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.
