This study was conducted on frozen and stewed peanuts using UV-Vis spectrophotometry method. The study was conducted by reading absorbance using a wavelength of 616 nm. Measurements were made by adding buffer ammonia, blue bromtimole and PVA. Vitamin B1 levels were performed with a linear equation followed by statistical test of SPSS 21. Based on the result of determination of vitamin B1 level on raw cowpea by using UVVis spectrophotometry that is steamed cauliflower 0,00919% mg/ 100g, fried 0,00804% mg/100g. The results of statistical tests using two way anova test can be known to be fried and steamed stumps have different levels. .
