(2016) Yogurt: The Product and its Manuf. Version 42-0249-00-01 The yoghurt formed was having thick and smooth consistency and was white color, set and creamy. For the sake of brevity we shall term the yogurt culture organisms as ST and LB. Corrieu, G., Spinnler, H. E., Jomier, Y. and Picque, D. (1988). Friday, January 17, 5:00pm

urt cultures, which depend on specific strain associations. Also, it altered the firmness and steadily improved the gel strength, especially at 4 and 6% levels with a noticeable comparison with the control sample. Reyes Mykee Domingo Aaron Santos Ralph Reyes LBYMATB V26B Report Title Of Activity: Yogurt Making Date Performed: October 4, 2012 I. This phenomenon induces a more rapid growth and acidifica-, tion, higher production of aroma compounds and exopolysac-, charides, and more pronounced proteolysis.

Probiotic bacteria involved in fermented milk production, other than yogurt include different lactobacilli and bifidobac-, teria. 7  Pages.

Consequently, only, manual sampling is done during the acidification process to, allow offline pH measurements, and the decision to stop the, fermentation by cooling requires a good expertise of the, process. This preview shows page 1 - 2 out of 3 pages. The reason for part one was to, conclude whether the yogurt sample met the standards set by the National Yogurt Association, that would allow the manufacturer to claim the use of “Live & Active Cultures.” These standard, are explained in the lab manual (1).   Privacy

Microorganisms have been used for preparing food products such as cheese, bread, yogurt, etc, for a long period of time without even knowing that the process involves fermentation of the starting material (Pai, 2003).

first derivatives (kinetics) of two yogurt starter cultures growing, During yogurt manufacture, controls are accomplished to, ensure repeatability of the productions and maximal levels of, quality and food safety of the products.

Similarly, the universal method of manufacturing a satisfactory yoghurt is based on the traditional process expanded (Tamime, 2006). Metabolism, Cellular respiration, Oxidative phosphorylation 536  Words |

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.

performed, at least four types of yogurt can be considered, that each step of the manufacture affects the final quality of the, yogurts and that, except for set-type yogurts, the product fla-.

In Europe (27 countries), the annual production was, around 9.3 million tons, with Germany, France, and Spain, being the three main producers covering 20%, 18%, and 9%, of the European production, respectively. Along the following centuries, the knowledge for making, homemade yogurts and fermented milks spread all over the, world. From, these findings, the identity of the unknown bacterial sample “Key Lime” was determined to be, The yogurt project consisted of two parts.

Milk of various mammals is used for making yogurt in various parts of the world. 3  Pages. BIO-218A Microbiology Lab Cindy Gainyo Bio Labs Yogurt lab summary The purpose of this assignment was to investigate the chemical process involved in lactate fermentation by making yogurt and also how organisms break down glucose without consuming oxygen. A linear decrease in the values of instability indexes and sedimentation velocities was noted in the function of inulin content increase (LUMiSizer test). sium helps to flush out some of the excess sodium out of your body.


By implementing Hazard, Analysis and Critical Control Point systems according to the, Codex, three steps are identified as critical control points for, microbiological hazards during yogurt manufacture: pasteuri-, zation of milk, refrigerated packaging, and cold storage. The increased protein content in the mix results in a custard like consistency following the fermentation period (Hui, 1992). Cynthia Alonzo, M.S. Microbiology Kit (MBK) – Lab Report Observing Bacteria and Blood familiarize with a microscope while precisely observing various bacterial shapes and their arrangements in different types of specimens of bacteria. Milk of various mammals is used for making yogurt in various parts of the world. Somatic cell counts are also verified on fresh milk.

Moreover, no significant differences were observed in the L* (lightness) and a* (-green to red) colors of the samples.

Results: TBF capsules were found to be sphere-shaped with porous surfaces, an average particle size of 1728.67 μm, an encapsulation yield of 92.85 ± 1.98% (w/w), and a glass transition temperature of 152.06 °C. Some of them are pathogenic which causes diseases but most of them are useful especially in the food industry (Lasztity, n.d.). LBYMATB V26B Report This fermentation leads to acidification and, proposes a synthetic scheme of the several char-, http://dx.doi.org/10.1016/B978-0-12-384947-2.00766-2, is stimulated by formic acid, folic acid, and CO, begins later but is prolonged even at low, -galactosidase. Discussion: The mass of yoghurt added to the milk was more than calculated, this was because there might be some yoghurt left on the weigh boat. Europe, the main producers of yogurt are China, Russia, Iran, and the United States, with 4.0, 2.5, 2.2, and 2.0 million tons, per year, respectively. Premium Among probiotic cultures, Lb. Session #1 Lab 1 Strengths The volatile compounds that have been identified in plain yogurt are summarized, with the few key aroma compounds described in detail. Fortification of yoghurt with 5 % of honey and 0.5 % of pomegranate peel powder showed a positive effect on several determinative properties such assyneresis, water-holding capacity, color, instrumental texture and sensory attributes.
