Embodiment 1

[0017] Wash 3000g of kiwi fruit with deionized water, pulverize and beat with a mixer, pass through a 100-mesh sieve, and extract 3 times with water at a temperature of 75°C at a solid-to-liquid mass ratio of 1:20, the first time for 3 hours, and the second time 2 hours for the first time, 1 hour for the third time, combine the water extracts for 3 times, and centrifuge at 2000 rpm for 10 minutes. After discarding the precipitate, filter it with a 100-mesh filter cloth to obtain the filtrate, and concentrate the filtrate under reduced pressure to a relative density of 1.00 (70°C), freeze-dry the concentrate at -30°C for 96 hours to obtain 53.15 g of kiwi fruit extract.

Embodiment 2

[0019] Wash 3000g of kiwi fruit with deionized water, pulverize and beat with a mixer, pass through a 200-mesh sieve, press the solid-to-liquid mass ratio of 1:40, and the temperature is 85°C, water extraction 2 times, the first time for 3 hours, the second time After 2 hours, the water extracts were combined twice, centrifuged at 3000 rpm for 15 minutes, and the precipitate was discarded, then filtered with a 200-mesh filter cloth to obtain the filtrate, and the filtrate was concentrated under reduced pressure to a relative density of 1.20 (80°C). The concentrate was freeze-dried at -60°C for 72 hours to obtain 40.22 g of kiwi fruit extract.

Embodiment 3

[0021] Wash 4000g of kiwifruit, crush it with a mixer, and extract it with water at 80°C for 3 times at a ratio of solid-liquid mass ratio of 1:30. Centrifuge for 15 minutes per minute, discard the precipitate, and then filter with a 200-mesh filter cloth to obtain the filtrate; concentrate the filtrate under reduced pressure at 60°C~80°C to a relative density of 1.00~1.20, and then filter it at -30~-60 It can be obtained after lyophilization at ℃ for 72~96 hours.

[0022] In order to prove whether the kiwifruit extract of the present invention has the function of improving memory, the new application will be shown through the following experiments:
