Food Ingredients Europe 2011: Wacker presents novel stabilizers, dietary fibres and vegetarian-grade cysteine for the food and beverage industry
FOCUS most recent addition to Clariant’s portfolio of polymer-based dispersing agents for the agrochemical industry, Dispersogen ACP 120 provides a combination of features as yet unattainable with one product. The benchmark-setting acrylate-based anionic copolymer combines high efficiency at low use levels with an excellent toxicological and environmental profile. The full range of features is described. For example, suspension concentrates with improved wetting properties can be created by using Dispersogen ACP 120 together with Dispersogen PG, Clariant’s dispersing adjuvant based on renewable resources. Dispersogen PG acts as wetting and secondary dispersing agent in the suspension concentrate and is a low risk inert ingredient with no hazardous labelling. The combination results in significantly lower surface tension and improved wetting performance. The excellent stability of Dispersogen ACP 120 in the presence of high amounts of electrolytes means it can also be used to formulate stable suspension concentrates using saline herbicides. This is particularly relevant for applications requiring a second herbicide in the tank-mix, such as when targeting novel approaches to control glyphosate-resistant weeds. Clariant is an internationally active speciality chemical company based in Muttenz near Basel. The group owns over 100 companies worldwide and employed approx 16,200 employees as of 31 Dec 2010. In the financial year 2010, Clariant produced a turnover in excess of SFR 7.1 bn. Clariant is divided into twelve business units: Additives; Catalysis & Energy; Detergents & Intermediates; Emulsions; Functional Materials; Industrial & Consumer Specialties; Leather Services; Masterbatches; Oil & Mining Services; Paper Specialties; Pigments; Textile Chemicals.

application for the food and beverage industry, alpha-cyclodextrin as an emulsifier for stabilizing oil-in-water emulsions. In the food industry, oil-inwater emulsions are the order of the day. Many foods, such as salad dressings, mayonnaises, dessert creams and margarine contain both water and oil phases, which only form a stable mixture if emulsifiers are added. Traditional emulsifiers are proteins, the mono- and diglycerides of fatty acids or the lecithins found in egg yolk. Animalderived emulsifiers, however, have some critical disadvantages, they are sensitive to heat and acids, do not have a long shelf life, may contain cholesterol, and are potentially allergenic. A new approach to stabilizing oil-in-water emulsions is to use alpha-cyclodextrin. The interior of this doughnut-shaped cyclodextrin is lipophilic, while its exterior is hydrophilic (water loving). Fatty acid groups can “slip” into the interior of the alphacyclodextrin and form a surfactant structure, suitable as an emulsifier. This complex permanently stabilizes the otherwise incompatible oil/water phase interfaces of the emulsion, even at higher processing temperatures. Depending on requirements, alphacyclodextrin can adjust an emulsion’s viscosity and thus its “mouthfeel”, from fluidity similar to ketchup through to a firm texture resembling sugar frosting. As a result, there is no need for additional hydrocolloids. Wacker produces its alpha-cyclodextrin, a natural degradation product of starch, from renewable raw materials, such as corn or potatoes, using bioengineering techniques. Thus, alpha-cyclodextrin offers an alternative stabilizer for oil-inwater emulsions that is not only free of cholesterol and allergens, but is also plant-based. There is discussion of use of alpha-cyclodextrin as dietary fibre and vegetarian-grade cysteine for flavourings and bakery goods.

Smart and Advanced Materials develops new excipient French biotechnology company Smart and Advanced Materials (SAM) has developed an innovative new pharmaceuticals excipient. C+2S is
based on biopolymers and is capable of easily dissolving cancer drugs or anti-inflammatories sold in powder or tablet form. The new product is effective in very low doses and is less toxic than other surfactants currently used in galenicals (such as organic solvents). It is also easier than resorting to micronization. It can be used to increase the solubility of certain drugs and to improve their stability. This has the effect of reducing side-effects caused by overdosing. It also makes it easier to treat the most fragile patients. Commercially, it has the advantage of helping drugs producers comply with new demands from European health agencies. The first drugs using SAM’s excipient should reach the market within two years. The product is already being distributed by Safic Alcan in Europe. SAM is hoping to raise €1 M in funding in order to develop three products belonging to the same family (but more linked to compound stabilization).

LEGISLATION Malaysians fight Australian palm oil labelling legislation The palm oil industry in Malaysia is again requesting the Australian Parliament not to pass the proposed palm oil labelling bill. The proposed bill would require labelling of palm oil in food products to foster the ‘use of certified sustainable palm oil to promote the protection of wildlife habitat’. In Apr 2011, Malaysia successfully brought up its opposition to the legislation asserting that the bill was based on misleading claims and intended at hurting its biggest agricultural export, palm oil. However, the Australian Senate opted to push ahead with the bill, despite the Community Affair’s recommendation that the bill not be passed. The proposed labelling bill is now being sent to the House of Representatives.
