RU2439997C1 - Method for production of aerated non-yeasted bread of wheat flour - Google Patents

Abstract

FIELD: food industry.

SUBSTANCE: invention relates to food industry. The method is as follows: one kneads dough of prime grade wheat flour, culinary edible salt, citric acid and 50°C drinking water taken in an amount calculated so that the dough moisture content is 54% in a beating chamber with 50°C tempering jacket at the kneading worm frequency equal to 4.0-5.0 s^-1; kneading proceeds during 6-8 minutes. Then air is supplied into the chamber under a pressure of 0.35-0.45 MPa and the dough is beaten at the kneading worm frequency equal to 9.5-10.5 s^-1 during 5 minutes. After kneading completion the dough is handled into 0.15 kg semi-products and baked during 30-35 minutes at a temperature of 260-280°C and relative air humidity of 75%.

EFFECT: invention allows to enhance bread quality due to stabilisation of rheological properties, extend storage life as well as extend the range of aerated non-yeasted products.

Description

The invention relates to the food industry, in particular to the production of whipped, yeast-free products.

The closest in technical essence and the achieved effect is a method for the production of beaten yeast-free bread: RF patent No. 2320174 C1, 03/27/2008, bull. No. 9, providing for the mixing of dough from wheat flour of the first grade and salt, food table and its churning under pressure of compressed air.

The disadvantages of this method are the insufficiently high quality of bakery products and their short shelf life.

An object of the invention is to develop a method for the production of whipped yeast-free bread from wheat flour, which allows to improve the quality of bread by stabilizing the rheological properties, to increase the shelf life, and to expand the range of beaten yeast-free products.

To solve the technical problem of the invention, a method for the production of knocked yeast-free bakery products is proposed, characterized in that in a knock-out chamber with a tempering jacket at a temperature of 50 ° C, at a rotational speed of the kneading organ 4.0-5.0 s ^-1 knead the dough for 6- 8 min from wheat flour of the first grade, table salt, citric acid and drinking water with a temperature of 50 ° C, taken in an amount calculated so that the humidity of the dough is 54%, then air is supplied into the chamber under a pressure of 0.35 -0.45 MPa and knock the dough at a kneading organ rotation speed of 9.5-10.5 s ^-1 for 5 minutes, after the knocking process is completed, the dough is cut into blanks weighing 0.15 kg and baked for 30-35 min at 260-280 ° C and relative humidity of 75%.

The dough is prepared in the following ratio of recipe components, wt.%:

First grade wheat flour one hundred Edible salt 1,2 Lemon acid 0.25 Water by calculation

The technical result of the invention is to improve the quality of finished products by stabilizing rheological parameters and increasing shelf life.

A method for the production of whipped yeast-free bread from wheat flour is as follows.

Wheat flour of the first grade, edible salt, citric acid, drinking water with a temperature of 50 ° C are fed into the churning chamber of a unit with a tempering jacket at a temperature of 50 ° C, hermetically closed and stirred for 6-8 minutes at a kneading organ rotational speed of 4.0 -5.0 s ^-1 . The amount of water per batch is calculated depending on the humidity of the test 54%. Then air is supplied into the chamber under a pressure of 0.35-0.45 MPa and the test is knocked down for 5 minutes at a kneading organ rotation speed of 9.5-10.5 s ^-1 . Upon completion of the whipping process, dough pieces weighing 0.15 kg are formed and baked at a temperature of 260-280 ° C and a relative humidity of 75% for 30-35 minutes.

The method is illustrated by the following examples.

Example 1

Pre-prepared recipe components: first-grade wheat flour, edible salt, citric acid, drinking water with a temperature of 50 ° C, served in a whisking chamber, hermetically closed and stirred for 8 min at a kneading organ rotation speed of 4.0 s ^-1 . Then air is supplied into the chamber under a pressure of 0.4 MPa and the test is knocked down for 5 minutes at a kneading organ frequency of 9.5 s ^-1 . After knocking down, dough pieces weighing 0.15 kg are molded and baked for 35 minutes at a temperature of 278-280 ° C and a relative humidity of 75%.

The dough is prepared in the following ratio of recipe components, wt.%:

First grade wheat flour 100 kg Edible salt 1.2 kg Lemon acid 0.25 kg Water by calculation

Water is taken taking into account the moisture content of the raw material so that the moisture content of the dough is 54%.

In the finished product, physicochemical parameters are determined and analyzed during storage. The analysis data are presented in the table.

Example 2

The dough is prepared analogously to example 1, but the mixing is carried out for 6 minutes and at a rotation speed of the kneading organ of 5.0 s ^-1 . Then air is supplied into the chamber under a pressure of 0.4 MPa and the test is knocked down for 5 minutes at a kneading organ frequency of 10.5 s ^-1 . After knocking down, dough pieces weighing 0.15 kg are molded and baked for 35 minutes at a temperature of 278-280 ° C and a relative humidity of 75%.

In the finished product, physicochemical parameters are determined and analyzed during storage. The analysis data are presented in the table.

As can be seen from the table, the finished products are characterized by a high specific volume, developed porosity and are kept fresh for up to 5-6 days.

If you change the temperature of the dough during kneading, its humidity, as well as the rotational speed of the kneading organ during kneading and kneading, the duration of these processes, then the products will not meet the requirements for the quality of knocked yeast-free bread.

The method of preparation of whipped yeast-free bread from wheat flour allows you to:

- improve the quality of beaten yeast-free bread by stabilizing the rheological characteristics;

- improve the quality of products by organoleptic and physico-chemical indicators;

- extend the shelf life of products;

- expand the range of products.
