[0036] 2. Preparation method:

[0037] (1) Weigh the stuffing and glutinous rice flour with the skin-filling ratio of 4:1-3:2;

[0038] (2) Add the weighed glutinous rice flour into water at 20°C, stir evenly, and knead it into dough;

[0039] (3) Divide the kneaded dough into pieces, flatten it, and wrap the filling into it, and knead until the surface is smooth;

[0040] (4) Place the wrapped glutinous rice balls in a -40°C ultra-low temperature refrigerator for 30 minutes;

[0041] (5) Transfer the frozen glutinous rice balls to a refrigerator at -18°C for frozen storage.

[0042] The data of the glutinous rice ball quality evaluation index of this embodiment are shown in Table 1.

Abstract

The invention discloses quick-frozen inulin rice dumplings and a preparation method thereof. The quick-frozen inulin rice dumplings comprise 60-80% of starch flour and 20-40% of stuffing; the starch flour is formed by mixing 52-57% of powder with 43-48% of water and kneading, wherein in the powder, inulin accounts for 0.5-7%, and sticky rice accounts for 93-99.5%; inulin is sweet, so that additive amount of sugar in the stuffing can be reduced when the inulin is added in the starch flour, and the inulin is high-sweetness, low-fat and low-calorie water-soluble dietary fiber, so that nutritional and health effects are also realized when people taste food; and the inulin rice dumplings have the advantages that frost cracking ratio is obviously reduced, dehydration rate is reduced in a certain degree and light transmittance is not obviously changed. The preparation method of the inulin rice dumplings is simple and easy to operate.

Description

technical field [0001] The invention relates to the field of food processing, in particular to quick-frozen inulin glutinous rice balls and a preparation method thereof. Background technique [0002] Inulin, also known as inulin, is widely found in various plants in nature. It is a chain polysaccharide formed by fructose molecules connected by β(1→2) bonds. The end contains a glucose residue, and the degree of polymerization is 2-60. Slightly soluble in cold water, easily soluble in hot water. Inulin has the ability to bind free water, which can reduce the water activity of food and prolong the shelf life of food. When the average daily intake of inulin reaches more than 2200 mg, it will have a significant regulatory effect on the physiological effects of the human body. Inulin is low in calories, about 1.5-2.0kcal / g. It can regulate blood lipids without raising blood sugar, improve the distribution of human intestinal flora, and especially promote the proliferation of bif...
