In particular the products have a highly granular fat phase with butter-like texture and a low butterfat content. While the creams are churnable creams with high iodine values. Creams are emulsions of the oil-in-water type, and are well known both as starting materials and intermediates in methods for the production of edible spreads, including butter and margarine. In such methods the dispersed fat phase of the cream is converted into a continuous crystallised fat phase in which a dispersed aqueous phase is present.

Frank D. Gunstone , John L. Harwood , Albert J. Extensively revised, reorganized, and expanded, the third edition of the industry standard, The Lipid Handbook reflects many of the changes in lipid science and technology that have occurred in the last decade. All chapters have been rewritten, many by new authors, to match the updated thinking and practice of modern lipid science and bring a fresh perspective to twenty years of tradition.
New contributions highlight the latest technologies utilized in today's lipid science such as chromatographic analysis and nuclear magnetic resonance spectroscopy. An entirely new chapter is devoted to non-food uses such as lipids as surfactants, cosmetics, and biofuels. Expanded sections illustrate a growing emphasis on lipid metabolism and the nutritional, medical, and agricultural aspects including human dietary requirements and disorders of lipid metabolism.
The dictionary section is vastly expanded to cover chemical structure, physical properties, and references to thousands of lipid and lipid related molecules. The handbook now includes a CD-ROM that allows instant access to tabulated and referenced information and can be searched either as the full text or by structure or substructure. Drawing from the best minds in the field, The Lipid Handbook with CD-ROM, Third Edition presents the latest technological developments and the current and future directions and applications of lipid science to the next generation of researchers.
Manufacturers use the process of hydrogenation to create trans fats in order to increase the shelf life of baked and fried foods. Ingestion of trans fats is associated with an increased risk of cardiovascular disease. A groundswell of public sentiment is causing regulatory bodies to ban the use of trans fats in foods. Alternatives to trans fats are needed now in order to preserve the freshness and provide an appealing texture of many packaged foods.
Effect of Using Different Kinds and Ratios of Vegetable Oils on Ice Cream Quality Characteristics
Margarine : Is a spread used for spreading, baking, and cooking. Margarine is made mainly of hydrogenated or refined plant oils and water. While butter is made from fat from milk, margarine is made from plant oils and may also contain milk. In some locales it is colloquially referred to as "oleo", short for oleomargarine. Margarine, like butter , consists of water-in-fat emulsion, with tiny droplets of water dispersed uniformly throughout a fat phase which is in a stable crystalline form. Margarine can be used both for spreading and for baking and cooking.
Replacements for Trans Fats—Will There Be an Oil Shortage?
The aim of this study was to develop ice cream products using different types of oils, a sensory ballot to focus on the textural attributes of new ice cream products, evaluate physicochemical properties of these products and physical measurements. Ice cream is a frozen product consumed all over the world in dairy products [ 1 ]. After the first and general definition, ice creams have been defined as food systems called polyphasic. These daily products include ice crystals, air bubbles, protein-hydrocolloid structures, a cryoconcentrated aqueous phase, emulsified fat, proteins and salts. In this regard, ice creams may be evaluated as oil-in-water emulsions [ 2 ]. In ice cream, fat and fat structure development tissue has a critical prescription for many features.

BUTTER AND DAIRY SPREADS
These guidelines are intended to provide a broad framework permitting the development of more specific group or individual standards, according to the requirements of individual countries. Fat spread: A fat spread is a food in the form of an emulsion mainly of the water-in-oil type , comprising principally an aqueous phase and edible fats and oils. Edible fats and oils: Foodstuffs mainly composed of triglycerides of fatty acids. They are of vegetable, animal, milk or marine origin.
Most of the edible fats described below are solid or semisolid at room temperature and most are from animal sources. A small number of plant fats are also naturally solid or semisolid at room temperature. Plant fats that are usually liquid at room temperature can be transformed into a solid fat if they undergo a process called hydrogenation in which hydrogen is added to the plant oil. This changes the chemical characteristics of the oil, making it solid at room temperature. The process also creates trans-fatty acids, which transforms the healthy plant oils, composed largely of unsaturated fat, into less healthy solid fats containing a high level of saturated fat. Brown butter is often used as a flavoring condiment for enhancing the taste of other foods. It is easily created by melting butter slowly so that the milk solids begin to brown, but not burn. As the butter is heated, it is transformed into a golden brown liquid with a nutty and complex flavor. If heated too long, it becomes dark and burned and takes on a very unpleasant odor and flavor.
Types of Edible Solid Fats
Of a variety of fat-and-oil products, a group of solid emulsion fat-and-oil products can be emphasized, including margarines, vegetable-cream and vegetable-fat spreads. These products were initially developed as an alternative to butter, however, their scope of application has significantly expanded at this stage of development of the food industry. It should be noted that the structure of consumption of solid fat-and-oil products has recently changed with a decrease in the proportion of consumed butter, margarines and spreads as edible products. The reason for these changes is due to a more attentive attitude of the population towards health and the fulfillment of the recommendations of the health authorities to reduce the consumption of fats, in particular, saturated fats. Despite this fact, the consumption of solid fat-and-oil products on the whole continues to grow. To a certain degree, this is due to the fact that the scope of margarines and spreads is not limited to direct consumption as a sandwich type product. Margarine products are widely used in public catering and in the HoReCa sector, as well as in the confectionery, bakery, canning and other food industries. The formulation of margarine can include both natural and modified vegetable oils, water, milk and its derivative products, as well as various food supplements.

Structuring Fat Foods
Food Industry. Food fat provides taste, consistency, and helps us feel full. Fat is a major source of energy for the body, and aids in the absorption of lipid soluble substances including vitamins A, D, E, and K.
Emulsions: making oil and water mix
Butter is made from the butterfat of milk, whereas modern margarine is made mainly of refined vegetable oil and water. In some places in the United States, it is colloquially referred to as oleo , short for oleomargarine.
Dairy Processing and Quality Assurance, Second Edition describes the processing and manufacturing stages of market milk and major dairy products, from the receipt of raw materials to the packaging of the products, including the quality assurance aspects. The book begins with an overview of the dairy industry, dairy production and consumption trends.
