Example Embodiment

[0017] Example 1

[0018] In the production of zongzi, the following production procedures are carried out:

[0019] ① Raw material preparation

[0020] a. Clean the rice, wash and drain the glutinous rice;

[0021] b. Clean the zong leaves and boil them in boiling water for about half an hour, soak the cooked zong leaves in clean water;

[0022] ②Preparation of the extract of zong leaves: using high temperature extraction method, the extraction conditions simulate the steaming of zongzi under normal pressure, first crush 20 g of dried zong leaves, put them in the extraction container, add 200 g of boiling water, and extract 60 minutes of boiling water. The residue is filtered out, and the zong leaf extract used in this process is prepared;

[0023] ③Soaking glutinous rice: Put 100g of glutinous rice into a container, add 200g of zong leaf extract, soak the glutinous rice in the zong leaf extract for 1 hour;

[0024] ④Ultra-high static pressure treatment: The glutinous rice added with th...

Example Embodiment

[0037] Example 2

[0038] The difference between this embodiment and Embodiment 1 is:

[0039] ②Preparation of zong leaf extract: using high temperature extraction method, the extraction conditions simulate the steaming of zongzi under normal pressure, first crush 20 g of dried reed leaves, put them into the extraction container, add 400 g of boiling water, and extract 120 minutes of boiling water. The residue is filtered out, and the zong leaf extract used in this process is prepared;

[0040] ③Soaking glutinous rice: Put 100g of glutinous rice into a container, add 200g of zong leaf extract, soak the glutinous rice in the zong leaf extract for 1.5 hours;

[0041] ④Ultra-high static pressure treatment: The glutinous rice added with the rice dumpling leaf extract is vacuum-packaged in a polyethylene plastic bag and placed in an ultra-high pressure device under a pressure of 200 MPa for processing and keeping the pressure for 30 minutes;

[0042] The texture and sensory properties of th...

Example Embodiment

[0043] Example 3

[0044] The difference between this embodiment and Embodiment 1 is:

[0045] ②Preparation of the extract of zong leaves: using high temperature extraction method, the extraction conditions simulate the steaming of zongzi under normal pressure, firstly crush 20 g of dried lotus leaves, put them in the extraction container, add 300 g of boiling water, and extract 90 minutes of boiling water. The residue is filtered out, and the zong leaf extract used in this process is prepared;

[0046] ③Soaking glutinous rice: Put 100g of glutinous rice into a container, add 200g of zong leaf extract, soak the glutinous rice in the zong leaf extract for 2 hours;

[0047] ④Ultra-high static pressure treatment: The glutinous rice added with the rice dumpling leaf extract is vacuum-packaged in a polyethylene plastic bag and placed in an ultra-high pressure device under a pressure of 300 MPa for processing and keeping the pressure for 10 minutes;

[0048] The texture and sensory propertie...

Abstract

The invention relates to a method for producing glutinous rice dumplings, and belongs to the field of food processing. The method mainly comprises the following process steps of: (1) soaking rice, namely adding glutinous rice into reed leaf extracting solution and soaking for 0.5 to 2h; (2) performing ultrahigh pressure processing, namely performing ultrahigh pressure processing on the glutinous rice into which the reed leaf extracting solution is added, and maintaining pressure to ensure that the glutinous rice fully absorbs the reed leaf extracting solution; (3) wrapping dumplings, namely wrapping the soaked glutinous rice with reed leaves to obtain the dumplings; and (4) steaming the dumplings, namely steaming the wrapped dumplings until the dumplings are cooked. The dumplings preparedby the method have remarkable dumpling fragrance which is uniformly distributed from inside to outside, have golden and uniformly distributed color and luster, moderate hardness and good mouthfeel, are bouncy, have a good health-care effect, and can effectively reduce starch retrogradation phenomenon.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a production process of rice dumplings. Background technique [0002] In a broad sense, zong leaves include reed leaves, reed leaves, and lotus leaves. They are not only a packaging material, but also a "natural green food". It has great medicinal value. It has been recorded in "Compendium of Materia Medica" that Ruoye has the functions of clearing away heat and stopping bleeding, detoxifying and reducing swelling, treating hematemesis, bleeding, dysuria, and carbuncle. Studies in recent years have proved that Ruoye polysaccharides have anti-cancer effects, and have strong anti-oxidation, antibacterial, and antibacterial effects. Reed leaves contain pentosan, coixin, vitamin B 1 , Vitamin B 2 and other rich pharmacological ingredients. Lotus leaf contains a variety of alkaloids, vitamin C and polysaccharides such as lotus leaf, protonuciferine and nuciferine. It ha...
