Introduction


Palm-based Trans-free Whipped Topping as an Alternative to Dairy Cream

Vegetable fat-based whipped toppings is used as a replacement for whipped dairy cream are commonly called whipped toppings, non-dairy cream, imitation cream and vegetable cream (Neil and Hogg, 2003). Whipped cream is an aerated food emulsion which is normally produced from milk fat. It has a white opaque appearance and low density due to the high inclusion of gas bubbles in the system. The emulsion droplets usually contain partially crystallized fats (Aken, 2001). Whipped toppings have become popular both for commercial and consumer use on puddings, sodas, cakes, ice cream, fruit and pastries such as cream pie bases. Consumers and manufacturers have certain expectations for the quality of whipped toppings with regard to taste, shelf-life and whipping characteristics, such as speed of whipping, overrun and stability (Shamsi et al., 2002).

Introduction


Palm-Based Trans-free Roll-in Margarine

Fats used for formulating shortening and margarine require a certain amount of solids. These solids are mainly obtained by the catalytic hydrogenation of liquid oils. However, hydrogenated fats are undesirable in food formulations as they contain trans fatty acids. Trans fatty acids (TFA) were reported to be a cholesterol-elevating agent, raising the low density lipoprotein (bad cholesterol) and lowering the high density lipoproteins (good cholesterol) in humans (Mensick and Katan, 1990; Judd et al., 1994). Epidemiological studies have suggested a link between the consumption of TFA and coronary heart disease risk (Hennekens and Willett, 1997). Palm-based oils and fats are considered to be a potential replacement for hydrogenated fats as they have natural solid components easily obtained by fractionation, and they do not contain TFA (Berger and Idris, 2005; List and King, 2006).

Introduction


New evolution of Palm-based Standard Reference Materials

Palm oil is one of the most important sources of revenue to Malaysia. Exports of palm oil from the country increased by 41.8% in 2007 compared to that of in 2006. Of this total amount, more than 70% of palm oil exports comprise mainly refined, bleached and deodorized (RBD) palm oil, RBD palm olein and RBD palm stearin. As a leading country in the palm oil business, it is necessary for Malaysia to ensure that palm oil is of good quality. Therefore, harmonization of palm oil test methods is crucial to produce palm oil within the trade specifications. A comparison of the measurement results should be made against the certified values of standard reference materials to ensure the reliability and trueness of the methods used. However, the unavailability of standard reference materials from palm oil products prevents this from being practised. With the emphasis on quality aspects, the Malaysian Palm Oil Board (MPOB) has taken initiatives to develop Palm-based Standard Reference Materials (SRMs) to cater for the needs of the industry in monitoring the quality of the palm oil produced. Several studies have commenced on the production of such SRMs.

Introduction


The plumbing system in our body - Angiogenesis and cancer

Our vascular system which consists of mainly blood vessels is something comparable to a plumbing system within our body through which blood circulates, transferring various supplies that are essential for the growth of our body as well as ridding it of wastes. Proteins, vitamins, minerals, ions or even waste are transported from one part of the body to the other through this complicated vascular network. Being an important structure, blood vessels are generated whenever necessary. The process that is responsible for generating blood vessels in the body is known as angiogenesis. It is a physiological process involving the formation of new blood vessels from the existing or established vessels found in the body. Angiogenesis is a normal process in growth and development, as well as in wound healing. However, it is also a fundamental step in the transition of tumours from a dormant state to a malignant state as angiogenesis also provides the blood vessels to tumours, feeding them with nutrients for further growth.

