METHOD FOR DETERMINING α-FARNESENE AND ITS OXIDATION PRODUCTS IN A STORAGE ATMOSPHERE FOR EVALUATING SUSCEPTIBILITY OF FRUITS TO SUNBURN Russian patent published in 2019 - IPC G01N21/31 G01N33/52 A01G13/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and can be used for evaluation of susceptibility of fruit batches to sunburn in horticultural enterprises engaged in storage of apples. Determination method α-farnesene and its oxidation products in a storage atmosphere to assess susceptibility of apple fruits to sunburn is that sorbent tapes are prepared by impregnating paper strips with vaseline oil, placed in storage chambers without contact with fruits, and content α-farnesene and its oxidation products are determined by spectrophotometric method in sorbent tapes, which indirectly reflects their content in the storage atmosphere.

EFFECT: disclosed method of determining content α-farnesene and its oxidation products enables to evaluate the sunbath susceptibility of the whole lot of fruits (50–200 t and more) placed in the chamber, wherein the method is characterized by high efficiency, high accuracy, does not require expensive equipment and high skill of the operator, can be used for mass analysis.
