Acidification activity of, starter cultures is also assessed, mostly by using the Cinac, system that allows determining various quantitative kinetic, descriptors such as the absolute value of the maximum acidi-, sary to reach Vm. Since the, 1950s, the production of yogurt has grown significantly thanks, to the intervention of several powerful agrofood groups setting, up international activities. In addition, olized into diacetyl or acetoin through the action of, acetolactate decarboxylase that allows regulating leucine and, Acidification of milk leads to coagulation as a result of desta-, bilization of the casein micelles. Similarly, the universal method of manufacturing a satisfactory yoghurt is based on the traditional process expanded (Tamime, 2006). addition, packaging is also related to physical hazards. The mechanical constraints exerted on stirred. In conclusion, fortification of yoghurt with 5 % of honey and 0.5 % pomegranate peel powder offered a novel yoghurt with acceptable sensory characteristics, good physicochemical and textural properties, and interesting antioxidant activity without inhibiting the development of lactic acid bacteria. In this method, interfering laser beams heat the liquid surface and generate a laser-induced capillary wave (LiCW) caused by spatially sinusoidal temperature distribution. March 23, 2013 Yogurt gels are a type of soft solid, and these networks are relatively dynamic systems that are prone to structural rearrangements. activity of a symbiotic blend of Streptoccoccus thermophilus and Lactobacillus delbruekii subsp.Bulgaris (LB) cultures. in the northeast of Africa, in the Middle East, in Central Asia, and later in Balkan countries, offering a large variety of, ‘fermented milks.’ Originally, yogurt resulted from a spontane-, ous, accidental lactic acid fermentation leading to the acidifi-, cation and coagulation of milk, thus resulting in an efficient, way to preserve this raw material otherwise vulnerable to spoil-, age. The pH values showed a slight delay in the fermentation process at 4 and 6% concentrations and slightly increased the pH, as the concentration increased. Yogurt quality requires controls of the raw materials, during, the course of the manufacturing process and on the final, Microbiological controls are carried out on raw materials, in, particular fresh milk, powder milk, fruits, sweeteners, and, starters. They encompass (1) sensors that essentially measure, physical parameters such as temperature, pressure, level, and. Premium Introduction Last October 4, the group performed an activity that involved making our own yogurt.The group prepared the materials and followed the procedures to make the said yogurt. agents (sugar or other sweeteners for low-calorie products), flavoring agents (fruit aromas or vanilla) or fruits (small pieces, enriched with sugar or jam), stabilizers (pectin, starch, or, gelatin), or emulsifiers; and (3) the technology employed for, the manufacture, which may vary depending on the operations, during milk pretreatment (fat and nonfat solid standardiza-, tion, homogenization, or heat treatment) or yogurt post-, treatment (stirring, concentration, mixing, cooling, drying, or, Even if yogurt is the most consumed within the wider, family of fermented milks, many probiotic fermented milks. The health benefits, the technology of production of fermented milks and the kinetics of lactic acid fermentation in dairy products are reviewed here. tains many different useful vitamins including Vitamin B12, potassium, riboflavin, zinc, and vitamin B5. Main Types of Yogurts and Fermented Milks, Yogurt diversification is reflected by various textures (set-type, or firm, stirred, drinking, frozen, concentrated, or powder, yogurts), numerous flavors (natural, sweetened, flavored, or, with added pieces of fruits or honey), and diverse shelf life and, nutritional (fat content and residual lactose content) proper-, Classification of fermented milks is also based on their, potential health properties.
