Filled milk is a milk substitute made by combining non-dairy fats or oils with milk solids. It is used to replace fresh milk products in regions where there is inadequate storage facilities or where milk is little or not produced. Brick spread is widely used in the catering and retail sectors. The applications of this product are for spreading on bread and to stir fry vegetables, rice, seafood, meat and eggs.
Tocotrienol and vitamin E enhanced oxidative stability and prevented off-fl avour in the eggs Ajuyah et al. Sandwich cookies occupy a significant place in the world market for biscuits. Soft Filling creams are widely used for filling sandwich cookies. Oil palm empty fruit bunches EFB are abundantly produced in palm oil mills from processing the fresh fruit bunches. Holocellulose, a composite of hemicelluloses and cellulose, was extracted from EFB using acidified sodium chlorite method.
There are three main types of bar soaps - opaque, translucent and transparent. The latter two are becoming increasingly important and gaining market share. They have an aesthetic appeal and are much milder than opaque soaps. Generally, there are three ways to make soap stock: Route 2 is more widely used, being the simplest and fastest, while produces the best quality product although at somewhat greater cost.
By varying the blending ratio and using oils with different degrees of unsaturation, a wide range of polyols with different hydroxyl numbers and viscosity can be produced. The wider the range of hydroxyl numbers, the more the types of polyols that can be produced for polyurethane PU foam products. PU foams can be rigid, semi-rigid or flexible for construction, furniture and automotives. With soaring petroleum prices, polyols from vegetable oils are increasingly viable alternatives to petroleum polyols.
Hand dishwashing detergents remove food soils, hold soil in suspension as well as provide long-lasting suds to indicate how much cleaning power is left in the wash water.
The skin is a barrier between the body and the environment, and any stress imposed by the environment can affect it. Cracked heels are a common foot problem, generally occurring in hot tropical climates, but also in summer and winter in the temperate countries. As with palm oil, palm oil methyl esters POME have poor cold stability.
This drawback has limited their use in low temperatures. The objectives of this research were to identify some additives suitable for reducing the pour point and cloud point of POME to improve its low temperature performance. Of the additives used, EP produced the most promising results. The biggest reduction in pour point was about The fast diminishing energy reserves coupled with increasing energy consumption as a nation develops and greater environmental awareness have led to an intensified search for viable alternate sources of energy.
Natural and renewable resources such as vegetable oils can be chemically transformed into clean-burning biodiesel. Biodiesel is a fuel substitute that is biodegradable and can contribute to alleviating environmental pollution.
Frying oils both vegetable oils and animal fats degrade with use, and beyond the limits, the excessive free fatty acids FFA , peroxide value PV and polar components preclude their further use in food applications, unless they can be purified by very effective adsorbent systems.
In this study, four adsorbents: In this study, the preparations of biodiesel from three difference feedstocks, including rapeseed oil, high acidified Chinese wood oil and trap grease, were carried out in a pilot scale of t yr-1 biodiesel production system.
The optimum operating conditions for transesterification of rapeseed oil in plug flow reactor were found to be as follows: Synergistic properties, especially low temperature properties e. The PFF was first pyrolysed in a thermogravimetric analyzer TGA to investigate their thermal characteristics and to determine their kinetic parameters. Results from the laboratory-scale pyrolysis showed that as the terminal temperature increased, the yields of solid char and total condensates decreased, but the non-condensable gases increased.
Thus, diesel fuel with poor lubricity will contribute to wear and tear in the fuel system of diesel engines. Various experiments and field trials have been conducted searching for a better, cleaner and renewable fuel either using crude palm oil, palm olein or palm methyl ester for the diesel engine.
Cetane number is a defined parameter designed to provide an indication of the ignition quality of diesel fuels. A higher cetance number means that the fuel has better ignition quality than fuels with lower cetance numbers. A fuel which has a shorter ignition delay will have a higher cetane number and vice versa. The MPOB palm biodiesel technology has since been successfully tested on a pilot scale and commercialized by transfer of technology.
To date, 18 palm biodiesel plants have been built in Malaysia and eight are currently in operation. Palm fatty acid distillate PFAD is a by-product produced from the physical refining of palm oil.
PFAD has been used in the soap-making industry, as an animal feed ingredient and as raw material for the oleochemical industry. While this Special Supplement on Palm Oil was being conceptualized and experts from different fields were being invited to contribute, the latest Dietary Guidelines for Americans were also being finalized.
As in previous versions of these Guidelines, it was anticipated that a substantial section would be devoted to the role of dietary fats and oils and their impact on human health. While the focus of the Guidelines is the health of the American population, the high-standing that American science enjoys world-wide invariably means that this document becomes a source of reference for other countries also.
As such we thought it timely to put together a Supplement on palm oil. This article highlights the importance of the role that palm oil plays in meeting the demand for oils and fats worldwide for food. On September 18, , a multidisciplinary panel of nutrition and clinical experts was convened to review the science regarding possible trans-fat replacement options and to discuss the implications for food manufacturers as they discern which options currently available for baked goods will improve overall human health.
A lower fat consumption with reduction in saturated fatty acid SFA content of the total diet has been an important strategy for the past 5 decades of cardiovascular disease CVD risk management associated with hypercholesterolemia [1—3]. Dietary fatty acid type is well established to affect total cholesterol TC with parallel changes in low density lipoprotein-cholesterol LDL-C [4,5] and is in agreement with predictive coefficients [4,6,7].
