Embodiment 1

[0009] Take 100ml of 10% propolis alcohol solution, stir and add 20g of melted polyethylene glycol 6000 under the condition of 60°C water bath, add 1g of lecithin after continuous stirring for 10 minutes. Continue to stir for 5 minutes, then ultrasonically vibrate for 30 minutes, and immediately freeze at -30°C for 2 hours. Freeze drying is then performed. The freeze-dried propolis was dissolved in 50 times of water and then filtered with a 0.2 μm microporous membrane. The filtrate is the nano-propolis liquid, which can be used as a raw material for soft capsules or oral liquids. The filtrate can be dried by vacuum rotary evaporation or freeze-dried to obtain nano-scale propolis powder, which can be used as a raw material for hard capsules or granules.

Embodiment 2

[0011] Take 100ml of 20% propolis alcohol solution, stir and add 10g of melted polyethylene glycol 6000 under the condition of 70°C water bath, add 0.5g of lecithin after continuous stirring for 10 minutes. Continue to stir for 5 minutes, then ultrasonically vibrate for 30 minutes, and immediately freeze at -30°C for 2 hours. Freeze drying is then performed. The freeze-dried propolis was dissolved in 20 times of water and filtered with a 0.2 μm microporous membrane. The filtrate is the nano-propolis liquid, which can be used as a raw material for soft capsules or oral liquids. The filtrate can be dried by vacuum rotary evaporation or freeze-dried to obtain nano-scale propolis powder, which can be used as a raw material for hard capsules or granules.

Embodiment 3

[0013] Take 100ml of 15% propolis alcohol solution, stir and add 10 grams of melted polyethylene glycol 6000 under the condition of 80°C water bath, add 5g of lecithin after continuous stirring for 10 minutes. Continue to stir for 5 minutes, then ultrasonically vibrate for 30 minutes, and immediately freeze at -30°C for 2 hours. Freeze drying is then performed. The freeze-dried propolis was dissolved in 40 times of water and filtered with a 0.2 μm microporous membrane. The filtrate is the nano-propolis liquid, which can be used as a raw material for soft capsules or oral liquids. The filtrate can be dried by vacuum rotary evaporation or freeze-dried to obtain nano-scale propolis powder, which can be used as a raw material for hard capsules or granules.

Abstract

A nano-class propolis product used to prepare softgel, capsule or infusion is prepared through stirring the alcohol solution of propolis while adding fused polyethanediol 6000 by water bath at 60-80 deg.C stirring, adding lecithin, stirring, ultrasonic vibration, freeze drying, dissolving it in water, filtering by millipore membrane and evaporating drying or freeze drying.

Description

technical field [0001] The invention belongs to the field of health food preparation technology, and relates to a preparation method of propolis products, in particular to a preparation method of nano propolis products. Background technique [0002] Propolis is a natural product with the same source of medicine and food. It is a solid colloidal substance with aromatic stickiness formed by collecting worker bees from the new buds or bark of trees and other plants, and mixing it with bee mandibular gland secretions and beeswax. . Its main components are flavonoids, terpenes, aldehydes and ketones, esters and organic acids. A large number of studies at home and abroad have confirmed that propolis has many health care functions: broad-spectrum antibacterial and anti-inflammatory effects, enhanced antibody immunity, good antioxidant capacity, and can regulate blood lipids, blood pressure and blood sugar. However, because the main functional components of propolis, flavonoids an...
