Essential Ambient Storage Terminology

FIFO (First-In, First-Out)

FIFO is an important inventory management strategy that encourages the rotation of stock by prioritising the use of older products before the newer ones. This approach mitigates the issue of food spoilage by reducing the risk of items being stored for too long. The implementation of FIFO minimises waste and ensures optimal freshness by prioritising items which are closer to their expiration dates.

Shelf-Stable Foods

Shelf-stable foods are those that can be safely stored at room temperature. Usually, this is due to their low moisture content or preservation methods. Examples of these foods include canned fruits and vegetables, dried fruits, nuts, and several kinds of packaged snacks such as crackers. Designed for ambient storage, these items have an extended shelf-life, and their nutritional value is well-preserved.

Hermetic Sealing

Hermetic sealing is a packaging technique used to construct airtight containers. By preventing the entry of air, moisture and contaminants, hermetic sealing is instrumental in preserving product integrity. Due to this airtight environment, products stored under ambient conditions have extended longevity. Factors that can degrade products such as exposure to moisture and light are kept at bay, ensuring that products remain fresh and consumable for the longest possible time.

Preserving Food Safety & Quality in Ambient Storage

Control of Microbial Growth

Managing microbial growth is a central aspect of ambient storage to avert food spoilage and contamination. High humidity stimulates the growth of mould and other spoilage organisms, hence, it is necessary to maintain relative humidity below 60%. Quality food packaging plays a substantial role in sustaining microbial integrity. Utilisation of airtight containers or vacuum sealing reduces exposure to moisture and contaminants, subsequently decreasing the risk of spoilage. Furthermore, the use of preservatives such as salt or sugar can enhance food safety by inhibiting microbial growth, although consumer preferences for fewer additives may determine the choice of preservatives.

Impact of Oxidation

Oxygen poses a significant challenge to food quality in ambient storage conditions. Its presence incites oxidation, resulting in rancidity and the development of off-flavours, notably in fatty foods like nuts and oils. Oxidation impacts more than taste, it can also impair the food’s nutritional composition. To mitigate these effects, multiple control strategies are implemented. Modified Atmosphere Packaging (MAP) is a prevalent method that substitutes ambient air in packaging with gas mixtures that diminish oxygen levels and intensify levels of carbon dioxide. This technique effectively constrains oxidation, thereby extending shelf life. Alongside MAP, the inclusion of oxygen absorbers can further limit oxygen exposure, creating a more stable storage environment for food.

Nutritional Content Degradation

The degradation of nutrients in stored foods can transpire due to multiple factors including temperature, humidity, and exposure to oxygen. For example, vitamins such as vitamin C degrade considerably at room temperature, losing their potency considerably faster than when stored under refrigeration. Effective environmental control is key; managing temperature and humidity preserves organoleptic qualities and aids in maintaining nutritional integrity over time. Innovations in packaging that block light and moisture can prevent the oxidation that typically accelerates nutrient loss. Additionally, antioxidants can be integrated into packaging materials to extend the nutritional profile of foods during storage.

Terms to Know in Food Safety & Quality Preservation

MAP: Modified Atmosphere Packaging

This approach assists in inhibiting microbial growth and enzymatic reactions, subsequently extending food shelf life and preserving its quality. MAP proves especially beneficial for a variety of products including fresh produce and ready-to-eat meals, as it prevents oxidative spoilage and sustains sensory characteristics.

aW: Water Activity

Water activity (aW) is the measure of available water in food, which is a necessity for microbial growth. Maintaining low aW values—below 0.6—inhibits microbial activity. This factor is significant for food stored in ambient conditions. Commodities such as dried fruits and cured meats are examples of food items that reap the benefits of low water activity, extending their shelf life and safety in ambient conditions.

Non-enzymatic Browning

Non-enzymatic browning in food is an outcome of chemical reactions that occur between amino acids and sugars during storage. This process can dramatically affect food quality over time. This phenomenon alters the colour, flavour and texture of foods and can be amplified by exposure to heat and light. Therefore, it is a key factor to consider in ambient storage practices. Effective management methods such as temperature control and protective packaging can assist in mitigating unappealing browning reactions.

These strategies and terminologies play a significant role in maintaining food safety and quality within ambient storage parameters, aiding in extending shelf life while preserving product integrity.
