The invention discloses a preparation method of a fructus
cannabis protein peptide product with effects of resisting fatigue and improving exercise ability, which comprises the following steps: performing preliminary crushing, ultralow-temperature freezing micro-crushing and low-temperature continuous phase-change extraction
degreasing on fructus
cannabis, performing step-by-step
hydrolysis by using polysaccharase and 2.4 L bacterial
protease to extract fructus
cannabis protein, performing low-temperature
salting-out, and performing freeze-
drying to obtain the fructus cannabis
protein peptide product with the effects of resisting fatigue and improving exercise ability. The fructus cannabis protein
peptide powder is prepared through low-temperature ultrasonic
dissolution promotion, high-pressure micro-jet homogenization, compound
enzyme C
hydrolysis, 1% pepsase, high-temperature
enzyme deactivation,
chlorophyll removal through counter-current extraction,
hydrogen peroxide decoloration, ultralow-temperature instantaneous concentration, low-temperature vacuum belt type
drying and low-temperature ultrahigh-pressure sterilization. The fructus cannabis protein peptide prepared by the invention has the following remarkable effects: 1, the exercise ability is remarkably improved, the accumulation of
lactic acid and
urea nitrogen is reduced, the exhaustion time is prolonged, and the physical and
mental fatigue is relieved; 2, the content of
hepatic glycogen and
muscle glycogen is obviously increased, the energy reserve of the body is increased, the
explosive power and the reactivity are improved, and the athletic performance is improved; and 3, the
antioxidant level of the body is improved, and fatigue and immune
recovery after exercise are promoted.
