Type of foods high in trans fats

Why does your favorite potatoes and fried chicken from restaurant feels more delicous and crispy than you cook by yourself at home? The answer probably is trans fats. It contribute to foods texture, better taste and give you high energy, but it is not good for heart health. It can also raise cholesterol levels, exacerbating inflammation, reduce levels of good cholesterol that prevent heart disease and cancer risk. So what is type of foods high in trans fats ?

Instant cake mix
It is certainly easier to make cookies with instant cake mix. But it's better if you make the cake from begining to the finished cake to ensure you have served the healthy kind of foods for your family.
French fries
Who does not like french fries. Its delicious taste that will make anyone want to eat it more. However, unfortunately the fries contain trans fats which come from the frying.
Fried foods
Just like french fries, you never really know what oil is used to fry it. And it should be avoided if you are not sure of the materials used. Then, frying with used oil or using the same oil for frying repeatedly may be also bad for your health.
Frozen cakes and pies
Baked products that you buy from stores, especially those that can be stored for a long time, may contain this kind of material. Frozen cakes and pies are often a source of type of foods high in trans fats you should avoid.
Donuts
Without that ingredient, donuts will be very oily. In order to create softer texture, snacks such as cake, donuts, and cookies using it.
Pop corn
Popcorn sold in movie theaters may contain these ingredients. To keep the taste, the use of margarine may be substituted with butter.
Coffee creamer
Creams contained in many snacks and beverages, such as coffee, are trans fats.
Biscuits (crackers)
Most crackers use this product, which can be replaced with soy or canola oil to make it safe.
Foods and Drug Administration (FDA) announced that they will restrict or prohibit trans fats significantly from foods in the U.S. This agency decided that it was not safe for human health, and should not be in the foods we eat. In 1999, the FDA first proposed that manufacturers should disclose the content of trans fats on nutrition labels, but it did not become a requirement until 2006. Many of the companies have gotten removed it from their products, and New York City even ban trans fats from restaurant foods in 2006. But, according to the FDA, there are type of foods high in trans fats, such as donuts, biscuits crackers, popcorn, frozen pizza, coffee creamer, frozen dough products as well as canned products. It is a real challenge for the industry and scientists.

Vegetable oils products, free of trans fats

Trans fats linked so far to cardiovascular disease, although on the other hand, contribute to food texture preferred by consumers. It can be formed, for example when some types of margarine (which is produced by the partial hydrogenation) are heated. Therefore, it needs to be reconsidered to develop products that are more friendly to health, and off course still maintain the sensory value. Actually increasing concern for health is a chance for the industry, particularly palm oil to produce vegetable oils products that are free of trans fats because it does not contain the types of fats.

Research conducted by Byung Hee Kim et al (2009) from the University of Georgia said that the interesterification mixture from vegetable oil of canola, palm stearin (PS), and palm kernel with a certain ratio produced margarine with the same quality as a commercial margarine. As for shortening, a mixture of PS and coconut oil (CnO) produced fats that can be used as an elastic shortening. Jeyarani et al. (2009) in a report published by the Journal of Food Chemistry stated that a mixture with a certain ratio of PS and CnO has a wider melting range, making it suitable to be used as a shortening.
Other alternatives of vegetable oils products that are free of trans fats is to develop Cocoa Butter Substitute (CBS). It can be produced from vegetable oils and fats by chemical means or fractionation and enzymatic processing. CBS manufacture technology from palm kernel oil (PKO) has been developed into a large industrial scale including fractionation and hydrogenation and its combination. But this technology in small-scale industries are not yet available. PO Research Center in Indonesia has resulted technology of full hydrogenation process for crude PKO and without producing trans fats under conditions of moderate temperature and high pressure. Magnification scale into 100 kg/batch needs to be done and the process conditions are optimized to support the use of PKO in small and medium scale industries. The process of hydrogenation use hydrogen to saturate the unsaturated fatty acids with the aid of a catalyst. Commonly used catalyst is the nickel. The fats products which contain no trans fats is important because of its low density increase lipoprotein (LDL) and lower high-density lipoprotein (HDL) thus becomes an important risk factor in coronary heart disease.

Trans fats in snack

World snack industries are growing quite rapidly. Innovation and high market demand is the key why the product is still evolving. In fact, this excessive consumption is often regarded as the cause of several health problems. For example, obesity, trans fats in snacks, acrylamide, and so on.
The substantial processing of trans fats solidify liquid oils (usually vegetable oil) with hydrogen gas in a process known as hydrogenation (ie, by adding hydrogen to them). This processing is performed to improve the oxidative stability so that the product is not susceptible to oxidation processes. This process is used to make margarine. Most of them are artificially synthesized through a chemical process that adds hydrogen to vegetable oil. In short words, it means changing liquid oils into solid fats.
The benefits of this hydrogenation are the cheap product with a longer period of storage and extending its shelf life and adding flavor savory meal. Trans fats in snacks can make delicious stuff, and french fries in fast food restaurants favored by many people. With this fat biscuits may last more than 1 year . Another feature of these ingredients is to make the food tasty textured or easily melted in the mouth, crispy, and generate flavor and aroma of savory and delicious. Children generally love this kind of snack.
They are formed through a process of partial hydrogenation and its existence becomes a very important issue in recent years. This is because of the presence of trans fatty acids can lead to increased levels of LDL cholesterol in the blood and the risk of heart disease. So it is understood if the USFDA requires to include the presence of these fatty acids in the label. However, in recent years many food manufacturers have taken steps to limit or eliminate trans fats in snacks. Several fast food restaurants, since a decade ago claimed to have stopped cooking fries using it. Many company websites claim that all kinds of fried foods have trans fats free. Even New York City in 2007 adopted regulations that prohibit partially hydrogenated vegetable oil spread in the restaurant.
Since 2005, food manufacturers have claimed to lower their amount in snacks to more than 73 %. Trans fats intake among U.S. consumers declined from 4.6 grams per day in 2003 to about 1 gram per day in 2012, according to FDA. Other countries also trying to reduce them in snacks are Brazil, Costa Rica, Denmark, the Netherlands, South Korea and the United States and has been proven effective over the past two decades, according to the WHO.

