Book excerpt: Grapes and wine production residuals, containing grape skins, seeds and stems,represent important sources of phenolic compounds. Red wines are rich inphenolic antioxidants while white wines generally show lower (poly)phenolic content and antioxidant activity. The main difference in the production of white and red wines is the fermentation step. The fermentation of red grapes includes maceration, i.e. it takes place in both liquid and solid parts of thegrape. In the case of white wines, the must is clarified before the fermentation starts, cultured yeasts are added to convert the must to wine andantioxidant sulfur dioxide is inserted to protect the wine. The objective of the PhD research was to study antioxidant potential of white grape phenolics both in raw material and fermentation products. First, the standardsof phenolic compounds commonly found in white grapes and wines were tested for their antioxidant and antiradical activity. All tested compounds except apigenin showed strong antioxidant and antiradical properties. Afterwards, conventional solid-liquid extraction (CE) and pressurized liquid extraction (PLE) of phenolic compounds from grape seeds were performed. The optimal extraction conditions were investigated and extracts were analyzed in order to determine their total phenolic content, individual phenolic compoundsand antiradical potential. Two different drying methods (hot air and freeze drying) were applied to the seeds. Solvent efficiencies of water, ethanol and water-ethanol mixtures were compared at different temperatures. Inaddition, supercritical fluid extraction (SFE) with CO2 was investigated as the technique for the recovery of phenolic compounds and for the pretreatment of white grape seed samples. Both CE and PLE gave extracts rich in phenolic compounds with good antiradical properties and, generally, the best results were obtained with PLE at 130°C. At the end, the influence of maceration process on the content and the activity of grape phenolic antioxidants in white wines was studied. For such a purpose, six commercially available macerated white wines from Italy and Croatia were analyzed. In addition, eightnon-macerated wines from the same region and variety were studied and compared to macerated wines. The experiments have shown that the maceration process increases the total phenolic content and antiradical activity of the wine. It enables the production of white wines rich in phenolic compounds and with strong antiradical properties in completely natural way using only the grapes and without addition of any chemical agents.

This book was released on 2012 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Muscadine grapes are native to southeastern parts of the United States. They are widely processed into juices and wines. They contain high amounts of polyphenols that are generally known to have high levels of antioxidant activity, offering potential health benefits. Since the juice is always consumed after processing, the effect of processing on the antioxidant activity and other quality parameters needs to be determined. Unpasteurized Muscadine grape juice was obtained from Paulk vineyards in Georgia. Juice was thermally pasteurized at 85 °C for 53 s. To obtain microbiologically safe conditions for High Pressure Processing (HPP) of juice, microbial equivalence between thermal processing and HPP was established using Saccharomyces cerevisiae strain. For HPP, the juice was vacuum packed in pouches and processed at pressures ranging from 275 - 425 MPa for 5 - 15 min. Total phenolics in juice samples were measured using Folin - Ciocalteu method. The antioxidant activity was determined using chemical antioxidant assay - Oxygen Radical Absorbance Capacity (ORAC) and biological antioxidant assay - Cellular Antioxidant Activity (CAA) assay. 'Difference from Control' sensory test was performed to find the overall difference in the sensory quality of unpasteurized and processed juice samples. The effect storage time and temperature on total phenolics, ORAC value, color and ellagic acid content was determined for the processed juice samples. Results showed no significant change in total phenolics and ORAC value, after processing. Cellular antioxidant activity increased significantly in high pressure processed sample as compared to thermally processed sample. No overall difference was perceived during sensory evaluation between any of the samples. During storage, total phenolics and ORAC value decreased with time, but the choice of process had no impact on these parameters. Browning index (BI) calculated from measured color indicators, was different for thermally processed and high pressure processed samples, but both samples showed an increase in the BI with time. Ellagic acid content was found to be higher in high pressure processed storage samples compared to unpasteurized and thermally processed samples. Thus, HPP did not offer any special benefit over traditional thermal processing for Muscadine grape juice.