Introduction


Quality of some fatty acids produced in Malaysia: An update

Today’s market is becoming more and more demanding of fatty acids with high quality. The fatty acid industry is one of those that are experiencing rapid growth in the Malaysian oil palm industry. It has expanded significantly since the first fatty acid plant was established in 1979. Nowadays, many new fatty acid plants have been built in the Southeast Asian region, using palm oil and coconut oil as the major sources of raw materials for the production of caproic to oleic acids. The export of Malaysian fatty acids has increased by five times in 10 years, from 190 178 t in 1997 to 913 283 t in 2006 (Figure 1). The value of export has also increased by six times in the same period. The export in 2006 was increased by 133 218 t or 17.1% compared to 2005. Fatty acids are the main oleochemical produced in Malaysia, comprising 42.3% of the total oleochemicals exported in 2006 (MPOB, 1998-2007). Figure 1 also shows that the trend of fatty acid export has increased year by year since 1999. Availability of raw materials and good infrastructure has turned Southeast Asia into a manufacturing hub for the fatty acid industry. Fatty acid producers in Malaysia and Indonesia are also enhancing their manufacturing capacities in response to the increasing demand.

Introduction


Utilization of oil palm products in the formulation of cheese powder

Cheese is a food made from coagulated curds that are pressed together to form a solid that is usually allowed to ripen. The main milk components (protein, fat and minerals) are concentrated and protected from rapid deterioration by spoilage micro-organisms. Many industrial food applications are dependant on the delivery of an authentic cheese flavour; however, food manufacturers have continually sought for alternatives due to the requirement to refrigerate fresh cheese. By far, the most efficient way to incorporate the natural goodness of cheese has been through the use of cheese powders. Cheese powders are a convenient and economical alternative to block cheese. They offer the entire flavour, functional and nutritional attributes associated with natural cheese. Savings from reduced raw materials, shipping and storage costs can also be considerable. Up to a year in product shelf-life and significant blending advantages make cheese powder a logical choice for many food processors and in other applications. The potential application for cheese powders extends far beyond traditional snack seasonings and dry boxed convenience dinners where low moisture and long shelf-life without refrigeration demand their use. Cheese powder systems also deliver exceptional combinations of cheese and dairy flavours while maintaining a label-friendly identity. Kerry, an Irish-based company, is one of the leading suppliers of spray-dried cheese and dairy flavourings.

Introduction


Prices of Selected Oils and Fats and Prospects of Palm Oil Price in 2007

Prices of most oils and fats were generally bullish during the period of 2001 to 2004. They moved in tandem, forming a general up trend during the period. However, they were bearish the following year, then recovered in 2006. But this was not the case with cottonseed oil where price independently followed a different pattern since 2001. In 2007, the prices are expected to continue to strengthen. As indicated by their performance in the first-quarter of 2007, they will continue to perform better for the remaining months of the year. The most notable will be the palm oil. The high demand for palm oil has led to a decline in its stocks and, consequently increase in its price.

Introduction


Palm Oil Supply and Disappearance: A Review

There was an increase of 6.1% in the Malaysian production of palm oil from 14.962 million tonnes in 2005 to 15.881 million tonnes in 2006 (Table 1). This was a smaller growth than 2005 over 2004, of 7.1%, suggesting that the palms were in a slower production in their cycle.

Introduction


Tocotrienol Levels in Adipose Tissue of Benign and Malignant Breast Lumps in Patients in Malaysia

Breast cancer worldwide affects nearly one million women per year and although current treatments do help many patients, more than 350 000 die from the disease. In the United States, 215 990 women were diagnosed with breast cancer in 2004 and 40 110 died from the disease (American Cancer Society, 2004). In Malaysia, breast cancer is the most frequent cancer amongst women. In 2002, the National Cancer Registry recorded 4337 new cases of breast cancer in Malaysia, which constituted 30.4% of all cancers in women (National Cancer Registry, 2003). The established risk factors for breast cancer include a family history of breast cancer, early menarche, late age at first childbirth, late age at menopause and history of benign breast disease. With the exception of the genetic predisposition to the disease, the rest of the risk factors point to the life time exposure of women to estrogen. Estrogen does not cause the disease, but is involved in the progression and development of breast cancer. Anti-estrogens are therefore used as therapy in the control of breast cancer progression.
