Resumo: Abstract The present study conducted to assess nutritional, safety parameters (aflatoxin M1/AFM1 and heavy metals; copper, cadmium and zinc) and fatty-acid composition of tea-whiteners (TWs). Accordingly, TW’s samples composition (moisture, ash, protein, fat and nitrogen free extract) determined using AOAC methods, minerals including Na, K and Ca heavy metals including Cu, Cd and Zn determined via atomic absorption spectrophotometer. The AFM1 measured using thin layer chromatography (TLC) whereas, fatty acids and trans-fat contents were determined using gas chromatography. ANOVA and independent sample t test applied to assess the significant difference. Results indicated that protein and fat contents (%) of liquid TWs were 2.7-5.4 and 4.28-6.48, respectively. Powdered TWs protein and fat (%) were 13.4-17, and 23.06-29.03, respectively. AFM1 was not found in any TW. Cu/Cd and Zn levels (ppm) of liquid TWs were 0.296-2.075, ND-1.206 and 0.009-0.026 respectively. For powdered TWs the readings (ppm) were 0.515-0.632, 0.003-0.005 and 0.010-0.013 respectively. Trans-fats (%) in liquid TWs were 2.90-7.51 and in powdered TWs were 1.29-1.83. In nutshell, TWs had traces of trans fats ranged 1.29-7.51% whereas, liquid TWs contain more trans-fats than powdered TWs. Major fatty acids among liquid and powdered TWs were palmitic acid, heptadecanoic acid, stearic acid and oleic acid.
