HYDROXYMETHYLFURFURAL IN CANNED FRUIT

A standard method for the quantitative determination of 5-hydroxymethylfurfural in canned fruit products using reversed-phase high-performance liquid chromatography and spectrophotometric detection in the ultraviolet region of the spectrum at a wavelength of 284 nm has been verified. The results of calculations of acceptance criteria during verification (repeatability and intermediate precision indices) showed that the considered method for determining the concentration of HMF in canned fruit described in GOST 31644-2012 is reproducible in a chromatographic research laboratory, and the obtained results can be considered reliable. It was shown that from 17.02 to 23.56 mg/dm3 of HMF were detected in canned apples (puree and jam), which indicates the advisability of industrial control of the conditions of processing and storage of such products.
