Outline the typical content of the "Results obtained" section for a biotechnology project on milk to yogurt transformation, focusing on microbiological and physicochemical analyses.

Here's what would typically be included in the "Results obtained" section for your biotechnology project on milk to yogurt transformation:

• 9. Results obtained

  This section would present the data collected from your experiments, often in tables, graphs, or descriptive text. Since no actual experimental data has been generated yet, this outlines the types of results you would report:

  • a. Microbiological Analysis Results:

    • Viable Cell Counts of Starter Cultures: Data showing the colony-forming units (CFU/mL) for Lactobacillus bulgaricus and Streptococcus thermophilus at different fermentation temperatures and starter culture concentrations. This would include initial counts, counts at the end of fermentation, and counts during refrigerated storage to assess viability and shelf life.
    • Survival Rates: Percentage survival of probiotic strains over the storage period.

  • b. Physicochemical Properties:

    • pH Values: Measurements of pH at different stages of fermentation (e.g., initial, hourly intervals, final) and during refrigerated storage.
    • Titratable Acidity (TA): Values expressed as percentage lactic acid, measured at the end of fermentation and during storage.
    • Viscosity: Measurements of the yoghurt's thickness or consistency, typically in centipoise (cP) or mPa·s, under various experimental conditions.

  • c. Sensory Evaluation Results:

    • Sensory Scores: Data from a sensory panel evaluating attributes such as taste, aroma, texture, appearance, and overall acceptability of the yoghurt samples produced under different conditions. This might be presented as mean scores on a hedonic scale.

  • d. Nutritional Composition:

    • Proximate Analysis: Data on the protein, fat, and lactose content of the raw milk and the final yoghurt product, showing any changes due to fermentation.
