TT No. 563: NutraMee – A Lipophilic Antioxidant Noodle

Norsuzaini — Tue, 18 Feb 2020 15:26:44 +0000

Noodles are staple food in many Asian countries and account for more than 12% of global wheat production each year (Euromonitor, 2013). The world market size for noodle products had reached a total value of USD 2300 million in year 2013. Market players are aware of health concerns and some have initiated moves to provide healthier options (Euromonitor, 2013). Many functional ingredients have been added into noodle formulations to provide better nutrition profile. Red palm olein, a unique product from crude palm oil, which is the richest natural source of carotenes (500-1500 ppm) and a rich source of tocols (700-1000 ppm) (Choo et al., 1993; Mayamol et al., 2007) is formulated into a stable delivery system and incorporated into the noodle.

TT No. 562: Palm-based Prebiotic Ice Cream

Norsuzaini — Tue, 18 Feb 2020 15:26:01 +0000

Ice cream is a complex combination of partially frozen foam of emulsion held together by emulsified fat. Ice cream is made by freezing and aerating pasteurised mix with agitation to incorporate air for a smooth and good consistency. Dairy fats are commonly used in the production of ice cream. They are primarily derived from milk, cream, butter and anhydrous milk fat. Milk fat is the major fat component in ice cream. The fat component contributes to the richness of flavour in ice cream. However, vegetable fats such as palm oil, palm kernel oil and coconut oil are being used to replace milk fat in ice cream. Besides being comparatively cheaper than milk fat, palm oil and its fractions are widely available. These oils could be tailor-made to meet the specific requirements for ice cream fat such as the melting point, solid fat content and fatty acid composition.

TT No. 561: Palm-based Rolled Fondant

Norsuzaini — Tue, 18 Feb 2020 15:25:32 +0000

In culinary arts, the word fondant can refer to one or two types of sugar-based pastes used in preparing and decorating cakes, pastries and confectioneries. There are two types of fondant: 1) poured fondant, and 2) rolled fondant. Poured fondant is a sweet, creamy paste that can be used as a filling or icing for pastries. Rolled fondant is almost like very sweet dough. Not many scientific papers on rolled fondant are available. Most literatures are limited to recipe books. Butter has been the established fat suggested in many recipe books for this sugar/fat mixture (Knott, 2013; Parrish, 2013; Deacon, 2003). Functionally, fat affects the melting point, viscosity and body, crystallinity and spreadability of many foods (ADA Reports, 2005). The same thing applies in rolled fondant. The amount of fat may influence the quality characteristics of the final product. In a sensory evaluation on cake frostings by Drewnowski and Schwart (1990), reported that the acceptability of cake frostings was a combined function of sucrose and fat levels.

TT No. 560: Palm-based Batik Wax

Norsuzaini — Tue, 18 Feb 2020 15:25:00 +0000

In general, it is well-known that vegetablebased waxes have many industrial applications and environmental benefits against petroleum-based wax. One of the many examples is in the production of candles. However, there are other areas where vegetablebased waxes can play a significant role. One of which is in the making of batik prints or designs. Batik printing is a process of decorating plain fabrics by covering a part of the material with a layer of wax and then dyeing the whole fabrics. The waxed areas would maintain their original colour because they are not dyed. When the wax is removed, the contrast in colours between the dyed and undyed fabrics gives the desired patterns. The unique characteristic effects of this technique are contributed by the fine cracks that are present in the wax, which allow small amount of dyes to seep in, thus giving some spectacular ecstatic batik designs. Batik wax exercises an important function in the process of batik printing. Proper usage of wax results in an impeccable batik works. A traditional recipe for batik wax is a mixture of beeswax and paraffin. But most of the batik today is painted using synthetic waxes.

TT No. 559: Palm Lipstick Base

Norsuzaini — Tue, 18 Feb 2020 15:24:20 +0000

Lipstick base is a substance that is used to make lipsticks, balms or lip glosses. Lipsticks are intended to impart attractive colours, enhance the appearance of lips and hide unattractive features, such as very thick or very narrow lips. A lipstick is a combination of lipstick base and pigments. The major components of a lipstick base are oils and waxes. The addition of pigments to a lipstick base offers a wide range of colours appealing to consumers. Currently, castor oil, jojoba oil, bees wax, candelilla wax, carnauba wax, lanolin and ozokerite are used predominantly in lipstick formulations. Oils contain fatty acids, for example, castor oil consists of ricinoleic, oleic, linoleic, linolenic, stearic, palmitic and dihydroxystearic. All fatty acids except ricinoleic can be replaced by palm oil and its derivatives such as middle chain tryglyceride, isopropyl myristate, octyldodecyl myristate and cetyl alcohol. To add functionality, palm-based vitamin E can be added to enhance its antioxidant properties. This technology on palm lipstick base uses 60% palm-based materials.

