Embodiment 1

[0025] The process of extracting dietary fiber from peony leaves by fermentation method uses lactic acid bacteria as a starter, inoculates the peony leaf pulp obtained by crushing, seasoning, sterilizing, and cooling the peony leaves, fermenting, drying, grinding and sieving, and seals the bag. Dietary fiber is obtained after packaging, and the process steps are as follows:

[0026] (1), treatment of peony leaves

[0027] Step 1. Select fresh peony leaves without insects as raw materials and accurately weigh them, wash them with clean water and dry them;

[0028] Step 2. Lay the peony leaves dried in step 1 on the tray for tunnel-type hot air drying, and dry them for 20 hours at a temperature of 38°C. During the drying process, weigh the peony leaves every 0.5 hours. Take out the peony leaves until the weighing weight remains unchanged for 0.5 hours, and then put them into a coarse powder in a Chinese herbal medicine grinder to obtain peony leaf powder, which is set aside;

[0039] The process of extracting dietary fiber from peony leaves by fermentation method uses lactic acid bacteria as a starter, inoculates the peony leaf pulp obtained by crushing, seasoning, sterilizing, and cooling the peony leaves, fermenting, drying, grinding and sieving, and seals the bag. Dietary fiber is obtained after packaging, and the process steps are as follows:

[0040] (1), treatment of peony leaves

[0041] Step 1. Select fresh peony leaves without insects as raw materials and accurately weigh them, wash them with clean water and dry them;

[0042] Step 2. Lay the peony leaves dried in step 1 on the material tray for tunnel hot air drying, and dry them at 42°C for 28 hours. During the drying process, weigh the peony leaves every 0.5 hours, until every 0.5 Take out the peony leaves until the weighing weight is constant in one hour, then put into the Chinese herbal medicine pulverizer and pulverize to obtain the peony leaf powder, which is for subsequent use;

Embodiment 3

[0053] The process of extracting dietary fiber from peony leaves by fermentation method uses lactic acid bacteria as a starter, inoculates the peony leaf pulp obtained by crushing, seasoning, sterilizing, and cooling the peony leaves, fermenting, drying, grinding and sieving, and seals the bag. Dietary fiber is obtained after packaging, and the process steps are as follows:

[0054] (1), treatment of peony leaves

[0055] Step 1. Select fresh peony leaves without insects as raw materials and accurately weigh them, wash them with clean water and dry them;

[0056] Step 2. Lay the peony leaves dried in step 1 on the tray for tunnel-type hot air drying, at a temperature of 40°C for 24 hours, and weigh the peony leaves every 0.5 hours during the drying process, until every 0.5 Take out the peony leaves until the hourly weighing weight is constant, then put into the coarse powder in the Chinese herbal medicine grinder, obtain the peony leaf powder, and set aside;

Abstract

A process for extracting dietary fibers from peony leaves by a fermentation method belongs to the extraction process of dietary fibers for food processing. The method is characterized by adopting lactobacillus as the fermentation agent, carrying out inoculation, fermentation culture, drying, grinding and sieving on the peony leaf pulp prepared by grinding, seasoning, sterilizing and cooling the peony leaves and packaging the products with sealed bags, thus obtaining the dietary fibers. The method effectively solves the following problems: the natural ingredients are greatly damaged in the process of extracting the dietary fibers and the biological activity of the prepared products is low, and the dietary fibers obtained by the method have higher water holding capability and higher extraction ratio.

Description

[0001] technical field [0002] The invention belongs to a process for extracting dietary fiber in food processing, in particular to a process for extracting dietary fiber from peony leaves by fermentation. Background technique [0003] Due to its unique water (oil) holding capacity, expansion and compatibilization, integrated adsorption and other physical and chemical properties, fiber food shows many physiological functions, such as improving intestinal flora, preventing and treating intestinal diseases, Relieve coronary heart disease, prevent gallstones and obesity, etc. Some western countries took the lead in proposing recommended intakes based on dietary surveys. However, different raw materials and preparation methods result in different dietary fiber components and effects. At present, rice bran, wheat bran, rye, oats, bean dregs and other grains, fruit skins and shells are mostly used as raw materials for the production of dietary fiber, while the extraction proce...
