Create a complete university lecture presentation from this PDF. IMPORTANT: * Do NOT summarize the content. * Do NOT omit, delete, or simplify any scientific information. * Preserve ALL definitions, explanations, scientific facts, values, tables, classifications, examples, and details from the original PDF. * Every important detail must appear on the slides themselves, NOT only in speaker notes. * If a slide contains too much information, split it into 2 or more slides instead of reducing the font size. * Use large, highly readable fonts suitable for a university lecture hall. * Keep all scientific terminology accurate and unchanged. * Organize the information into a logical teaching sequence. DESIGN: * Create a modern, professional university-level scientific presentation. * Use clean academic layouts with strong visual hierarchy. * Add relevant realistic 3D scientific illustrations, diagrams, icons, and visual explanations related to milk hygiene and dairy science. * Use enlarged, sharp, easy-to-understand scientific visuals. * Do NOT replace scientific content with decorative images. * Make the PowerPoint fully editable. OUTPUT: * Create an editable PowerPoint presentation (.PPTX). * Prioritize complete content preservation over having fewer slides. * The final presentation should be suitable for teaching students in a lecture hall.
