Nata de coco is a popular topping in many refreshing drinks thanks to its chewy, crunchy texture and light sweetness. Many people still wonder what it’s made of and how to prepare this coconut jelly at home to achieve the same bite. This article shares a simple method you can try at home and explains how the chewy coconut topping is produced on an industrial scale.

1. What is nata de coco?

Nata de coco is a product made through the fermentation of mature coconut water using the bacterium Acetobacter xylinum. During fermentation, the bacteria convert the natural sugars in coconut water into cellulose, forming a translucent white jelly with a firm, chewy, and slightly crunchy texture.

After harvesting, the jelly layer is washed several times to remove impurities, then cut into small cubes and cooked in sugar syrup to create a light, pleasant sweetness. In industrial production, the product is further filled into containers and pasteurized before being distributed to the market.

Thanks to its crisp, chewy texture and refreshing taste, nata de coco has become a popular topping in many modern beverages and desserts. Today, it is commonly found in many popular drinks and desserts among young consumers, including bubble tea, yogurt, and traditional sweet soups.

2. What is nata de coco made from?

The key ingredient in nata de coco is mature coconut water, which makes up the largest portion of the mixture. To better understand what this coconut jelly is made of, refer to the basic ingredients list below.

Ingredient	Role
Mature coconut water	The main ingredient used for fermentation
Sugar	Provides nutrients for the bacteria
Acetic acid	Adjusts the pH of the fermentation environment
Ammonium sulfate	Supplies nitrogen for microbial growth
Acetobacter xylinum bacteria	Converts natural sugars in coconut water into the jelly layer

After a fermentation period of about 7 - 14 days, the cellulose fibers gradually bind together and accumulate into a thick, opaque white layer that forms on the surface of the liquid. This product is known as raw nata de coco, which typically has a cloudy white color and a strong sour taste due to the fermentation process.

3. Nutritional value of nata de coco

Nata de coco has long been a favorite among consumers thanks to its pleasantly chewy texture and the nutritional benefits it offers, including:

Low in calories: On average, 100 g of nata de coco contains about 92 kcal, depending on the amount of sugar added during processing.
High in dietary fiber: The jelly is formed from natural cellulose fibers created during fermentation. These fibers help support bowel movements, promote digestive health, and help you feel full for longer.
Virtually fat-free: Nata de coco contains little to no fat, making it suitable for people who are dieting or following a healthier eating plan.
Low natural sugar: In its raw form, this coconut jelly has almost no natural sweetness. The sweetness in most commercial products mainly comes from syrup or sugar solution added during processing. Because of this, consumers can better control their sugar intake by choosing raw or unsweetened coconut jelly.

Eating nata de coco in the right way can help support digestion and assist with weight management.

4. How to make nata de coco at home

4.1 Ingredients for making nata de coco

To make this coconut jelly at home, you first need to prepare all the necessary ingredients and follow the proper fermentation process to cultivate the jelly.

Ingredient	Quantity
Coconut water	4 liters
White granulated sugar	200 g
Kombucha starter liquid	400 g

4.2 How to make white coconut jelly at home

4.2.1 Step 1: Prepare the fermentation mixture

Dissolve the ingredients completely, including coconut water, sugar, and the starter liquid (kombucha), according to the prepared ratio. Then pour the mixture into a clean glass jar or container, ensuring it is well sanitized, to start the fermentation process under stable conditions.

4.2.2 Step 2: Store it properly

Cover the mouth of the jar with a thin cloth or a clean towel to keep out dust and insects. However, do not seal the jar tightly, as the microorganisms in the mixture need airflow to carry out the fermentation process.

4.2.3 Step 3: Monitor the jelly layer formation

Place the jar in a cool, well-ventilated area, away from direct sunlight, and avoid moving it too often. After about 3 - 4 days, a thin jelly layer will gradually begin to form on the surface of the liquid.

4.2.4 Step 4: Feed and maintain the culture

To help the jelly layer grow thicker and firmer, you can add more nutrients to the culture. Mix 1 liter of coconut water with 50 g of sugar, then gently move the jelly layer slightly to one side and pour the new liquid into the jar.

