Crispy instant codonopsis pilosula and preparation method thereof

Abstract

The invention discloses crispy instant codonopsis pilosula and preparation method thereof. The method comprises the following steps: taking fresh codonopsis pilosula which is quickly washed clean, drying in the shade for 3-15 days until the water content is 50-65%, cutting into sections, performing grading and freezing, setting the vacuum frying temperature to be 95-115 DEG C, keeping the temperature of circulating cooling water to be 5-15 DEG C, frying frozen codonopsis pilosula sections for 23-45 minutes when the vacuum degree reaches -0.092 to -0.099 Mpa, ensuring that the vacuum degree reaches -0.092 to -0.099 Mpa, and carrying out vacuum deoiling for 3 to 9 minutes; and taking out the deoiled codonopsis pilosula sections, spreading the deoiled codonopsis pilosula sections for cooling at the humidity of lower than 15-50%, and when the temperature of the codonopsis pilosula is reduced to 40-45 DEG C, transferring the codonopsis pilosula sections into a closed container to be stored to room temperature, so as to obtain the crisp instant codonopsis pilosula. According to the method disclosed by the invention, targeted material pretreatment is performed before low-temperature vacuum frying, so that the natural color and the special flavor of the codonopsis pilosula are maintained, and the codonopsis pilosula which is crisp, low in fat, less in nutrient loss, good in taste and ready to eat after a bag is opened can be produced.

However, these methods have greatly changed the true nature and taste of Codonopsis pilosula

In order to better retain the unique flavor and nutritional components of Codonopsis pilosula, patent CN101288476A discloses a method of vacuum low-temperature frying to process Codonopsis pilosula food, by salting Codonopsis pilosula → selecting → desalting → slicing → filling → draining → freezing → Frying → deoiling → flavoring → packaging, it needs to undergo a series of complex pre-treatment processes such as alkali soaking to remove the skin, salting, desalination, vacuum filling, freeze drying, etc. before low-temperature frying, and the sweetness of the product It is brought by maltose and needs to be seasoned. It is difficult to maintain the true flavor of Codonopsis pilosula, and the final product has a high fat content. At the same time, the stability of the product between different batches is relatively poor, so it is not suitable for large-scale industrial production.
