The main stages of production of pryaniks:
1. Kneading the dough; 2. Shape the dough; 3. Cooking; 4. Decoration; 5. Drying; 6. Packaging. Dough for boiled dumplings is prepared in three phases. 1. Cook the flour and make a broth. 2. Cooling the broth. 3. Mix the rest of the raw materials in the recipe with the broth. To prepare the decoction, syrup is first prepared from raw materials containing sugar. For this, sugar, honey, and honey are put into a boiling pot, and the temperature is heated to 70-75 degrees by adding water until the moisture content is 19-20%. The resulting syrup is put into a machine with a steam curtain, paddles, and when it cools down to 68 degrees, flour is added. After 10-15 minutes, the decoction will be ready. After the decoction cools down to 28-30 degrees, the remaining raw materials are put into the aging machine and mixed for 30-60 minutes. The moisture content of the finished dough should be 20-22%. Pryanik dough is mainly molded in FPP machine or done in ash, and multi- ton gas ovens are used for baking. The duration of cooking is 7-12 minutes for boiling pryaniks at a temperature of 210-220 degrees, and 7-12 minutes for cold pryaniks at a temperature of 200- 210 degrees. Sugar syrup is prepared by cooking in a cooking pot with water in a ratio of 1:0.4 at a temperature of 110-114 degrees and stirring for 1-2 minutes in a rotating pot to a temperature of 85-90 degrees. It is dried at a temperature of 130- 150 degrees for 90 seconds and placed in a conveyor cabinet for 5-10 hours to cool down. Production of cakes and pastries. Cakes and pastries are high-calorie confectionery products that are decorated with oil, sugar, eggs, and various flavoring agents. Pies are made in different shapes, and cakes are decorated in large sizes. According to the type of baked semi-finished products, cakes are divided into the 120 following groups: biscuit, boiled, biscuit dough made in bulk, semi-finished products, boiled semi-finished products, with increased protein, nuts, waffles; And cakes: almond-nut, protein, waffle, ushok and several semi-finished products. The types of semi-finished products - creams are as follows: Butter; Protein-enriched creams. All baked goods and creams have a different technology, for example, if we take a biscuit. Biscuit dough is made in whisking machines. For this, frozen melange or eggs are whipped with sugar for 25-45 minutes, and essence is added at the end. To reduce the time of whipping, it can be heated to 40 0 С. The volume of the product increases by 2.5-3 times when saturated with air. Then starch flour is added and mixed for 25-45 minutes. Moisture content of the dough is 36-38%. In some enterprises, special high-pressure mixing units are used (250-300 rpm). Stirring lasts 8-15 minutes. The finished dough is immediately put into greased round, four-cornered molds and quickly sent to cooking. The duration of ripening of semi-finished products is 40-65 minutes at a temperature of 190-22 0 С, the moisture content of the finished product is 22-27%. Baked biscuits are removed from the mold, left for 8 hours and then cut horizontally. Decorative semi-finished products are decorated with various creams, for example "Charlotte" cream. Cake production. Cakes are flour confectionery products, made by adding a large amount of oil, melange, and sugar, and making a dough. divided into 2 types according to preparation: - with iron softeners; - made with yeast. Dough with chemical softeners is prepared in 2 ways. 1 method, butter is whipped for 7-10 minutes (40 0 С), then sugar and melange are added and whipped for 25-35 minutes, then the dough is kneaded by adding the remaining raw materials and finally flour. 2 methods - melange, whipped with sugar for 30- 40 minutes. The butter is whipped in a separate machine, and then it is whipped by adding raw materials. Dough with yeast is prepared in the apara method. The duration of cooking is 4-5 hours. The duration of kneading the dough is 1.5-2 hours. Moisture content of the dough is 32%. The dough is left to rest for 90-110 minutes in molds, smeared with egg, sprinkled with nuts, and baked in the oven chamber. The duration of cooking depends on the weight, shape and oven temperature of the pieces of dough. For example: "Capital" cake 205-2015 0 С 25-30 minutes, "Spring" cake 100g -185-210 С- It is cooked for 18-20 minutes. The finished product is cooled for 4-5 hours, then removed from the mold. Shelf life at 180 С, -7 days for cakes made with chemical softeners, -2 days for yeast. Basic and additional raw materials are also used in the preparation of confectionery products. Depending on the condition of these raw materials, some are prepared for processing. In the production of confectionery, the main raw 121 materials include flour, sugar, butter, eggs, and additional raw materials include dairy products, fruits, berries, nuts, wine, essences, softeners, etc. All raw materials for production must meet the specified standard requirements and technical conditions, and dyes must meet the requirements of sanitary regulations. Along with this, it is necessary to properly organize the storage of raw materials. The temperature of storage rooms where dry raw materials (flour, sugar, starch) are stored should be kept at around 15 0 С and relative air humidity at around 60-65%. Perishable raw materials should be stored in