    • A xanthan gum having an improved transmittance is disclosed. Further, the transmittance of the xanthan gum is at least 75% in an 1% by weight aqueous solution. The xanthan gum is prepared by subjecting a strain ATCC 55429 or ATCC 55298 to submerged fermentation conditions to produce a broth containing the gum and debris. The broth is then subjected to heating at a temperature from 45.degree. to 70 .degree. C. for a period of time of at least one half to two hours and at a pH of 9 to 12.5. Two enzyme treatments are performed using an alkaline protease and lysozyme of which the order of their application is irrelevant to the recovery of the xanthan gum. The enzymes are applied at specific temperatures and time periods as well as pH conditions such as a protease is applied at a temperature of 40.degree. to 65 .degree. C. for a period of from 20 minutes to five hours at a pH range of 6 to 10; and the lysozyme is applied at a temperature of 25.degree. to 60 .degree. C. for a period of 20 minutes to five hours at a pH range of 5.5 to 8.0. Both of the enzyme treatments are applied after the broth has been heated in step b) and before the recovery of the xanthan gum.
    • 公开了具有改善的透光率的黄原胶。 此外,在1重量%水溶液中,黄原胶的透光率为至少75%。 黄原胶通过使菌株ATCC 55429或ATCC 55298经受浸没发酵条件制备含有牙龈和碎屑的肉汤来制备。 然后在45℃至70℃的温度下将肉汤加热至少一半至两小时,pH为9至12.5。 使用碱性蛋白酶和溶菌酶进行两种酶处理,其应用顺序与黄原胶的回收无关。 酶在特定的温度和时间段以及pH条件例如蛋白酶在40至65℃的温度下施用,时间为20分钟至5小时,pH范围为6至10 ; 将溶菌酶在25〜60℃的温度下,在5.5〜8.0的pH范围内进行20分钟〜5小时。 在肉汤在步骤b)中加热并且在黄原胶回收之前,都应用两种酶处理。

    • A modified xanthan gum has a viscosity of not less than 800 cP as determined on a 0.5% by weight solution thereof in a 12% by weight aqueous sodium chloride solution at 20.degree. C. and a ratio of this viscosity to that determined on a 0.5% by weight solution thereof in distilled water of not less than 1.5. The modified xanthan gum can be prepared by a method comprising the steps of mixing an organic solvent which does not dissolve xanthan gum and is hydrophilic with an aqueous solution of xanthan gum in a mixer, cutting, into fine fibrous materials, deposites formed in the mixed solution together with the mixed solution with a cutter, separating and recovering the suspended fine fibrous materials from the mixed solution and then drying the materials at a temperature of not more than 80.degree. C. The modified xanthan gum can directly be dissolved in aqueous solutions of salts such as common salt even at room temperature and can thus easily show a desired effect of thickening the aqueous salt solutions.
