Available in PDF, EPUB and Kindle. Book excerpt: The destabilized fat content of commercial "soft-serve" and packaged hardened ice creams were found to range from 18 to 100 and 8 to 11 respectively. These results confirm the findings of other investigators regarding the seriousness of this defect in ice cream especially in the "soft- serve' 1 segment of the ice cream industry. Contrary to published information, the ice cream mixes examined, both commercial and experimental., contained considerable quantities of destabilized fat ranging from 4 to 9$. Results obtained from experimental mixes and corresponding ice cream revealed that the destabilization of butterfat was proportional to the butterfat content. The greatest increase in destabilization occurred during the normal freezing operation (approximately 10 minutes). Substantial additional destabilization continued during prolonged agitation in the freezer for a period of 15 to 30 minutes, when the temperature of the ice cream was maintained at 23 C P. Destabilization of the butterfat in experimental ice cream was influenced by the type of emulsifier incorporated, but no effect was observed on mixes. Liquid type emulsifiers, which are hydrophilic, such as Tween 80^caused the greatest destabilization. In these emulsifiers the improper balance bwtween hydrophilic and lipophilic properties apparently affect adversely the stability of the butterfat emulsion. Increases in the concentration of emulsifiers caused greater destabilization. Over-emulsification, as a consequence of the concentration of unsaturated fatty acids and the presence of the polyglycol chain in the molecular structure of these emulsifiers is a possible cause. The addition of sodium oxalate, sodium hexametaphosphate and sodium tetraphosphate at two concentrations, 0.1 and 0.2, was effective in reducing the destabilized fat content of ice cream. This was especially true of sodium tetraphosphate. All the ' ddcd salts were more effective at the highest concentration added. The role of these salts in stabilizing the butterfat emulsion is discussed. The Ice cream made from butter oil as a source of fat contained a greater quantity of destabilized butterfat than ice cream made from cream. The difference however, was much less than anticipated. This indicates that a product with normal texture characteristic could be produced under the severe freezing conditions prevailing during the manufacture of "soft-serve" ice cream especially if full advantage is taken of the stabilizing effect of certain emulsifiers and stabilizing salts demonstrated in this study. Changes in the structure of ice cream and the appearance of butterfat globules, destabilized butterfat and membrane material were observed by microscopical techniques, including polarized light and electron microscope examinations. A modification of the dilution and separation method of Schulz ejg al . (1959) for measuring the destabilization of the butterfat emulsion proved to be satisfactory in this investigation.

Book excerpt: Effect of Milk Fat Globule Size on the Physical Functionality of Dairy Products provides a comprehensive overview of techniques utilized to vary milk fat globule size in fat-structured dairy products. The text aims to highlight the importance of both native and emulsified milk fat globule size in the processing and functionality of these products. Both herd managements strategies and fractionation techniques utilized to vary milk fat globule size are covered thoroughly, as are the effects of mechanical sheer processing. The influence of different size fat globules on aspects such as TAG composition, physical stability, viscosity, crystallization properties and electric conductivity are studied, as are the influences on processability and function. This Brief aims to highlight the importance of milk fat as a determinant of the microstructural, rheological and sensorial properties of fat-containing dairy products such as milk, cream, yogurt, ice cream, cheese, butter and milk chocolate. Since milk fat globules have a widely varied size distribution, controlling their size is of major importance in processing. In comprehensively covering the various methods used to vary milk fat globule size, this text serves as an important resource for those involved in dairy product processing.

Download or read book Effect of Stabilizers on Fat Agglomeration in Ice Cream During Freezing written by Inggrayani Herlambang and published by . This book was released on 2007 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Fat agglomeration has been widely known to contribute in the development of ice cream structure. this results from partial coalescence of fat globules induced by shear forces of agitation and ice crystallization during ice cream manufacturing. Preliminary study of commercial ice cream revealed that stabilizers help fat agglomeration. ice cream without any stabilizer had no cumulative % particle > 10 um, which means no fat agglomeration. the choice of emulsifier also affected the extent of fat agglomeration. in general, ice cream with egg yolks as emulsifier had lower amount of fat agglomerates than ice cream with mono- and di-glycerides as emulsifiers. To investigate the role of stabilizers and emulsifiers in more detail, ice cream mixes were prepared with a composition of 10% milk fat, 10% milk solids-not-fat (MSNF), 12% sucrose, 6% corn syrup solids (CSS) and 0.15% mono and di-glycerides (MDG). Three different gums, locust bean gum (LBG), carrageenan (Carr), and carboxy methyl cellulose (CMC), were used either singly or in combination at concentration of 0.15%, except Carr, which was added at 0.02%. The aim of this research was to examine the effects of different type of stabilizers on fat agglomeration during freezing in the presence and absence of emulsifiers. another objective of the study was to understand the influence of stabilizer on the melting resistance of ice cream. integrated light scattering with Malvern Mastersizer was used to obtain fat globules distribution and fat agglomeration. D[4,3] and cumulative % particle greater than 10 um were used to indicate fat agglomeration. Melting resistance of ice cream was examined by conducting meltdown test at ambient temperature. Dripped loss, the mass of ice cream pass through the screen, was measured as a function of time. The melting rate was calculated from the linear portion of the melting curve. Results of this study showed that choice of stabilizers influences the amount of fat aggregates formed during freezing. Ice cream with added stabiliers and/or emulsifiers showed higher extent of fat agglomeration as compared to ice cream without any stabilizers and emulsifiers. Different stabilizer gave different degree of fat agglomeration. Generally, the use of emulsifier together with stabilizer enhanced the fat agglomeration. Combination stabilizers had more effects on fat agglomeration as compared to single stabilizers because of the synergistic effect of stabilizers. Ice cream with LBG and Carr (in combination) had the highest amount of fat aggregates followed by CMC>LBG+Carr+CMC+MDG. For those with a lesser affect on fat aggregation in the ice cream, the effect was neither MDG nor stabilizer >Carr>CMC+LBG. Generally, there was less fat aggregation but more melting resistance when stabilizers were combined with emulsifier. There was no correlation between fat agglomeration and melting rate of ice creams. Overall, the studies demonstrated that stabilizers promote fat agglomeration during freezing. Further studies on ice cream structure are needed to understand the interaction of these stabilizers in the ice cream matrix.

