Problems solved by technology

[0004] At present, the commonly used methods for the detection of chromium in food include atomic absorption graphite furnace method and oscillographic polarography. If the current general analysis method is used, there are problems such as complicated operation, large reagent consumption, serious interference, poor accuracy, and long analysis cycle.
Sample pretreatment before detection is also important. Traditional dry method, wet method and other sample pretreatment methods have disadvantages such as complicated process, long time, large amount of reagents, and serious interference to detection.

Embodiment 1

[0033] Embodiment one, the detection of 27 edible gelatin samples.

[0034]The 27 edible gelatin samples were all taken from edible gelatin sales stalls and enterprises, and the samples were tested separately. After being pulverized evenly, pass through a 800-mesh sieve, weigh 2.5 g and place it in a polytetrafluoroethylene tank, add 4 mL of nitric acid and soak for 24 hours. Then add 2 mL of 30% hydrogen peroxide, cover the inner cover, tighten the stainless steel jacket, put it into the microwave digestion instrument, and set the parameters of the microwave digestion instrument for digestion. Digestion includes four stages: the first stage set the pressure 0.5MPa, power 600W, run for 5 minutes; the second stage set the pressure 1.0MPa, power 600W, run for 3 minutes; the third stage set the pressure 1.5MPa, power 600W, run for 3 minutes ; In the fourth stage, set the pressure to 1.8MPa, power to 800W, and run for 5 minutes. After digestion, cool to room temperature, filter ...

Abstract

The invention discloses a method for measuring chromium content in edible gelatin. After the edible gelatin sample is digested by microwaves, it is detected by an inductively coupled plasma atomic emission spectrometer, thereby obtaining the chromium content in the edible gelatin sample. Compared with the prior art, the present invention adopts the combination of inductively coupled plasma atomic emission spectrometry and microwave digestion, which has the characteristics of high sensitivity, good precision, wide linear range and fast analysis speed, and provides a new method for the detection of heavy metals in candies. A convenient, fast, accurate and reasonable detection method can meet the needs of enterprises and inspection and testing units.

Description

technical field [0001] The invention relates to the technical field of inspection and detection, in particular to a method for determining the chromium content in edible gelatin. Background technique [0002] In recent years, various problematic foods have been frequently exposed in the news, ranging from "melamine", "gutter oil", "clenbuterol", "plasticizers" to "leather capsules" and so on. Food is the first priority for the people, food safety is the priority, and safety is quality-oriented. With the development of my country's economy, people's living standards continue to improve, and more and more attention is paid to food safety and quality issues. [0003] As a natural nutritional thickener, emulsifier and softener rich in amino acids and free of cholesterol, edible gelatin is widely used in candy, jelly, jelly, cheese, yogurt and other foods. In recent years, with the improvement of the public's demand for food taste, the demand for gelatin has continued to increas...
