The present study aimed to analyze the physicochemical composition, bioactive compound contents and iron bioavailability (cell culture caco-2) of sweet sorghum molasses of different genotypes and compare them to sugar cane molasses. Sorghum molasses presented proteins (0.28–2.90%), lipids (0.07–0.53%), total dietary fiber (0.00–2.85%), carbohydrates (90.16–93 0.29%), pH (4.67–4.95), acidity (0.3–0.45) and BRIX (38.2–58.5°). The sorghum molasses contained high ash concentration (3.30–6.86%) and calcium (397–966 mg), compared to sugar cane (1.98% and 70 mg). Sorghum molasses presented higher levels of total phenolic compounds (19.3–48.4 mg GAE/g) compared to sugar cane (8.8 mg GAE/g). Ferritin concentration was higher in two sorghum molasses (6.3–6.8 ng/mg), compared to sugar cane (4.3 ng/mg). Thus, sorghum molasses proved to be a promising source of minerals and bioactive compounds and an excellent food to be used in human nutrition. [Display omitted] •Ten different genotypes of sweet sorghum molasses were analyzed.•All sorghum molasses contained high ash concentration and calcium.•CMSXS 5039 and CMSXS 5022 molasses have higher iron content.•Sorghum molasses showed good in vitro iron bioavailability.•Sorghum molasses is a natural product with good physical property.
