- WIS, water-insoluble solids; DM, dry matter; HMF, hydroxymethylfurfural, n.d., not detected
- *The lactic acid component was probably some other organic acid that had the same retention time as lactic acid.
- The values presented are the average of two separate measurements, and the standard deviations are <5%.
