Managing the sugar/acid ratio in pome fruits
Pome fruit flavor and taste are related to the level of soluble solids in the fruit, which are mainly sugars. Total Soluble Solids (TSS) is therefore of extreme importance to measure the quality of pome fruit. Referred to as oBrix, TSS is assessed by refractometry or near-infrared spectroscopy and can be used to check fruit maturity and ripeness, important to determine harvest timing. A balanced crop nutrition can influence TSS content of fruit.
