Yogurt is a food product that is produced by bacterial fermentation of milk. This process of producing yogurt is carried out by bacteria Lactobacillus bulgaricus and Streptococcus thermophiles and strains of Lactobacillus acidophilus and Bifidobacteria usually referred to as starter cultures. Lactose in milk undergo fermentation by the starter cultures. The starter culture react with milk protein to give off lactic acid which converts the milk to yogurt. Apart from milk and cultures yogurt are also made with various ingredients including sweeteners, fruits, stabilizers and flavors (Tamime and Robinson, 1999).
There are various kinds of yogurt based on chemical and physical nature, flavor and production style. The chemical nature of the yogurt

Greek-style yogurt mostly hold up perfectly when heated than usual yogurt, making it ideal for cooking. It is also known as Mediterranean-style yogurt and is regularly utilized for dips, for example, Tzatziki. A set-style yogurt with 6% M.F. makes a good alternative for Greek-style yogurt (Weerathilake, et al., 2004).
The conditions in which the yogurt is produced determines the quality of the yogurt.
The standard utilized to determine the quality of the product includes physical, microbiological, chemical and nutritional characteristics of the product. It is critical to monitor all the stages of the production process from the receiving of raw material to the packaging and storage of the end product to ensure high quality products (Tamime and Robinson, 1999).
A constructive environmental monitoring system such as Hazard Critical Control Point (HACCP) is designed and implemented to monitor and prevent microbiological hazards and contamination. Environmental monitoring systems are intended to increase shelf life, safety of food and product quality which can be directly or indirectly affected by environmental
While the tube for specimen Cb turned a tannish white in the lower half of the tube while the top stayed the lavender inoculated tube color. Do to this evidence I determined that both specimens Ca and Cb cannot use the process Casein hydrolysis or Casein coagulation due to lack of soft or firm curds in both tubes. Since there was no casein curds formed, I concluded that specimens Ca and Cb also cannot perform the process of proteolysis. My conclusion is supported by the fact that there was no clearing of the medium. I have also determine that neither of my organisms can make the enzymes rennin, proteolytic or even proteases. I know my specimens cannot produce proteases due to the fact that there was no blue coloring in the tubes which means that the byproduct Ammonia was not produced to increase the pH. Since neither of my specimens can make these enzymes, I concluded that my specimens cannot break down lactose or casein. Although I did learn that specimen Cb can reduce litmus due to the evidence that the lower part of the tube turned a tannish white color with a purple ring at the top. This color change from a purple to a white means that the litmus was reduced turning it clear and leaving the white of the milk to show. Finally I know that specimen Ca cannot reduce litmus due to the fact that the tube had no change in
The best time to use this mask is in the evening because this way your skin gets about 12 hours to heal before it is exposed to the sun. Moreover, I don’t fancy the idea of walking around smelling like fruit yoghurt, so nighttime use works for me.

In certain foods there are good bacteria or probiotics that are needed. They help boost your immune system and also helps protect against bad bacteria. The different types of foods that contains good types of bacteria are: Yogurts which is fermented dairy products and contains live bacterial cultures, Buttermilk is produced by fermentation as lactic acid bacteria, and also different types of cheese, but only aged cheese have live cultural bacteria. Furthermore, prokaryotes help in the production of sour cream, pickles, olives, vinegar and sourdough bread. Why, because prokaryotes are useful to some food production by converting textures, providing flavors, manufacturing ethanol, and protection from unwanted microbes known as food preservation. Food preservation is a method that is projected to keep microorganisms out of foods, removing microorganisms from contaminated foods, and obstruct the growth and activity of microorganisms already in foods. Also, bacteria breakdown proteins and fats into a complex mix of amino acids amines, and fatty acids, which lead to processing altars, the food product.
To ensure that all food meets consumers expectation in terms of nature, substance and quality and is not misleadingly presented

One of the questions people may ask is does a label indicate the quality of a dietary supplement product. It is difficult to determine the quality of a dietary supplement product from its label but, the degree of quality control depends on the manufacture, the supplier, and others in the production process. In 2007, the FDA issued good manufacturing practices for dietary supplements, also a set of requirements and expectations by which dietary supplements must be manufactured, and prepared and stored to ensure quality. Manufacturers are now expected to guarantee the identity, purity, strength, and composition of their dietary products. For example, the GMP‘s aim to prevent the inclusion of the wrong ingredients, not to mention the addition of too much or too little of a dietary ingredient, increases the possibility of contamination, pesticides, heavy metals such as lead, bacteria, etc., and the improper packaging and labeling of a product. Another question is are dietary supplement standardized? Standardization is a process that manufactures may use to ensure batch to batch consistency of their products. In some cases, standardization involves identifying specific chemicals known as markers that can be used to manufacture a consistent product. The standardization process can also provide a measure of quality control. Dietary supplements are not

Therefore, the attention has been drawn from quantity of food to quality and safety. A gap between food demand and safe food supply becomes an urgent issue to be solved, which also affects global food market and food security.
We commonly view quality as a physical property of our product and therefore see our task as producing a product that meets these physical characteristics.
Food is a product that is rich with nutrient and can be contaminated with exposed to major source such as water, air, dust, sewage, insects and rodent (Oi Nee and Norrakiah, 2011). As a food handler they need to handle the changes in preparation techniques and food production because the fact remains whereby food is the source for microorganism which can cause illness (Oi Nee and Norrakiah, 2011).
Handling, processing, and preparation such as (cooking, cooling, reheating, holding/service) should be controlled to ensure that the food is not contaminated in any way.
Food safety is a scientific concept that describes how to handle, prepare, store in order to avoid from food born and harzard (Richard A. Sprenger, 2012). There is three big reasons for food safety. One is about the money. Illnesses from foods occur billions in each year in average at every USA’s states and also for people who run food related business, the financial damage could be a lot. Secondly, it can preserve the food’s quality at the peak. S...
At present, the market of the Malaysian fish fermented products remains to fulfill the local demand. As comparison, Thailand is reported to be the largest fish sauce exporter in the world with more than USD $13 million to US, Japan and Australia export annually (Brillantes, 1999 as cited in Sim, Chye, Anton, nd). Sim et al. (nd) proposed that the limitation of the local Malaysian fish sauce producer is due to the long fermentation time, limited technology and skill which cause low quality control of the products.
