Storage factory spreads and mixtures melted vegetable-creamy and vegetable-fat

Pie crust is possibly one of the worlds most difficult things to make. Thanks plants! Now I will eat you… muhahah. Ehem, getting back to pie crust: every now and then over the last few years I have tried to make a simple vegan pie crust recipe. It would fall apart, look terrible, and become wooden when cooked. Not at all the pie crust of my dreams… or even my nightmares, just completely un-rememberable.

Specific oils and shortenings for food manufacturers

Manufacturers use the process of hydrogenation to create trans fats in order to increase the shelf life of baked and fried foods.

Ingestion of trans fats is associated with an increased risk of cardiovascular disease. A groundswell of public sentiment is causing regulatory bodies to ban the use of trans fats in foods. Alternatives to trans fats are needed now in order to preserve the freshness and provide an appealing texture of many packaged foods. As trans fats become phased out, there are eight types of approaches currently being developed to substitute for these fats as ingredients for baked and fried foods: 1 modified hydrogenation, 2 genetically modified seeds, 3 interesterification, 4 fractionation and blending, 5 butter and animal fat, 6 natural saturated oils, 7 natural unsaturated oils, and 8 fat substitutes.

These alternatives to trans fats will require close scrutiny to ascertain whether they will also turn out to be linked with cardiovascular disease. Vegetable oils contain a high concentration of unsaturated fatty acids. These fats are prone to oxidation, which produces rancidity. Trans fatty acids or trans fats are produced when food manufacturers add hydrogen to unsaturated vegetable oils to saturate or partially saturate their unsaturated bonds for use in cooking, frying, or baking.

This hydrogenation process increases the stability, resistance to oxidation, and shelf life of vegetable oils. In addition, hydrogenation raises the melting point of unsaturated vegetable oils, which are liquid at room temperature. This process hardens the oils and converts them into solid or semisolid fats. A solid texture is necessary for the manufacture of shortenings and margarine.

Generally, the higher the saturated fatty acid content, the harder a fat will be at room temperature. The main component of fats and oils is triglycerides, which contain one glycerol molecule and three fatty acid molecules.

When these substances are solid at room temperature, then they are called fats, and when they are liquid at room temperature, then they are called oils. This article uses the terms fats and oils interchangeably.

The ingestion of trans fats is associated with heart disease and, for that reason, the use of these substances as food additives is increasingly coming under attack. Trans fats are being removed from many widely sold foods and are becoming banned from use in restaurants in many communities. These oils have served a function in the food manufacturing and preparation industries and will need to be replaced by other types of oils.

This article reviews the structure and function of trans fats and discusses their potential replacement. The major types of fats in the diet are saturated, polyunsaturated, monounsaturated, and trans fats.

While unsaturated fats monounsaturated and polyunsaturated are beneficial when consumed in moderation, saturated and trans fats may not be. Intervention studies have demonstrated that trans fats raise low-density lipoprotein LDL cholesterol levels, lower high-density lipoprotein HDL cholesterol levels, 1 and raise lipoprotein a levels.

All these effects on risk factors with trans fat ingestion are associated with an increased risk of coronary artery disease. An additional health risk from ingestion of trans fats is decreased fertility. Saturated fatty acids contain the maximum number of hydrogen atoms that the chain of carbon atoms can hold Figure 1. Saturated fats are usually solid at room temperature. They are inert and do not combine readily with oxygen to become rancid. Saturated fatty acids are found in animal fats and in coconut oil, palm oil, and cocoa butter.

Monounsaturated fatty acids contain a single unsaturated or double bond. They lack two hydrogen atoms. Monounsaturated oils usually are liquid at room temperature but solidify at refrigerator temperatures. Monounsaturated fatty acids can help decrease LDL cholesterol when substituted for saturated fats in the diet.

Monounsaturated fatty acids are found in canola oil, olive oil, peanut oil, nuts, and avocados. Polyunsaturated fatty acids contain more than one unsaturated or double bond and are liquid both at room temperature and in the refrigerator. They may combine with ambient oxygen and become rancid. Polyunsaturated fatty acids can help lower LDL cholesterol when substituted for saturated fats in the diet.

