Three Important Differences Between Our Milk and Shelf-Stable Human Milk Our milk banks process donor human milk using Holder pasteurization, a low-heat method used globally within milk banking to eliminate bacteria and viruses.1 Shelf-stable donor human milk is produced using retort processing which applies high heat and pressure, similar to canning, to sterilize the milk. So, what’s the difference? 1. Holder pasteurized donor human 2 milk retains 87% of immunoglobulin Nutrient Retention (%) A (IgA), an antibody that passes immunity from mother to infant, 100 100 compared to 11% retention in shelf- stable human milk.2 87 2. Holder pasteurized donor human milk retains 54% of the lysozyme, an 54 antimicrobial protein that kills bacteria, compared to 0% retention in shelf-stable human milk.2 11 0 3. Most importantly, no research has been published to date showing IgA Lysozyme that retort processed, shelf-stable Raw Holder Shelf-Stable donor human milk is protective against NEC for the premature infant.3 Summary Research shows that Holder Pasteurized donor human milk retains many bioactive factors and is protective against NEC. Retort processed, shelf-stable donor human milk has a high loss of bioactive factors, which may translate into different health outcomes in the medically fragile infant. More research is warranted before use of retort processed donor human milk can be recommended for fragile infants. Therefore, Human Milk Banking Association of North America’s nonprofit milk banks, and other nonprofit milk banks throughout the world continue using Holder pasteurization for donor human milk. 1.

Various types of cheese produced from raw and pasteurized milk are known worldwide. In the present work, we are interested in studying the effect of the type of milk (raw and pasteurized) of two species (cow and goat) on the yield and physicochemical characteristics of the fresh cheese. In the northeastern Algeria, on 5 cow farms and 3 goat farms; 5 raw and 5 pasteurized milk cheese manufacturing trials were conducted. The analysis of the results of the 80 samples of milk and cheese of both cow and goat species showed that the latter contained significantly more fat and protein than cow’s milk and that pasteurized milk contained more protein than raw milk. As a result, actual cheese yield of goat cheese was higher than that of cows in pasteurized and raw milk. For higher yield, our result supported the use of pasteurized milk as a raw material in the manufacture of farmhouse cheese. Keywords: cheese yield; manufacturing; pasteurized; raw milk; livestock. Practical Application: For cheese-making under small scale using milk from cow or goat: pasteurization can increase actual cheese yield. 1 Introduction In Algeria, as in all regions of the world, consumption of have been attributed to several indigenous microbiota, such dairy products like cheeses is an old tradition linked to livestock as Lactococcus spp., Lactobacillus spp., Leuconostoc spp., and farming, since dairy products are made using ancient artisanal Enterococcus spp.

The required storage conditions of the pasteurized foods, either at ambient temperature, or refrigerated (4-7 °C), are indicated. * Section 3 shows a decision scheme: should a particular food be pasteurized or sterilized? This depends on the intended storage temperature (refrigerated or ambient) after heating, the required shelf life (7 days to 4 years), the food pH (high acid, acid, or low acid), the food - water activity aW, and on the presence of preservatives such as nitrite NO2 (E250) miXed with salt NaCl, or nisin. * In Section 4, two worked eXamples are presented on how to use an F value when calculating the actual sterilization time Pt: - C.R. Stumbo’s (1973) calculation method has been manually applied, verified by computer program STUMBO.eXe, to find the sterilization time and the thiamine retention of bottled liquid milk in a rotating steam retort; - O.T. Pham’s (1987; 1990) formula method, incorporated in EXcel program “Heat Process calculations according to Pham.xls”, has been used to find the sterilization time and the nutrient retention of canned carrot purée in a still steam retort.

Federal Regulation of Raw Milk Cheese
FEDERAL REGULATION OF RAW MILK CHEESE Obianuju Nsofor PhD Dairy and Egg Branch Office of Food Safety Food and Drug Administration Background ¡ Safety of raw milk cheeses is a public health concern. ¡ The presence of pathogens in dairy products is an indicator of poor sanitation, temperature abuse, inadequate pasteurization, fermentation failure, or obtaining milk from sick animals. ¡ Raw milk has been shown to be a major source of foodborne pathogens from prevalence studies. Background cont. ¡ Consumption of contaminated raw milk products has led to several foodborne outbreaks including brucellosis, salmonellosis, listeriosis, HUS associated with E. coli 0157:H7, staph. enterotoxin poisoning etc. ¡ Between 1941 to 1944, there were outbreaks of illnesses due to the consumption of cheeses made from raw milk. ¡ By 1946, there were scientific reports indicating the survival of pathogenic bacteria in raw milk cheeses. Background cont. ¡ FDA in 1949 promulgated standards for cheese as a response to numerous foodborne outbreaks due to consumption of improperly heat treated or raw milk cheeses. ¡ In the 1960’s more challenge studies were carried out to investigate the survival of pathogens after the 60-day aging period. Regulation /Policy ¡ In 1987, FDA prohibited interstate sale or distribution of non-pasteurized dairy products to consumers. ¡ Current Federal Regulations (21 CFR 1240.61) require: l “mandatory pasteurization for all milk and milk products in final package form intended for direct human consumption” Regulation /Policy cont. Exception: ¡ Cheeses identified by standards at 21 CFR 133 et seq. may be made from raw milk. They typically have to be aged for a defined time period in order to control microbial pathogens.

