Sensory evaluation and instrumental methods were applied to the
evaluation of strawberry juice concentrate (68°Brix) stored at
20°C which had been produced both commercially (C-SJC) and in a
pilot plant (SJC). Sensory evaluation included taste and aroma
ratings by intensity scaling and time-intensity of taste, and visual
colorimetry by matching...
Response Surface Methodology (RSM) was used to study the effect
of two variables, sugar level (12-16 °Brix) and acid level (0.3-0.7
% T.A.) on sensory qualities and desirability of blackberry juice
drinks. Three blackberry juice levels (10%, 15%, and 20%) were used
to study the influence of juice flavor on...
Acidulants are an important functional ingredient group in the food industry, providing sourness, lowering pH, ensuring safe processing, and extending shelf life. Hence, understanding the effect of acids on sensory characteristics of foods is critical. Of the many topics dealing with acidulants, sourness is a topic where considerable research has...
Heat treated orange juice, both pasteurized and concentrate, are being increasingly
consumed in the U.S. Orange juice is primarily heat treated to increase its shelf life, by
curbing the growth of microorganisms; and to inactivate pectin methylesterase, which
demethylates pectin and leads to cloud loss in the juice. However, because...
