to be cooled to room temperature. This can be achieved by passing the dried rice through a cooling tunnel or allowing it to cool in a well - ventilated area. Cooling helps to harden the rice particles and makes them easier to handle. - **Quality Control**: Conduct various quality control checks on the fortified rice. Measure the size and shape of the particles to ensure they are consistent with the desired specifications. Analyze the nutrient content to verify that the fortified rice contains the required amounts of vitamins, minerals, and other nutrients. Also, check the taste, texture, and cooking properties of the rice to ensure it is acceptable to consumers. ### 5. Packaging and Storage - **Packaging**: Once the fortified rice passes the quality control tests, it is ready to be packaged. Use appropriate packaging materials such as plastic bags, paper bags with a moisture - proof lining, or sealed containers. The packaging should be air - tight to prevent moisture absorption, nutrient degradation, and contamination. - **Storage**: Store the packaged fortified rice in a cool, dry place away from direct sunlight. The storage temperature should be maintained at around 15 - 25°C, and the relative humidity should be kept low (below 60%) to ensure the long - term stability of the product.
Artificial rice refers to starch-like raw materials added with various nutrient fortification substances, artificially granulated, gelatinized, and dried to make granules similar to natural rice. The artificial rice is mixed with rice at a ratio of 1: 200 ~ 300, so that the nutritional value of the cooked rice after mixing is significantly better than that of ordinary rice.
Various vitamins, trace elements and proteins are added to solve the health problems caused by the lack of vitamins in the public. Ordinary grains will cause a lot of nutrient loss during the processing. Fortified vitamin B group and iron and other trace elements supplement or enrich the nutrients in rice, increase the deficiency of nutrients in food, and meet the requirements of nutrition and energy supply. Human nutrition is balanced, preventing disease and promoting health, and improving quality of life. Therefore, engineering rice is the most ideal new staple food in modern people's lives.
