Ohaus assists in the determination of vitamin C content in meat products

Amy's little fairy knows that your diet is not only related to your overall health, but more importantly, your diet will also affect your skin health. In addition to eating foods rich in vitamins and minerals, ingesting fresh fruits and vegetables can help your body get antioxidants, help promote skin health and protect the skin from the sun. Because fresh fruits and vegetables are rich in vitamin C,
Vitamin C has always been a star in the vitamin family, with whitening and enhanced immunity. Since the human body cannot make vitamin C, and vitamin c can only stay for 4 hours in the human body, it is supplemented at least twice a day. At the same time, because a cigarette can destroy 25mg of vitamin C, people who smoke for a long time need to take vitamin C.
In addition to the richness of vitamin C in fresh fruits and vegetables, little fairies know that meat products also contain vitamin C. Is it good news for you who love food? Today we will take a look, Ohaus assists in the determination of vitamin C content in meat products.

1 Scope
This part of GB/T 9695 specifies the method for determining the vitamin C content of meat products.
This section applies to the determination of vitamin C content in meat products
2 Principle The vitamin C in the sample is extracted with metaphosphoric acid, oxidized to dehydrogenated vitamin C by 2,6-dichloroindophenol, and reacted with o-phenylenediamine to form a quinoxaline derivative having violet-blue fluorescence. The fluorescence intensity was measured at an excitation wavelength of 350 nm and an emission wavelength of 430 nm, and quantified by a standard curve method.
Dehydrogenated vitamin C and boric acid form a complex without reacting with o-phenylenediamine, thereby eliminating interference from fluorescent impurities in the sample.
