This book was released on 2013-11-09 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the period of about five years since the first edition of this book appeared, many changes have occurred in the fruit juice and beverage markets. The growth of markets has continued, blunted to some extent, no doubt, by the recession that has featured prominently in the economies of the major consuming nations. But perhaps the most significant area that has affected juices in particular is the issue of authenticity. Commercial scandals of substantial proportions have been seen on both sides of the Atlantic because of fraudulent practice. Major strides have been made in the development of techniques to detect and measure adulterants in the major juices. A contri bution to Chapter 1 describes one of the more important scientific techniques to have been developed as a routine test method to detect the addition of carbohydrates to juices. Another, and perhaps more welcome, development in non-carbonated beverages during the past few years is the rapid growth of sports drinks. Beverages based on glucose syrup have been popular for many years, and in some parts of the world isotonic products have long featured in the sports arena. A combination of benefits is now available from a wide range of preparations formulated and marketed as sports drinks and featuring widely in beverage markets world-wide. A new chapter reviews their formulation and performance characteristics. Another major trend in the area of fruit-containing non-carbonated bever ages is the highly successful marketing of ready-to-drink products.

Download or read book Modern Techniques for Food Authentication written by Da-Wen Sun and published by Academic Press. This book was released on 2008-06-12 with total page 714 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the increasing awareness of food safety and quality, consumers continuously demand the reassurance of origin and content of their foods. Furthermore, manufacturers must be able to confirm the authenticity of components of their products in order to comply with government legislation. Protection of the rights of consumers, genuine food processors, and prevention of fraudulent or deceptive practices and the adulteration of food is an important and challenge facing the food industry. Rapid scientific and technological advances in the determination of food authenticity have taken place in recent years and Modern Techniques for Food Authentication focuses on many of those novel techniques. Including coverage of various spectroscopic technologies, methods based on isotopic analysis and chromatography, DNA, enzymatic analysis, electrophosresis and thermal methods, this book provides a valuable, international resource on the latest developments in food authentication. A comprehensive overview of authentication techniques and technology Written by an international group of academic and professional peers Provides an excellent complement to more general books on food safety

Download or read book P1 38 02 Nutritional Composition of Commercially produced 100 Orange Juice Reveals Large Variability in Vascular Health Bioactive Hesperidin written by Johan De Rycker and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: It is well-accepted that fruits contain a wide array of nutrients and bioactive substances which may contribute towards the prevention of chronic disease. Citrus fruits, as well as their juices, are recognised for their rich polyphenol content, specifically the flavanones; hesperidin, naringin and narirutin. Citrus fruits and juices are also rich in vitamin C and provide a source of folate, potassium and provitamin A.Randomised controlled trials have reported significant improvements to vascular function and blood pressure following consumption of 100% orange juice (OJ) with the effects potentially mediated through hesperidin and/or potassium (which has an EU claim for supporting normal blood pressure). Further clinical research may be facilitated by up-to-date information on the composition of OJ.By auditing more than 350 fruit processing companies worldwide, the non-profit organisation SGF International collects authentic OJ samples for regular compliance testing. Samples of unpasteurized OJ from the production line are removed by trained staff immediately post-extraction and frozen at -18u00b0C within a few minutes. The samples are posted in this state to accredited laboratories where key nutrients and bioactives are tested. SGFu2019s Database of Authentic Samples (2018) provides the following data (mg/litre) as sample size, mean, standard deviation, minimum, maximum for hesperidin (231, 520, 175, 109, 1160), L-ascorbic acid (615, 450, 98, 120, 721), potassium (1242, 1758, 204, 1197, 2340), total carotenoids (575, 7, 3, 2, 21) and pectins (1043, 334, 132, 19, 932).On average, there was more hesperidin in OJ than vitamin C, giving an estimated composition of 78 mg hesperidin and 67.5 mg vitamin C per 150 mL serving. Samples from Chinese producers had the greatest variability in hesperidin (109-1160 mg/L) while samples from Argentina, South Africa and Spain had the smallest variability. When OJ from not-from-concentrate (n=62) and concentrate (n=169) were compared, mean levels of hesperidin were significantly higher in the not-from-concentrate juice (576 mg/L [sd 228 mg/L] vs. 500 mg/L [sd 146 mg/L]; P=0.016; Welchu2019s t-test).Vascular benefits in humans have been detected at OJ intakes of 500 ml/day or hesperidin intakes of 290 mg/day (Morand et al. 2011). From a quality assurance perspective, the AIJN sets an acceptable range for hesperidin as 250-700mg/L. Raising the upper cut-off could increase the hesperidin content of commercially-available OJ with potential benefits for vascular health.Morand C et al.

Download or read book Production Systems and Processing Effect on Phytochemicals in Citrus Fruits and Their Analytical and Isolation Methods written by Ram Mohan Uckoo and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The emerging scientific evidences on the role of food components in prevention of several chronic diseases are the momentum for shifting from a traditional focus on production to enhancement of nutritional quality. To further understand the role of these phytochemicals this dissertation describes the development of rapid analytical and isolation methods, and the effect of production systems and processing techniques on the levels of phytochemicals in citrus fruits. In the first study, a simultaneous high performance liquid chromatography (HPLC) method for the rapid analysis of amines and organic acids was developed. The simultaneous extraction and analysis of samples provides an economical method for analyzing a large number of samples. In the second study, rapid separation method of potent health beneficial phytochemicals such as polymethoxyflavones from citrus peels using flash chromatography was developed. Using the developed method, five polymethoxyflavones were separated and isolated with high purity in gram level quantity. In the third study, the levels of phytochemicals in organically and conventionally grown lemons and their storage at market simulated conditions were determined. Results suggest that organically produced citrus fruits have higher content of organic acids and flavonoids than conventionally produced. The fourth and fifth study determined the influence of household processing (blending, juicing, hand squeezing techniques) and emerging processing (high pressure processing [HPP], thermal processing) on the phytochemicals content of "Rio Red" grapefruits. Fruits processed by blending had significantly higher levels of flavonoids, furocoumarins and limonin compared to juicing and hand squeezing, while HPP enabled in extending the shelf life of the processed juice without any adverse effects. Therefore, consuming grapefruit juice processed by blending may provide higher levels of health beneficial phytochemicals. The sixth study describes a rapid flash chromatography method for isolation of PMFs and furocoumarins from citrus industrial by products such as peel oil. In the seventh study the developed method was applied to isolate 10 different phytochemicals from an unexplored citrus species, Miaray mandarin (Citrus miaray TAN.). Among them, the 5,7,8,3',4' pentamethoxyflavone was isolated for the first time from the genus Citrus.
