Flow Chart:

Technology:
Guanjie Biotech uses spray drying technology. During spray drying, the bitter melon fruit is processed into a slurry material. It is then sprayed into hot air through a spray dryer. This process removes most of the water quickly to prepare bitter melon powder. In this process, processing parameters need to be strictly controlled to ensure the quality and uniformity of bitter melon powder. Such as spray pressure, spray angle, drying temperature and so on.
Bulk Bitter Melon Powder has high bioavailability and strong stability. Because of its low moisture content, it can be stored for a long time.
Testing:
We insist on producing high quality products. For Spray Dried Bitter Gourd Powder, we carry out a little test on bitter gourd powder.
• Appearance test
The appearance of bitter melon powder should be light yellow or yellowish green. It has obvious bitter melon flavor, powdery, no visible impurities, no lumps. The particles of bitter melon powder should be full, uniform, short fibrous and free of foreign matter. Appearance detection can be carried out by observation and smell.
• Color and luster detection
The color of bitter melon powder should appear light yellow or yellowish green. The color is uniform and consistent without color difference. The depth of its color should be consistent with the standard product, and there should be no obvious difference in depth or color difference. Color detection can be measured by colorimeter.
• Odor detection
Bulk bitter melon powder has a unique bitter taste and fragrance, no odor or smell. The odor of bitter melon powder is determined by its internal composition, if it is not properly preserved or damp, it may have peculiar taste or smell. The odor test can be carried out by sniffing and comparing with standard products.
• Taste test
The taste of bitter melon powder should have a certain chewiness and bitterness, with no off-flavor or off-smell. The taste of bitter melon powder is related to its processing technology and preservation method, if it is not properly preserved or damp, its taste may be affected. Taste test can be done by sampling.

• Moisture Test
The moisture content should be controlled within a certain range, generally 8% to 12%. Excessive moisture will cause the bitter melon powder to be easy to be damp and spoiled, while too low will affect its taste and nutritional value. Moisture detection can be measured by drying method or infrared meter.
• Ash Detection
The ash content of bulk bitter melon powder should be controlled within a certain range, generally 3% to 5%. Too high ash indicates that the bitter melon powder has more impurities, too low may affect its nutritional value. Ash detection can be measured by ashing method.
• Protein Detection
Bitter melon powder contains a certain amount of protein, usually 3% to 5%. Too low a protein content may affect its nutritional value, while too high a content may indicate that other substances have been added to the bitter melon powder. Protein test can be measured by Kjeldahl method.
• Dietary fiber test
Bulk Bitter Melon Powder is rich in dietary fiber, which plays an important role in human health. If the dietary fiber content is too low, it will affect its nutritional value; if it is too high, it may indicate that other substances have been added to the bitter melon powder. Dietary fiber can be measured by washing method or enzyme weight method.
• Pesticide Residue Test
Pesticide testing of bitter melon powder is very important because bitter melon may be contaminated by a variety of pesticides during the growth process. Common pesticide detection methods include gas chromatography (GC), high performance liquid chromatography (HPLC) and gas chromatography-mass spectrometry (GC-MS). These methods can detect the presence of various pesticide residues such as organophosphorus, organochlorine, pyrethroids, etc. and their levels in bitter melon powder.
How To Choose Best Bitter Melon Powder?
1. Color:
Good bitter melon powder should be light yellow or yellowish green in color. If the color is too white or yellowish, it may be the result of removing too much or too little of the bitter melon scoop during processing, or the quality of the raw materials may be poor.
2. Odor:
High quality bitter melon powder smells faintly bitter melon flavor. If the smell is too strong, it may be that the bitter melon scoop is removed too much, resulting in too much bitter flavor. If there are other off-flavors, it may be that artificial flavors and other substances have been added during processing.

3. Texture:
It should be in the form of bulk Bitter Melon Powder without impurities and granularity. If the texture is rough, it may be that the quality of raw materials is not good, or the processing technology is not fine enough.
4. Solubility:
Take a small amount of bitter melon bulk powder into the water, the real should be able to dissolve quickly. If it can not be dissolved or dissolved slowly, it may be added other substances.
5. Taste:
Take a small amount and put it into your mouth to taste. It should have a light bitter melon flavor. If it has a sweet taste or other off-flavors, other substances may have been added.
