Toward “clean label” processed meat using starter culture and beetroot powder: A case‐study in restructured cooked ham

Abstract

This study evaluated the effects of the combination of beet powder, starter culture, and sodium erythorbate as a curing agent on the chemical and microbiological characteristics of restructured cooked ham during cold storage. Five treatments were developed: the positive control group (COP) with the addition of nitrite and sodium erythorbate, negative control treatment (CON) with the addition of sodium erythorbate; ham added with beet powder (AP), ham added with beet powder and starter culture (APC), ham added with beet powder, starter culture, and sodium erythorbate (APCE). The ham's curing properties and oxidative stability were analyzed for 30 days under refrigeration. The APCE treatment showed better conversion of nitrate to nitrite at time 0 (46.6 mg/kg). The COP sample showed higher residual nitrite content at time 0 (73.1 mg/kg) and nitrosohemochrome pigment (35.67 ppm). Combining beet powder with the commercial starter culture and sodium erythorbate in the formulation of restructured cooked hams positively affected the control of lipid and protein oxidation, making it an alternative to commercial sodium nitrite.Practical ApplicationBeetroot and arugula powders are added to the restructured cooked ham to prepare a clean‐label meat product without sodium nitrite. The effects of starter culture and sodium erythorbate are also evaluated. .
