I. What is Reduced Moisture Content Honey?

Reduced moisture content honey is pure honey that has been processed using a machine to lower the moisture level in honey by removing water from it. As a result, the finished honey has a much lower water content, typically around 16% to a maximum of 19%.

What is Reduced Moisture Content Honey?

Reducing the moisture content of honey aims to enhance the quality of honey, ensure its purity, and provide long-term preservation while retaining its inherent nutritional value.

The machines used to reduce honey's moisture content employ modern technology, using vacuum pressure (operating effectively without excessive heat, unlike outdated refrigeration methods that can impact honey quality). These moisture reduction machines are typically designed to be compact yet highly efficient and are used in premium honey production facilities.

II. Key Characteristics of Reduced Moisture Content Honey

Reduced moisture content honey fundamentally retains its delicious flavor, along with numerous vitamins and minerals like regular honey. However, honey with reduced moisture content through the distillation process may exhibit some distinct characteristics, such as:

• Reduced moisture content honey typically has a water content of around 16% to a maximum of 19%.
• It has a transparent color and is more attractive in appearance compared to freshly harvested honey.
• Reduced moisture content honey is less susceptible to fermentation, foaming, and spoilage, allowing for long-term preservation.
• Honey that has undergone moisture reduction is capable of resisting crystallization over extended periods when stored under appropriate conditions and is less likely to become sour or undergo detrimental changes in quality.
• Reduced moisture content honey is thicker, has a delicious flavor, and meets high-quality standards, even for export.

III. How does moisture content affect honey quality?

How does the moisture content in honey affect its quality?

The moisture content in honey significantly affects its quality. The purer the honey, the thicker and higher the quality. Therefore, honey with a high water content is undesirable.

High water content in honey indicates lower quality. Honey with high water content is prone to fermentation, foaming, and spoilage, making it less appealing. Especially when stored at high temperatures, honey with high water content can foam or release gas due to the fermentation process.

Reduced moisture content honey is one of the criteria for evaluating delicious honey and its long-term preservation capabilities without altering its composition. Most honey products from large companies nowadays undergo moisture reduction processes.

IV. Principles of honey hydration reduction?

Natural honey, when harvested, typically contains a water content ranging from about 21% to 25%, depending on the type of honey and the time of harvest. The water content in honey can vary.

The principle of reducing the moisture content of honey through a hydration reduction process

The more water honey contains, the thinner it is, making it prone to foaming, fermentation, and even souring. If not carefully preserved, honey with high water content can easily spoil. That's why professional honey producers have considered using machines to separate water from honey, making it denser and easier to preserve for an extended period.

Under normal atmospheric pressure conditions (760mmHg), honey absorbs moisture. Water can evaporate from honey at temperatures below 10 degrees Celsius. Under these conditions, two distinct parts can be obtained: water and pure honey.

Pure honey, after water separation, ensures a water content of only 16-19%, meeting export standards and maintaining high quality for packaging and sale in the market.

1. The honey hydration reduction process

Industrial honey factories are equipped with modern equipment and adhere to strict processes that include the hydration reduction phase to produce high-quality honey products meeting stringent criteria for safety and export.

The honey hydration reduction process is carried out in the following steps:

The process of processing diluted honey

• Step 1: After harvesting, honey is filtered to remove any impurities, such as pollen, bee parts, wax, and more.
• Step 2: Hydration reduction is carried out to separate water from honey. Honey is placed into a modern hydration reduction machine under negative pressure conditions to initiate the hydration reduction process.
• Step 3: Product packaging and labeling. After undergoing initial processing and hydration reduction, honey's quality is checked. If it meets quality standards, it is packaged, labeled, and sent to the market for sale.

2. What is the typical water content in Vietnamese honey?

Vietnam has a tropical monsoon climate with heavy rainfall during the rainy season, resulting in relatively high water content in Vietnamese honey, which can exceed 24%. This high water content can lead to honey fermenting and losing its original flavor if not properly stored.

Additionally, honey can absorb moisture from the air, so if the honey container is not sealed tightly, the water content in honey can increase over time. To accurately measure the water content in honey, a refractometer is often used.

3. Is there a significant difference in water content between Vietnamese honey and foreign (Italian) honey produced in Vietnam when both are harvested at the same time?

