Development of a recipe for bakery products with extrudate oat grain for small enterprises | Разработка рецептуры хлебобулочных изделий с экструдатом зерна овса для малых предприятий
2020
Shaburova G.V. | Shmatkova N.N.
Large bakery enterprises operating in a three-shift mode, in their technological processes, mainly use methods for preparing dough on a thick dough, accelerated uncooked and uncooked methods. For small-scale production, these methods are not suitable due to the special mode of operation of most bakeries and workshops for the production of bakery products (CBI). The use of accelerated methods of processing raw materials increases the cost of finished products in connection with the use of improvers and acidifiers. Given the operating mode of small bakeries, it should be considered rational to use the cold poolish technology, characterized by prolonged fermentation for 12-24 hours with a minimum amount of yeast in the dough. Increasing the nutritional and biological value of products on poolish dough is ensured by the use of extruded oats with a modified chemical composition in exchange for a portion of wheat flour. Finished products were characterized by increased specific volume and porosity. The physicochemical and organoleptic characteristics of the French baguette produced by innovative technology met the requirements of the state standard. Baguette had good taste and aromatic characteristics, attractive appearance, elastic crumb with uniform porosity.

Gaponova V.E. | Slezko E.I. | Isaev H.M.
A) Sales of bread and bakery products in Russia for 2015-2019 are decreasing. In general, over a five-year period, they decreased by 5.4 % and in 2019 amounted to 7.59 million tons [1]. A similar situation is observed in the Bryansk region. Consumption of traditional bakery products in the period 2014-2019 decreased by 9 % [2]. The movement of the population towards proper healthy nutrition is becoming more and more stable and the existing assortment does not meet the needs of the modern consumer. There is a need to search for new approaches to solving this issue. The search for a solution to the issue of obtaining healthy bread sometimes finds an answer in the old recipes of different peoples. Thus, in Gagauzia, bread is still baked using dry sourdoughs derived from grape must, a mixture of wheat or corn flour. b) The purpose of the research was to develop a technological process for producing wheat bread based on dry sourdough based on grape must, to determine the organoleptic and physicochemical characteristics of such a bakery product, to develop a technical and technological map of this product. The object of research was baked wheat bread, prepared on the basis of sourdough from grape must and corn flour. The starter culture was subjected to microbiological research in the laboratory of the Federal Service for Veterinary and Sanitary Supervision of the Federal State Budgetary Institution «Bryansk Interregional Veterinary Laboratory» (extract from the Test Protocol No. 18-10999 dated 30.05.2018). Evaluation of organoleptic indicators (appearance, crust color, crumb condition, smell, taste) according to GOST 5667-75 and physical and chemical: humidity (GOST 2109-75), porosity with Zhuravlev’s probe (GOST 5669-96), acidity (GOST 5670-96). c) Wheat bread made from grape must, the process is not complicated, but time-consuming. It takes 6-7 hours to prepare the dough. The process of creating a dough takes place in 2 stages (the first is the soaking and swelling of the starter cake; the second is the proliferation of yeast cells). The kneading and ripening of wheat bread dough is 2-2.5 hours. The moisture content of the dough is 50%, the duration of the whole process of making bread takes 8-10 hours. The energy value of the product was 242 kcal. The product yield was 160 %, the acidity of the finished product was 4.3. The mass of one bakery product was 730-740 g. It is necessary to bake such bread at a temperature of 190-200 °C. d) Baked wheat bread was distinguished by high taste, organoleptic and physico-chemical characteristics. Such bread does not cause bloating in the intestines and has a beneficial effect on its microflora.

Garkina P.K. | Gorbacheva O.N.
One of the priority areas for the development of the production of flour confectionery products is the creation of products with reduced energy value, adequate to the needs of various groups of the population in chemical composition, energy and biological value of products. The most popular among the population flour confectionery products include cookies. However, a high content of fat, sugar, and a low or complete absence of dietary fiber and vitamins leads to an imbalance in the diet by nutrients and calories. The analysis of scientific, patent and technical literature indicates the possibility of reducing the energy value of flour confectionery products by replacing energy-intensive nutrients or adding pectin, lignin, microcrystalline fiber, vegetables, fruits, berries, bran, crushed grain, dairy products, non-fat and non-fat oil flour crops and others. Fruits and berries can be promising sources of vitamins, bioflavonoids, macro- and micronutrients and dietary fiber when developing recipes for flour confectionery products. At the same time, the use of local raw materials is important. It has been established that various types of blueberries, cranberries, blueberries, hawthorn, suitable for use in scientific medicine and the food industry, grow in the Penza region. Based on the analysis of information sources, the vector of reducing the energy value of cookies by using the technological potential of hawthorn as a carrier of functional food ingredients, the stocks of which in the Penza region is 3.5 tons, is substantiated.
