Embodiment 1
[0025] 1) add 30 times of water by weight in pomelo peel, supersonic treatment 15 minutes, then add the compound enzyme (cellulase) that is made up of cellulase and pectinase in grapefruit peel and water mixture by 0.2% of pomelo peel quality The mass ratio of pectinase to pectinase is 1.5:1), stirring and incubating at pH 4.8 and temperature 50°C for 20 hours to enzymatically hydrolyze pomelo peel, and then conduct steam distillation for 8 hours to collect volatile oil;
[0026] 2) Continue to heat and reflux the remaining aqueous solution of pomelo peel residue for 2.5 hours, suction filter, add 5% arginine and 8% fructose accounting for the mass of pomelo peel to the filtrate, adjust the pH to 9 with ammonia water, and heat to 105 Carry out the Maillard reaction at ℃ for 6 hours, concentrate to a brown extract with a relative density of 1.15, and obtain the grapefruit peel water extract Maillard reaction product;
[0027] 3) Add 85% (mass concentration) ethanol to the pomel...
Embodiment 2
[0030] 1) add 10 times of water by weight in pomelo peel, supersonic treatment 20 minutes, add the composite enzyme (cellulase) that is made up of cellulase and pectinase in grapefruit peel and water mixture by 0.1% of grapefruit peel weight then The mass ratio of pectinase to pectinase is 2:1), stirring and incubating at a pH of 4 and a temperature of 60° C. for 10 hours to enzymatically hydrolyze grapefruit peel, and then conduct steam distillation for 5 hours to collect volatile oil;
[0031] 2) Continue to reflux the remaining aqueous solution of grapefruit peel residue for 2 hours, suction filter, add glycine accounting for 4% of grapefruit peel mass and 10% glucose to the filtrate, adjust the pH to 10 with ammonia water, and heat to 90°C for plumbing Rad reaction for 8 hours, concentrated to a brown extract with a relative density of 1.1, to obtain the grapefruit rind water extract;
[0032] 3) adding 95% ethanol to the pomelo peel residue after suction filtration in ste...
Embodiment 3
[0035] 1) Add 40 times of water by weight in grapefruit peel, ultrasonic treatment 10 minutes, then add the compound enzyme (cellulase and pectinase) that is made up of cellulase and pectinase in 0.3% grapefruit peel and water mixture water of grapefruit peel weight The mass ratio of pectinase is 0.5:1), stirring and incubating at a pH of 6 and a temperature of 30° C. for 24 hours to enzymolyze the pomelo peel, and then carry out steam distillation for 10 hours to collect volatile oil;
[0036] 2) Continue to reflux and extract the remaining pomelo peel residue aqueous solution for 3 hours, suction filter, add isoleucine and 4% honey accounting for 10% of the pomelo peel mass to the filtrate, adjust the pH to 8 with ammonia water, and heat to 120 The Maillard reaction was carried out at ℃ for 4 hours, concentrated to a brown extract with a relative density of 1.2, and the grapefruit peel water extract Maillard reaction product was obtained;
[0037] 3) adding 70% ethanol to th...