conditions not higher than 5 0 С. Raw materials brought to the enterprise frozen are kept at minus temperature. They are stored in separate places so that the smell of aromatic substances, wine, and compotes does not spread to other products. Let's consider some of the additional raw materials used in the production of flour confectionery products. Honey. Natural honey is a sweet-smelling, sweet-tasting product with high nutritional value. There are natural honey flower, sap and mixed types. From 50% to 90% of the mass of flower nectar is water. Nectarine dry matter consists of sucrose, glucose, fructose, dextrins, additives, vitamins (V1, V2, V6, RR, etc.), enzymes. About 94% of the nectarine's dry matter is sugar, and the remaining 6% is accounted for by other substances. When the moisture content of the honey reaches 18-21%, the ripening of the honey ends. Honey is separated from the wax by centrifugation and in some cases by pressing. The density of honey depends on the amount of water it contains, it can be 1410-1440 kg/m3. As honey, the following requirements are set: the taste is sweet, pleasant, without foreign taste, the aroma is natural pleasant, the consistency can be creamy or crystallized. Moisture content of honey does not exceed 21%; the amount of sucrose should not exceed 7%; and the amount of glucose and fructose should not be less than 79%. It is not allowed to have mechanical impurities and signs of aging in honey. Fresh and processed fruits and berries. Fruits and berries are very important for human nutrition and industrial processing. Fruits and berries are important sources of vitamins C, R and provitamin A. Processed products of fresh fruits and berries are mainly used in the production industry of bread, pasta and confectionery products. According to their structure, fresh fruits are divided into groups with seeds, grains, berries, citrus fruits and others. A pome fruit consists of a pod, a pith, and a five-celled seed chamber containing the seeds. This group includes apples, pears, and quinces. Inside the pulp of pome fruit is a seed containing a seed. Stone fruits include cherries, plums, apricots, peaches, and reds. A large amount of them is used for drying, puree, juice, jam, jam. Depending on the structure of the berries, there are three types: true (grape, blackberry, privojnik, cranberry, cranberry, bilberry), the seeds of which are inside the core, and false (strawberry and strawberries) and are divided into complex groups (raspberries) consisting of small fruits that are joined together. 122 Citrus fruits - this group includes lemons, oranges, tangerines, grapefruits. Citrus fruits consist of peel, pith, seed, pod and calyx. The peel is thick, dense, and the fruit makes up 25-34% of the total mass. All essential oils (1.2- 2.5%), glucosides and pectin substances are paid in the skin of fruits. The peel of citrus fruits serves as a raw material for obtaining valuable essential oils and pectin. The core of these seeds consists of slices, which are used fresh and in the preparation of purees, soups, juices and sukkats. Fruits and berries are mainly used in the confectionery industry in canned form. It uses chemical sterilization, drying, freezing and other preservation methods. Dried fruits and berries are also widely used. During drying, the amount of moisture in the product is brought up to the amount (16-20%) where microorganisms cannot multiply. Due to the decrease in humidity, the concentration of dry matter in fruits and berries increases, and their solutions have an osmotic pressure that has a destructive effect on microorganisms. Dried apple powder is used in the preparation of kishmish, magiz, barkak bread products. When evaluating the quality of fruits and berries according to the requirements of standard or technical conditions, attention is paid to their color, taste, smell, shape, moisture, the amount of damaged samples, the presence of small particles, impurities. For example, let's take the pulp made from dried seeded grapes. Raisins. Raisins are used in the preparation of cakes, buns, roulettes and other products. Gives the product a unique taste and aroma. Raisins are thoroughly cleaned of impurities and other impurities before use. Cocoa beans and nuts. Cocoa beans are obtained from the seeds of the cocoa tree grown in tropical countries (America, India and the Pacific Islands) after special processing and drying. Depending on the place of cultivation, cocoa beans are divided into three groups: African and Asian cocoa beans. Cocoa beans are divided into two groups according to their quality: high quality (variety) and medium quality (consumable). The content of pure cocoa beans is fat 9% cocoa butter-more than 50%), theobremine -0.8-1.5% caffeine, carbohydrates (starch-5-9%, sugar content -1- 1.6%) ) proteins -10.3-12.5%, processing and coloring substances -4-7%, the amount of mineral substances -24-3.5%, organic acids -2%, aromatic substances, mineral It is low in salt, contains vitamins, various enzymes, etc. Nuts contain up to 70% fat, 15-25% protein, 2-3% minerals, vitamins A, C and B vitamins. In terms of energy value, they are higher than all known plant products. In the confectionery industry, nuts are valuable raw materials used in the production of high-quality candy and chocolate products, pies and cakes. Download 1.42 Mb. Do'stlaringiz bilan baham: |
