Embodiment 1
[0038] A preparation method for debittering and detoxifying bitter almonds, comprising the steps of:
[0039] 1) Preparation of dry almond petals: immerse bitter almonds in a sodium bicarbonate solution with a concentration of 0.08% by mass, rinse at room temperature, drain, put in a container to seal, let it stand for moistening for 3 hours, and peel off the peeled almond petals. Freeze at -23°C, material layer thickness 3cm for 2 hours, take it out, microwave pre-drying for 3 minutes to get pre-dried almond petals; add 3 times its mass of citric acid solution with a mass percentage concentration of 0.2%, soak at room temperature for 3 hours, take it out, and put it on a stainless steel screen Clean water circulation and spray for 15 minutes, then transfer to 2.2% calcium ascorbate solution with twice the weight of pre-dried almond petals, soak for 4 hours, drain, microwave dry for 6 minutes to obtain dry almond petals;
[0040] The microwave pre-drying conditions are: freque...
Embodiment 2
[0050] A preparation method for debittering and detoxifying bitter almonds, comprising the steps of:
[0051]1) Preparation of dry almond petals: immerse bitter almonds in a sodium bicarbonate solution with a concentration of 0.06% by mass, rinse at room temperature, drain, put in a container to seal, let it stand for moistening for 2 hours, and peel the peeled almond petals in -20°C, material layer thickness 2cm, freeze for 1.5h, take it out, microwave pre-drying for 2min to get pre-dried almond petals; add twice its mass of 0.1% citric acid solution, soak at room temperature for 2h, take it out, put it on a stainless steel sieve Circulate and spray clean water on the net for 10 minutes, then transfer to 1.5% calcium ascorbate solution of 1.5% by mass of pre-dried almond petals, soak for 3 hours, drain, and microwave dry for 4 minutes to obtain dried almond petals;
[0052] The microwave pre-drying conditions are: frequency 2450MHz, power 1000W, temperature 80°C, material lay...
Embodiment 3
[0062] A preparation method for debittering and detoxifying bitter almonds, comprising the steps of:
[0063] 1) Preparation of dry almond petals: immerse bitter almonds in 0.1% sodium bicarbonate solution by mass percentage, rinse at room temperature, drain, put in a container to seal, let it stand for moistening for 4 hours, and peel the peeled almond petals in -25°C, material layer thickness 4cm, freeze for 2.5h, take it out, microwave pre-drying for 4min to get pre-dried almond petals; add 4 times its mass of 0.3% citric acid solution, soak at room temperature for 4h, take it out, put it on a stainless steel sieve Spray and wash with clean water on the net for 20 minutes, then transfer to a calcium ascorbate solution with a mass percentage concentration of 3% of the pre-dried almond petals, soak for 5 hours, drain, and microwave dry for 8 minutes to obtain dried almond petals;
[0064] The microwave pre-drying conditions are: frequency 2450MHz, power 1500W, temperature 90°...
