4-Hexylresorcinol is a white, yellow-white needle-like crystal, which turns brown and also pink when subjected to light and air. It has a weak odor as well as a solid astringent preference, and also can cause numbness to the tongue. In medicine, 4-hexylresorcinol has a lengthy background of application as a coughing sedative. In the field of food, 4-hexylresorcinol, as a new kind of antioxidant, was first utilized in the conservation of shrimp, and also later on in the conservation of veggies and fruits.
The speculative outcomes show that 4-hexylresorcinol has a great fresh-keeping effect, which can prevent shrimps from turning black, hinder the browning of mushrooms, fresh-cut pears, as well as potatoes, prolong the storage space duration of fresh-cut apples, and prevent microbial development. development, play an antibacterial duty. Yet whatever sort of additive it is, it can not be included at will, otherwise it will cause harm to the body. Therefore, quantitative discovery of 4-hexylresorcinol deposits in food is essential to ensure food security.
In order to meet the current food testing needs, the National Health And Wellness Commission as well as the State Administration for Market Policy issued GB 5009.280-2020 “National Food Safety And Security Criterion – Decision of 4-hexylresorcinol Deposits in Food”.
This conventional specifies the technique for the determination of 4-hexylresorcinol residues in shrimp as well as crabs, as well as is applicable to the decision of 4-hexylresorcinol deposits in shrimps and also crabs. The conventional states that when shrimp and crab evaluate 2.00 g, the detection restriction is 0.0200 mg/kg, as well as the metrology limitation is 0.0500 mg/kg.
Program according to the requirement, when utilizing this criterion to determine the recurring quantity of 4-hexylresorcinol in shrimp and crab, require to utilize fluid chromatograph, equilibrium, rotating evaporator, vortex mixer, ultrasonic generator, centrifuge, consistent tools, and so on.
GB 5009.280-2020 “National Food Security Standard Resolution of 4-hexylresorcinol deposits in food” will certainly be executed on March 11, 2021, and will change SN/T3641 -2013 “4-hexylresorcinol in exported aquatic items Resorcinol deposit detection technique”. Compared with SN/T3641 -2013 “Discovery approach for 4-hexylresorcinol deposits in exported aquatic products”, the changes in the new standard are mainly shown in two elements: 1. The name of the requirement is changed to “National Food Safety Standard 4-Hexyl Resorcinol in Food – Determination of recurring amount of hexylresorcinol”; 2. Modified the operation of the pretreatment part.
Every revision of the requirement is the enhancement of the basic system. It is thought that the application of the new standard will certainly further improve the food screening criteria and offer more assurances for my country’s food safety and security.
