Dairy industries use milk to produce a wide variety of processed products, including fluid milk, cream, butter and fermented dairy products like cheese and yogurt. Relative to other food sectors, dairy industries produce substantial environmental footprints at all steps of the value chain, from the production of feed for dairy cows to the distribution of milk and milk products. For instance, cheese is associated with a greenhouse gas emission of 5.9kg CO2 equivalents/kg, compared to 0.17kg CO2 equivalents/kg for peanut butter. However, the dairy industries have made significant efforts in utilizing the by-products of milk product and processing, yielding both economic benefits and a reduction in wastage. In particular, skim milk, a by-product of cream separation, and whey, a by-product from cheese production, have received much attention due to their high commercial value. This paper discusses the efficient and effective conversion of milk production and processing by-products into valuable ingredients Skim milk is obtained as a by-product of cream separation from whole milk. Due to its negligible fat content (0.02%, compared to 4.0% in whole milk) and hence unpalatability, skim milk was previously considered unsuitable for human consumption and hence used as an animal feed, the advent of spray drying led to its wide utilization as skim milk powder; the process allows for shelf life extension and economical transportation due to the reduction in weight and volume. Skim milk powder has been incorporated into many processed food products such as soups, sauces, bakery and confectionery products, and recombined evaporated milk. A wide range of milk protein products can also be produced from skim milk by varying the processing conditio... ... middle of paper ... ... with lactic acid bacteria (e.g. Lactococcus lactis subsp. Lactis) and aroma-producing culture (e.g. Leuconostoc cremoris). Methods have been developed to produce lactic butter without yielding acidic buttermilk, which has little market value in comparison to sweet buttermilk. In the NIZO process, a lactic starter permeate is worked into sweet butter after churning, leading to production of sweet buttermilk that is highly resistant to autoxidation. Buttermilk has been found to possess potential health benefits. It is abundant in biologically active membrane-derived lipids (e.g. anticarcinogenic and anticholesterolemic), such as glycosphingolipids and gangliosides. Proteins in milk fat globular membranes (e.g. butyrophilin) have also been found to possess anticancer and antimicrobial properties, and may play a role in some diseases like autism and multiple sclerosis.
The essay establishes the existing United States regulations, which is a huge result of many medical incidents which the federal and state government analyzes for the safety of the people, whom have many concerns that are placed upon raw milk cheese. Bilger also reflects upon the growing market of raw milk products, as well as the potential re-appearance for upcoming dairy farms and artisanal cheese manufacturers, which will at least justify the government cost-charge and cost-benefit analysis examining the safety of all the raw milk
Milk is the first food of mammals, providing all the necessary nutrients for survival and initial growth until weaning (Velten 10). It is only a small percentage of the world’s population that actually drinks milk. Most people prefer processed dairy products, such as butter, cheese and yogurt. Cow’s milk is probably the most controversial of foods. Its qualities and associated

Since the beginning of time, people have been drinking milk. Even today you will find a gallon of milk in almost every refrigerator in America. Milk is, and has always been, a staple of our diet. Because it contains essential proteins, carbohydrates, fats, minerals and vitamins, milk is considered one of nature's perfect foods. Unfortunately, throughout the last century milk has been subjected to many forms of modern processing practices, which deprive milk from many of its natural qualities and benefits. Therefore many essential vitamins and enzymes are lost. Processing milk has altered one of nature’s perfect foods and changed it into something nature did not intend. Because of the abundant health benefits in raw milk, this report will explain why it should be made legal for consumers to buy throughout the United States.
Unpasteurized milk or dairy product is also a factor to a body's health because unpasteurized dairy can be vehicles for the spread of pathogenic microorganisms (Cancer Prevention Coalition). Also IGF-1 is not destroyed in the pasteurization process; the pasteurization process actually increases IGF-1levels in milk. IGF-1can also be absorbed into the bloodstream and effect other hormones (Cancer Prevention Coalition). Pasteurization also cuts in half the value of calcium milk could potentially have. The nutritional quality of milk and cheese is altered in the pasteurization process and fat is increa...
Got milk? If you do, you are at risk of cancer, osteoporosis, calcium deficiency, diabetes, heart disease, and atherosclerosis (PCRM). You might be thinking that I have gone completely mad. Of course milk is good for health; we all grew up drinking milk. We are told by the ads, the campaigns, and the culture that milk is good for us. We learnt about the importance of drinking milk and consuming dairy products in our health education class. In fact, they are in the food pyramid! The truth is milk does harm to you body, the word “milk” isn’t as comforting as it sounds.
