Description

Pasteurization and other heat treatments of milk such (sufficient time/temperature combinations) that they practically eliminate specific pathogens. UHT treatment is normally in the range of 135 to 150 °C in combination with appropriate holding times necessary to achieve commercial sterility. Other equivalent conditions can be established through The First Book on Modern Food Preservation Methods (1810)". Historyofscience.com. 29 September 2009. Archived from the original on 1 January 2011 . Retrieved 19 March 2014. The service water is circulated by the centrifugal pump (5) via the heater (3) and the heating section of the pasteurizer. The system uses regenerative heating, i.e., it uses the heat of the already pasteurized milk to heat up the incoming chilled milk. The chilled milk, in a counter-current flow, cools down the pasteurized milk.

The flow diversion valve is located between the holding cell and the booster pump. If the temperature drops, the valve diverts the flow. The booster pump is not stopped, but other valves around the heat exchanger will automatically be positioned so that the milk in the regenerative and cooling sections will be circulated to maintain the right pressure in the plant. This also preserves a proper temperature balance. When the heating conditions are acceptable, the process can be resumed without intermediate cleaning. There are customers who will consume skim milk only while there are those who will take low-fat milk. There are those who will take standardized milk while there are those who prefer high-fat milk.

"The Johns Hopkins Raw Milk Study – A Campaign for Real Milk". A Campaign for Real Milk. The process is intended to destroy or deactivate microorganisms and enzymes that contribute to food spoilage or risk of disease, including vegetative bacteria, but most bacterial spores survive the process. [1] [2]Every component in the line should be dimensioned to cause the lowest possible pressure drop. A pressure drop involves an increase in flow velocity, ei The mean log 10 reductions and temperatures of inactivation of the major milk-borne pathogens during a 15-second treatment are: Flash pasteurization: Also known as high-temperature short time (HTST) pasteurization. Heat the milk to between 72°C to 74°C for 15 to 20 seconds. Clean and sanitize containers. Clean a milk container thoroughly with hot water and soap before using. For best results, sterilize a heat-safe container after cleaning by submerging it in hot water (at least 170ºF / 77ºC) for 30 to 60 seconds. ml, and 40% cream 3500 µg/ml). Application of pre-heating: The level of alkaline phosphatase is decreased with heat, such as at temperatures typically applied in separation and in thermization.

The combined effects of two or more treatments may be considered additive provided they comprise a single continuous process. Pearce, Lindsay (2002). "Bacterial diseases – The impact of milk processing to reduce risks". Bulletin of the International Dairy Federation. 372: 20–25. ISSN 0250-5118. Archived from the original on 29 July 2017 . Retrieved 23 June 2017. Much later, in 1768, research performed by Italian priest and scientist Lazzaro Spallanzani proved a product could be made "sterile" after thermal processing. Spallanzani boiled meat broth for one hour, sealed the container immediately after boiling, and noticed that the broth did not spoil and was free from microorganisms. [2] [6] In 1795, a Parisian chef and confectioner named Nicolas Appert began experimenting with ways to preserve foodstuffs, succeeding with soups, vegetables, juices, dairy products, jellies, jams, and syrups. He placed the food in glass jars, sealed them with cork and sealing wax and placed them in boiling water. [7] In that same year, the French military offered a cash prize of 12,000 francs for a new method to preserve food. After some 14 or 15 years of experimenting, Appert submitted his invention and won the prize in January 1810. [8] Later that year, Appert published L'Art de conserver les substances animales et végétales (" The Art of Preserving Animal and Vegetable Substances"). This was the first cookbook of its kind on modern food preservation methods. [9] [10] Store in the refrigerator. Pasteurization only kills 90 to 99% of bacteria in the milk. You still need to refrigerate the milk to prevent the bacteria population from growing to unsafe levels. Seal the container tightly and keep it away from light. [7] X Research source Prepare an ice bath. The faster you cool your milk after pasteurization, the safer and tastier it will be. Fill a sink or large tub with cold water and ice so you'll be ready to go.

heat can be supplied externally or internally in heat exchangers or within a pasteurizer. Due to the noncontinuous flow conditions, heating and cooling takes longer and will add to the effect (cumulative).