These fatty acids are found in safflower oil, corn oil, sunflower oil, soybean oil, fatty fish such as salmon, mackerel, smelt, herring, and trout , walnuts, and seeds. Trans fats are a type of fat that is formed when liquid oils are converted into solid fats such as shortening and hard margarine through partial hydrogenation of their unsaturated fatty acids.

In this process hydrogen is added to polyunsaturated oil to fill some but not all of the unsaturated bonds. Trans fats are found in foods containing partially hydrogenated oils or cooked in such oils. In trans fats the two hydrogen atoms are on opposite sides of an unsaturated double bond, as opposed to cis fats in which the two hydrogen atoms are on the same side of the double bond. Compared to cis fatty acids, trans fatty acids molecules can pack closer together and are less fluid.

Thus, trans fats, compared to cis fats, have a higher melting point. This property results in trans fats assuming a solid state rather than a liquid state at room temperature.

Trans fats are incorporated into endothelial cell membranes and thus can alter cellular and macromolecular components acting at the interface of the blood vessel wall. These alterations could result in changes in the antihemostatic properties, altered vascular tone, hyperadhesiveness to blood leukocytes, and increased cytokine and growth factor production, all of which are characteristics of endothelial dysfunction.

Unsaturated carbon atoms, each with one hydrogen atom, joined by a double bond in the cis configuration. Unsaturated carbon atoms, each with one hydrogen atom, joined by a double bond in the trans configuration. During hydrogenation of monounsaturated and polyunsaturated fatty acids in vegetable and fish oils, far more trans than cis double bonds are formed. Furthermore, during hydrogenation of unsaturated fatty acids, cis bonds may be converted into trans bonds.

Almost all edible fats from plants contain unsaturated fatty acids in the cis conformation. Trans fats are found naturally in low levels in meat and dairy products because of bacterial hydrogenation of cis -unsaturated fatty acids in the stomachs of ruminant animals.

However, the major source of trans fats in the diet is foods containing industrially modified and partially hydrogenated vegetable oils. As food ingredients, partially hydrogenated oils, compared to naturally unsaturated oils, decrease food spoilage. As a frying medium, however, unsaturated oils tend to become foamy, smoky, or dark colored after prolonged use.

Restaurants may prefer to fry with partially or fully saturated fats because these fats need not be changed as frequently. Saturated oils in these foods will contribute to a desirably soft texture, volume, aeration, and feel of such foods at room temperature. Most of the trans fat in a typical American diet comes from commercially fried and baked foods made with vegetable shortening, hard margarines, and oils containing partially hydrogenated oils and fats.

According to U. The main contributors to total trans fat intake include margarine Animal products supply the remaining As of January 1, , the FDA has required manufacturers of conventional foods and some dietary supplements to list trans fat on their nutrition labels.

Manufacturers of dietary supplements e. In the U. The FDA calculated that the beneficial lipid effect would result in a gain of — discounted life years annually in the United States.

The FDA further estimated, by including avoidance of both fatal and nonfatal events, that this ruling will provide an annual savings to the U. Tiburon, California became America's first city to ban trans fats from restaurants in New York City became America's first major metropolis to ban trans fats from restaurants in December Restaurants in that city will be barred from using most frying oils containing artificial trans fats by July and will have to eliminate artificial trans fats from all of their foods by July In Denmark became the first country to introduce laws limiting the amount of trans fat in processed foods.

The measure would not apply to packaged food sold in either grocery stores or restaurants. If this bill becomes law, then California would be the first state in the United States to ban the use of trans fats. Several factors have limited the introduction of alternatives to trans fats into the marketplace: 1 performance, 2 availability, 3 economics, and 4 safety.

Replacement products for trans fats must be able to provide at least the same functional characteristics of the materials they replace. Partial hydrogenation allows creation of many engineered saturated or partially saturated oils with specific characteristics for use by the food industry. No alternate method for creating a wide range of fats for frying and storage of baked products has thus far been developed.

The use of trans fat alternatives in major consumer products, such as fast foods, requires a large supply. New candidate oil products are not yet commercially available on a significant scale because of a lack of adequate acreage for growing new seed crops. These oil products could become widely available within a few years, however, if the food industry is committed to their use.

