Dc. Slaughter et al., NONDESTRUCTIVE DETERMINATION OF SOLUBLE SOLIDS IN TOMATOES USING NEAR-INFRARED SPECTROSCOPY, Journal of food science, 61(4), 1996, pp. 695-697
A nondestructive optical method for determining the soluble solids con
tent of fresh whole tomatoes was investigated. The method, based upon
near infrared spectrophotometric techniques, could predict the soluble
solids content of tomatoes (r = 0.92, SEC = 0.27 degrees Brix). Tomat
oes from more than 30 popular fresh market cultivars at stages of matu
rity from mature green to ripe red fruit were studied.
