Coconut-water beverage and preparation method thereof

Abstract

The invention discloses a method for preparing a coconut-water beverage. The method comprises the following steps: (1) breaking coconuts and then getting coconut water, adding an ascorbic acid the weight of which accounts for 0.1-0.15% of that of the coconut water into the coconut water, then stirring the obtained mixture so as to dissolve the ascorbic acid; (2) adding water into the solution obtained in the step (1), then stirring the obtained mixture, wherein the weight ratio of the water to the coconut water is (0.5-1.2): (4-5); (3) adding cane sugars into the aqueous solution obtained in the step (2), adjusting the sugar degree of the obtained mixture to 7.0-8.00 Brix, then adding a citric acid into the obtained product, and adjusting the pH value of the obtained mixture to 4.6-4.8; and (4) carrying out membrane filtration sterilization and ultrahigh-pressure low-temperature sterilization on the aqueous solution obtained in the step (3) so as to obtain the coconut-water beverage. The invention also discloses a coconut-water beverage. The coconut-water beverage and preparation method thereof disclosed by the invention have the advantages that because of changing the traditional heat treatment technology for sterilization and adopting the combination of low temperature membrane filtration sterilization and high pressure low temperature sterilization, the purposes of sterilization and refreshment are achieved, the unique flavor, nutrition and functional components of the coconut water are effectively kept, and the quality guarantee period of the prepared coconut-water beverage is long; and through filtering large particles in the coconut water through centrifugal filtration and membrane filtration, the prepared coconut-water beverage is clear, soft, delicate, pure and fresh.

Description

technical field [0001] The invention relates to the technical field of beverages, especially coconut water beverages, and a preparation method thereof. Background technique [0002] Coconut is a palm plant of the genus Coconut, mainly distributed in Wenchang, Qionghai, Wanning, Lingshui County and Sanya City on the southeast coast of Hainan Province, and its area and output account for about 80% of the country. Coconut water exists in the fruit cavity and is rich in nutrients and physiologically active substances, such as fructose, glucose, sucrose, amino acids, protein, fat, vitamin C, vitamin B, vitamin E, potassium, calcium, sodium, phosphorus, magnesium, Substances such as iron. Coconut water is sweet and refreshing, and can be drunk directly. It is an ideal drink for refreshing, quenching thirst, eliminating fatigue and restoring physical fitness. Coconut water is sweet in taste and warm in nature, can promote cell regeneration, and has good nutritional and health fun...

AI Technical Summary

Problems solved by technology

Coconut water is rich in a variety of active ingredients, but these substances are sensitive to heat. If the existing heat treatment technology such as UHT or high-temperature cooking method is used to sterilize, add preservatives, etc., it will destroy its physiological activity, thereby affecting its nutrition and health. health value

And the presence of rich sugars and amino acids in it makes it easy to produce "cooked sweet potato flavor", "brown sugar flavor", etc., and the taste also loses its original deliciousness