Knowledge about the effects of dietary fats on subclinical inflammation and cardiovascular disease risk are mainly derived from studies conducted in Western populations. Little information is available on South East Asian countries.
This current study investigated the chronic effects on serum inflammatory markers, lipids, and lipoproteins of three vegetable oils. Excessive rise in postprandial glycemia is associated with increased risk of developing cardiovascular diseases in patients with type 2 diabetes T2DM .
As a result, it is an important aspect to address in any treatment of diabetes . However, the role of dietary intervention, particularly in modulating dietary carbohydrate metabolism that directly contributes to postprandial hyperglycemia, is still evolving [3,4]. Dietary and policy recommendations frequently focus on reducing saturated fatty acid consumption for improving cardiometabolic health, based largely on ecologic and animal studies. Recent advances in nutritional science now allow assessment of critical questions about health effects of saturated fatty acids SFA.
Reduction in saturated fatty acid SFA consumption is traditionally a major focus of dietary recommendations to reduce coronary heart disease CHD risk. However, effects of such astrategy on clinical CHD events are surprisingly poorly established in both randomized controlled trials RCTs [1—8] and prospective cohort studies . Prior meta-analyses of RCTs have either studied the effects of very heterogeneous dietary fat interventions on very heterogeneous combinations of cardiovascular outcomes, or studied effects of dietary fat interventions on intermediate risk markers, such as blood lipids .
Furthermore, although dietary guidelines often recommend reduction in SFA consumption, such guidelines often do not highlight any specific nutrient as preferable for replacing SFA in the diet [12—14], implying that any macronutrient replacement unsaturated fats, carbohydrate, or protein will produce similar effects. Developing countries are undergoing rapid nutrition transition . From a healthy, traditional, high-fiber, low-fat, low-calorie diet, a shift is being made toward consumption of refined carbohydrates, high total fat, and red meats, along with low intakes of fiber .
It is important to note that widespread availability and commercial use of low-cost unhealthy vegetable oils have increased dietary intake of fats and trans-fatty acids TFAs . These faulty dietary habits have contributed to increases in obesity, the metabolic syndrome, and type 2 diabetes mellitus T2DM .
Tocopherols and tocotrienols represent the 2 subgroups that make up the vitamin E family of compounds, but only tocotrienols display potent anticancer activity. Although in vitro experimental evidence has been very promising, oral supplementation of tocotrienols in animal and human studies has produced inconsistent results. However, recent studies have now clarified the reasons for these discrepancies observed between in vitro and in vivo studies.
In the s, a combination of forces came together to convince the public that food products containing tropical oils contributed to their risk of coronary heart disease. Tropical oils were competing with the U. Successful national campaigns were undertaken to force food manufacturers to remove tropical oils, including palm oil, from their products and to replace them with hydrogenated vegetable oils, resulting in increased intakes of transfatty acids, which later became the target of the same advocacy groups.
Today palm oil is being touted as a suitable replacement for hydrogenated vegetable oils. A growing body of research supports that members of the vitamin E family are not redundant with respect to their biological function.
Palm oil derived from Elaeis guineensis represents the richest source of the lesser characterized vitamin E, a-tocotrienol. One of 8 naturally occurring and chemically distinct vitamin E analogs, a-tocotrienol possesses unique biological activity that is independent of its potent antioxidant capacity.
Current developments in a-tocotrienol research demonstrate neuroprotective properties for the lipid-soluble vitamin in brain tissue rich in polyunsaturated fatty acids PUFAs.
To replace dietary trans fatty acids TFA , two practical options exist: This review summarizes the relative risks for cardiovascular disease inherent in these options.
Interestingly, both types of fat have been the subject of nutritional scrutiny for approximately the last 40 years, and both have positive and negative attributes.
Only during that period has palm oil production developed to the point where it has become the major edible oil in world markets, making clinical studies of it an important objective. Vitamin A deficiency is one of the most widespread nutritional deficiencies worldwide.
Hundreds of millions of children and tens of millions of women living in Sub-Saharan Africa and Southeast Asia are at particularly high risk of the adverse health consequences associated with this largely preventable condition. Red palm oil comes from oil palms that are traditionally grown in tropical regions of West Africa and are now cultivated on a large-scale commercial basis in Southeast Asia.
Red palm oil is the richest naturally occurring source of beta-carotene, a carotenoid that the human body can convert into usable vitamin A retinol.
Early animal studies showed that high dietary saturated fat and cholesterol intakes led to increased plasma cholesterol concentrations as well as atherosclerotic lesions 1. These findings were supported by associations in humans in which dietary saturated fat correlated with coronary heart disease CHD risk 2, 3. The position of fatty acids in the TAG molecule sn-1, sn-2 and sn-3 determines the physical properties of the fat, which affects its absorption, metabolism and distribution into tissues, which may have implications for the risk of CHD.
The TAG structure of fats can be manipulated by the process of interesterification, which is of increasing commercial importance, as it can be used to change the physical characteristics of a fat without the generation of trans-fatty acids. Interesterified fats rich in long-chain SFA are commercially important, but few studies have investigated their health effects. The NF-kB family of transcription factors regulates genes that are critical for inflammation and immunity.
In most cells, NF-kB function is induced upon activation of cells by various stimuli.
