Embodiment 1

[0008] 70g of bird’s nest (with a nitrite content of 5843mg / kg) was placed in an ultrasonic cleaner, using water as the medium, ultrasonically treated at room temperature for 10 minutes, ultrasonic power 50W, ultrasonic frequency 20kHz, washed 3 times, placed in Midea brand FY07MS-CYA fruits and vegetables In the sterilizer, treat with ozone for 60 minutes, take it out, and dry it in the air. The shape and color of the bird’s nest will not change. According to the second method spectrophotometry of the GB / T 5009.33-2008 standard, the content of nitrite in it is 26mg / kg.

Embodiment 2

[0010] 70g bird's nest (nitrite content is 3299mg / kg) is placed in an ultrasonic cleaner, using water as the medium, ultrasonically treated at room temperature for 30min, ultrasonic power is 2500W, ultrasonic frequency is 50kHz, washed 3 times with water, placed in Midea brand FY07MS-CYA fruit and vegetable In the disinfection machine, ozone treatment for 120min, take it out, dry it, the shape and color of the bird’s nest cup remain unchanged, and the content of nitrite in it is 18mg / kg according to the second spectrophotometric method of the GB / T 5009.33-2008 standard.

Abstract

The invention relates to a method for removing nitrites in cubilose, belonging to the technical field of standard-exceeding components in food. The nitrites in the cubilose are removed by combining an ultrasonic technology and an ozone technology, therefore, the content of the nitrites in the cubilose is reduced to be below 30mg / kg, and the cup type and the color of the cubilose can be kept unchangeable. The method comprises the following steps: putting the cubilose in water for ultrasonic treatment for 10-30min with ultrasonic power of 50-2500W and ultrasonic frequency of 20-50 kHz; washing with water for three times, placing into an ozone generator for ozone treatment for 6-120 min by using the water as a medium; and naturally drying. The invention can keep the cup type and the color of the cubilose unchangeable; no chemicals are added, the product after the ozone is oxidized is water without harmful substances so that the cubilose and the environment can not be polluted; the method is an environmental-friendly treatment technology; the ozone has the sterilizing function, and the treated cubilose is not easy to mould; and the invention has simple process, little equipment input and cost saving, and is suitable for the industrialized treatment.

Description

technical field [0001] The invention relates to a combined method for removing nitrite in bird's nest, and belongs to the technical field of removing excess ingredients in food. Background technique [0002] The bird's nest was first recorded in "Materia Medica Fengyuan". It is a nest built by the saliva secreted by several birds of the swift family Apodidae (Apodidae) and the genus Collocalia mixed with their down feathers and condensed on the cliffs. It is produced in Indonesia. , Malaysia, Thailand, Vietnam, Myanmar and other places, as well as my country's Fujian, Guangdong, and Hainan coastal areas. Its nature and flavor are sweet and flat, and it returns to the heart, lung, and kidney meridian. In order to spread and use, it has the reputation of "Oriental Treasures", and it is a high-grade health product suitable for medicine and diet (Hu Yani, Li Feng, Kang Tinguo. Research progress of bird's nest. Chinese Journal of Traditional Chinese Medicine, 2003, 28(11): 1003-1...
