FOR EWO RD 0.1 This Indian Standard was adopted by the Indian Standards Institution on 16 September 1966, after the draft finalized by the Dairy Industry Sectional Committee had been approved by the Agricultural and Food Products Division Council. 0.2 Ghee (milk-fat, butterfat, butter-oil), is the most important dairy product which enters inter-state trade. Due to variation in its composition from region to region and season to season, depending on the type of animal and the food given, the establishment of its purity often involves elaborate analysis, as well as tests for its keeping quality. The present standard describes the methods of sampling and quality control generally needed for such analysis and facilitates the interpretation of results. 0.3 In the formulation of this standard, considerable assistance has been derived from the following publications: FIL-IDF 6 Acidity of butterfat. International Dairy Federation. FIL-IDF 7 Refractive index. International Dairy Federation. FIL-IDF 8 Iodine value. International Dairy Federation.

  • Olive Oil Jars Left Behind By
    live oil jars left behind by the ancient Greeks are testament to our centuries- old use of cooking oil. Along with salt and pepper, oil Oremains one of the most important and versatile tools in your kitchen. It keeps food from sticking to pans, adds flavor and moisture, and conducts the heat that turns a humble stick of potato into a glorious french fry. Like butter and other fats, cooking oil also acts as a powerful solvent, unleashing fat-soluble nutrients and flavor compounds in everything from tomatoes and onions to spices and herbs. It’s why so many strike recipes begin with heating garlic in oil rather than, say, simmering it in water. The ancient Greeks didn’t tap many cooking oils. (Let’s see: olive oil, olive oil, or—ooh, this is exciting!—how about olive oil?) But you certainly can. From canola to safflower to grapeseed to walnut, each oil has its own unique flavor (or lack thereof), aroma, and optimal cooking temperature.

  • Cooking Oil Facts
    Cooking Oil Facts As you enter a department store, you behold an array of cooking oils sporting all types of jargon on the packaging -- saturated fats, unsaturated fats, refined, filtered, ricebran oil, vanaspati, etc. Confused already? With so much variety and so many brands flooding the market today, buying the right cooking oil can prove a tough task. Different oils fill different needs - for health, taste and cooking. For good health, our bodies need a variety of healthy fats that are found naturally in different oils. When cooking, it's essential to know which oils are best for baking, sautéing and frying and which are healthiest used raw. Why have Oil (fats)? Contrary to popular belief, fat is actually a valuable part of one's diet, allowing people to absorb nutrients that require fat in order to metabolize in the body. Natural fats contain varying ratios of three types of fats: saturated, monounsaturated and polyunsaturated. • Saturated fats are hard at room temperature. They're stable, resist oxidation, and are found primarily in meat, dairy, palm and coconut oil. • Polyunsaturated fats are liquid at room temperature and the least stable. They oxidize easily and are found in seafood corn, safflower, soybean, and sunflower oils. • Monounsaturated fats are more stable than polyunsaturated fats. They're found in canola, nut and olive oils. It is recommended to limit saturated fats in the diet due to their association with cardiovascular disease. Also, you should try to rely more on monounsaturated than polyunsaturated fats. What are the varieties of Oil available in the market? Choosing which oil should be used in cooking is a big issue and concern for many people because of the fat and cholesterol contents of cooking oil.

  • Nutrition Handout N09: What Are the Types of Fat?
    N09 What Are the Types of Fat? Most foods contain several different kinds of fat. Some are better for your health than others. It is wise to choose healthier types of fat, and enjoy them in moderation. Keep in mind that even healthier fats contain calories and should be used sparingly for weight management. Here is some information about healthy and harmful dietary fats. The four major types of fats are: • Monounsaturated fats • Polyunsaturated fats • Saturated fats • Trans fats Monounsaturated and polyunsaturated fats are known as “healthy fats” because they are good for your heart, cholesterol levels, and overall health. These fats tend to be “liquid” at room temperature. Consider beneficial polyunsaturated fats containing Omega-3 fatty acids found in fatty fish, flaxseed, and walnuts. www.move.va.gov Nutrition Handouts • N09 Version 5.0 Page 1 of 3 Healthy Dietary Fats Monounsaturated Fat Polyunsaturated Fat Olive oil Soybean oil Canola oil Corn oil Sunflower oil Safflower oil Peanut oil Walnuts Olives Sunflower, sesame, and pumpkin seeds; flaxseed Nuts (almonds, peanuts, hazelnuts, Fatty fish (salmon, tuna, mackerel, herring, macadamia nuts, pecans, cashews) trout, anchovies, sardines, and eel) Avocados Soymilk Peanut butter Tofu Tips for increasing healthy fats in your diet: • Cook with olive oil. • Plan snacks of nuts or olives. • Eat more avocados. • Dress your own salads instead of using commercial dressings. Saturated fats and trans fats are known as the “harmful fats.” They increase your risk of disease and elevate cholesterol. Saturated fats tend to be solid at room temperature, but they are also found in liquid tropical oils (palm and coconut).

We examined the `overnight second-meal effect' of bedtime supplements containing `rapid' or `slow' CHOs. Design: Randomized cross-over study with three test-periods, each consisting of two days on a standardized diet, followed by a breakfast tolerance test on the third morning. Setting: The Lundberg Laboratory for Diabetes Research, Sahlgrenska University Hospital, GoÈteborg, Sweden. Subjects: Sixteen patients with type 2 diabetes on oral agents and=or diet. Interventions: Two different bedtime (22.00 h) CHO supplements (0.46 g available CHO=kg body weight) were compared to a starch-free placebo (`normal' food regimen). The CHOs were provided as uncooked cornstarch (slow-release CHOs) or white bread (rapid CHOs). Results: On the mornings after different bedtime meals we found similar fasting glucose, insulin, free fatty acid and lactate levels. However, the glycaemic response after breakfast was 21% less after uncooked cornstarch compared to placebo ingestion at bedtime (406Æ 46 vs 511Æ 61 mmol min 171, P < 0.01).

    nutrients Article Butter, Margarine, Vegetable Oils, and Olive Oil in the Average Polish Diet Hanna Górska-Warsewicz * , Krystyna Rejman , Wacław Laskowski and Maksymilian Czeczotko Department of Food Market and Consumer Research, Institute of Human Nutrition Sciences, Warsaw University of Life Sciences, 02-787 Warsaw, Poland; [email protected] (K.R.); [email protected] (W.L.); [email protected] (M.C.) * Correspondence: [email protected]; Tel.: +48-22-5937144 Received: 13 November 2019; Accepted: 27 November 2019; Published: 3 December 2019 Abstract: The main aim of this study was to identify the sources of energy and 25 nutrients in fats and oils in the average Polish diet. We analyzed energy, total fat, saturated fatty acids (SFAs), monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), cholesterol, protein, carbohydrates, nine minerals, and nine vitamins. We included five sub-groups: butter, vegetable oils, margarine and other hydrogenated vegetable fats, olive oil, and other animal fats. The basis for our analysis was data from the 2016 household budget survey, conducted on a representative sample of the Polish population (36,886 households, n = 99,230). We used the cluster analysis to assess the impact of socio-demographic and economic factors on the volume of fats and oil consumption and on the share of particular products in the supply of energy and nutrients. Our findings indicated that fats and oils contributed 32.9% of the total fat supply, which placed these products in first position among main food groups. Meat and its products ranked second (30.8%) in the total fat supply, while milk and dairy products, including cream (13.4%), were the third food group.
