Honey is a colloidal liquid with a high water content, making it prone to fermentation and spoilage if not properly processed. Due to the limitations in producing large quantities of mature honey, it's challenging to store and transport it effectively. As a result, advanced processing techniques are essential to enhance its shelf life and quality. Below is an improved and detailed description of the condensed honey processing technology.
Raw material honey must be carefully selected to ensure the final product meets high standards. It is crucial to test the color, aroma, moisture level, presence of honey seeds, amylase activity (a freshness indicator), collection time, and pesticide residues before proceeding. Only high-quality raw honey should be used for further processing.
The next step is melting, which involves heating the honey at 60-65°C for about 30 minutes. This process helps prevent fermentation and delays crystallization, preserving the honey’s natural properties. After melting, the honey is filtered at around 40°C to remove impurities and larger crystals. Filtration should be done in a sealed system to minimize flavor loss and reduce exposure to air.
Vacuum concentration follows, where the honey is concentrated under a vacuum of 720 mmHg and at a temperature between 40-50°C. This low-temperature method helps retain the honey’s color, aroma, and taste. During this stage, it's important to recover any volatile compounds that may be lost during heating to maintain the honey’s original flavor profile.
Once concentrated, the honey needs to be cooled quickly to avoid quality degradation. Forced circulation and stirring are often used to ensure even cooling and maintain the product’s appearance and texture. After cooling, the honey undergoes inspection, with random samples tested to confirm that the moisture content remains stable within 17.5-18%.
Packaging options include large drums or small bottles. Large containers should be lined with food-grade paint to prevent corrosion from acidic components in the honey. Small packages are typically filled into sterilized glass bottles, ensuring hygiene and freshness.
Finally, storage conditions play a vital role in maintaining honey quality. It should be stored in a cool, dry place away from direct sunlight and heat. The warehouse must be well-ventilated and free from odors that could contaminate the product. Proper storage ensures the longevity and integrity of the final concentrated honey.
