Citation abstract

The utility of plasma-treated winter mushroom powder (PWMP) as an alternative to synthetic nitrite and phosphate in ground ham was evaluated. Treatment of atmospheric non-thermal plasma generated nitrite in winter mushroom homogenate, and PWMP contained 4.87 g/kg of nitrite. Canned ground ham samples without nitrite and phosphate (NC), with sodium nitrite and sodium pyrophosphate (PC), and with PWMP (PWM) were manufactured, sterilized (F 0 > 4), and stored under accelerated conditions (40 °C) for 30 days. The nitrosyl-hemochrome content and color of PWM were similar to those of PC, without differences in the thiobarbituric acid reactive substances (TBARS) value. The proportion of jelly and melted fat exuded from ground hams in PWM exceeded that in PC but was lower than that in NC (P <.05). Therefore, PWMP can successfully replace synthetic nitrite, but it is an insufficient substitute for phosphate in ground ham.
