Use of green tea for the production of sponge cake

The problem of micronutrient enrichment and the improvement of the technology for the production of flour confectionery products is relevant. The aim of the work is to study the possibility of using green tea to create sponge cake. The objects of study were Sencha green tea powders (Japan and China), wheat flour, their mixtures in different percentages and sponge cake. According to the obtained experimental data green tea powders is characterized by low humidity (5.0 ± 0.5) % and high acidity (5.8 ± 0.2) %. The content of flavonoids in tea is (52.5 ± 0.5) mg/100 g, the amount of β-carotene - (3.2 ± 0.5) mg/100 g. The following physical-chemical and technological parameters were determined in the finished products: moisture, porosity and swelling. Rheological characteristics of finished products were determined by the device “Structure meter ST-1M”. During storage of products the dynamics of microbiological indicators and water activity over 10 days was determined. The results objectively proved the possibility of using green tea for the production of flour confectionary products. Finished products had high organoleptic and rheological properties. The use of green tea enriched the product with phosphorus, iron, β-carotene and B vitamins

Food Engineering of Meat Bio-Products to Immunity Strengthening

The mainstream of healthy nutrition during the new coronavirus pandemic is adequate and balanced nutrition based on strengthening human immunity. The authors consider the main aspects of developing theory and practice of adequate nutrition using innovative biotechnologies. Based on the St. Petersburg startup GASTROMAN.LAB there was developed new line of Bio-products enriched with probiotic cultures of microorganisms, biologically active substances of plants and prebiotics that was implemented using modern technological methods of food engineering. The recipes of original meat products of the Petersburg cuisine were used as basis for new developed recipes of bio-culinary products
