yoghurt involved the pretreatment of milk follow by the homogenization‚ heat treatment‚ cooling to incubation temperature‚ inoculation with starter‚ fermentation ‚ cooling‚ post fermentation treatment‚ chilling and lastly packaging for commercial yogurt production. In this experiment‚ the making of yoghurt followed the batch process. The 1000ml of UHT milk is mixed with some milk powder to increase the content of milk solid non fat in the milk in order to improve the texture with the help of protein

Abstract In food industry such as the production of cheese‚ bacteria takes a significant role on the wide variety of cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After

Observing Bacteria Kelli Jo Simco Microbiology Due: 2/8/13 Abstract: Microscopes are fragile instruments that must be handle with extreme caution as they can produce high quality results when observing the smallest specimens on earth. A microscope must be properly cleaned before use and storage. The different objectives allow for a range of observations. At the highest objectives‚ the resolution can easily be lost which is why the oil immersion lens is used to minimize refraction. While

Yogurt and Labneh Cheese Yogurt is made by adding cultures called lactic bacteria to fresh milk. The bacteria are added to heated and pasteurized milk and incubate to maximize the bacterial activity. The bacteria then covert the lactose to lactic acid‚ which thickens the milk and makes it tangy. Milks natural Ph is 6.5 but when it rises to 5.5 the capping casin that keeps the micelles separate in milk no longer repel and this results in loose clusters that that call curdles. At around 4.7 Ph the

Yogurt is a valuable health food for both infant and elderly people. The nutritional constituents of yogurt are derived from the milk used in making it‚ those that are synthesized by the lactic acid bacteria and those that are added by the manufactures. The nutritional value of the milk protein is well-preserved during the fermentation process. Like most dairy products‚ it is a good source of protein. The milk proteins in yogurt are partially hydrolyzed and therefore become more digestible. In comparison

Lab report As part of my module Nip1002 I was required to perform a set of observational skills which included; pulse‚ blood pressure‚ respirations‚ hand washing and urinalysis and then compare them to previous results. In this lab report I am going to discuss blood pressure in detail. Procedure * Explain the procedure to the patient and gain consent * Wash hands thoroughly following the hand wash technique to prevent the transfer of bacteria * Clean equipment e.g. blood pressure cuff

“Fighting Invisible Killers” Scholastic Scope: The Language Arts Magazine January 2014 Edition‚ pages 5-9 Bacteria surround us every day. These little “bugs” are invisible to the eye and most do not harm us. Many are necessary for us to survive‚ like the bacteria in our stomachs and intestines that help us to digest food. But some bacteria are very dangerous to us. Addie Rereich became very sick in May 2011‚ when she was 11 years old. What started as something that her doctors and mother

Greek Yogurt Nutrition Greek yogurt is common in the Middle East‚ South Asia‚ the East Mediterranean‚ and Greece. Greek yogurt is made from a centuries-old technique by combining milk and live cultures (bacteria)‚ then straining out liquid whey‚ creating a thick‚ creamy yogurt without the addition of milk fat or thickeners. Straining also removes some of the lactose sugars‚ water and salt‚ which is why Greek yogurt nutrition is higher in protein and thicker than standard yogurts‚ but also lower
