...MAHENDRAN : QUALITY OF INSTANT GUAVA DRINK POWDER PHYSICO-CHEMICAL PROPERTIES AND SENSORY CHARACTERISTICS OF DEHYDRATED GUAVA CONCENTRATE: EFFECT OF DRYING METHOD AND MALTODEXTRIN CONCENTRATION T Mahendran Department of Agricultural Chemistry, Faculty of Agriculture, Eastern University of Sri Lanka, Chenkalady Accepted: 20th May 2010 ABSTRACT Dehydration of guava juice into powdered particles gives a considerable reduction in volume and is an effective method of prolonging the shelf life. Therefore, a research study was conducted to determine the effect of different drying methods and the addition of drying aids on the physico-chemical properties and sensory characteristics of dehydrated guava concentrate. Instant guava-drink-powder samples were obtained by dehydrating the concentrated guava juice using freeze drying, spray drying and tunnel drying techniques. Guava juice at 10.5°Brix was used to prepare the fruit powders. A significant reduction (p<0.05) in titratable acidity of 0.22% as citric acid and an increase in pH of 0.44 after drying of guava juice indicated that some acids were lost during the drying process. The oxidative loss of ascorbic acid was considerably lower in freeze drying (18.8%) compared to tunnel drying (32.2%). Spray dried powders were obtained from the guava juice with different maltodextrin concentrations as drying aids. When 30% maltodextrin was added to guava juice, the solubility of powder was 95% whereas, adding 60% maltodextrin decreased the solubility...

...CHAPTER I PROBLEM AND ITS BACKGROUND INTRODUCTION These days, the number of population has increases impulsively and according to Worldometers the real time world statistics, the current world population is about 7 billion. The population grows fast simultaneously the number of cars the people use in their everyday life. As stated in the report of Wards Auto, the global number of cars exceeded 1.015 billion as of 2010 and the OECD's International Transport Forum forecast that the number of cars worldwide would reach 2.5 billion by 2050. Nowadays, living in the community with things having high technology people always choose to do their jobs more easily. They’re always tend to depend to other people to make things easier such as cleaning their cars. They prefer on going to car wash to pay for cleaning their cars rather than cleaning it themselves because, going to carwash makes them lives more easily and at the same time they also treat their cars. Today's modern industrial environment the surface of a vehicle is subjected to daily abuse. The sun beats down on your car all day every day, pollutants and dirt deeply embed themselves into your paint, and minute slivers of metal become lodged into your paint which eventually rust. If you have owned a white vehicle or have observed one then you may have noticed specks of rust. Those metal slivers are the cause. Car washing techniques vary amongst individual vehicle owners. Car washing is an essential function of preventive...

...The Xtra Vacum 175 May 2007 The Xtra Vacum 175 J. White, a senior product manager at XtraVacum, was excited as he lifted the prototype of a dry piston vacuum pump out of its shipping carton. Management of XtraVacum's new parent company, KPO GmbH, had decided to test its ability to penetrate new market segments within the United States (U.S.). Whereas KPO marketed the 125 under its own name as a platform product to the scientific laboratory and health care segments, XtraVacum would sell it as a derivative product in previously untapped application segments. The division’s vice president, L. Will, had named White to head up a team charged with finding new segments for and then commercializing the 125. White looked forward to the challenge. Success would bring recognition from KPO's senior management. As he placed the steel gray device on his desk, White recited to Will all the product information he could recall. “The Xtra Vacum 175 Dry Piston Vacuum Pump is a fractional horsepower, injection-molded aluminum pump, with a pumping speed of 1.6 cubic feet per minute (CFM). The pump weighs 16.5 pounds. The Xtra Vacum 175 is a reconfigured compressor outfitted with a screen over its input nozzle to catch contaminants. Because it is a compressor, the Xtra Vacum 175 can run longer and cooler than conventional vacuum pumps. This enables the Xtra Vacum 175to function more efficiently at lower pressure levels than competing products. And, the fact that it is injection-molded means that...

Together they are synonymous with innovation and legal battles against established rivals. James Dyson was born in Norfolk in 1947. He studied furniture design and interior design at the Royal College of Art from 1966 to 1970 and his first product, the Sea Truck, was launched while he was still Courtesy of Dyson. studying. Dyson’s foray into developing vacuum cleaner technology happened by chance. In 1978, while renovating his 300-year-old country house, Dyson became frustrated with the poor performance of his conventional vacuum cleaner. Whenever he went to use it, there was poor suction. One day he thought he would find out what was wrong with the design. He noted that the appliance worked by drawing air through the bag to create suction, but when even a fine layer of dust got inside, it clogged its pores, stopping the airflow and suction. In his usual style of seeking solutions from unexpected sources, Dyson noticed how a nearby sawmill used a cyclone – a 30-foot-high cone that spun dust out of the air by centrifugal force – to expel waste. He reasoned that a vacuum cleaner that could separate dust by cyclonic action and spin it out of the ...

...Pentachlorophenol (PCP) in wood treatment 1.Introduction Wood is a hard, fibrous structural tissue found in the stems and roots of trees and other woody plants. It has been used for thousands of years for both fuel and as a construction material. It is an organic material, a natural composite of cellulose fibers (which are strong in tension) embedded in a matrix of lignin which resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also mediates the transfer of water and nutrients to the leaves and other growing tissues. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or wood chips or fiber. The Earth contains about one trillion tonnes of wood, which grows at a rate of 10 billion tonnes per year. As an abundant, carbon-neutral renewable resource, woody materials have been of intense interest as a source of renewable energy. In 1991, approximately 3.5 billion cubic meters of wood were harvested. Dominant uses were for furniture and building construction. The wood-preserving industry treats lumber with various chemicals to protect against insect damage and decay. Chemically preserved wood is used in products for outdoor use such as railway ties...

...TO GO (CASE 11) 1. Sathers’ company objective was to be one of the first companies to produce a healthy zip lock package filled with nuts and natural snacks. The objective was to tap into the market of people who led busy lives and wanted to eat a snack in a package that was resealable to enjoy at a later time. Since the Sathers’ nuts and snacks weren’t as well-known as their candy, they were able to build stronger brand awareness that was introduced through their Snacks to Go line. 2. In developing Snacks To Go, Sathers’ product conducted a market development strategy. His product, which was ultimately selling healthy snacks, was already in place but he was selling to different kind of customer. The customer he was selling to was the one on the go. With his innovative zip lock resealable bag it appealed to a new market, which would put this snacks to go in the Market development. It can also be used as a penetration to the existing customers who previously enjoyed nuts but now can enjoy the convenience of the snacks in a busy setting. 3. Their study revealed, “that most consumers who preferred resealable packaging would switch brands and pay more for the food protection, convenience, and freshness that resealable packaging offered.” In their case, over half of the their respondents preferred nuts in a resealable packaging, and for those who ate nuts more often, most “believed that it was important to preserve the freshness of the food, to keep it from drying out and...
