Preparation method of apricot kernel water

Abstract

The invention relates to a preparation method of apricot kernel water. The preparation method is characterized by comprising the following steps: mainly taking debittering wastewater of bitter apricotkernels as a raw material and carrying out fine filtering treatment on the debittering wastewater through a membrane filtering technology; recycling permeated liquid; adding water, white granulated sugar and citric acid and regulating sugar and sourness; then filling into a bottle and sealing; sterilizing, cooling and packaging to prepare the apricot kernel water. The debittering wastewater of the bitter apricot kernels is sufficiently utilized; not only can wastewater discharge be reduced, but also resources can be recycled; the preparation method is simple, the cost of needed samples is lowand the energy consumption of the resources is small; the preparation method is suitable for large-batch production of a factory; the content of flavonoid and polyphenol substances such as amygdalinin the bitter apricot kernel water is high and the color and luster are clear; the requirements of consumers on tastes can be met; compared with other apricot kernel beverages, the apricot kernel water also contains a natural spice component, namely benzaldehyde, and does not contain other spice type additives; and relatively good economic benefits can be obtained.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a preparation method of almond water using bitter almond debittering wastewater as a raw material. Background technique [0002] Bitter almond is the bitter-tasting kernel of the mature fruit of the apricot plant of the genus Apricot in the family Rosaceae. It is widely distributed at home and abroad. In China, it is mainly produced in Inner Mongolia, Hebei, Shaanxi, Gansu and other places, and the resources are very rich. Bitter almonds are rich in nutrition, containing 25% protein, about 50% crude fat, and about 10% sugar. It is reported that there are a lot of unsaturated fatty acids in almond oil, mainly oleic acid and linoleic acid, accounting for 90% of fatty acids ;Each 100g almond also contains 65.8mgVE, so almond oil has anti-aging, anti-cardiovascular disease and other effects, and is a good nourishing product. [0003] At the same time, bitter almo...

Problems solved by technology

There are many shortcomings in its peeling and debittering process: on the one hand, the water consumption is large (the ratio of solid to liquid is 1:8-1:20), the waste water is discharged more, and the environment is seriously polluted; Changes and losses in structure and nutrients

That is, in the case of industrial hot blanching, especially when chemical reagents such as sodium hydroxide are added, a large amount of functional components such as polyphenols, flavonoids, dietary fiber, amygdalin in bitter almonds will be lost and transferred to the peeling water, thus making the original precious The functional ingredients of the food become waste, and then the organic matter in the bitter water exceeds the standard, which seriously pollutes the environment after discharge and causes waste of resources; at the same time, the discharge of this polluted water is strictly prohibited by the environmental protection department

This situation seriously restricts the development of the bitter almond processing industry and needs to be solved urgently
