Аннотация

This work explores the application of the Harrington desirability function method in the food industry, emphasizing its role inoptimizing multiple quality parameters simultaneously. The method enables food technologists to assess and balance sensory, nutritional, and safety attributes effectively. It is widely applied in product formulation, process optimization, packaging, and quality control. By converting complex, multidimensional data into a single desirability value, the Harrington method supports efficient decision-making and enhances product development. The paper highlights recent studies and practical applications, underlining its growing relevance in ensuring consistent quality and consumer satisfaction in modern food production systems.

The Harrington method (Harrington desirability method) is widely used in the food industry to assess the complex quality of products and processes. This method allows transforming different indicators (e.g. organoleptic, physicochemical, microbiological) into a singledimensionless desirability scale, which facilitates decision making. Application intheFood industry : 1. Evaluation of the quality of raw materials and products - the method allows considering several criteria at once, such as taste, smell, texture, moisturecontent, acidity, etc. 2. Optimization of technological processes - used to select the best processing modes (heattreatment, drying,fermentation, etc.). 3. Development of new products - helps to evaluate consumer satisfaction and adjust recipes. 4. Food safety control - allows you to take into account microbiological indicators and othersafety parameters. 5. Optimization of technological processes – used to select the best processing modes (heat treatment, drying, fermentation, etc.). 6. Development of new products – helps to evaluate consumer satisfaction and adjust recipes. 7. Food safety control – allows to take into account microbiological indicators and other safety parameters. The Harrington desirability function method is a well-established multi-criteria decision-making tool that has gained increasing relevance in various industrial sectors, including the food industry. This method is particularly important where product quality depends on multiple parameters that need to be optimized simultaneously. As food production processes become more complex and consumer demands for quality, safety, and sustainability increase, the application of the Harrington method provides a systematic, quantitative framework for evaluating and optimizing product and process variables. http://www.internationaljournal.co.in/index.php/jasass 544 Volume15Issue04, April2025 Impact factor: 2019: 4.679 2020: 5.015 2021: 5.436, 2022: 5.242, 2023: 6.995, 2024 7.75 In the food industry, product quality is not defined by a single parameter but by a combination of attributes such as taste, texture, color, nutritional content, shelf life, and safety. Often, optimizing one characteristic may negatively affect another. For example, increasing shelf life may require preservatives that can impact taste or texture. The Harrington method is highly relevant in these situations because it transforms multiple quality characteristics into a single desirability value. This transformation allows producers to assess overall product acceptability andmake informed decisions regarding process parameters orformulation changes. A key advantage of the Harrington method in food processing is its ability to handle both subjective and objective criteria. For instance, sensory attributes such as flavor or aroma—often evaluated by trained panels or consumers—can be incorporated alongside objective laboratory measurements like pH, moisture content, or microbial counts. By assigning desirability functions to each characteristic, producers can optimize multiple goals simultaneously, improvingoverall product quality and consumer satisfaction. Another area where the Harrington method is highly applicable is in quality control and standardization. Food manufacturing facilities are required to maintain consistent quality across large batches of products. Variations in raw materials, equipment performance, or environmental conditions can introduce inconsistencies. By applying the Harrington method, food scientists and engineers can identify optimal operating conditions that yield consistently high-qualityproducts whilereducing variability. Furthermore, the Harrington method is useful in new product development (NPD), where multiple prototypes must be evaluated based on various performance indicators. During this process, the method helps to select the best formulation that meets desired levels of nutritional value, sensory appeal, cost-effectiveness, and regulatory compliance. It enables the efficient screening
