TBA (0.08 mg MDA/kg)‚ peroxide (4.50 mEq/kg) and TMA (3.46 mg N/100 g) values were recorded in 5% ginger extract treated samples‚ while the highest TBA (1.45 mg MDA/ kg)‚ PV(30.07 mEq/kg) and TMA (15.52 mg N/100 g) occurred in the control. The result also revealed that samples treated with ginger extract had lower mould count than the control. The organoleptic results showed that samples treated with 5% ginger extract had the best acceptance‚ and were significantly different (P ≤ 0.05)‚ when compared

Origins of the Name The word‚ Aluminium originates from the ancient Latin word for alum‚ alumen‚ which is potassium aluminum sulfate‚ meaning “bitter salt”. We pronounce the element of aluminium’s name as follows‚ al-yuh-min-ee-uhm‚ which conforms to the IUPAC pronunciation of the word‚ with the regular ‘ium’ ending of majority of the elements of the periodic table. The History Aluminium was first discovered in 1825‚ by early discoverer‚ Hans Christian Oersted in Denmark. Before this time‚ alum

eventually create an accurate picture of the molecule. The london team took an experimental approach‚ looking particularly at x-ray diffraction images of DNA. In 1951‚ Watson attended a lecture by Franklin. She had found that DNA can exist in two forms‚ depending on the relative humidity in the surrounding air which helped her deduce that the phosphate part of the molecule was on the outside. Watson and crick based on this information‚ made a failed model. It

(lipophilic). This means that they will coat the surface of oil droplets in an oil-in-water emulsion and effectively ’insulate’ the oil droplets from the water. It keeps them evenly dispersed throughout the emulsion and stops them from clumping together to form their own‚ separate layer. In a water-in-oil emulsion‚ the emulsifier coats the water droplets to stop them from separating from the oil. This property makes emulsifiers indispensable in the modern food industry where foams‚ suspensions (particles