A Summary of Water Pasteurization Techniques
A SUMMARY OF WATER PASTEURIZATION TECHNIQUES Dale Andreatta, Ph. D., P. E. SEA Ltd. 7349 Worthington-Galena Rd. Columbus, OH 43085 (614) 888-4160 FAX (614) 885-8014 e-mail [email protected] Last modified Feb. 6, 2007 Introduction In developing countries the burden of disease caused by contaminated water and a lack of sanitation continues to be staggering, particularly among young children. According to the United Nations Children's Fund (UNICEF) diarrhea is the most common childhood disease in developing countries. Dehydration resulting from diarrhea is the leading cause of death in children under the age of five, annually killing an estimated five million children.1 (Footnotes refer to references at the end of this document.) Contrary to what many people believe, it is not necessary to boil water to make it safe to drink. Heating water to 65° C (149° F) for 6 minutes, or to a higher temperature for a shorter time, will kill all germs, viruses, and parasites.3 This process is called pasteurization. In this document we describe several pasteurization techniques applicable to developing countries. Pasteurization is not the only technique that can be used to make water safe to drink. Chlorination, ultra- violet disinfection, and the use of a properly constructed, properly maintained well are other ways of providing clean water that may be more appropriate, particularly if a large amount of water is needed. Conversely, if a relatively small amount of water is needed, pasteurization systems have the advantage of being able to be scaled down with a corresponding decrease in cost. In other words, if you have only a little money, you can use pasteurization to get a little clean water, perhaps enough for a family but not a village.

The Study on UHT Processing of Milk: a Versatile Option for Rural Sector
World Journal of Dairy & Food Sciences 2 (2): 49-53, 2007 ISSN 1817-308X © IDOSI Publications, 2007 The Study on UHT Processing of Milk: A Versatile Option for Rural Sector Kishor Gedam, Rajendra Prasad and V.K. Vijay Centre for Rural Development and Technology, Indian Institute of Technology, New Delhi-110016, India Abstract: India is the largest milk producing country in the world. Most of the rural poor people are involved in the milk production. India has a tropical climate; milk cannot be kept for more than three hours at ambient temperature immediately after milking. Cooling equipments are not available in many parts of the country and if available, which are not affordable to rural people. Milk preservation prior to distribution and sale is major problem in India. So it is necessary to develop a new sciencitific and efficient method to overcome such problems. If low cost and highly effective technology for preservation of milk can be implemented in rural areas, it can be beneficial to rural people. Ultra-high Temperature processing (or UHT) is the partial sterilization of food by heating it for a short time, around 1-2 seconds, at a temperature exceeding 135°C and then kept inside the aseptic package. Such a high temperature required to kill spores in milk. The high temperature also reduces the processing time, thereby reducing the spoiling of nutrients and has excellent keeping qualities and stored for long period of time at ambient temperature. Aseptic packaging machines are very expensive and UHT milk depends entirely on it. There is a need to reduce its cost so that UHT processing and packaging machine can be approachable to rural poor farmers in India.

UHT Vs ESL Beverages: Advantages, Disadvantages and a Unified Testing Platform
White Paper UHT vs ESL beverages: Advantages, Disadvantages and a Unified Testing Platform Introduction The global aseptic food and beverage packaging market is derived beverages. In addition, it poses new obstacles: the expected to reach $35 billion by 2025. Some of this growth need for extra equipment, processes and technologies. This is due to the increased popularity in dairy products. This means higher processing costs which are often recouped at has fueled the demand for products with longer shelf lives a premium price, but this is not the case for milk. Therefore, and room temperature storage. As a result, the demand for many dairies have been looking for better ways to process aseptically packaged beverages has grown significantly. milk for consumer use, especially in emerging markets where milk is often distributed at ambient temperatures. Aseptic packaging and filling is a specialized process in which “Aseptic packaging and filling is Milk products are generally required product is sterilized separately a specialized process in which to be processed by thermal from the packaging, and then product is sterilized separately methods such as pasteurization, filled into sterile containers under from the packaging” as has been done for decades. extremely clean environments to Drawbacks to this are it still has maintain sterility and long shelf life. This method requires the restrictions of limited shelf life, chilled distribution, and extremely high temperatures for short bursts of time so that it must be stored refrigerated after purchase. This paper will maintains the freshness of the contents and ensures that it is look at two additional processing methods which offer some not contaminated with microorganisms.
