Difference and preference sensory tests were conducted to select the most preferred formulation containing an addition of 1–3% hydrolyzed collagen. The results indicate that the formulation with the addition of 2.5% hydrolyzed collagen was significantly preferred. Drinks at pH 3.96–4.04 were pasteurized at 95 °C until reaching P value necessary for 3D decimal reduction of Alicyclobacillus acidoterrestris.
