Problems solved by technology

Since the fresh fruit itself contains a large amount of water, adding pectin solution further increases the water content in the raw materials for jam preparation, correspondingly increasing the time and difficulty of boiling and concentrating the jam, as well as the waste of energy

Abstract

The invention provides a low-sugar jam and a preparation method of the low-sugar jam. The low-sugar jam consists of dehydrated pulp, sweetener, calcium carbonate, an acidity regulator, a thickening agent and the like. Fruit raw materials are subjected to pretreatment, osmotic dehydration and pulping, and then auxiliary materials are added into the fruit raw materials to be heated and stirred to obtain a jam finished product. The pulp subjected to osmotic dehydration is used as the raw materials to prepare the jam, thereby reducing heating energy consumption, saving jam producing time, and retaining original quality of fruits well. In addition, konjak fine meal and calcium carbonate are added, sugar content and heat are reduced, dietary fiber content and calcium content in the jam are increased, the health-care effect of the product is improved, and human health is facilitated.

Description

technical field [0001] The invention relates to the field of food technology, in particular to a low-sugar jam and a preparation method based on osmotic dehydration. [0002] Background technique [0003] Fresh fruit is made into delicious, nutritious jam, which can be eaten directly or spread on steamed buns, bread or toast, and is very popular among consumers. Most fruits can be made into jam, such as strawberries, blueberries, grapes, apples, peaches, pears, loquats, apricots, mangoes, durians, pineapples, etc. Traditional jam is directly produced from fresh fruit, which has high water content and needs to be heated and boiled for a long time to concentrate, which leads to serious damage to nutrients and flavor, and also wastes energy. The traditional method of producing jam mainly has the following three defects: [0004] 1. In the process of making jam, in order to improve the taste of jam, 40-60% of the total sucrose is added, so that the sugar content in the jam is...
