The physicochemical and organoleptic characteristics of yoghurt samples made from dried and fresh African breadfruit seeds were investigated. After cleaning, 5 kg of breadfruit seeds were parboiled for 30 minutes at 80°C to remove the hulls. The seeds were dehulled and weighed 2.5 kg apiece. One batch was immediately ground into flour, and the other was allowed to dry in the sun for 5 days before processing. Breadfruit milk extract was extracted from every batch by filtering the slurry through a 0.04 mm sieve. After being continuously stirred for 30 minutes, the milk was allowed to cool to room temperature. A commercial yoghurt starter culture (a 50:50 mixture of Streptococcus thermophilus and Lactobacillus bulgaricus) was mixed with African breadfruit milk to produce both fresh and dried African breadfruit yoghurt. The milk and yogurt samples were evaluated. The mean data were statistically analyzed using SPSS software version 23 and separated using One-Way ANOVA’s Least Significant Difference at (p ≤ 0.05) method. The physicochemical properties of the milk samples showed that the pH was 5.95 and 5.88; total titratable acidities were 0.34% and 0.31%; specific gravities were 1.013 and 1.011; viscosities were 244 cP and 352 cP of fresh and dried African breadfruit seeds respectively. The physicochemical properties of yoghurt samples showed that the pH were 5.24, 5.01, 4.71; total titratable acidities were 0.85%, 0.68%, 0.81%; specific gravities were 1.03, 1.04, 1.07 and viscosities were 417 cP, 473 cP, 495 cP of fresh and dried African breadfruit and cow milk respectively. The organoleptic properties show that the panelists preferred the commercial yoghurt to the yoghurt samples from African breadfruit seeds. Yoghurt samples from African breadfruit seeds can compete favourably in the market if the standards are maintained during and after processing.
