Abstract

The invention relates to the technical field of food processing, and particularly discloses low-sugar haw jelly and a preparation method thereof. The preparation method of the low-sugar haw jelly provided by the invention comprises the following steps: firstly, extracting to obtain high-ester pectin of haws, carrying out enzymolysis on the high-ester pectin by adopting a specific compound enzyme to obtain low-ester pectin with the esterification degree of 30-35%, and then adding cane sugar and calcium chloride into the low-ester pectin to form low-ester pectin gel with excellent properties, so as to obtain the low-sugar haw jelly. And finally, adding the low-ester pectin gel and xylitol into the haw puree to prepare the low-sugar haw jelly. The taste and texture of the haw jelly are effectively improved, the low-sugar haw jelly good in taste and appearance is obtained, the requirements of the market for low-sugar and low-calorie haw jelly are met, and the processing technology is simple, convenient to popularize and wide in market prospect.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a low-sugar hawthorn cake and a preparation method thereof. Background technique [0002] With the continuous progress of the times, people's economic level continues to improve, and people's health concepts are constantly changing. When choosing food, we no longer only look for belly wraps, and pay more attention to health and nutrition while seeking delicious food. In recent years, people are more inclined to choose low-sugar, low-calorie healthy foods. [0003] Hawthorn contains terpenoids and flavonoids and other pharmaceutical ingredients, which have significant vasodilation and antihypertensive effects, and have the functions of enhancing myocardial, anti-arrhythmic, and regulating blood lipid and cholesterol levels. It is becoming more and more popular to make hawthorn into various flavors of food leaves, and hawthorn cake, as a food form that people like to eat ...
