Poly parameter food safety quick analytic instrument

Abstract

The rapid analysis instrument includes body case, fixed ring of color comparison pool, multiple push button keys, liquid crystal screen, RS232 interface, as well as color comparison pool, color comparison bottle, monochromatic source, photoelectric detector, and microproceesor etc. The instrument also includes printer embedded in body case, and heater for sample. The disclosed instrument is capable of measuring content of following objects in food: cadmium, chrome, nickel, rare earth, nitrite, formaldehyde, amylase, toxicity of pesticide residue, vitamin E, trimethylamine etc.

Description

technical field [0001] The invention relates to a simple, sensitive and rapid analysis instrument, in particular to a multi-parameter food safety rapid analysis instrument for rapidly and quantitatively detecting the content of toxic and harmful substances in food on site. Background technique [0002] With the continuous deepening and development of economic globalization, food safety issues have attracted more and more attention from governments, international organizations, industry organizations, industry experts and even ordinary people. Ensuring food safety has become the basis for ensuring survival and protecting human life and health, and the basis for improving economic operation and human life quality. At the same time, the rapid detection technology to ensure food safety has also been highly valued by relevant departments, and many rapid detection methods have also been included in the standard methods of various countries. There are many kinds of harmful substan...

Problems solved by technology

This is because cottonseed contains a large amount of gossypol, gossypol and other toxic substances, and the unrefined crude cottonseed oil cannot completely remove gossypol, and free gossypol is a kind of cytotoxin and vascular neurotoxin, which can Cause damage to the stomach and kidneys of the human body, and may also cause male and female infertility

Therefore, crude cottonseed oil should never be eaten

[0021] Sodium cyclamate, also known as sodium cyclamate, is a new water-soluble sweetener whose sweetness is 30-40 times that of sucrose [4]. Due to its low price and high sweetness, it is often used as a A substitute for sucrose, but because it has no nutritional value, if consumers often eat drinks or other foods with excessive cyclamate content, it will cause harm to the liver and nervous system of the human body, especially for the elderly with weak metabolism and detoxification ability more obvious

[0022] The harmful substances in the above food have seriously affected people's normal life, and it is very necessary to be able to quickly detect the content of these harmful substances on the spot. The existing detection methods are generally limited to laboratory operations and cannot be tested on-site; , and it is only limited to the detection of a single parameter. At present, there is no method and analytical instrument that can combine multiple parameters together for on-site rapid detection.
