Embodiment 1
[0041] (1) soak ripe, complete, non-rotten, non-mildewed Yunnan olive fruit with 0.1wt% hydrogen peroxide aqueous solution for 10 minutes, rinse with clear water, remove the core with a pitting machine, and slice;
[0042] (2) The sliced Yunnan olive fruit is freeze-dried at -20°C and 30Pa using a vacuum freeze-drying machine to obtain a dried Yunnan olive fruit with a water content of 15% by weight;
[0043] (3) Grinding the obtained dried product at -10°C to a D50 of about 45 microns to obtain Yunnan olive powder.
Embodiment 2
[0045] (1) soak ripe, complete, non-rotten, non-mildewed Yunnan olive fruit with 0.5wt% hydrogen peroxide aqueous solution for 3 minutes, rinse with clear water, remove the pits with a pitting machine, and slice;
[0046] (2) The sliced Yunnan olive fruit is freeze-dried at -40° C. and 150 Pa using a vacuum freeze-drying machine to obtain a dried Yunnan olive fruit with a water content of 5 wt %;
[0047] (3) Grinding the obtained dried product at -40°C to a D50 of about 45 microns to obtain Yunnan olive powder.
Embodiment 3
[0049] (1) soak ripe, complete, non-rotten, non-mildewed Yunnan olive fruit with 0.6wt% hydrogen peroxide aqueous solution for 5 minutes, rinse with clear water, remove the core with a pitting machine, and slice;
[0050] (2) The sliced Yunnan olive fruit was pre-frozen at -80° C. for 8 minutes with a vacuum freeze-drying machine, and then freeze-dried at -10° C. and 100 Pa to obtain a dry product with a water content of 10 wt%.
[0051] (3) Place the obtained dry product in a low-temperature ultrafine pulverizer, and ultrafinely pulverize it to a D50 of about 5 microns at -20° C. to obtain Yunnan olive powder.
