Galangal Extract

--- A. Raw and cooked minced beef samples containing commercial antioxidants or galangal (Alpinia galanga) extract were evaluated for storage stability at 4 ¡À 1 ¡ãC. Thiobarbituric acid (TBA) values of raw and cooked samples containing galangal extract at 5 and 10% (w/w) were significantly (p < 0.05) lower than those of the controls. In raw beef, galangal extract at 10% (w/w) was as effective as -tocopherol at 0.10% (w/w) and butylated hydroxytoluene (BHT) at 0.02% (w/w) in inhibiting/minimising lipid oxidation. Galangal extract also delayed the induction period of lipid oxidation in cooked beef but was again observed to be effective at a higher concentration than the commercial antioxidants studied.

--- B. No difference in total plate count was observed in raw beef, but samples with galangal extract had higher Hunter a (redness) and chroma (colourfulness relative to the brightness of the surroundings) values. However, cooked beef treated with galangal extract or antioxidants had lower Hunter a values and total microbial counts than the control. Thus galangal extract may be a possible natural antioxidant source for meat and meat products.

--- C. It is used in various Asian cuisines (for example in Thai and Lao tom yum and tom kha gai soups, Vietnamese Hue cuisine (tre) and throughout Indonesian cuisine, for example, in soto). Though it is related to and resembles ginger, there is little similarity in taste.

In its raw form, galangal has a citrusy, piney, earthy aroma, with hints of cedar and soap (saponins) in the flavor; its flavor is a complement to its relative ginger, but galangal has little of the peppery heat that raw ginger has. It is available as a whole rhizome, cut or powdered. The whole fresh rhizome is very hard, and slicing it requires a sharp knife. A mixture of galangal and lime juice is used as a tonic in parts of Southeast Asia.
