Aroma analysis indicated treatments accounted for an average of 59% of the variance in aroma for all three seasons (Figure 1). GDC wines were distinguished by overall aroma intensity, and fruity, sweet vanilla aromas. Aroma descriptors appeared to cluster around growing season. For example, wines produced in the cool, wet, 2003 vintage with limited fruit Brix were generally characterized by vegetative aromas, while those produced in the drier and warmer 2004 vintage had higher fruit and overall aroma intensity.

GLOSSARY of Wine-Tasting Terminology
All wines contain acetic acid - (ie: vinegar). Normally the amount is insignificant and may even enhance flavour. At a little less than 0.10% content, the flavour becomes noticable and the wine is termed acetic. Above 0.10% content is considered a strong fault. A related substance, ethyl acetate, contributes the smell associated with acetic acid content.

"Ascescence" is the term used to mark the presence of acetic acid and ethyl acetate. Detected by sweet and sour, sometimes vinegary smell and taste along...

Evidence Based Nutrition Principles

...Evidence Based Nutrition Principles For Diabetes Mellitus Management Evidence Based Nutrition for Diabetes Mellitus Management Dietary management in people with diabetes mellitus (DM) and those at risk for DM requires greater attention especially given current trends that suggest 1 in 3 people will have diabetes by 2050 (Benson et. Al., 2011). Type 2 diabetes accounts for about 90-95% of diagnosed cases, and the underlying metabolic problem that insinuates this disease is obesity (Vojta, De Sa, & Prospect, 2012). Obesity is accountable for the increase in insulin resistance, metabolic syndrome, and type 2 DM across all ages (Reisin, 2010). If left untreated and unmanaged, DM can potentiate nerve and blood vessel damage with eventual blindness, kidney damage, limb amputations, and cardiovascular complications leading to stroke and heart attack (2012). Medical nutrition therapy (MNT) can assist people to combat obesity, the major catalyst of this disease, in order to prevent diabetes, manage existing diabetes, and slow the onset of diabetes-related complications (Morris & Wylie, 2010). Since a major component of MNT is dietary management, extensive research has been conducted on what dietary guidelines assist in preventing the onset of DM 2 and in controlling existing DM 1 and 2. Before the discovery of insulin in 1922, low-carbohydrate diets were used as a sole means of controlling DM (Spritzler, 2012). Today, this method of control is still implemented; however...

Total calorie intake for this meal is 635. The meal contains: • Saturated fat which is a fatty acid that has no carbons bonded together with a double bond. • Cholesterol is a form of lipid that our bodies can make independently. • Sodium is an element that the body needs to work properly. The body uses sodium to control blood pressure and blood volume. Sodium is also needed for your muscles and nerves to work properly. Salt contains sodium. • Carbohydrates are the primary fuel source for our bodies, particularly for our brain and for physical exercise. They are composed of chains of carbon, hydrogen and oxygen. • Dietary fiber is the nondigestible carbohydrate parts of plants that form the support structures of leaves, stems and seeds.

Mediteranean Diet

...legumes; a moderate consumption of fish, shellfish, poultry, eggs, dairy and olive oil; and a very limited consumption of red meat, processed foods, sugary foods and saturated fats. Adequate consumption of water is necessary and wine can be consumed in moderation (Del Chierico, Vernocchi, Dallapiccola, Putignani). In recent years there has been significant scientific evidence suggesting that closely following the Mediterranean diet provides adequate nutrient intake and can help decrease the risk of non-communicable, chronic disease for which multiple factors including diet and lifestyle can be attributed (Egger). In order to decrease the risk for cardiovascular disease, type II diabetes, some cancers, increase overall well-being, and reduce the monetary burden of these chronic diseases, Americans should consider adopting the Mediterranean diet. Cardiovascular disease is the leading cause of death in the United States, with an estimated 610,000 people dying because of it each year. Poor diet and obesity are two of the leading risk factors associated with this disease (“Heart Disease Facts”). Because cardiovascular disease is considered a low-grade inflammatory disease, there has been great interest in the anti-inflammatory effects associated with the Mediterranean diet (Sofi, Abbate, Gensini, Casini). Olive oil, which is high in oleic acid, monounsaturated fatty acids and polyphenols, is the main source of fat intake on the Mediterranean diet and is shown to have......

...Food & Wine “Food without wine is a corpse; wine without food is a ghost; united and well matched they are as body and soul, living partners.”-Andre Simon (1877-1970) Simply true, Food & wine are truly inseparable partners. Ancient history tells us that initially wine was used as a substitute to water with food. But as time passed and wine became associated with social evil rather than necessity, wine industry re launched it as a meal component rather than an alcoholic beverage. As of now, many wine bottle labels come with food pairing tips and restaurants have special staff who take all pains to ensure that the flavors of food and wine are in perfect harmony. And if you have tried and not liked wine, bad paring could be a reason. Though pairing of food & wine may vary with personal preferences but there are still some basics to consider. Here are some basic principles for making a perfect pair: * WEIGHT & TEXTURE- weight or body of wine means the alcohol content, the lesser the lighter. Paring light wine with heavy recipes or heavy wine with light meal , would make the taste competing rather than complimenting each dry Riesling paired with shammi kebab * ACIDITY- Wines could be high or low on acidity level , depending on type of parent grapes. High on acid wines complement well with fatty foods. such as Sauvignon Blancs or Barberas go well with Pasta with Tomato Sauce. * FLAVOR INTENSITY – Paring the wine with the most dominant......

