Abstract
Extraction of Pectic Acid from Citrus Fruit Peels and its Application as Textile Printing Thickener
Highlights
The citrus fruit is formed by the following fundamental parts: the flavedo, the albedo, the pericarp that contains the above mentioned parts, and the pulp subdivided in to segments and viscose containing the juice and the seeds, called endocarp
Beaker was used to boil the mixture of citrus fruit peel, water and acid, stirring spoon, and thermo meter to control the extraction temperature, weighing balance for weighing the amount of chemicals and materials used for the extraction of Pectin, PH meter to control extraction PH, launder-meter for wash fastness testing, mini dryer to dry and cure printed fabric sample and spectrophotometer to measure k/s value of the printed area [6,7,8,9,10]
This study has investigated an alternative way of extracting pectin from citrus fruit peels with minimized
Summary
The citrus fruit is formed by the following fundamental parts: the flavedo (external colored part of the peel), the albedo (white internal part of the peel), the pericarp that contains the above mentioned parts, and the pulp subdivided in to segments and viscose containing the juice and the seeds, called endocarp. The peel, rag & seeds from the juice extractors are combined with rejected fruits & becomes the source of byproducts of citrus. The peel part which includes the inner white part of the fruit contains pectin, amino acids and other materials. From byproducts of citrus fruit dried citrus pulp, Molasses, Citrus peel oil, Citrus seed oil; alcohol, pectin, & feed yeast have been produced to a lesser extent [1]. Pectin is found in most plants, but is most concentrated in citrus fruits (oranges, lemons, grapefruits) and apples. Pectin obtained from citrus peels is referred to as citrus pectin [2]
