Abstract

A series of batch fermentations of cheese whey using Lactobacillus helveticus 8652 were monitored both off-line and on-line by FT-IR using a CIRCLE cell (Spectra-Tech, Warrington). The levels of substrate (lactose) and product (lactic acid) were continuously measured over a period of 48 h. Measurements were made on a Perkin Elmer 1760 FT-IR spectrometer using the QUANT software. Fifteen calibration solutions of lactose and lactic acid were used and the method tested with validation solutions of known composition. Mean errors of 1.1% and 0.9% w/v were calculated for lactose and lactic acid respectively.
