Chilled food technology has had a very significant impact on the types of food eaten by consumers during the 1980s and 1990s. This method of food preservation has satisfied the desires of people for safe, reliable, fresh products providing convenience despite the limited shelf-life. This introduction reviews the definition, range and market size of chilled food and indicates trends for the L1 Definition Foods distributed under refrigeration and sold from refrigerator cabinets have been available for many years. Although there were many new chilled product
Biscuits are small baked products made principally from flour, sugar and fat. They typically have a moisture content of less than 4% and when packaged in moistureproof containers have a long shelf life, perhaps six months or more. The appeal to consumers is determine by the appearance and eating qualities. For example, consumers do not like broken biscuits nor ones that have been over or under baked

Surface quality is another aspect of machining accuracy. It consists of the surface finish and the physic mechanical state of the surface layer. It affects the proper functioning and service life of the parts Surface Finish Machining accuracy is expressed quantitatively in machining error. Surface finish is expressed quantitatively in surface roughness. The surface roughness on a machined workpiece surface is caused primarily by the geometrical factors(cutting tool geometry and cutting
Objectives In this chapter we will look at some general features of Britain and set the scene for the more detailed examination of particular aspects of life there which are dealt with in later chapters
This 90 minutes lecture to be delivered via telelink addresses a class of mit undergraduates unrolled in Engineering Design and Rapid prototyping Course. The students have been introduced to the basic optimization concepts of design variables design space, objective function, constraints and numerical search methods. Building on this elementary basis, the purpose of the lecture is to make the students aware of a reaud range of theoretical and practical issues that arise when optimization is applied in real-life engineering. To that end a gamut of topics is presented with emphasis on the qualitative exposition rather than in-depth mathematics. The topics include
