BIOLOGICAL METHODS FOR FOOD PROCESSING Three fermentations: Lactic milk 1.5-1.8% (Cabbage, cucu*bers, dairy) Alcoholic - natural alcohol concentration 18-21 (Sach. Bayan*s)% vol. Propyion - propionic acid - bread (fermentation of the dough) Cucu*bers - (4% ss) - needed flood. They are poor in fermentation substrates. The yield of lactic acid smaller than cabbage, less durable Cabbage Thickening food. Evaporation - always at boiling point, Drying - at lower temperatures from boiling. Objective - thickening and consolidation. Eg sugar production: beetroot extract - 14% sugar - density = Labyrinth crystal substances - reduce the boiling point .... Compaction by evaporation of water. DRAINING - water removal. Evaporation. Drying. HHP - hydrostatic pressure. Center for High Pressure Autoclaves - 0.2 MPa. Homogenization - unification, eg. Breaking of fat globules - emulsion production (so that ba*ls do not swim). Piston pump - (small st*oke) - 20- 30 MPa (hydraulic system - liquid compression) Juice presses (pulp) - 1.5-2.5 MPa Screw presses for oils - up to 15 MPa in weight ... MEMBRANE PROCESSES FILTRATION - separation of particles on the partition Barriers - membranes having the properties of semi-permeable membrane FILTRATION - separation of the suspension KLAROWANIE: Broadening the use of clarifying agents (tannins, gelatin, bentonites) The most common method of clarifying is filtration. Filtration goals: Separating the suspension. Getting the liquid phase FILTRATION If too much sediment - large resistance of the filtration layer For more ... RADIATION M ESTABLISHMENT STAGES OF FOOD Small doses can cause fixation. Cold sterilization - sterilization = application of radiation 1 gray (Gy) - energy 1 J pas*ed to the body weighing 1 kg 1 rads - 0.01 Gy Radiation for food purposes: Mainly for potatoes - that they would not germinate For strawberries, onions - not moldy Destruction insects ...
