Project Overview

The project topic, "Application of High Pressure Processing (HPP) Technology in Extending Shelf Life of Dairy Products," focuses on the utilization of High Pressure Processing (HPP) technology to enhance the shelf life of dairy products. This research aims to investigate the effectiveness and feasibility of applying HPP technology as a novel method in the preservation and quality maintenance of dairy items. Dairy products are highly perishable due to their nutrient-rich composition and susceptibility to microbial contamination, leading to a shorter shelf life compared to other food categories. High Pressure Processing is a non-thermal preservation technique that involves subjecting food products to high levels of hydrostatic pressure, which can reach up to 600 MPa. The application of high pressure has been proven to inactivate microorganisms, enzymes, and spoilage agents, thereby extending the shelf life of perishable foods while retaining their nutritional value and sensory attributes. In the context of dairy products, such as milk, cheese, and yogurt, the implementation of HPP technology offers a promising solution to address the challenges associated with product spoilage and quality degradation. By exploring the potential of HPP technology in dairy product preservation, this research seeks to contribute to the enhancement of food safety, quality, and consumer satisfaction. The study will involve conducting experiments to assess the impact of high pressure on the microbial load, enzymatic activity, and overall quality parameters of various dairy products. Additionally, the research will evaluate the sensory characteristics, nutritional content, and storage stability of HPP-treated dairy items to determine the effectiveness of this preservation method in prolonging shelf life. Furthermore, the project will address the practical implications and economic feasibility of implementing HPP technology in the dairy industry. By analyzing the cost-effectiveness, scalability, and regulatory considerations associated with HPP processing, this research aims to provide valuable insights for food manufacturers, policymakers, and stakeholders in the dairy sector. Ultimately, the findings of this study are expected to contribute to the development of innovative preservation strategies for dairy products, promoting sustainability, food security, and market competitiveness in the food industry.