The first thing to consider when looking into the production of animal products is what the animals rely on: food. The production of animal feed includes the use of gr...
The idea of pasteurizing milk bagan in the 1920s, and later became an aspect of everyday life in the 1950s. Milk that has undergone this process is normally prefered since it is sterilized, therefore lowering the chance of human illness. However, it’s not the 1950s anymore, and the idea of pasteurizing milk has lost its luster for the people that now prefer raw milk. Unlike the milk that most Americans consume, raw milk has not been pasteurized, or quickly heated to a high temperature to kill harmful bacteria. In raw milk, these bacterias haven’t been removed, leaving people at risk. E. Coli, salmonella, and listeria are only some of the bacteria that raw milk carries, all of which can cause sickness, or even death. Common affects of consuming raw milk are diarrhea, stomach cramping, and vomiting, but it's the rare ones: kidney failure,paralysis, and death that causes raw milk to be illegal in half of the states and illegal to carry over state lines in its final form. Nevertheless, people still actively seek out and consume raw milk because they believe its nutritional values to be greater. Controversies surround this topic on whether organic food

The production of beef produces requires a lot of energy and leaves a huge carbon footprint on planet earth. The process of producing beef goes far beyond raising cattle. It includes heavy water use, immense amounts of land to grow grain and/or corn, and requires an almost endless amount transportation. We have to consider not only the amount of land the cattle physically occupy, but also the amount of land used to grow the huge amount of food they require. To put it into perspective, the production of beef uses “30% of the earth’s land mass” (Peta 2013). In addition, it takes 31.5kWh of energy to produce 1lb of beef, approximately 58lbs of CO2 emissions (Federal Register 2010). Speaking of energy, the amount of grain fed to cattle is staggeringly high. Including beef cattle and dairy cattle if all that feed “were consumed directly by people, the number of people who could be fed would be nearly 800 million" (Pimentel, David 2014). And yet another aspect of this, perhaps an externality effect on the environment is deforestation, land dehydration, and contamination of water sources from runoff.
Pasteurization is a process that kills microbes mainly bacteria in food and drink such as milk, juice and others. Louis Pasteur was the first to discover inactivation of microorganisms by heating for the prevention of spoilage of wine in 1860 (Pescott et al., 1990). The purpose of pasteurization is not to sterilize a substance but to eliminate the disease causing pathogens. In food industry, particularly in dairy farming, many heating processes are present among the different types of fluids. Processes like sterilization, chilling of milk and pasteurization are strictly required to be cheap.
Food manufacturers use chemical in food processing because of huge economical profit. It is always cheaper to make low quality food rather than healthy food. Food manufacturers’ objectives are to find cheap methods to gain higher profit. The application of techniques such as pasteurization, fermenting and pickling are often use in food companies to prevent food from spoiling ahead of time. Their intention is to stock the food for a long period of time without worrying about early deterioration that can lead to major financial loss. Food companies use antibiotics in chicken, and steroids in cow to stimulate their growth. In an experiment, it was shown that injection of growth hormone in cow improves and stimulates milk production (Baldwin, 1995). Companies’...
Cheese is a very famous food that is can be used in many dishes for example main course and desserts. Cheese is a food that is made from a milk based. This milk can come from various sources for example cows and goats. Water content is remove fully from the milk. The function of this process is to improve and concentrated the protein, fat and other nutrients in the cheese. It also use to increase the life time for the cheese. The cheese making is one of the examples for the biotechnology.
Cocoa butter has a cocoa flavor and aroma. Cocoa butter is obtained from whole cocoa beans, which are fermented, roasted, and then separated. Chocolate liquor is pressed to separate the cocoa butter from the cocoa solids. The Broma process is used to extract cocoa butter from ground cocoa beans. Fourth, hazelnut is the nut of the hazel and therefore includes any of the nuts deriving from species of the genus Corylus, especially the nuts of the species Corylus avellana. It also is known as cobnut or filbert nut according to species. The nut happens to falls out of the husk when ripe, around 7 to 8 months after pollination. The kernel of the seed is edible and used raw or roasted, or ground into a paste. The seed has a thin, dark brown skin, which sometimes is removed before cooking. Fifth, Skimmed milk, or skim milk, is made when all the cream is removed from whole milk. It tends to contain around 0.1% fat. Traditionally, the fat was removed naturally from milk due to gravity. The quicker, modernized way of making low-fat and skim milks is to place the whole milk into a machine called a centrifugal separator, which spins some or all of the fat globules out of the milk. Skimmed milk is composed of choline, fatty acids, glycerol,
