以园艺废弃物芒果皮为原料，在合理的温度和压力条件下，采用水热法提取果胶。从两个芒果品种即Calypso（澳大利亚）和Totapuri（印度）中获得了较高的果胶平均产量（15.7%，27.2%）。根据酯化度（77-89%）、分子量（Mw）（49，742 - 49，862 Da）、FTIR和胶凝试验确定物理化学特性。将废液水解以回收特定的多酚和糖。水解液体中的多酚定量为没食子酸（525.1-1405.6 mg/l）、芒果苷（7.8-162.2 mg/l）、槲皮素（40.6-49.2 mg/l）和鞣花酸（38.8-69.3 mg/l）。发现在果胶提取后作为固体副产物获得的固体残余物富含纤维素（38%）和木质素（16%）。在本文中，已尝试解决的挑战，从芒果皮中提取果胶，在传统的工艺。结果表明，芒果皮可能是一个有前途的非传统来源，用于回收食品级质量的果胶。当其他食品级副产品的回收与水胶体提取过程相结合时，以前在加工过程中花费的大量努力减少了。(C)2017爱思唯尔有限公司版权所有
An environment-friendly hydrothermal process was developed to extract pectin from a horticultural waste, namely mango peels, at a reasonable temperature and pressure. High average yields of pectin (15.7%, 27.2%) were obtained from the two mango cultivars namely, Calypso (Australian) and Totapuri (Indian). The physico-chemical characteristics were determined in terms of the degree of esterification (77-89%), molecular weights (Mw) (49,742-49,862 Da), FTIR and gelling tests. The spent liquor was hydrolysed to recover the specific polyphenols and sugars. The polyphenols in the hydrolysed liquid were quantified as gallic acid (525.1-1405.6 mg/l), mangiferin (7.8-162.2 mg/l), quercetin (40.6-49.2 mg/l) and ellagic acid (38.8-69.3 mg/l). The solid residue obtained as a solid co-product after pectin extraction was found to be rich in cellulose (38%) and lignin (16%). In this paper, an attempt has been made to address the challenges of the extraction of pectin from mango peels, in a conventional process. It was demonstrated that mango peels may be a promising unconventional source for recovery of food-grade quality pectin. Considerable efforts, which were earlier expended in the processing, were reduced when recovery of other food-grade co-products was integrated with the process of hydrocolloid extraction.