This book was released on 2006-01-01 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ice Cream is a favourite food of millions around the world. It is a frozen mixture of a combination of component of milk, sweeteners, stabilizers, emulsifiers and flavours. Ice cream is a palatable, nutritious and relatively inexpensive food. No other food enjoys so much popularity and has as attractive a form and appeal as ice cream. Ice cream is composed of the mixture of food materials, such as milk products, sweetening materials, stabilizers, emulsifiers, flavours or egg products which are referred to as ingredients. Milk fat is of major importance in ice cream. It contributes rich flavor to the ice cream, is a good carrier for added flavor compounds and promotes desirable tactual qualities. Stabilizers are used to prevent the formation of objectionable large ice crystals in ice cream. Emulsifiers are used to produce ice cream with smoother body and texture, to impart dryness and to improve whipping ability of the mix. Flavour is considered the most important characteristics of ice cream. It has two characteristics; type and intensity. Classification of ice cream may be based on commercial terms commonly agreed upon or on regulatory composition requirements or flavor labeling standards. Commercially ice cream is classified as plain ice cream, chocolate, fruit, nut, frozen custard, confection, bisque, puddings, mousse, variegated ice cream, Neapolitan, ice milk, lacto, novelties, frappe etc. The basic step of production in manufacturing ice cream are composing the mix, pasteurization, homogenization, cooling, ageing, flavouring, freezing, packaging, hardening, storage, loading out products and cleaning of equipments. Ice cream can be mass produced and thus is widely available in developed parts of the world. Ice cream can be purchased in large cartons from supermarkets and grocery stores, in smaller quantities from ice cream shops, convenience stores, and milk bars, and in individual servings from small carts or vans at public events. Ice cream is expected to continue to expand robustly in India as purchasing power increases and as manufacturers invest in expanding the availability of ice cream in small stores. Some of the fundamentals of the book are composition of ice cream mixes, the role of the constituents, diet science and classification of ice cream, caloric content of ice cream and related products, milk fat content of ice cream, classification of ice cream and related products, artificially sweetened frozen dairy foods, ingredients of ice cream roles and properties, effect of sweetener on freezing point, influence on ice crystal size and texture, flavour and colour materials and preparation, ice cream mixer preparation processing and mix calculations, the freezing process, the freezing point of ice cream mixes, ice cream handling, cleaning and sanitation, varieties, novelties and specials etc.It is a comprehensive book which covers all the aspects of manufacturing of ice cream in various flavours.

This book was released on 2013-04-17 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food emulsions have existed since long before people began to process foods for distribution and consumption. Milk, for example, is a natural emulsion/colloid in which a nutritional fat is stabilized by a milk-fat-globule membrane. Early processed foods were developed when people began to explore the art of cuisine. Butter and gravies were early foods used to enhance flavors and aid in cooking. By contrast, food emulsifiers have only recently been recognized for their abil ity to stabilize foods during processing and distribution. As economies of scale emerged, pressures for higher quality and extension of shelf life prodded the de velopment of food emulsifiers and their adjunct technologies. Natural emulsifiers, such as egg and milk proteins and phospholipids, were the first to be generally utilized. Development of technologies for processing oils, such as refining, bleaching, and hydrogenation, led to the design of synthetic food emulsifiers. Formulation of food emulsions has, until recently, been practiced more as an art than a science. The complexity offood systems has been the barrier to funda mental understanding. Scientists have long studied emulsions using pure water, hydrocarbon, and surfactant, but food systems, by contrast, are typically a com plex mixture of carbohydrate, lipid, protein, salts, and acid. Other surface-active ingredients, such as proteins and phospholipids, can demonstrate either syner- XV xvi Preface gistic or deleterious functionality during processing or in the finished food.

Available in PDF, EPUB and Kindle. Book excerpt: Structure of Dairy Products SOCIETY OF DAIRY TECHNOLOGY SERIES Edited by A. Y. Tamime The Society of Dairy Technology (SDT) has joined with Blackwell Publishing to produce a series of technical dairy-related handbooks providing an invaluable resource for all those involved in the dairy industry; from practitioners to technologists working in both traditional and modern large-scale dairy operations. The previous 30 years have witnessed great interest in the microstructure of dairy products, which has a vital bearing on, e.g. texture, sensory qualities, shelf life and packaging requirements of dairy foods. During the same period, new techniques have been developed to visualise clearly the properties of these products. Hence, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) have been used as complimentary methods in quality appraisal of dairy products, and are used for product development and in trouble shooting wherever faults arise during manufacturing. Structure of Dairy Products, an excellent new addition to the increasingly well-known and respected SDT series, offers the reader: • information of importance in product development and quality control • internationally known contributing authors and book editor • thorough coverage of all major aspects of the subject • core, commercially useful knowledge for the dairy industry Edited by Adnan Tamime, with contributions from international authors, this book is an essential purchase for dairy scientists and technologists, food scientists and technologists, food chemists, physicists, rheologists and microscopists. Libraries in all universities and research establishments teaching and researching in these areas should have copies of this important work on their shelves.
