Functionality of Plant-Based Additives

Plant-based additives offer a range of functionalities in the food industry, aiming to mimic or improve the qualities provided by animal-based ingredients.

  • Flavour: Plants’ inherent diversity provides a vast array of natural flavoring. Phenolic acids, for instance, contribute sour and bitter notes, while flavonoids offer a spectrum of tastes ranging from bitter and astringent to sweet. Bio-generation techniques, leveraging microbes or enzymes, further expand the palette of natural flavors, creating novel taste profiles without resorting to synthetic ingredients.
  • Emulsification: Lecithin, a naturally occurring phospholipid in soybeans, flaxseed, and sunflower seeds, emerges as a powerful alternative to synthetic emulsifiers. Lecithin’s ability to stabilize oil-in-water mixtures is crucial for creating smooth and creamy textures in various products, from salad dressings and mayonnaise to baked goods and nut butter.
  • Colour: Vibrant colors play a significant role in consumer perception of food freshness and appeal. Plant-based additives offer a plethora of pigments that can replace synthetic food coloring. Chlorophyll, the pigment responsible for the verdant hues of leaves, can bring a vibrant green color to food products. Carotenoids, a diverse group of pigments found in fruits and vegetables, contribute a spectrum of colors ranging from yellow and orange to red. Anthocyanins, prevalent in berries and other pigmented fruits, offer a range of blue, purple, and red hues. Extracting these pigments from plant sources provides a natural and safe alternative for coloring food products.
  • Preserving Freshness Naturally: Plant extracts boast potent anti-browning and anti-texture degradation properties. Essential oils extracted from cloves and oranges exhibit remarkable effectiveness in inhibiting enzymes responsible for browning in fruits and vegetables, thus preserving their visual appeal. Similarly, essential oils derived from basil target enzymes that break down the texture of fruits and vegetables, maintaining their freshness and preventing spoilage.
  • Extending Shelf Life: Extractions from readily available plants like aloe vera, lemongrass, and neem can extend the shelf life of produce, offering a promising solution that prioritizes food safety and environmental responsibility. These extracts can slow down the spoilage process in fruits and vegetables, leading to a longer shelf life and minimizing food waste.
