The Effect of Pineapple Addition at Different Rates to Sheep Yoghurt on Antioxidant Activity, 5-Hydroxymethylfurfural (HMF) Content, and ABT-2 Probiotic Culture Growth

Abstract

In the present study, the effect of adding pineapple at different rates to sheep yoghurt produced using ABT-2 culture on antioxidant activity, total phenolic compound amount, and 5-hydroxymethylfurfural (HMF) content was investigated. In addition, the effect of pineapple addition at different rates and storage periods on physicochemical analyses (total solids, fat, protein, ash, viscosity, pH, and titratable acidity values), growth of ABT-2 probiotic cultures (Streptococcus salivarius subsp. thermophilus, Bifidobacterium sp., Lactobacillus acidophilus), and sensory evaluation in the experimental sheep yoghurt samples were examined. It was determined that the addition of pineapple to sheep yoghurt samples produced with ABT-2 probiotic culture had a very significant effect (p