The water content in honey is primarily determined by climate conditions and the type of flower pollen collected by bees to make honey, rather than the bee species. Therefore, when honey is produced under the same conditions in Vietnam, whether by local bees or imported Italian bees, the water content is expected to be similar.

4. Distinguishing between hydration-reduced honey and regular ripened honey?

Hydration-reduced honey and regular ripened honey are two distinct types of honey that can be distinguished as follows:

Ripe Honey

Ripe honey is the result of bees diligently collecting pollen and refining honey until it reaches full maturity, fragrance, and flavor:

• This honey is typically harvested when it is fully ripe.
• It contains a higher percentage of water, along with impurities like pollen, bee parts, and foreign matter. Ripe honey can foam easily at high temperatures.
• When you open a jar of ripe honey, it releases a strong and distinct aroma, and you can see honeycomb particles and air bubbles rising to the surface quickly.
• Ripe honey dissolves quickly when mixed with water, but in cold water, it may form crystals or become cloudy, especially in winter.
• Ripe honey can become crystallized or granulated over time, but this is a natural process and does not affect its quality. In fact, in some European countries, crystallized honey is preferred for its unique texture and flavor.

Hydration-Reduced Honey

Hydration-reduced honey is a type of honey that has undergone industrial processing, with water removed to ensure the highest purity. In essence, hydration-reduced honey is essentially natural honey or honey from ripened combs that have gone through a process to remove water, resulting in the following characteristics:

• Thick consistency with a beautiful color, smooth texture, and no gas bubbles on the surface.
• When you open the honey container, you won't notice any gas escaping, and when you tilt the container, the honey moves slowly with a visible honeycomb and air bubbles rising very slowly.
• When you mix this honey with water, it doesn't dissolve immediately because hydration-reduced honey has a thick consistency. You need to stir it to make it dissolve. However, if you mix it with ice water, it will dissolve very slowly, or even form clumps.
• Hydration-reduced honey has a mild aroma, but when heated, it releases a distinctive and highly enticing fragrance.
• When stored in a refrigerator or under low-temperature environmental conditions, such as during the winter in northern Vietnam, the honey becomes thick and somewhat crystallized.
• It has a longer shelf life and doesn't ferment or become sour as easily as untreated, raw honey.

V. Why does hydration-reduced honey tend to crystallize?

Mật ong bị kết tinh và đóng đường là hiện tượng mật ong chuyển từ dạng lỏng sang thành các hạt theo dạng kết tinh ở dưới đáy chai, miệng chai hoặc kết tinh từ đáy lên đến giữa chai. Phần mật ong kết tinh nhìn bằng mắt thường sẽ gần giống như mỡ lợn.

The reason hydration-reduced honey tends to crystallize is due to its chemical composition

According to chemical analysis, honey consists of approximately 70% sugars and various vitamins. Among these sugars, there is approximately 38.5% fructose and 31% glucose. Additionally, glucose easily separates from water and transforms into crystals, causing honey from bees in liquid form to gradually become smoother, eventually transitioning into granules.

After undergoing the hydronation process, the water content in honey is significantly lower than initially. Under normal conditions, the viscosity of honey can reach over 80%.

Therefore, once hydronated, the high glucose content, which can reach between 40-45%, leads to the rapid formation and appearance of crystalline granules when the sugar in honey becomes saturated. This is the primary reason why hydronated honey often crystallizes.

However, it's important to note that the phenomenon of honey crystallization and granulation is entirely natural and does not negatively impact the quality of honey. In fact, in many European countries, crystallized honey is highly favored because it is believed that the crystalline portion of honey, when spread on food, enhances its flavor and aroma.

VI.  Should you choose to purchase hydronated honey?

Compared to natural wild honey collected and harvested by individuals without any processing, hydronated honey guarantees superior quality for several reasons:

• Hydronated honey has undergone industrial processing, including thorough filtration to remove all impurities such as pollen, bee parts, debris, and dust, ensuring compliance with food safety and hygiene standards.
• Hydronated honey has a low water content, making it highly viscous and aromatic. It can be stored for extended periods without undergoing fermentation or turning sour, unlike untreated raw honey.
