Embodiment 1
[0030] A preparation method of coconut-flavored nutritious peanut oil, comprising the steps of:
[0031] (1) Raw material pretreatment: mix peanut kernels and coconut meat according to the weight ratio of 3:1, then add sodium chloride solution with a mass fraction of 0.8%, soak in ultrasonic for 2.5h, take out, rinse with cold water, and drain Standby; where the ultrasonic power density is 60-80W / L, and the ultrasonic frequency is 15-25kHz;
[0032] (2) Repeated freezing and thawing: Put the pretreated raw materials obtained in step (1) into a crushing equipment for crushing until they can pass through a 40-mesh sieve, freeze the crushed raw materials to -15°C to -20°C, and then place them at 40°C Thaw quickly, so repeated freezing and thawing 4 times;
[0033] (3) Low-temperature drying: dry the raw material obtained in step (2) by freezing and thawing at 40-60° C. until the moisture percentage in the raw material is 4-7%;
[0034] (4) Supercritical carbon dioxide extractio...
Embodiment 2
[0037] A preparation method of coconut-flavored nutritious peanut oil, comprising the steps of:
[0038] (1) Raw material pretreatment: Mix peanut kernels and coconut meat according to the ratio of 2:1 by weight, then add sodium chloride solution with a mass fraction of 0.5%, soak in ultrasonic for 2 hours, take out, rinse with cold water, drain and set aside ; The ultrasonic power density is 60-80W / L, and the ultrasonic frequency is 15-25kHz;
[0039] (2) Repeated freezing and thawing: Put the pretreated raw materials obtained in step (1) into a crushing equipment for crushing until they can pass through a 40-mesh sieve, freeze the crushed raw materials to -15°C to -20°C, and then place them at 40°C Thaw quickly, so repeated freezing and thawing 3 times;
[0040] (3) Low-temperature drying: dry the raw material obtained in step (2) by freezing and thawing at 40-60° C. until the moisture percentage in the raw material is 4-7%;
[0041] (4) Supercritical carbon dioxide extrac...
Embodiment 3
[0044] A preparation method of coconut-flavored nutritious peanut oil, comprising the steps of:
[0045] (1) Raw material pretreatment: mix peanut kernels and coconut meat according to the weight ratio of 5:1, then add sodium chloride solution with a mass fraction of 1%, soak in ultrasonic for 3 hours, take it out, rinse with cold water, drain and set aside ; The ultrasonic power density is 60-80W / L, and the ultrasonic frequency is 15-25kHz;
[0046] (2) Repeated freezing and thawing: Put the pretreated raw materials obtained in step (1) into a crushing equipment for crushing until they can pass through a 40-mesh sieve, freeze the crushed raw materials to -15°C to -20°C, and then place them at 40°C Thaw quickly, so repeated freezing and thawing 5 times;
[0047] (3) Low-temperature drying: dry the raw material obtained in step (2) by freezing and thawing at 40-60° C. until the moisture percentage in the raw material is 7%;
[0048] (4) Supercritical carbon dioxide extraction...
