    Study Notes

    Response Surface Methodology

    • Predictive models generate contours and response surfaces within an experimental range.
    • A response surface plot shows the relationship between the response and independent variables in 3D.
    • Contour plots display ellipses or circles, indicating a maximum or minimum response.
    • Hyperbolic or parabolic contours indicate a saddle point, neither maximum nor minimum.
    • Contour plots show estimated responses and the general nature of the system.
    • Optimum points may vary depending on the direction of travel from the central point.

    Formulation Design

    • Start by finding and modifying existing formulations.
    • Convert volume measurements to weights and calculate percent by weight.
    • Take notes and record observations during production and product evaluation.
    • Determine which formulation and process worked best.
    • Identify variables that require adjustment to reach the optimal product.
    • Prioritize variables based on effectiveness and cost.
    • Test one variable at a time, making only one change per experiment.
    • When adding a new ingredient, test the highest usage level first.
    • Addition adds new functionality without affecting existing ingredients' percentages.
    • Substitution replaces one or more ingredients with another, keeping other percentages consistent.
    • Decide between addition and substitution based on the new ingredient's functionality.
    • Keep track of material balance throughout the process.
    • Track moisture content to understand changes in product characteristics and for nutrition label accuracy.

    Why Convert a Recipe into a Formula?

    • Consistent Quality: Weighing ingredients ensures consistent results, eliminating variability in measurements.
    • Scalability: Formulas allow adjustments in quantities, facilitating scaling up or down without compromising product integrity.
    • Cost-Effectiveness: Weighing ingredients provides precise cost control for unit costs, COGS, and product margins.
    • Automation: Formulas facilitate automated food processing, ensuring efficiency and reducing errors.
    • Standardization: Formulas provide standardized instructions for consistent product quality and regulatory compliance.
    • Product Labeling: Consistent ingredient quantities support accurate nutritional information and label compliance.
