Embodiment 1

[0021] Example 1: Using soybean meal to carry calcium carbonate.

[0022] Nano-processing of food particles and nutrient adsorption: Take 100g of commercially available soybean meal powder, bake it until the water content is about 7%, mix it with 25g of light calcium carbonate superfine powder (with a particle size below 30um), mix it evenly, and grind it with a ball mill for 18 hours (The filling rate of the grinding medium is 60%) to the peak of the particle size distribution at about 300nm.

[0023] Preparation of nanofood clusters: Transfer the mixture to an airtight container and humidify to 100% relative humidity without liquid water. After oscillating for 24 hours, let it rest for 56 hours.

[0024] Packaging and storage: granulation, vacuum packaging. Stored at room temperature or low temperature, the shelf life is more than 3 months.

Embodiment 2

[0025] Example 2: Using flour particles to carry vitamin E.

[0026] Nanoprocessing of food particles and nutrient adsorption: Take 5g of common commercially available flour (dissolved in 30ml of 0.05mol / L acetic acid solution), add 0.2g of vitamin E (dissolved in 3mL of refined soybean oil, containing a small amount of sucrose ester) drop by drop, Stir vigorously, and then continue to add about 30ml of 0.05mol / L acetic acid solution until the solution system is relatively uniform and transparent. The solution was homogenized with a DeBEE ultra-high pressure dispersing homogenizer (mini DB) (pressure 200 MPa). After homogenization under this condition, the peak particle size of flour granules in the system can reach below 300nm.

[0027] Preparation of nano-food clusters: After the solution system was left to stand for 24 hours, the peak particle size of nano-food clusters was around 1340nm, reaching an equilibrium state.

Embodiment 3

[0029] Example 3: Using rice flour to carry vitamin D.

[0030] Nano-processing of food particles and nutrient adsorption: take 1g of rice flour passed through a 200-mesh sieve, adjust the mass ratio concentration to 0.5%, pH9, directly add 0.25g of vitamin D powder for ultra-high pressure dispersion and homogenization (pressure 40MPa).

[0031] Preparation of nano-food clusters: the mixture is heated to 85° C., cooled to 40° C. after 5 minutes, and the solution system reaches an equilibrium state after standing for 1 hour, and cooled to room temperature.

[0032] Packaging and storage: There is no obvious precipitation in the short-term standing solution. The solution system can be vacuum packed after spray drying and granulation. Stored at room temperature or low temperature, the shelf life is more than 3 months.

Abstract

The method of directly using ordinary food to construct a nutrient nano-carrying system is characterized by: (1) mixing food raw materials with a lipid content of less than 12% and nutrients at a mass ratio of 4-200:1, and then performing nano-processing, so that the particle diameter The distribution peak is below 600nm; (2) In the solution system, the concentration of the solution is adjusted to 0.5%-55% based on the quality of nano-food, and then the pH is adjusted to 2.2-13, and the ionic strength is converted to a sodium ion concentration of 0.001mol / L to 5mol / L, adopt ultrasonic oscillation of 0-65W / cm2, the temperature is 0-85°C, after 1-48 hours of aggregation process; or, in the solid state, control the temperature at 0-230°C and the pressure at 0.05-4MPa, The relative humidity is 0-100%, after 2-80 hours of accumulation; (3) Vacuum packaging, storage at room temperature or low temperature. The present invention wraps nutrients in nano-food clusters to realize the delivery of nutrients, improves stability, can be stored in liquid or solid state, can reduce or even avoid the degradation of nutrients, and has loose post-processing conditions; Greater improvement.

Description

technical field [0001] The invention belongs to the field of food processing. Background technique [0002] The study of nano-carrier system is one of the research hotspots in nanoscience. The study of oral nano-drug delivery system has brought great inspiration to food science to use nano-carriers to transport water-insoluble nutrients and promote their oral absorption. Nanocarriers can carry water-insoluble nutrients, improve their biological activity, and promote the absorption and utilization of these nutrients. For example, using chitosan-coated nanoliposomes to carry vitamin E and vitamin C, using casein micelles to carry vitamin D, etc. [0003] The nano-carrier system carries nutrients, which is restricted by the type of carrier. At present, there are many nano-carrier systems commonly used, mainly including inorganic nanoparticles (such as silicon particles, carbon nanotubes), polymer nanoparticles (such as polystyrene spheres), nanocapsules, liposomes, lipid mice...
