Food Preservatives are Raising the Awareness of Extra Waste

Introduction

According to Food Preservatives Statistics, Food preservatives are substances incorporated into food products to extend their shelf life by hindering the growth of microorganisms and averting oxidation. They are categorized into two primary groups: natural, such as salt and sugar, and synthetic, like benzoates and sulfites.

These inclusions are vital for preventing food spoilage, maintaining freshness, and ensuring compliance with safety regulations. Their utilization is overseen by governmental bodies, and they are commonly present in a broad assortment of food items, spanning from baked goods to beverages and processed meats.

Despite rising concerns regarding the potential health effects of synthetic preservatives, there is a growing consumer inclination toward natural options. However, grasping the fundamentals of food preservatives remains imperative for upholding the quality and safety of food within the industry.

History of Food Preservation

• In the early 1800s, amid the Napoleonic Wars, a pivotal exploration into food preservation commenced.
• This was prompted by the realization that salt-preserved meats lacked sufficient nutritional value and the alarming occurrence of scurvy among soldiers and sailors.
• French chemist Nicolas Appert made a groundbreaking discovery during this time: he found that subjecting food to heat in tightly sealed containers effectively preserved it.
• This breakthrough marked a significant advancement in food preservation techniques.

Examples of Natural Food Preservatives

Rosemary Extract

• The specified ingredients include rosemary extract, rosemary acid, and rosemary oil, with varying specifications of rosemary acid content ranging from 5% to 30% to 98%.
• These components are typically found in the form of fine brown powder.
• Known for their efficacy as food antioxidants, rosemary-derived compounds serve as natural preservatives, effectively inhibiting oxidative processes that lead to food spoilage.

Forsythia Extract

• Forsythia, an herb commonly used in traditional Chinese medicine, possesses antibacterial properties that inhibit the growth of various bacteria, making it a suitable natural preservative.
• Forsythia extract demonstrates inhibitory effects on both Gram-positive and Gram-negative bacteria, effectively prolonging the shelf life of food products.
• Its antibacterial components, primarily forsythia phenol, contribute to its efficacy in food preservation.

Garlic Extract Allicin

• Garlic, known for its allicin content, exhibits potent inhibitory and lethal effects on dysentery bacilli, certain pathogenic intestinal bacteria, and common food spoilage fungi, rendering it a natural preservative.
• While garlic’s antibacterial properties are relatively mild, its stems and leaves demonstrate significant antibacterial activity.
• However, these antibacterial properties diminish significantly at high temperatures, with the optimal temperature for garlic extract preservation being below 85°C.

Clove Oil

• Clove is rich in compounds like eugenol and tannin.
• Research indicates that clove oil possesses a wide-ranging antibacterial effect, notably against Staphylococcus aureus, Escherichia coli, yeast, and Aspergillus Niger commonly found in food.
• Remarkably, clove oil maintains its antibacterial efficacy even at high temperatures of up to 100°C.
• Its most notable characteristic is its potent antifungal properties, making it effective in inhibiting fungal growth.

Chitosan

• Chitosan, also known as chitin, is a polysaccharide derived from sources like crab, shrimp, and insects through chitin deacetylation.
• It exhibits potent inhibitory effects against bacteria such as E. coli, common Proteus, Bacillus subtilis, and Staphylococcus aureus while preserving the natural flavor of food.
• Widely utilized in pickled foods, raw noodles, rice, bean paste, seasonings, and fresh strawberries, chitosan serves as a natural preservative in various food products.

Synthetic Food Preservatives

Sulfur dioxide

• Sulfur dioxide (SO2) is effective against yeast and mold, altering cellular metabolic processes and enzymatic systems.
• Despite its advantages such as antioxidant properties and color preservation, its strong odor and corrosiveness limit its use in canning.