Fatty acid composition of soybean oil

Soybean is well known as the raw material for the production of traditional food in Indonesia, such as tempeh and tofu, while in the USA it is widely used to produce oil, because the fat content is quite high at 14-23%, and an average of 19%. Therefore, soybean oil has long been known as a frying medium which is commonly used in the United States and European countries. But in Asian countries, especially Southeast Asia, palm and coconut oil is more commonly used for frying because of the availability of its raw materials that is abundant in that region. The debate regarding the impact of the fatty acid content of the three types of frying medium on health is rising. Therefore, the fatty acid composition of soybean oil and the consequence should be understood first.
Oil content and composition in soybean are influenced by varieties, climate, and growing conditions. Crude fat content indicate the presence of triglycerides 90-95%, while the rest is phosphatides, free fatty acids, sterols, and tocopherols. Its oil content is relatively lower than other types of beans, but higher than the cereals. High protein levels lead to its common usage as protein source instead of oil sources in some countries.
Fatty acid composition of soybean oil is rich in essential fat (linoleat/omega-3 and linolenat/omega-6) that is needed by human body and is claimed to prevent atherosclerosis. In more detail, unsaturated fat content is about 85%, consisting of oleic (11-60%), linoleic (15-64%), linolenic (1-12), and arachidonat (1.5%), while its saturated fat is about 15%, consisting of palmitic (7-10%), stearic (2-5%), and others (<1 data-blogger-escaped-font="">.2%). Nevertheless, it will be damaged during heating, for example when it is used for frying as linoleic and linolenic are more sensitive to heat than oleic. It also must go through the process of hydrogenation in order to increase the stability. This makes oil hydrogenation produces trans fat which is also bad for the heart. Several efforts have been done, such as natural pollination research by the team of researchers from the University of Missouri and rotation with corn by Nacer Bellaloui et.al. (2010) to increase the oleic in fatty acid composition of soybean oil, because it is more stable to heat so it does not require hydrogenation.

Benefits of castor oil

Benefits of castor oil is to replace diesel oil as the generate electrical power. The tree can be cultivated in almost all regions of Indonesia. So, this help people to meet the energy needs of remote areas and this power can be produced by the communities that need electricity. Research about this new commodity has been conducted by Dr. Ir Robert Manurung MEng, lecturer in the Department of Industrial Chemistry Institute of Technology Bandung (ITB), accompanied by Eiichi Kobayashi Masanori Nagayama and from New Energy and Industrial Technology Development Organization (NEDO), under the Japanese Government agency that helps the research of new energy sources. Castor oil is obtained from Jatropha curcas L. which is a bush family of Euphorbiaceae. Within five months, this drought-resistant plants is starting to bear fruit, full productive at the age of five years old, and its productive life reach 50.
In fact, a coal mining company and a Japanese manufacturer of heavy equipment operating in Indonesia have developed new business opportunities in the form of the production of fuel from castor oil. The capacity is expected about 8,000 tons per year by 2012. This natural power resources is expected to live 100 units of mining dump trucks with a capacity of 90 tonnes used in coal mines in South Kalimantan. The biodiesel from jatropha would replace 20 percent of fossil fuel use which can not be recycled. To obtain the planned capacity of 8,000 tons per annum, this requires 4,000 hectares of cultivation land.
In addition, benefits of castor oil is to improve people's welfare, especially in areas with low natural resources. If each farmer were given the right to manage three acres of dry land, with a density of 2,500 trees per hectare and the productivity of 10 000 kilograms beans per hectare and the price of IDR 500 per kilogram of seed, of a family farmer can earn IDR1.25 million per month from the beans. Castor oil can be obtained by simple direct expelling or pressing so that an investment of IDR 3-4 million is sufficient to produce 40 liters of oil per day. Unlike other biodiesel, it does not need any additional ethanol or methanol. Its use could also be 100 percent, no more diesel fuel to be mixed, said Manurung.
In terms of health, jatropha vegetable oil also has anti-microbial properties of pathogenic bacteria, which in the form of soap, it is more active soap to get rid of the bacteria S. aureus and E. coli than any other vegetable oil-based soap. According Aprilian Salis, from PT Pertamina DOH Kalimantan, if properly managed, the benefits of castor oil could reach 30 to 40 percent of total fuel consumption in Indonesia.

How to store cooking oil properly

How to store cooking oil properly is as follows. It should be kept in a dark-colored packaging. It is intended to avoid rancidity, because of oxidation due to contact with air and is triggered by ultraviolet in the sunray. Recently, it is sold in the market in transparent or translucent-colored package. It aims to be easily visible. In addition, the consumer preference to its packaging is transparent. Yet this preference is not appropriate because it can be easily oxidized, so it becomes rancid. Store cooking oil properly in sealed containers and away from heat sources such as light, stove, and the sun! The bad habit to put it near a heat source will cause fortified vitamin A will be reduced even in very small amounts. Vitamin A contained will be damaged because vitamin A is one of micro substances which is sensitive to acid and oxidation when exposed to direct sunlight, and easily damaged by heat. So, the key to store cooking oil properly is keep it away from the factors inducing its deterioration, such as UV, heat, air, and even metals.