Book excerpt: Phenolic compounds present in grapes and wines may play a positive role in human nutrition, related to their positive protective action towards reducing the risks associated with heart disease and the scavenging properties toward free radicals associated with degenerative diseases. Noble and carlos grapes were either cold pressed at room temperature or hot pressed at 43 C followed by collection of their free run juices and fermentation to wines. Resulting pomaces were dried at 37 C, 49 C, and 60 C by convection and vacuum ovens. Juices, wines and pomaces were tested for total phenol content and antioxidant capacity via the oxygen radical absorbance capacity assay (ORAC). Carlos grape skin, seed and delipidized seed extracts were analyzed to determine their antioxidant activity in a safflower oil model system. Carlos grape skin and seed were dried at 60 C and extracted using ethyl acetate and water. The antioxidant activity of carlos grape extracts were compared to tert-butyl hydroquinone (TBHQ) and propyl gallate (PG). Three levels (60, 180 and 300 milliequivalents of gallic acid) of extract were tested in an oil model system using the oxidative stability instrument (OSI) and conjugated diene, to measure levels of antioxidant activity. The objective of this research was to study the effects of processing on muscadine juices, wines and pomaces and to study the antioxidant properties of muscadine extracts in a lipid model system. Results of processing effects indicated that noble hot pressed juice and noble wine showed a significantly higher level of total phenols and total antioxidant capacity than for carlos samples. Total phenols indicated that all noble pomaces were significantly higher than carlos pomaces. Antioxidant capacity indicated no significant difference between noble and carlos dried samples. Analysis by OSI showed that ethyl acetate seed extracts at a level of 300 milliequilvalents of gallic acid was significantly higher than TBHQ and PG. Oxidative inde.

Book excerpt: As an applied science, Enology is a collection of knowledge from the fundamental sciences including chemistry, biochemistry, microbiology, bioengineering, psychophysics, cognitive psychology, etc., and nourished by empirical observations. The approach used in the Handbook of Enology is thus the same. It aims to provide practitioners, winemakers, technicians and enology students with foundational knowledge and the most recent research results. This knowledge can be used to contribute to a better definition of the quality of grapes and wine, a greater understanding of chemical and microbiological parameters, with the aim of ensuring satisfactory fermentations and predicting the evolution of wines, and better mastery of wine stabilization processes. As a result, the purpose of this publication is to guide readers in their thought processes with a view to preserving and optimizing the identity and taste of wine and its aging potential. This third English edition of The Handbook of Enology, is an enhanced translation from the 7th French 2017 edition, and is published as a two-volume set describing aspects of winemaking using a detailed, scientific approach. The authors, who are highly-respected enologists, examine winemaking processes, theorizing what constitutes a perfect technique and the proper combination of components necessary to produce a quality vintage. They also illustrate methodologies of common problems, revealing the mechanism behind the disorder, thus enabling a diagnosis and solution. Volume 2: The Chemistry of Wine and Stabilization and Treatments looks at the wine itself in two parts. Part One analyzes the chemical makeup of wine, including organic acids, alcoholic, volatile and phenolic compounds, carbohydrates, and aromas. Part Two describes the procedures necessary to achieve a perfect wine: the clarification processes of fining, filtering and centrifuging, stabilization, and aging. Coverage includes: Wine chemistry; Organic acids; Alcohols and other volatile products; Carbohydrates; Dry extract and mineral matter; Nitrogen substances; Phenolic compounds; The aroma of grape varieties; The chemical nature, origin and consequences of the main organoleptic defects; Stabilization and treatment of wines; The chemical nature, origin and consequences of the main organoleptic defects; The concept of clarity and colloidal phenomena; Clarification and stabilization treatments; Clarification of wines by filtration and centrifugation; The stabilization of wines by physical processes; The aging of wines in vats and in barrels and aging phenomena.

