Expanding the range of rapid analysis approaches to semi-polar volatiles and non-volatile precursors in grapes
Targeted measurements of volatiles or volatile precursors in grapes are useful for grape and wine quality evaluation, but these analyses are typically slow, and routine fee-for-service analyses are typically prohibitively expensive. Our group has previously demonstrated that sorbent sheets (SPMESH) could be used for rapid extraction of non-polar odorants from sample headspace. In the past year, we evaluated two novel extensions of SPMESH to make it more appropriate for analysis of semi-polar, lower volatility and
