Application of guar gum as a flocculant aid in food processing and potable water treatment

Guar gum is a widely used ingredient in food processing industry. This work highlights the use of guar gum as a flocculant aid in potable water treatment. Current practice of using synthetic flocculants such as polyacryl-amide has raised controversies of acrylamide residues in water and thereby increasing health risk of the population. The flocculating effect of guar gum on the settling characteristics of flocs in a bench-scale potable water clarification process is presented in this work. Data from two experimental runs, namely, run A (guar gum and primary coagulant) and run B (primary coagulant only), were used to plot settling velocity distribution curves (SVDC). Observation of these curves revealed that guar gum increased the proportion of destabilised colloidal impurities settling above a stated minimum velocity. It was found that guar gum may be used along with alum to reduce raw water turbidity from 26.5 to 1.0. It may be concluded that guar gum can be used as a safer alternative to polyacrylamide in water treatment for drinking or food processing purposes.     

Studies of incorporation and stability of model flavouring compounds on black tea

Flavoured teas have a good potential and popularity in the export market. In the present studies, four model flavouring compounds, i.e. citronellol, phenylethylalcohol, citral and bergamot oil, were incorporated in black tea and their storage characteristics were studied at three temperature conditions, 5°C, ambient and 37°C, using laminated aluminium foil, metal can and metallised polyester as packaging materials, for a period of 90 days. These were evaluated by instrumental (gas chromatography/ultraviolet) and sensory methods. Considerable flavour loss was observed in metallised polyester package, at 37°C and during the first month of storage. The first three flavoured teas showed a shelf life of 90 days while the bergamot flavoured tea had a shelf life of only 60 days. Highly significant linear correlation was established between the instrumental and sensory values.     

水产调味品中挥发性盐基氮的测定

为提高水产调味品中挥发性盐基氮测定的效率,对国标GB/T 5009.44-2003中的半微量定氮法进行了改进:用高氯酸溶液替代水来浸溶样品;用氢氧化钠溶液加消泡剂替代了氧化镁混悬液;用自动凯氏定氮仪替代半微量蒸馏装置和半微量滴定管.用改进的方法测定以市售蚝油和虾酱为基质的加标样品,回收率在98.82％～101.26％之间,相对标准偏差在0.80％以下.检测数据与GB/T 5009.44-2003中的半微量定氮法相比,无显著性差异.结果表明,改进的方法是一种简便、快捷、精确的水产调味品中挥发性盐基氮的测定方法.

Effects of almond gum as texture and sensory quality improver in wheat bread

The aim of this work was to investigate the effect of almond gum as dietary fibre source in enhancing the wheat bread quality. Different amounts of almond gum (2%, 5% and 10% (w/w)) were used in bread formulation. The volume, texture, crust and crumb colour, as well as the sensorial properties, were evaluated and compared to control (without almond gum). The obtained results showed that almond gum addition enhanced significantly the volume of bread. The highest volume was obtained using 2% almond gum concentration with 23.6% increase, compared to control. Using almond gum in bread formulation improved considerably its texture with a notable decrease in hardness by 61.7% and 42.5% when using 2% and 5% almond gum, respectively. The sensory analysis scores showed that the better overall acceptability was found for breads supplemented with 2% almond gum, as compared to control and breads supplemented with 5% or 10% almond gum.