Note: Avoid pouring the liquid directly onto the forming jelly surface, as this may disturb or damage the structure of the developing layer.

4.2.5 Step 5: Harvest the final product

After about 10 days, you can harvest the raw coconut jelly layer, which typically reaches a thickness of around 1.5 cm. If you prefer a thicker layer, you can continue the fermentation process until around day 15 before harvesting.

This nata de coco recipe is shared by the GC Food team, a company specializing in the production and distribution of Ben Tre coconut jelly that meets international quality standards.

5. Common mistakes when making coconut jelly at home

5.1 Using the wrong fermentation container

If you use plastic jars or containers made from stainless steel or other metals, the jelly may not develop properly or fail to form into a solid layer. For better results, it is recommended to use ceramic, porcelain, or glass containers, which create a more suitable environment for fermentation.

5.2 Sealing the container too tightly

Many people worry about dust or insects getting into the fermentation liquid, so they tightly seal the jar. However, the fermentation process requires oxygen for the bacteria to function properly. If the container is sealed, the lack of airflow can kill the bacteria and prevent the jelly layer from forming. Instead, simply cover the jar with a thin cloth or clean towel to keep out dust while still allowing proper ventilation.

5.3 Not removing the sour taste of raw jelly

After fermentation, raw coconut jelly usually has a very strong sour taste, similar to vinegar. If you simply rinse it lightly and cook it with rock sugar right away, the final product may still have a strong smell and an unpleasant sour flavor.

To avoid this, the raw jelly needs to be prepared properly by rinsing it several times with clean water while gently squeezing and pressing to remove the sour liquid. After that, blanch the jelly in boiling water for about 5 minutes to help eliminate the acidic smell before continuing with the next processing step.

Rinsing thoroughly and briefly blanching raw coconut jelly helps remove its strong sour taste

5.4 Pouring coconut water directly onto the jelly surface

If you pour fresh coconut water directly onto the forming layer during the feeding process, the cellulose structure may be disrupted. As a result, the bonding process of the jelly can be interrupted, preventing the layer from thickening properly over time.

Instead, use a clean spoon to gently move the jelly layer slightly to one side before pouring the sweetened coconut water into the space. This allows the new liquid to slowly blend with the existing mixture without disturbing the delicate layer forming on the surface.

6. Industrial nata de coco production process at GC Food

The nata de coco production process at G.C Food Joint Stock Company (GC Food) follows a closed supply chain, from raw material selection to final packaging and distribution.

Step 1: Inoculation and fermentation

After harvesting, mature coconut water is pasteurized and inoculated with Acetobacter xylinum bacteria. Under strictly controlled temperature and pH conditions, the bacteria convert natural sugars into a layer of cellulose. After about 7 - 10 days, a thick white jelly layer forms on the surface and is ready for harvesting.

Step 2: Shaping the jelly

Once harvested, the jelly is soaked in clean water until it expands evenly. It is then processed through specialized cutting machines to create cube-shaped pieces or long strips, depending on production needs. To ensure maximum safety, the jelly is cooked and sterilized in a pressure system before moving on to the final processing stage.

GC Food’s nata de coco is produced in a variety of shapes and sizes.

Step 3: Packaging

The coconut jelly topping is packed together with sugar syrup in sterile packaging conditions. By applying an automated system, GC Food minimizes human contact during processing, reducing the risk of contamination and ensuring consistent quality across every product.

7. How does factory production differ from homemade coconut jelly?

Below is a detailed comparison between making coconut jelly at home and producing it on an industrial scale:

Criteria	Homemade (Manual method)	Production at GC Food (Industrial scale)
Starter culture	Kombucha liquid	Acetobacter xylinum bacteria
Fermentation environment	Ceramic or glass jars covered with a thin cloth for natural fermentation	Large-scale fermentation tanks with strict temperature and pH control
Fermentation time	10 - 15 days, depending on weather and environmental conditions	7 - 10 days thanks to optimized conditions that ensure consistent thickness
Sterilization technology	Manual boiling and cooking with sugar syrup	Advanced Aseptic UHT systems and modern Pasteurization technology
