“…Nixtamalisation or alkaline-cooking of corn is a Mexican ancient process known as the basis for the production of a diversity of corn products, particularly corn tortillas that are an important source of carbohydrates and calcium for the Mexican population (Upton et al, 2015). According to the report of Centro de Estudios para el Desarrollo Rural Sustentable y la Soberan ıa Alimentaria (CEDRSSA (Centro de estudios para el desarrollo rural sustentable y la soberan ıa alimentaria), 2014), the annual per capita estimate of tortilla consumption in rural and urban areas in M exico is around 79.5 and 56.7 kg, respectively.…”

Summary Removing solid lime particles (SLP) may help to prevent polluting characteristics of corn cooking wastewater (nejayote). The objective of this study was to evaluate the polluting characteristics of nejayote and characteristics of nixtamal, masa and tortilla using SLP‐free solutions (SLPF) for the nixtamalisation process. Two SLPF treatments: calcium hydroxide (CHYDROX) and calcium oxide (COXIDE) were compared against traditional nixtamalisation (TRADNIX). Polluting characteristics including pH, settleable solids, total hardness, alkalinity and chemical oxygen demand (COD) reduced by 29.5% and 24.3%, 61.9% and 63.3%, 46.3% and 54.7%, 43.3% and 55.1%, 41.1% and 67.7% in CHYDROX and COXIDE, respectively, compared to TRADNIX. Masas and tortillas from SLPF treatments were whiter than those from TRADNIX. Moisture in SLPF tortillas was lower by 4.3–6.3% compared to TRADNIX. Tortillas from SLPF treatments had higher maximum tensile strength (0.04–0.08 N mm−2) than TRADNIX. Removing SLP is a viable strategy for preventing pollution from the nixtamalisation process.
