Abstract

 This study evaluated the vitamin and phytochemical profile of six tomato brands marketed in Samaru, Zaria, and examined their potential implications for animal feed, health, and leather industry applications. Fresh tomatoes contained the highest levels of Vitamin A (22.98 mg/100g) and Vitamin D (32.10 mg/100g), while processed brands showed variable retention. Notably, Brand C recorded significantly higher Vitamin C (81.01 mg/100g) and Vitamin E (80.16 mg/100g), suggesting concentration or fortification during processing. Phytochemical screening revealed that saponins, alkaloids, and flavonoids were consistently present across most samples, while tannins, glycosides, phenols, and quinones were inconsistently distributed. Quinones were detected only in Brand D, while phytate and oxalate appeared variably, indicating potential anti-nutritional considerations. Among the brands, Brand C demonstrated the most promising nutritional profile, combining high Vitamin C and E with a broad range of phytochemicals, making it a strong candidate for use as a functional feed supplement. Brands A and B also showed potential, particularly for supporting epithelial health and immunity. The findings highlight that tomatoes marketed in Samaru, Zaria, are rich sources of vitamins and bioactive compounds with significant potential to enhance animal health, improve hide and skin quality, and add value to the leather industry.
