Introduction

Spoilage of food products is a widespread issue that results in significant economic losses and poses potential health risks to consumers. The spoilage process is primarily driven by the activities of microorganisms, such as bacteria, yeasts, and molds, which can grow and multiply rapidly in food if the right conditions are present. However, the microbial interactions that occur within a food system play a critical role in determining the rate and extent of spoilage. Understanding the competitive dynamics between these microorganisms is essential for devising effective strategies to control spoilage and extend the shelf life of food products. Microorganisms in food systems compete for limited resources such as nutrients, water, and space. When resources are scarce, certain microorganisms may outcompete others, gaining an advantage in growth and survival. This competitive advantage can influence the composition of the microbial community and, consequently, the rate of food spoilage [1, 2].

In some cases, microorganisms can work together in a synergistic manner, enhancing each other's growth and metabolic activities. For instance, some bacteria produce enzymes that break down complex food components into simpler forms, making them more accessible to other microorganisms. This cooperation can lead to accelerated spoilage as the microbial community becomes more diverse and capable of utilizing a wider range of nutrients. On the other hand, certain microorganisms may exhibit antagonistic behavior by producing antimicrobial substances, such as bacteriocins or organic acids that inhibit the growth of competing microorganisms. This antagonistic interaction can act as a natural defence mechanism, limiting the spread of spoilage-causing microbes and prolonging the shelf life of food products [3, 4].

Some microorganisms act as predators, consuming other microorganisms as a source of nutrients. Similarly, parasitic interactions can occur where one microorganism benefits at the expense of another, leading to the decline of the host microorganism. These interactions can have a significant impact on the overall stability and composition of the microbial community in food systems. Understanding microbial interactions in food systems is crucial for developing effective food preservation strategies. Instead of targeting single spoilage microorganisms, a broader approach involves understanding the entire microbial community in a food product. By manipulating the microbiota through probiotics or the use of competitive starter cultures, the growth of spoilage-causing microorganisms can be suppressed, leading to improved food preservation [5, 6].

Hurdle technology involves combining multiple preservation factors, such as temperature, pH, and preservatives, to create an environment that is unfavourable for the growth of spoilage microorganisms. Understanding microbial interactions allows for the strategic design of hurdles to target specific microbial groups effectively. Beneficial microorganisms with antagonistic properties can be used as biocontrol agents to inhibit the growth of spoilage-causing microbes. These natural antagonists can offer a sustainable and eco-friendly approach to preserving food products. Controlled fermentation, involving the growth of desirable microorganisms, can alter the microbial ecosystem in food products, making them less susceptible to spoilage. Fermented foods often have a longer shelf life due to the presence of beneficial bacteria that produce antimicrobial compounds [7, 8].

Microbial interactions play a central role in the spoilage of food products. The competitive dynamics, synergism, antagonism, predation, and parasitism between microorganisms influence the stability and composition of the microbial community in food systems. Understanding these interactions is essential for developing effective food preservation strategies that can extend the shelf life of products and reduce economic losses. By harnessing beneficial microbial interactions and employing novel preservation methods based on the understanding of competitive dynamics, the food industry can enhance food safety, reduce waste, and meet the increasing demand for sustainable and quality food products. Further research into microbial interactions and their influence on food spoilage will continue to contribute to advancements in food preservation and the development of innovative food products. Microbial interactions in food systems are complex and multifaceted, significantly influencing food spoilage and shelf life. Understanding the competitive dynamics, synergism, antagonism, predation, and parasitism among microorganisms opens new avenues for improving food preservation and reducing waste [9,10].
