Abstract
Free and total pantothenic acid (FPA and TPA) in spinach and broccoli were determined at various processing stages. Steam-blanching resulted in greater TPA retention thatn water-blanching. Spinach retained 36% TPA activity after water-blanching compared with 87% retention after steam-blanching. Similar trends were noted for TPA loss during blanching of broccoli. Canning of water-blanched spinach resulter in a further significant loss (α= 0.05) of TPA. TPA was stable in canned spinach and frozen spinach. Frozen storage of broccoli for 60 days at – 32.2°C resulted in loss of TPA. No further loss was observed between 60 and 160 days of frozen storage. FPA was lost to a greater extent than TPA during water-blanching of both vegetables.