Book excerpt: Grapes (Vitis spp.) are economically the most important fruit species in the world. Most cultivated vines belong to the European type (Vitis vinefera), the American bunch type (V. labrusca and its derivatives) or Muscadine type (V. rotundifolia). Grapes contain many of the most valuable elements necessary for life. In addition, it is known to have commendable medicinal qualities/properties, attributed mainly to polyphenols. They are famous as antioxidants, hormones, constituents of essential oils, natural neurotransmitters, and as having many other biological activities. Their antioxidant ability is known to confer many health benefits such as reducing the risk of cardiovascular disease and cancer. They also provide antimicrobial activity for the plants own defense against invading pathogens. The diversity of structure and activity of phenolic compounds has resulted in a multiplicity of research areas such as chemistry, biotechnology, ecology, physiology, nutrition, medicine, and cosmetics. The understanding of grape and wine phenolics is an increasingly important requirement for managing wine styles efficiently and an important way to enhance their healthy benefit effects. The aim of this book is to describe grape production, its phenolic composition and the potential biomedical effects which are currently being researched. The areas of most interest at present and the subjects in which this interest is likely to continue or to increase in the following years have been selected. The book comprises 19 chapters, each written by authorities in the field with 59 contributing authors in total. Chapters are well referenced with regard to previous work, have appropriate chapter introductory sections accommodating non-specialists, students and experts in the field, and most end with a summary of conclusions and, in some cases, recommendations for future work or new standards, protocols or procedures.

Available in PDF, EPUB and Kindle. Book excerpt: Bioactive compounds in food, known for their positive health effects, can be lost during handling after harvest, processing and storage. While most foods are exposed to processing to increase shelf life and edibility and to ensure microbial safety, conventional processing methods may have disadvantages, such as decreasing the nutritional quality of foods, long processing times, high temperature and high energy uses. For these reasons, novel non-thermal food processing technologies (including HPP, ultrasound) and novel thermal food processing technologies (including microwave/Ohmic heating) have become widespread. This book provides a critical evaluation of the effects of conventional, novel non-thermal, and thermal food processing techniques on the retention and bioaccessibility of bioactive compounds in food materials. Within these three categories, many different processing methods are included: fermentation/germination, drying, extrusion, and modified atmosphere packaging, as well as novel technologies, such as microwave heating, ultrasound, high pressure processing, ozonation, and membrane separation processes.

This has resulted in a gradual shift from animal-derived to plant-based meals. Functional foods have turned into one of the rapidly expanding areas of the food industry due to the increasing awareness of consumers working to prevent lethal diseases like cancer, diabetes mellitus and cardiovascular disease. Functional foods are seen as the food or food components that manifest efficiency in protecting from diseases and attaining a healthier lifestyle by administering additional benefits on human physiology and metabolic functions apart from basic nutritional requirements of the body. Cereals hold a prominent place in this new market. Cereals and cereal foods are important energy sources and many phytochemicals such as dietary fiber, resistant starch, vitamins, minerals, lignans, phytic acid and phenolic compounds that provide a variety of health benefits. Eating functional cereal foods is an easy method to increase nutrients associated with whole grains without changing eating habits. Functional Cereals and Cereal Foods: Properties, Functionality and Applications comprehensively covers the Chemistry and nutritional composition of functional cereals components, their functionality and therapeutic significance, current innovations and functional approaches in improving attributes and biofortification and quality improvement of cereal products.

Available in PDF, EPUB and Kindle. Book excerpt: Processing and Impact on Antioxidants in Beverages presents information key to understanding how antioxidants change during production of beverages, how production options can be used to enhance antioxidant benefit, and how to determine the production process that will result in the optimum antioxidant benefit while retaining consumer acceptability. In the food industry, antioxidants are added to preserve the shelf life of foods and to prevent off-flavors from developing. These production-added components also contribute to the overall availability of essential nutrients for intake. Moreover, some production processes reduce the amount of naturally occurring antioxidants. Thus, in terms of food science, it is important to understand not only the physiological importance of antioxidants, but what they are, how much are in the different food ingredients, and how they are damaged or enhanced through the processing and packaging phases. This book specifically addresses the composition and characterization of antioxidants in coffee, green tea, soft drinks, beer, and wine. Processing techniques considered here include fermentation and aging, high-pressure homogenization, enzymatic debittering, and more. Lastly, the book considers several selective antioxidant assays, such as Oxygen Radical Absorbance Capacity (ORAC) and Trolox Equivalent Antioxidant Capacity (TEAC) assays. - Provides insights into processing options for enhanced antioxidant bioavailability - Presents correlation potentials for increased total antioxidant capacity - Includes methods for the in situ or in-line monitoring of antioxidants to reduce industrial loss of antioxidants in beverages - Proposes processing of concentrated fractions of antioxidants that can be added to foods