The increased costs of developing and producing trans fat alternatives will be passed on to consumers of foods containing these products. The safety of any alternative to trans fats must be studied so that consumers are not simply ingesting an alternate form of saturated fat that will be just as dangerous as natural saturated fats or as trans fats. The food industry is in the process of searching for alternative oils to trans fats that can provide good flavor, deliver good performance, and be purchased at a good price.

Vegetable oils have only limited applications in food products when they are used in their native form. They must therefore be modified chemically, physically, or genetically in order to change their properties.

When products containing partially hydrogenated fats or oils are reformulated to lower the trans fat content, functionality may require the reformulated products to have more saturated fat than the original product.

Partially hydrogenated oils were introduced into the U. On January 24, , Crisco was reformulated to eliminate trans fats by J. Smucker Co. This reformulation reflects a widespread trend in the food industry to remove hydrogenated vegetable oils from cooking spreads 13 such as shortening which is a pure fat product that is solid at room temperature often because of a high concentration of hydrogenated trans fats and margarine which is a water-in-oil emulsion made from vegetable or animal oils that may contain high concentrations of hydrogenated trans fats as hardening agents.

Butter is not affected by this trend because this spread is made from butterfat, an ingredient in cream, and contains mostly naturally saturated fat and no hydrogenated fats. As trans fats become phased out, there are currently eight types of approaches being developed to substitute for these fats as ingredients for baked and fried foods.

These approaches are listed next. Full hydrogenation of vegetable oils would produce exclusively saturated fatty acids that are too waxy and solid to use in food production. Consequently, the partial hydrogenation process used by the industry is not intended to eliminate all the double bonds.

Partially hydrogenated oils increase the shelf life and flavor stability of foods, as well as modify some of the saturated fatty acids that can oxidize and become rancid. Processes under development can generate hydrogenated oils containing less than half the level of trans fat produced under traditional hydrogenation conditions. The standard hydrogenization process can be modified by altering the type of catalyst, the time of the reaction, or the temperature and pressure of the process.

Food Industry. Food fat provides taste, consistency, and helps us feel full. Fat is a major source of energy for the body, and aids in the absorption of lipid soluble substances including vitamins A, D, E, and K. Dietary fat is essential for normal growth, development, and maintenance, and serves a number of important functions.

Fats occur naturally in food and play a significant role in human nutrition.

Manufacturers use the process of hydrogenation to create trans fats in order to increase the shelf life of baked and fried foods. Ingestion of trans fats is associated with an increased risk of cardiovascular disease. A groundswell of public sentiment is causing regulatory bodies to ban the use of trans fats in foods.

Fats and oils are the most abundant lipids in nature. They provide energy for living organisms, insulate body organs, and transport fat-soluble vitamins through the blood. Fats and oils are called triglycerides or triacylcylgerols because they are esters composed of three fatty acid units joined to glycerol , a trihydroxy alcohol:. If all three OH groups on the glycerol molecule are esterified with the same fatty acid, the resulting ester is called a simple triglyceride. Although simple triglycerides have been synthesized in the laboratory, they rarely occur in nature.

Common Baking Mistakes

First we have this mistake: You make substitutions to lighten your favorite full-fat recipes. The Fix: Substitutions are a particular temptation, and challenge, with healthy cooking. When it comes to baking, this is as much science as art. We'll get calls from readers about cakes turning out too dense or too gummy. Best practice: Follow the recipe, period. The best advice: Always preheat to avoid having any surprises emerge from your oven. THE FIX: When measuring sticky ingredients, such as honey, molasses, or syrup, avoid the mess by coating the measuring cup or spoon with cooking spray before you measure.

Jan 3, - Hyvonen et al. investigated the effects of dairy and vegetable fats (0% to 18%) on the perception of strawberry flavour release and melting of ice cream. During storage, ice and lactose crystals grow and undergo recrystallisation. During dynamic freezing, where the ice cream mix is frozen in an ice.

Butter is made from the butterfat of milk, whereas modern margarine is made mainly of refined vegetable oil and water. In some places in the United States, it is colloquially referred to as oleo , short for oleomargarine. Due to its versatility, margarine can be used as an ingredient in other food products, such as pastries, doughnuts, cakes and cookies. In , the German structural chemist Wilhelm Heinrich Heintz analyzed margaric acid as simply a combination of stearic acid and the previously unknown palmitic acid.
