Both processes serve to increase the shelf life of milk and increase its hygienic safety. Pasteurized milk is subjected to a process where pathogenic microorganisms are eliminated without affecting the quality and properties of the product. However, in recent years the influence of UHT milk consumption on intestinal microflora has been studied. However, they show differences both in heating times and in organoleptic and nutritional changes. High temperature treatment affects and denatures the protein present in the milk therefore loss of protein in UHT milk is higher. Do you know the differences between pasteurized milk and UHT milk? It is a process by which the milk is heated to a temperature between 55 and 75 ° C, for a period of 17 seconds. There are two types of heating processes used for milk under pasteurization: High-temperature, short-time (HTST) and Ultra-high temperature processing (UHT). On the other hand, is UHT milk, which is subjected to temperatures of 138 ° C for a few seconds. Glob Marketing Ltd 36,109 views (For example, UHT pasteurized milk keeps for approximately 6-month shelf life under refrigeration condition) Fortification. Pasteurized milk and UTM milk are originally different products for different consumer groups. Non-refrigerated, shelf-stable milk is definitely UHT. In HTST Pasteurization, the product is subjected to much lower temperature (71.7°C, almost half of the temperature which is used for UHT method) over a long period (15 seconds) compared to UHT Pasteurization. pasteurized milk has an expiry date of 4 days from its packaging, while UHT milk is preserved for months. UHT – ultra high temperature. Pasteurized milk must be stored under refrigeration and has a relatively short shelf life. One of the following temperature-time combinations is commonly used: During the storage of milk, nutrients will be lost over time. As I have already mentioned, pasteurization takes place at temperatures below 100oC. High temperature denatures the immunologically active protein in milk, and the nutritional loss of protein in UHT milk is more than that of pasteurization. It is used for low acid (above pH 4.6) products such as UHT milk, UHT flavoured milk, UHT creams, soya milk and other dairy alternatives. Pasteurized milk has organoleptic characteristics more similar to those of raw milk in terms of conditions of smell, taste and color. Pasteurization cannot kill all microorganisms in milk, and some microorganisms that are not pathogenic to humans are left behind. Proteins and amino acids will remain unchanged in both thermal processes. This is due to the fact that it has been subjected to a lower temperature than UHT milk. However, these are sterilization methods that are not only used in the dairy industry. UHT milk contains 1 μg of folate per 100 g, while pasteurized milk contains 9 μg. Although there are slight differences in nutrition and taste, they are not worlds apart. Dr. Timothy Schultz answered. Pasteurized milk is sterilized by heating at 72-85°C for 10-15 seconds. As for UHT milk somehow depleting our gut of its endogenous flora, that is simply untrue. It’s heated to 280°F at the minimum, which means that it’s able to kill almost all of the bacteria that the normal pasteurization process may have missed (Keyword here being almost—it’s not sterile.). Why is there a chronic vitamin D deficiency? Ascorbic acid levels and vitamins B1 and B12 are reduced. No lactulose was detected in the pasteurized milk. Pasteurization does not kill all micro-organisms in milk, but is intended to kill some bacteria and make some enzymes inactive. Being a more aggressive treatment from the thermal point of view, vitamin losses occur. The first problem was solved by applying steam and pressure variations, while to solve the second problem the tetra brik was invented. In some large cities with complete cold chain conditions, pasteurized milk products also enter consumers’ tables. However, it can alter the nutritional quality of the food. UP – ultra pasteurized. Content from UHT milk package based on raw milk of pH 6.47 on the day after production. pasteurized milk has organoleptic characteristics more similar to those of raw milk. Shelf life of HTST milk is 2-3 weeks. Pasteurized Milk: Pasteurized milk has a longer shelf life. Commercial pasteurized, UHT and sterilized milk samples, and laboratory autoclaved milks, were analysed for lactulose by an enzymatic method. UHT is the process of heating milk to a temperature exceeding 135 degrees Celsius (275 degrees Fahrenheit) for one or two seconds. Pasteurized milk is sterilized by heating at 72-85°C for 10-15 seconds.UHT: Ultra High Temperature. 31 years experience General Practice. This treatment is hardly used, as it is very slow and also causes many modifications. – Classic method: temperature of 110-120oC between 15-20 minutes. Different countries have their own preference due to the production conditions and consumption habits. However, it must be consumed within a maximum period of 3 days once it has been opened. This is a relatively recent method, because it had technical difficulties, such as being able to heat and cool the milk quickly or the method of being able to store it in a sterile container that was appropriate. In the case of milk, the legislation allows for two pasteurization treatments: The heat-treated (pasteurized) milk is not only safe for human consumption but also has a longer shelf life, e.g. In terms of convenience, UHT milk is obviously better and safer. : Milk organic or regular is a source of protein/calcium. On that account, ultra-pasteurized milk has a longer shelf life than pasteurized milk. UHT: Ultra High Temperature. Caffeine and Fertility: they don’t mix well. Ultra-Pasteurized milk’s flavor is a little different from normally pasteurized milk because of the … A pasteurizer is used to carry out these treatments, which is no more (or less) than a heat exchanger. On the label, it will usually say Pasteurized. Because of this, UHT pasteurization gives you a longer “sell by” date at the store and more leeway in the fridge … For example, in France (the country where pasteurized milk technology was born), Spain, and some European countries, pasteurized milk is the main product. They do not grow at low temperature and do not survive pasteurization of milk. Your email address will not be published. The conclusions, despite not reaching the level of evidence A, speak that the consumption of this milk modifies the flora and increases the inflammation. Which one to buy depends on individual needs：. UHT: Ultra High Temperature. It improves product conservation and reduces its microbiological risk. Pasteurization is a popular method of heat treatments used to produce long-life milk and fruit juice. It is used for what is called “sterilized milk”, which is one that undergoes heat treatment after being packaged. In the market, both UTH milk and pasteurized milk are sold on the shelves. It is neither better nor worse. Pasteurized milk must be kept cold at all times, however UHT milk can remain at room temperature until the moment of opening the container. This last process is continuous flow and direct contact, which It produces a minimum alteration of the product and allows to keep it in perfect condition even at room temperature. Pasteurization: Fresh milk is heated up to 70-75 degrees Celsius for 15 seconds. UHT stands for Ultra-High Temperature. The shelf life is long enough. However, in the case of UHT milk the thing changes. When you remember to drink, it is estimated that it has not expired. The milk of goats and sheep is similar in composition to that of cows. Pasteurization is a low-temperature sterilization method invented in 1865 by a French named Pasteur. UHT Milk Produced & Packaged in France: The MoMo Story by Glob Marketing - Duration: 2:23. Raw-milk proponents will pay upwards of $10 a gallon, because they believe it is safe and healthier. The expiration date of pasteurized milk is 4 days from its packaging, while UHT milk is preserved for months. The first problem was solved by applying steam and pressure variations, and the second with the invention of tetra brik. Pasteurization vs. UHT Pasteurization is the process of heating milk to 72 degrees Celsius (161.6 degrees Fahrenheit) for at least 15 seconds. While in the Asian market, affected by multiple factors such as national conditions, milk source distribution, and consumption habits, UHT milk occupies a dominant position with its advantages of safety, convenience, and nutrition.
