Embodiment Construction

[0040] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0041] Preparation of a bitter gourd extract

[0042] Wash the bitter gourd, dry it with filter paper, take an appropriate amount of bitter gourd and carefully grind it into a uniform slurry at room temperature, accurately weigh 2.50g, transfer it to a 50mL volumetric flask with deionized water, make it to volume, heat it in a water bath for 10min, and filter it with nylon cloth after cooling , Suction filter until clear, and store in a dry container at 4°C. 1mL of crude extract is equivalent to 0.05g of the raw material Piccaria chinensis. The preheating temperature gradient of the water extract of Sophora japonica is: normal temperature (18°C), 30, 40, 55, 70, 80, 90, 98 (°C). After cooling to room temperature, react with sodium nitrite. Other conditions: dosage 10mL, reaction time 10min.

Abstract

The invention relates to a nitrite scavenger and a preparation method thereof, in particular to an application of Chinese onion or extract thereof in preparing a nitrite scavenger, belonging to the field of food. The invention also relates to a preparation method of the Chinese onion or the extract thereof, which comprises the steps of pulping and water extraction/ethanol extraction. The scavenger can be used for preparing a cleaning agent for fruit and vegetable, health food and additive of pickled vegetable or pickled food. The scavenger can not be damaged and failed due to the influence of high temperature, and has good scavenging effect under the condition that the pH is 2.0-10.0. The scavenger is a pure natural extracting solution without any toxic and side effects, wherein the scavenging effect of 5.5g of Chinese onion or an equal amount of extract is equivalent to that of 100mg of vitamin C. The preparation method has simple operation and low production cost. The cleaning agent for fruit and vegetable, health food or food additive prepared from the scavenger have no toxic or side effect on the human body, and can realize an effect of scavenging the nitrite quickly (in 3 minutes).

Description

technical field [0001] The invention relates to the field of food, in particular to a nitrite scavenger and its preparation method and application. Background technique [0002] Nitrite exists widely in the natural environment. In food, nitrite exists in almost all pickled products, meat products, pickles and harvested vegetables; nitrite is also often used as a food preservative; , fish, meat products, egg milk intake and enter the human body. The average content of nitrite in vegetables is about 4 mg / kg, meat is about 3 mg / kg, eggs are about 5 mg / kg, the average content of soybean powder can reach 10 mg / kg, and the average content in pickles is also Above 7 mg / kg. According to reports, 81.2% of the nitrate ingested by the human body comes from vegetables. Nitrite in food can cause methemoglobin poisoning in humans, and can also cause teratogenicity and goiter. More importantly, nitrite is a precursor of strong carcinogen nitrosamines. In nature, nitrite is easily com...