TT No. 558: Tocotrienol-based Facial Mask

Norsuzaini — Tue, 18 Feb 2020 15:23:47 +0000

Water-cast gels are used as facial masks with the potentials to adhere to the keratinous surface, hydrate and deliver the enriched supplements across the skin epidermis. The term hydrogel describes three-dimensional network structures obtained from a class of synthetic and/or natural polymers which can absorb and retain significant amount of water. The hydrogel structure is created by the hydrophilic groups or domains present in a polymeric network upon hydration in an aqueous environment (Rosiak and Yoshii, 1999). Interestingly, the skin is the largest organ of the human body and the logical target for supplement delivery. Gels have potential as supplement delivery systems because of their ease of administration and hydration on contact with keratinocytes surfaces on the skin that allow diffusion out of the gel. However, gels are limited by low supplement loading capacity because of their thin nature and not all gel forming polymers are bioadhesive.

TT No. 557: Palm-based Shower Gels with Natural Exfoliating Agents

Norsuzaini — Tue, 18 Feb 2020 15:23:14 +0000

Shower gel, also known as bodywash, is the general term for liquid soap. It is available either in emulsion or clear types of products and used as a skin cleansing agent during showering or bathing. Shower gels are a combination of surfactants, water, skin conditioning agents and fragrances. It has chemical advantages over soap because it is milder at cleansing and less irritating to the skin, lathers better in hard water areas and does not leave a mineral residue on the skin or in the bath tub after usage. Almost all commercial shower gels are formulated with petroleum-based materials (Wikipedia). The objective of this technology is to promote the utilisation of palm-based materials in shower gel products. Palm-based shower gels (Figure 1) were formulated with mild surfactants, 83% palmbased materials and natural exfoliating agents, tea tree leaf, apricot kernel and rice scrub.

TT No. 556: Palm Oil-based Memory Foam

Norsuzaini — Tue, 18 Feb 2020 15:22:41 +0000

Unlike conventional flexible polyurethane (PU) foams, memory foams are characterised by their slow recovery after compression. For example, when the human hand is positioned (Figure 1) on the memory foam, the foam progressively conforms to the shape of the hand, and after the hand is removed, the foam slowly resumes to its initial shape. In general, memory foams are used in pillows, upholstered furniture, flooring underlays, cushioning, and as foams for noise and vibration harshness (NVH) control (Figure 2).

Memory foams are produced mostly via slab-stock process with toluene diisocyanate (TDI) based formulations. Recent trend in development of methylene diphenyl diisocyanate (MDI) based formulations for manufacturing of both slab-stock and molded memory foams are driven by the need for performance and processing improvements as well as environmental (regulatory) demands and safety concerns (Smiecinski and Neff, 2006) This technology relates to the development of environmental-friendly memory foams made from palm oil-based polyols (Pioneer E-120 and Pioneer ES-145). These memory foams contain MDI as the polyisocyanates component, palm oil-based polyols and petroleum-based polyols in the presence of additives and water as a blowing agent.

TT No. 555: Palm-based Emulsion in Water (EW) Termiticides

Norsuzaini — Tue, 18 Feb 2020 15:21:55 +0000

Termites are known to impact negatively on agriculture and construction industry imposing great damage to plantations and buildings. Financial loss due to termites infestations in Malaysia was estimated at RM 8- RM 10 million annually (Lee, 2002). The common method in termites control is by the use of emulsifiable concentrate termiticides. Such emulsifiable concentrates (EC) are petrochemicals-based and may pose risks to humans, animals, plants and ecosystem. Current EC-termiticides may cause skin and eye irritations. Recently, the pesticide industry has made a good progress in using low risk, environmental friendly pesticide formulations. There is a growing demand for environmental-friendly water-based pesticide formulations such as palm-based emulsion-in-water (EW) (Ismail et al., 2003; 2007). Palm-based EW consists of pesticides dissolved in water immiscible solvent, dispersed in oil phase droplets in the presence of surfactants.

TT No. 554: Production of Medium Density Fibreboard (MDF) from Empty Fruit Bunch (EFB) with Wood Fibres Mix

Norsuzaini — Tue, 18 Feb 2020 15:21:14 +0000

Medium density fibreboard (MDF) is a bio-composite widely used particularly in furniture and building products. In Malaysia, most MDF plants use rubberwood (RW) as raw material, and of late the industry is facing a problem with the inconsistency in supply and the price hike of RW. Other materials such as mixed tropical hardwood (MTH) are used as part of raw materials to substitute RW for MDF production. The industry has to find an alternative material which is abundantly available, renewable and price competitive compared with normal wood. The palm oil mill produces about 22% of empty fruit bunch (EFB) from the fresh fruit bunch (FFB) being processed, and in 2013 there was about 8 million tonnes (dry weight) of EFB produced in Malaysia. Although EFB is a fibrous material, it has characteristics that are similar with other wood or lignocellulosic materials. The MDF from EFB blended with RW and MTH was produced at a pilot scale and results were very promising particularly on the mechanical properties. Optimum results were obtained for blending ratio up to 20% EFB fibres. The swelling property declined beyond the acceptable limit with higher loading of EFB fibres. All properties are below the minimum standard requirements (EN 622-5,2006) for MDF panel produced from 100% EFB fibres.
