Embodiment 1

[0027] The invention discloses a selenium-enriched crispy instant lotus seed. The selenium-enriched crispy instant lotus seed is an instant leisure lotus seed food with a selenium content of 0.10 mg / kg-10 mg / kg, a fluffy structure and a crisp taste.

[0028] The manufacturing process of the described selenium-enriched crisp instant lotus seeds mainly comprises the following steps:

[0029] (1) Selection: choose ordinary dried lotus seeds that have been peeled and cored, free from mildew, damage, selenium-free or low-selenium content as raw materials;

[0030] (2) Soaking: Soak the dried lotus seeds selected in step (1) in selenium-enriched water with a selenium content of 1-20 mg / kg for 2-12 hours. The weight of the selenium-enriched water is 1% of the weight of the dried lotus seeds. ~10 times, then heated and boiled, and the boiling time was maintained for 10-60 minutes to obtain cooked lotus seeds;

[0031] (3) Low-temperature freezing: pick up the cooked lotus seeds obtai...

Abstract

The invention relates to selenium-rich crisp instant lotus seeds and a production process thereof, wherein the selenium-rich crisp instant lotus seeds are instant snack lotus seed food which contains 0.10mg / kg-10mg / kg of selenium elements, are fluffy in structure and crisp in mouthfeel; the production process of the selenium-rich crisp instant lotus seeds is a process which takes selenium-rich or low-selenium and dried natural lotus seeds as materials to carry out selenium increasing and crisping processing, and comprises the steps of selenium-rich water digesting, low-temperature freezing, selenium-rich oil vacuum frying, centrifugal oil-removing, mixing and the like. According to the invention, technical problems that the common natural dry lotus seeds are dry, hard and difficult to chew due to compact structures, and functional needs of agricultural product food are not satisfied due to no selenium or low selenium content are synchronously solved; moreover, the production process is simple and feasible, low in cost and has wide application prospect.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a selenium-enriched crispy instant lotus seed and a production process thereof. technical background [0002] Lotus seeds are a large local characteristic agricultural product in Hunan, Jiangxi, Fujian, Zhejiang and other regions of our country. Among them, the Xianglian produced in Hunan is the most distinctive. It has always been a treasure of tribute to the court, so it is also called "Gonglian", known as " China's first lotus seed". Because of its compact structure, difficult to chew, and unpleasant instant taste, lotus seeds are rarely used as instant snacks; at the same time, lotus seeds are mostly produced in rivers and lakes. In areas where rivers and lakes are polluted by heavy metals, lotus seeds are inevitably free from heavy metals. Pollution. [0003] According to literature reports, selenium is an essential functional trace element for the human body. It has the fun...
