Embodiment 1
[0031] The processing, packaging and storage method of pecans are carried out as follows:
[0032] (1) Raw material preparation: Harvest fully mature hickory nuts, remove the buds by a debrading machine, screen out the ones with full grains by the water flotation method, and drain them for later use;
[0033] (2) Preparation of seasoning liquid: first mix salt and Chinese prickly ash with a weight ratio of 10:1 to make a seasoning seasoning; then prepare a seasoning liquid with the seasoning and water at a ratio of 1:100 by weight and volume, and set aside;
[0034] (3) Steaming, frying and seasoning of raw materials: first steam the raw materials in step (1) at 121°C and 1.010 atmosphere pressure for 10 minutes, then steam at 100°C and normal atmospheric pressure for 2.5 hours, and then stir fry for 15 minutes with high heat. -25min until the fruit surface cracks; soak the cracked hickory nuts in the seasoning liquid of step (2) for 5-10min, then stir-fry until the fruit surf...
Embodiment 2
[0039] In this example, the seasoning is a 1:15 mixture of cream spices and sugar by weight; the pecan raw material is steamed at 121°C and 1.015 atmospheres for 10 minutes, and then steamed at 100°C and normal atmospheric pressure for 2.0 hours; the PE / Al The thickness of the / PE composite film is 90μm; the iron-based deoxidizer used is a mixture of iron powder, sodium sulfite and diatomaceous earth in a weight ratio of 3:1:3; the vacuum in the packaging bag is 0.095Mpa; the storage temperature of the bagged product is 10°C , the storage period is as long as 10-11 months; all the other processes and conditions are the same as in Example 1.
