Embodiment 1

[0034] Removal of impurities: take royal jelly and use deionized water to adjust the water content of royal jelly to 25%. If the water content of the royal jelly raw material is higher than 25%, there is no need to add deionized water for adjustment, and it can be used directly; then the royal jelly is over 100 After mesh sieving, test its isoelectric point, then adjust the pH to the isoelectric point of royal jelly, and then place the adjusted royal jelly in a refrigerator at a temperature of 2℃;

[0035] Carrier preparation: mix agar and water into an agar solution with a mass concentration of 10g / L, then mix the dilute acetic acid solution with a mass fraction of 3% and the agar solution at a mass ratio of 1:5 for 10 minutes, then pour it into the indentation In the mold, transfer the mold to a refrigerator at a temperature of 2°C and let it stand until it freezes into a concave-shaped gel sheet with a thickness of 1mm;

Embodiment 2

[0040] Removal of impurities: take royal jelly and use deionized water to adjust the water content of royal jelly to 27%. If the water content of the royal jelly raw material is higher than 27%, there is no need to add deionized water for adjustment, and it can be used directly; then the royal jelly is over 200 After mesh screening, test its isoelectric point, then adjust the pH to the royal jelly isoelectric point, and then place the adjusted royal jelly in a refrigerator at a temperature of 3℃;

[0041] Carrier preparation: agar and water are prepared into an agar solution with a mass concentration of 15g / L, and then a 4% dilute acetic acid solution and agar solution are mixed in a mass ratio of 1:8 for 50 minutes, and then poured into the indent In the mold, transfer the mold to a refrigerator at a temperature of 3°C and let it stand until it freezes into a concave-shaped gel sheet with a thickness of 1.5mm;

[0042] Pre-freezing: Put the royal jelly on the surface of the gel sh...

Embodiment 3

[0046] Removal of impurities: take royal jelly and use deionized water to adjust the water content of royal jelly to 30%. If the water content of the royal jelly raw material is higher than 30%, there is no need to add deionized water for adjustment, and it can be used directly; then the royal jelly is over 500 After mesh screening, test its isoelectric point, then adjust the pH to the royal jelly isoelectric point, and then place the adjusted royal jelly in a refrigerator at a temperature of 4℃;

[0047] Carrier preparation: mix agar and water into an agar solution with a mass concentration of 20g / L, and then mix a 5% dilute acetic acid solution and agar solution at a mass ratio of 1:10 for 60 minutes, then pour them In the mold, transfer the mold to a refrigerator at a temperature of 4℃ and let it stand until it freezes into a concave-shaped gel sheet with a thickness of 2mm;

[0048] Pre-freezing: Place the royal jelly on the surface of the gel sheet and pre-freeze it for 3 hour...

Abstract

The invention discloses a production method of a freeze-dried additive-free royal jelly powder product, and belongs to the technical field of health foods. The production method comprises the following steps: taking and sieving royal jelly, measuring the isoelectric point, and adjusting the pH value to the isoelectric point of the royal jelly; stirring and mixing dilute acetic acid and an agar solution, and freezing the obtained mixture to form a gel sheet with the thickness of 1-5 mm; flatly placing the royal jelly on the surface of the gel sheet, pre-freezing the royal jelly at a temperatureof -35 to-45 DEG C, and controlling the thickness of the obtained frozen royal jelly layer to be 15-20 mm; carrying out vacuum freeze drying on the pre-frozen royal jelly until the water content is 5-8%; carrying out vacuum freeze drying on the primarily dried royal jelly until the water content is 2% or below; and sealing and storing the secondarily dried royal jelly to finish the production ofthe freeze-dried additive-free royal jelly powder product. The method has the advantages of simple preparation process and low energy consumption, and the obtained product has stable physicochemical and biological properties.

Description

Technical field [0001] The invention discloses a method for preparing a zero-addition royal jelly freeze-dried powder product, which belongs to the technical field of health food. Background technique [0002] The full name of freeze-drying is vacuum freeze-drying, also known as sublimation drying, which is a contemporary method for dehydration and preservation of unstable substances. During freeze-drying, the dried substance is first frozen quickly at low temperature, and then the frozen water molecules are directly sublimated into water vapor and escaped in a proper vacuum environment without the process of ice water and hydration gas. During the sublimation process, condensation will not occur due to dehydration, avoiding side effects such as foaming and oxidation due to evaporation. After drying, the material is dry and porous, the volume is basically unchanged, and it is easily dissolved in water to restore to its original state, which prevents drying to the greatest extent ...
