[0002] Rice noodles for infants and young children are supplementary food for infants when breast milk or infant formula cannot meet the nutritional needs of infants and during the weaning period. It mainly uses rice as the main raw material, white sugar, vegetables, fruits, eggs and meat as ingredients, and calcium Nutritious food prepared from minerals such as phosphorus, iron and vitamins, but rice noodles are easy to get angry, and the storage time is short after opening. At the same time, the existing rice noodles are directly added with trace elements during the preparation process. The adaptation content of the elements is different, and then different babies will have different characters after eating rice flour due to their different adaptability; at the same time, in order to improve the shelf life of rice flour, when adding chitosan, due to the greater cohesiveness of chitosan, And the dispersion performance is low, which makes the rice flour agglomerate and affects the antibacterial performance

Embodiment 1

[0022] The preparation process of antibacterial load agent is as follows:

[0023] Step 1: Add 481.6mg of ferric pyrophosphate and 17.8mg of zinc oxide into the acetic acid solution with pH=3, stir and dissolve at a constant temperature, and configure it as an adsorption solution;

[0024] Step 2: Add 1kg chitosan to 10L of the adsorption solution prepared in step 1, shake and react under the action of 29KHZ ultrasound at 35°C for 25-30h, and then measure the concentration of iron ions in the solution to be 0mg / L, and the concentration of zinc ions to be 0mg / L, it can be seen that zinc ions and iron ions are completely adsorbed, then evaporated to remove the solvent therein, and simultaneously washed with ethanol and dried to obtain an antibacterial loading agent.

Embodiment 2

[0026] The preparation process of antibacterial load agent is as follows:

[0027] Step 1: Add 484.3mg of ferric pyrophosphate and 18.1mg of zinc oxide into the acetic acid solution with pH=3, stir and dissolve at a constant temperature, and configure it as an adsorption solution;

[0028] Step 2: Add 1.03kg chitosan to the adsorption solution configured in 10L step 1, and shake and react for 25-30h under the action of 29KHZ ultrasound at 35°C, then measure the concentration of iron ions in the solution to be 0mg / L, and the concentration of zinc ions to be 0mg / L, it can be known that zinc ions and iron ions are completely adsorbed, and then evaporated to remove the solvent, washed with ethanol and dried to obtain an antibacterial loading agent.

Embodiment 3

[0030] The preparation process of antibacterial load agent is as follows:

[0031] Step 1: Add 450mg of ferric pyrophosphate and 15mg of zinc oxide into the acetic acid solution with pH=3, stir and dissolve at a constant temperature, and configure it as an adsorption solution;

[0032] Step 2: Add 1kg chitosan to 10L of the adsorption solution prepared in step 1, shake and react under the action of 29KHZ ultrasound at 35°C for 25-30h, and then measure the concentration of iron ions in the solution to be 0mg / L, and the concentration of zinc ions to be 0mg / L, it can be seen that zinc ions and iron ions are completely adsorbed, then evaporated to remove the solvent therein, and simultaneously washed with ethanol and dried to obtain an antibacterial loading agent.

Abstract

The invention discloses an infant nourishing rice flour capable of nursing intestinal tract. The infant nourishing rice flour comprises the following components in parts by weight: 70-75 parts of rice, 8-11 parts of rock sugar, 2.8-3.1 parts of whole milk powder, 18-23 parts of a medical and edible conditioning agent, 0.35-0.38 parts of an antibacterial loading agent, 0.41-0.42 parts of calcium carbonate, and 0.011-0.012 parts of a nutritional additive. A preparation method adds the antibacterial loading agent in the preparation process of the rice flour, the antibacterial loading agent improves the degradation efficiency of chitosan by ultrasonically degrading chitosan in an acid solution, the chitosan contains an amino group and a hydroxyl group, the amino group can adsorb iron and zincions in the solution, the hydroxyl group can adsorb a part of the zinc ions, so that the iron and the zinc ions are loaded on the chitosan, the chitosan is easily dissolved in water after being degraded, and the chitosan has certain antibacterial properties, the zinc ions also have certain antibacterial properties, the synergistic effect of the chitosan and the zinc ions makes the nutritious riceflour have higher antibacterial property, and the shelf life can be prolonged.
