| titleOfInvention | Method for detecting and analyzing lignin content of pear pulp |
| abstract | The invention discloses a method for detecting and analyzing lignin content of pear pulp. The method comprises the following steps of: freezing the pear pulp to be detected, homogenizing, crushing, sieving, cleaning to remove soluble impurities, and digesting and hydrolyzing pear pulp cells by use of acidification acetyl bromide to dissolve lignin; then adding sodium hydroxide and hydroxylamine hydrochloride into the digested and hydrolyzed solution to terminate the reaction, and centrifuging the solution to eliminate the influence of impurities and precipitates on absorbance measurement; and finally measuring the absorbance value at 280 nanometers by using an ultraviolet spectrophotometer, and substituting the absorbance value into a formula to calculate the lignin content. An analysis method which has the advantages of accurate analysis result, high analysis speed, simplicity in operation, high sensitivity and good reproducibility is provided for the relatively low lignin content of the pear pulp. |
