Đặng, Xuân Cường Vũ, Ngọc Bội Hoang, Thái Hà Nguyễn, Thị Thăng Long Vũ. Thi Hoan Đặng. Thi Thanh Tuyền Antioxidants, Cactus, Extraction, Infrared-freeze drying, Opuntia dillenii, Pectin, Vietnam ABSTRACT: The extraction condition, physic-chemistry characterization, and antioxidant activity of pectin from cactus Opuntia dillenii found commonly growing in the Ninh Thuan coast, Vietnam, were studied. The extraction conditions of antioxidant pectin content, such as temperature, time, cactus-to-solvent ratio, solvent pH, and extraction numbers, were surveyed. A correlation between pectin content and antioxidant activities, and physic-chemistry characterization such as FTIR spectra, sugar composition, viscosity, solubility ability, and esterification degree of antioxidant pectin were also analyzed. The results showed that the extraction condition strongly affected (p < 0.05) and close correlation (R2 > 0.9) on pectin content and antioxidant activities. The pectin content and the antioxidant activities got the highest value at the condition (pH 4, the solvent/material of 6/1 (v/w), the extracting time of 90 min, and extracting temperature of 90 ºC). Glucuronic and galacturonic acid of antioxidant pectin occurred from 20.920 min to 21.765 min and 20.915 min to 21.779 min, respectively. Pectin possessed an esterification degree of 62.38 ± 0.94 %, viscosity of 0.893 ± 0.051 Pa.s, and fully solubility in 90 ºC. They fully dispersed into hot water and formed gelation in cold water. Antioxidant pectin of cactus Opuntia dillenii grown on the Ninh Thuan coast is useful for application in the food industry. 12 2 1000-11 2022-09-14T15:31:02Z 2022-09-14T15:31:02Z 2021-01-01 Journal article Bài báo đăng trên tạp chí thuộc ISI, bao gồm book chapter http://scholar.dlu.edu.vn/handle/123456789/991 10.13040/IJPSR.0975-8232.11(1).1000-13 en International Journal of Pharmaceutical Sciences and Research E-ISSN: 0975-8232 https://www.researchgate.net/publication/348562635_ANTIOXIDANT_PECTIN_FROM_CACTUS_OPUNTIA_DILLENII_GROWING_IN_NINH_THUAN_COAST_VIETNAM_EXTRACTION_PHYSIC-CHEMISTRY_CHARACTERIZATION_AND_ANTIOXIDANT_ACTIVITY |

ABSTRACT: The extraction condition, physic-chemistry characterization, and
antioxidant activity of pectin from cactus Opuntia dillenii found commonly growing
in the Ninh Thuan coast, Vietnam, were studied. The extraction conditions of
antioxidant pectin content, such as temperature, time, cactus-to-solvent ratio, solvent
pH, and extraction numbers, were surveyed. A correlation between pectin content
and antioxidant activities, and physic-chemistry characterization such as FTIR spectra,
sugar composition, viscosity, solubility ability, and esterification degree of
antioxidant pectin were also analyzed. The results showed that the extraction
condition strongly affected (p < 0.05) and close correlation (R2 > 0.9) on pectin
content and antioxidant activities. The pectin content and the antioxidant activities
got the highest value at the condition (pH 4, the solvent/material of 6/1 (v/w), the
extracting time of 90 min, and extracting temperature of 90 ºC). Glucuronic and
galacturonic acid of antioxidant pectin occurred from 20.920 min to 21.765 min and
20.915 min to 21.779 min, respectively. Pectin possessed an esterification degree of
62.38 ± 0.94 %, viscosity of 0.893 ± 0.051 Pa.s, and fully solubility in 90 ºC. They
fully dispersed into hot water and formed gelation in cold water. Antioxidant pectin
of cactus Opuntia dillenii grown on the Ninh Thuan coast is useful for application
in the food industry. |