According to a systematic review and meta-analysis, [51] it was found that pasteurization appeared to reduce concentrations of vitamins B12 and E, but it also increased concentrations of vitamin A. Apart from meta-analysis, it is not possible to draw conclusions about the effect of pasteurization on vitamins A, B12, and E based merely on consultation of the vast literature available. [51] Milk is not an important source of vitamins B12 or E in the North American diet, so the effects of pasteurization on the adult daily intake of these vitamins is negligible. [52] [53] However, milk is considered an important source of vitamin A, [54] and because pasteurization appears to increase vitamin A concentrations in milk, the effect of milk heat treatment on this vitamin is a not a major public health concern. [51] Results of meta-analyses reveal that pasteurization of milk leads to a significant decrease in vitamin C and folate, but milk is also not an important source of these vitamins. [54] [53] A significant decrease in vitamin B2 concentrations was found after pasteurization. Vitamin B2 is typically found in bovine milk at concentrations of 1.83mg/liter. Because the recommended daily intake for adults is 1.1mg/day, [52] milk consumption greatly contributes to the recommended daily intake of this vitamin. With the exception of B2, pasteurization does not appear to be a concern in diminishing the nutritive value of milk because milk is often not a primary source of these studied vitamins in the North American diet. The milk is replaced by water and the pasteurizer shuts down when circulation has continued for a pre-determined time. Feed pump

As milk often contains solid matter such as dirt particles, leucocytes (white blood corpuscles) and somatic cells (of udder tissue), it must be clarified. Since pasteurization is less likely to be effective if bacteria are hidden in lumps and particles in the milk, clarification must take place before heating. Milk can be clarified in a filter or, more effectively, in a centrifugal clarifier. Process-related – concerning plant capacity, selection of components and their compatibility, degree of process control, availability of heating and cooling media, cleaning of processing equipment, etc.

Medical equipment, notably respiratory and anesthesia equipment, is often disinfected using hot water, as an alternative to chemical disinfection. The temperature is raised to 70°C (158°F) for 30 minutes. [36] Pasteurization process [ edit ] General overview of the pasteurization process. The milk starts at the left and enters the piping with functioning enzymes that, when heat-treated, become denatured and stop functioning. This prevents pathogen growth by stopping the functionality of the cell. The cooling process helps stop the milk from undergoing the Maillard reaction and caramelization. For a flow rate of 20 000 litres/hour and a pipe size of 2.5" (63.5 mm), a velocity of 1.75 m/s, the graph indicates a pressure drop, or loss of head, of 0.4 metre over the fully open valve. Service media requirements are calculated after the plant design is agreed upon. Thus, the temperature programme for pasteurization must be known, as well as the specifications for all other areas where heating and cooling are needed (cold storage, cleaning systems, etc.), before the number and power of electrically operated machines, number of pneumatically operated units, working hours of the plant, etc. can be determined. Such calculations are not presented in this book. Choice of equipment container at normal non-refrigerated conditions at which the food is likely to be held during manufacture, distribution and storage. Milk pasteurization is the process of heating milk (or milk product) to a predetermined temperature for a specified period without re-contamination during the entire process.There are many aspects to be considered when a process line is designed. They can vary and be extremely complex, which places considerable demands on those responsible for the preliminary planning. Project engineering always involves a compromise between different requirements such as: It is important to standardize milk fat to ensure that you end up with a product of consistent quality in the market. Different consumers prefer different products. Standardization is necessary to ensure that all the customers are catered for. Again, it is during the process of standardization that you get to separate the butterfat that is used for making cream and other fat-based products such as butter and ghee. Carlisle, Rodney (2004). Scientific American Inventions and Discoveries, p. 357. John Wiley & Songs, Inc., new Jersey. ISBN 0-471-24410-4. Hot water or saturated steam at atmospheric pressure can be used as the heating medium in pasteurizers. Hot steam, however, is not used because of the high differential temperature. The most commonly used heating medium is therefore hot water, typically about 2 – 3 °C higher than the required temperature of the product.