Why a Western Diet Is Unhealthy and What People Should Eat to Be Healthy

...disadvantages that a Western diet can cause. First and foremost is that the consumption of excessive calories often leads to obesity Agarwal (2008) reports that the USA has the highest daily consumption of calories per capita in the world, with 3770 calories consumed per person per day. According to Kemp, Paul and Segal (2001-10), a western diet contains a lot of sugar, which of course means more calories. To illustrate, 10 teaspoons of sugar are found in one cup of concentrated fruit juice. The typical diet in the USA has lead to sixty-five percent of people twenty years and older being obese, and this number is increasing (Agarwal 2008). Secondly, a typical Western diet is often high in unhealthy fats. Many standard Western foods such as red meat and dairy products contain a large amount of saturated fats. On top of this, processed foods such as margarines, candy and cookies are high in trans-fats (Kemp, Paul and Segal 2001-10). Moreover, Agarwal (2008) affirms that consuming large amounts of unhealthy fats is strongly linked with heart disease. To illustrate, 38.5% of Americans deaths are caused by cardiovascular disease with a further 65 million people living with this disease. According to a major scientific study called the Seven Countries Study, out of 6000 recorded deaths,...

The Liver

...toxicity on the structure and function of the liver. The liver is the largest internal organ and the largest gland in the body. Glands produce hormones that other parts of the body use to function. The liver is divided into two major sections; the right side is bigger while the left is smaller. Sixty percent of the liver is made up of liver cells called hepatocytes; these cells take in nutrients, destroy and remove harmful substances from the blood. The liver is important for survival, it has many functions, and according to the British Liver Trust (2007) it has over five hundred functions. Here is a brief summary of some of the functions of the liver. It processes digested food from the intestine, it controls the levels of fats, amino acids and glucose in the blood, fights infections, produces bile, breaks down food and turns it into energy as well as produces quick energy. It produces, breaks down and controls most hormones in the body, it also makes enzymes and proteins, and these are responsible for most chemical reactions in the body, British Liver Trust (2007). There are many conditions that can affect the functions of the liver. One of these is alcohol abuse. Alcohol is developed from the fermentation of sugar by yeast. It is a drug. The liver cannot store alcohol so it breaks down the alcohol into water, carbon dioxide and fat, then processes about ninety percent of the alcohol and removes around five percent from the body through urine and sweat, Paton (2005)......

Magic Box Report

...Advanced Culinary P&P1 | Magic Box and Menu Design | Paper 215014 | Lyle Robertson 1111431 4/30/2012 | Contents Introduction 3 Summary 3 Menu 4 Menu Overview 5 Ingredients list and Usage 9 References & Word Count: 11 Introduction The essence of a Magic box is to show culinary skills and creativity in producing a dish that has complimentary and balanced flavours. This dish is created from a list of ingredients with emphasis on texture, colour, taste, balance, nutrition and presentation. With this criteria in mind I set out to produce two menu items, one entree and one main, that utilised as many ingredients as possible from the list provided and that encompassed the above elements. Starting with the listed proteins as the central components to each dish, I then took into consideration the season and how best I could utilise my strengths. Inspired by the composition of a dish from La Chapelle, London I began with my entree and developed a concept using the lighter of the two proteins the John Dory and Scampi. To create my main dish, I explored the best cooking method suited for the cut of meat available, the beef cheeks. I then made the decision that beef cheeks are best braised as this enhances the flavour of the meat and ensures it is tender. With my cooking technique selected I then utilised the list of ingredients available to build and create flavours that would compliment this. This report will set out to provide further......

Economics blood * Transferrin – involved in iron transport in blood * Immunoglobulins – involved in immune system responses Fibrous proteins is a protein with an elongated shape. Fibrous proteins provide structural support for cells and tissues. There are special types of helices present in two fibrous proteins α-keratin and collagen. These proteins form long fibers that serve a structural role in the human body. Fibrous proteins are distinguished from globular proteins by their filamentous, elongated form. Also, fibrous proteins have low solubility in water compared with high solubility in water of globular proteins. Most of them play structural roles in animal cells and tissues, holding things together. Fibrous proteins have amino acid sequences that favour a particular kind of secondary structure which, in turn, confer particular mechanical properties on the proteins. Examples: * Keratins – found in wool, feathers, hooves, silk, and fingernails * Collagens – found in tendons, bone, and other connective tissue * Elastins – found in blood vessels and ligaments * Myosins – found in muscle tissue * Fibrin – found in blood clots Enzymes * Enzymes serve a wide variety of functions inside living organisms.

India's Wine Business

...India’s wine business ------------------------------------------------- Wine regions[edit] Vineyards in India range from the more temperate climate of the northwestern state of Punjab down to the southern state of Tamil Nadu. Some of India's larger wine producing areas are located in Maharashtra, Karnataka near Bangalore and Telangana nearHyderabad. Within the Maharashtra region, vineyards are found on the Deccan Plateau and around Baramati, Nashik, Pune, Sangliand Solapur. The high heat and humidity of the far eastern half of the country limits viticultural activity.[2] While wine consumption in most of the countries is increasing at a rate of 4-5% a year, in India the wine consumption is increasing at rates of 25-30% a year. A study of the department of chemical engineering at the University of Vigo (Spain) suggests that "companies must invest in new technologies to reduce the impact of agro-industrial waste into the environment and establish new processes that provide additional sources of revenue" Of wine in the cellar are different wastes: liquid (effluent), organic (marc, lees, stalks) solids, and other solids (packaging waste, household type, etc.). Of these, those used are of the second type.The average composition of the grapes that go into a winery is 83% pulp and the remaining 17% composed of grape skins, pips and scrapes, are discarded.
