Pectic acid, also known as polygalacturonic acid, is a water-insoluble, transparent gelatinous acid existing in over-ripe fruit and some vegetables. It is a product of pectin degradation in plants, and is produced via the interaction between pectinase and pectin (the latter being common in the wine-making industry.) In the early stage of development of fruits, the pectic substance is a water-insoluble protopectin which is converted into pectin by the enzyme protopectinase during ripening of fruit. In over-ripe fruits, due to the presence of pectic methyl esterase enzyme, the pectin gets largely converted to pectic acid which is water-insoluble. Due to this reason both immature and over-ripe fruits are not suitable for making jelly and only ripe fruits are used.

Method for extracting pectin and synephrine by utilizing peels and marc
InactiveCN101875703ASuitable for large-scale industrializationReduce manufacturing costOrganic compound preparationAmino-hyroxy compound preparationPectinaseEvaporation
The invention relates to a method for extracting pectin and synephrine by utilizing peels and marc. The pectin comprises three types of protopectin, water soluble pectin and pectic acid, wherein the former is not soluble in water, and the two latter are both soluble in the water. A great number of pectin components and synephrine components exist in the peels and the marc. In the invention, a pectin product is prepared by utilizing a biocatalyst without high temperature and high pressure reaction in the production process, extracting the pectin through effective bonding of acidolysis and enzyme, eliminating the destructive action of pectinase to the pectin through high temperature enzyme killing, releasing the pectin and the synephrine under an acid condition, and extracting and purifying the pectin through a subsequent extraction technology; and a synephrine product is also prepared through resin adsorption, falling film evaporation in waste liquid after the pectin product is prepared. The invention does not relate to toxic chemicals and operation under the room temperature and the normal pressure, is suitable for large scale industrialization, and can dramatically lower the production cost.

ActiveCN104366392AAvoid soft rotReduce microbial countConfectionerySweetmeatsOrganic acidAlcohol sugars
The invention discloses a processing method of sugar-free preserved green plums. According to the method, a salt pickling step is omitted; sugar alcohol type substances including xylitol, maltitol and the like penetrate into green plums so that the sweetness of the green plums is increased; meanwhile, part of contained organic acids can be transferred out; the content of the organic acids is reduced by using microbial fermentation so that a sweet-acid ratio suitable for eating is obtained; and in the process, the rigidity and the crispiness of the green plums are increased by the common effects of pectin methylesterase and calcium ions, so that the sugar-free healthy green plums which are suitable for being directly eaten are obtained. According to the method, the pectin methylesterase is used for catalytically hydrolyzing methoxyl of pectin to obtain pectic acid; the calcium ions obtained by ionizing the pectic acid and calcium lactate act with one another and the rigidity and the crispiness of the green plums are improved in the existence of a bridging effect of the calcium ions; and the problems that pulp is soft and rotten in processes of pickling and fermenting the green plums, and storing the preserved green plums are solved.
