Quality Assurance In Tropical Fruit Processing

Tropical and subtropical countries have become well aware of the fact, that they must make better use of their fruits. In spite of the favourable climatic conditions for the production of varieties of delicious fruits in such countries, continuously high tempemtures shorten the shelf-life of most fruits and fruit products. A tropical climate provides ideal conditions for mpid growth of spoilage microorganisms and for chemical reactions. Most of such reactions in fruits and fruit products are deteriomtive in nature causing high respiration rates, texture softening and spoilage of fruit. This causes loss of colour, flavour and vitamins, and browning of fruit products. Even though a fruit product has been rendered microbiolo gically stable, these chemical reactions continue to occur in storage, and they occur much more mpidly in a tropical climate. The processing of fruits and soft drinks is a predominate food industry in tropical and subtropical countries. Some of the large companies in such industries are partly foreign owned. They seem to be efficiently operated with adequate capital, good management, and technological competence, all of which are usually imported from the parent company. However, most of small and medium companies are locally owned, and are deficient in technology and management ability. The products are generally fair. It is rare to find a trained quality assurance manager in these companies. Processing of good fruit products, especially for export, requires sound fruit processing lines as well as good managementthat achieves internationally accept ed standards of quality.

The processing of fruits and their juices is an important internationally branch of the food industry. Many fruit pro- cessing plants are situated in the tropics or subtropics or they process fruit or fruit products from theseareas. Tropical and subtropical climates provide ideal conditions for the rapid growth of microorganisms and for chemical reactions. Most of thesereactions are detrimental to the overall quality of fruits and fruit products. This laboratory manual presents both the classical laborious methods of chemical, physical, microbiological and organo- leptical methods of analysis and the modern, sophisticated but rapid procedures of testing and analysing. Special at- tention is given to economical, rapid methods which are rea- dily available and easy to use in tropical climates.

Tropical Fruit Processing focuses on the improved food preservations methods of tropical fruits for lesser developed and developed countries. This book covers four tropical fruits, namely, guava, mango, papaya, and passion fruit. These fruits have the greatest growth potential based on the knowledge and technology acquired in their cultivation, processing, and preservation. Each chapter in this book discusses the botany, cultivars, horticulture, harvesting, handling, storage, composition, packing, and processing of the fruit. A variety of processed products from these fruits, such as jellies, jams, preserves, purees, sauces, and juices, are also covered. Furthermore, this book describes various food preservation methods including dehydration, concentration, and canning. This book is an invaluable resource for scientists, technologists, manufacturers, students, and others concerned with cultivating, processing, manufacturing, research, development, or marketing of foods.

The book consists of 19 chapters on different subjects and in different dimensions, with particular emphasis on the post-harvest handling and processing of fruits and vegetables, including mushrooms. Scope for the technology on fruits and vegetables, non-destructive methods to evaluate fresh quality, radiation preservation, chemistry of pectin and pigments and their applications, nutraceutical compounds, membrane processing of liquid fruits, dehydrated and intermediate moisture products, importance of bamboo and mushrooms as food, influence of process conditions on product quality, food additives in product preparation, packaging aspects, microbiological safety concerns, relevant analytical methods, mushroom nutraceuticals and bio-technological interventions for improvement of banana with a final note on conclusions in the last

The main aim of International Marketing, is to provide solid foundations that are useful for explanation, prediction and control of international business activities.

Now in its fifth edition, Food Science remains the most popular and reliable text for introductory courses in food science and technology. This new edition retains the basic format and pedagogical features of previous editions and provides an up-to-date foundation upon which more advanced and specialized knowledge can be built. This essential volume introduces and surveys the broad and complex interrelationships among food ingredients, processing, packaging, distribution and storage, and explores how these factors influence food quality and safety. Reflecting recent advances and emerging technologies in the area, this new edition includes updated commodity and ingredient chapters to emphasize the growing importance of analogs, macro-substitutions, fat fiber and sugar substitutes and replacement products, especially as they affect new product development and increasing concerns for a healthier diet. Revised processing chapters include changing attitudes toward food irradiation, greater use of microwave cooking and microwaveable products, controlled and modified atmosphere packaging and expanding technologies such a extrusion cooking, ohmic heating and supercritical fluid extraction, new information that addresses concerns about the responsible management of food technology, considering environmental, social and economic consequences, as well as the increasing globalization of the food industry. Discussions of food safety an consumer protection including newer phychrotropic pathogens; HAACP techniques for product safety and quality; new information on food additives; pesticides and hormones; and the latest information on nutrition labeling and food regulation. An outstanding text for students with little or no previous instruction in food science and technology, Food Science is also a valuable reference for professionals in food processing, as well as for those working in fields that service, regulate or otherwise interface with the food industry.

Consumption of food products based on or containing fruit is increasing as consumers in the developed world seek a diet which they perceive to be healthy. At the same time, developing countries are increasing their volumes of value-added fruit processing in order to earn important foreign currency. This book provides a concise, thorough and authoritative coverage of the technology of fruit processing from a worldwide perspective. Detailed coverage of the use of fruit by-products, environmental issues, quality assurance and hygiene reflect the importance of these topics. New chapters cover biochemistry and implications for processing, packaging, and quality management systems and HACCP. Food technologists, production managers and technical staff in the fruit processing industry and its equipment suppliers will find the book an important information source, while those in academic and research establishments will use it as a key reference.
