Problems solved by technology

However, there are few deep-processed products of aronia in China at present, so the preparation of related products has great potential for development
In view of the fact that aronia fruit is a berry, it is the simplest product to make it into juice, and its juice yield is particularly important in the fruit juice processing process. The current method adopted is basically 70% of the juice yield of aronia juice, but the loss of nutrients is relatively high. more, greatly increasing the production cost

Abstract

The invention discloses a preparation method of aronia melanocarpa juice. The preparation method comprises the following steps: taking aronia melanocarpa fruits, performing cleaning, performing pulping, adding pectinase into the pulp, performing enzymolysis, filtering the enzymatic hydrolysate to obtain a filtrate I and filter residues, adding the filter residues into deionized water, treating themixed solution by using a high-voltage pulsed electric field method to obtain a leaching solution, filtering the leaching solution, mixing the filtrate II with the filtrate I, and adding a stabilizerto obtain the aronia melanocarpa juice. By adopting the process, the juice yield of the aronia melanocarpa fruits can reach 85% or above, the utilization rate of the raw materials is remarkably increased, the production cost of the aronia melanocarpa juice is effectively reduced, and the prepared juice maintains the nutritional value of the aronia melanocarpa.

Description

technical field [0001] The invention belongs to the technical field of food, and in particular relates to a preparation method of aronia fruit juice. Background technique [0002] Aronia melanocarpa Elliot (Aronia melanocarpa Elliot), a perennial deciduous shrub of Rosaceae Aronia, is native to northeastern North America, mostly distributed from the Baltic Sea coast to the Pacific coast. my country began to introduce the species in the 1990s and planted it in the semi-arid area in the northwest of Liaoning Province. Up to now, it has rich planting resources. The fruit is a berry, with purple-black skin and dark red flesh, rich in flavonoids, anthocyanins and polyphenols. Aronia fruit tastes sour and tastes bad, but many studies have confirmed that its juice has the highest antioxidant activity among common fruits. In addition, it has anti-tumor, anti-inflammatory, prevent urinary tract infection, lower blood sugar, protect liver, treat effects of obesity. [0003] The fru...
