Soybeans are a versatile crop that can be used for a variety of purposes, including making soybean oil, soy milk, tofu, and other soy-based products. Soybeans are also an excellent source of protein, making them a popular ingredient in vegetarian and vegan diets. However, before you can use soybeans in your favorite recipes, you need to process them.

Processing soybeans involves soaking, dehulling, conditioning, crushing and extracting oil. To begin, soybeans are soaked in water for several hours before the hulls are removed. Once the hulls are removed, the beans are conditioned by heating and adjusting moisture content. The beans are then crushed, which separates oil from the meal, and the oil is extracted from the meal. After the oil has been extracted, the meal is then dried and packaged for sale.

How To Process Soyabeans Step By Step Guide

Processing soyabeans gives you the liberty to prepare different variety of meal and allow you enjoy soyabeans meal in different form. We have carefully outline and explained the steps involved on how to process soyabeans from beginning to ending.

Step 1. Acquire your Soyabeans

Acquiring soybeans is the first step in processing them. You can either grow your own soybeans or purchase them from a local farmer or grocery store. When purchasing soybeans, make sure to select high-quality beans and inspect them for any damage or debris. Growing soybeans requires adequate soil, water, and sunlight. Regardless of how you acquire your soybeans, ensure they are clean and sorted before processing.

Step 2. Cleaning and Sorting Soybeans

The first step in processing soybeans is to clean and sort them. Soybeans may contain dirt, rocks, and other debris that needs to be removed before processing. Sorting soybeans involves removing any damaged or discolored beans.

Here’s how to clean and sort soybeans:

Pour the soybeans into a large bowl or container and pick out any debris, such as dirt or rocks.
Rinse the soybeans in a colander under cold running water.

Spread the soybeans out on a clean surface and sort through them to remove any damaged or discolored beans.

Step 3. Crushing and Dehulling Soybeans

After cleaning and sorting, the next step in processing soybeans is to crush and dehull them. Crushing the soybeans separates the oil from the protein-rich meal, while dehulling removes the outer shell of the soybean.

Here’s how to crush and dehull soybeans:

Place the soybeans in a soybean crusher and crush them to a fine powder. If you don’t have a crusher, you can use a blender or food processor to grind the soybeans.

Transfer the crushed soybeans to a dehulling machine. The dehulling machine will remove the outer shell of the soybeans, leaving behind the soybean meal.
Use a sieve to separate the soybean meal from any remaining hulls. The soybean meal can be used for making tofu, soy milk, and other soy-based products.

Step 4. Solvent Extraction

Solvent extraction is the process of extracting soybean oil from the soybean meal. The soybean meal is mixed with a solvent, such as hexane, which dissolves the oil. The oil is then separated from the solvent using a distillation process.

Here’s how to extract soybean oil using solvent extraction:

Mix the soybean meal with a solvent, such as hexane, in a mixing tank. The solvent will dissolve the oil in the soybean meal.

After mixing, the mixture is transferred to a distillation tank, where the solvent is removed from the oil using a distillation process.
The soybean oil is then collected in a separate container.

Step 4. Refining Soybean Oil

After extracting the soybean oil, the next step is to refine it. Refining involves removing any impurities from the oil, such as free fatty acids, phospholipids, and other substances that can affect the quality and stability of the oil.

Here’s how to refine soybean oil:

Heat the soybean oil in a deodorization tank to remove any unpleasant odors or flavors.

Mix the soybean oil with an acid solution to remove any free fatty acids and other impurities.
Add a degumming agent to the oil to remove any phospholipids.
Heat the oil again to remove any remaining impurities.

Filter the oil to remove any solids or remaining impurities.

Step 6. Producing Soy Protein Isolate

The protein powder made from soybeans, known as soy protein isolate, is a superior-quality protein source. It is often used as a food ingredient in products like protein bars, meal replacement shakes, and other supplements.

Here’s how to produce soy protein isolate:

Mix the soybean meal with water in a mixing tank to create a slurry.
Adjust the pH of the slurry to around 9.5 using an alkaline solution, such as sodium hydroxide or potassium hydroxide. This helps to separate the protein from the other components of the soybean meal.

Heat the slurry to around 85-90°C and maintain the temperature for around 30 minutes. This denatures the proteins in the soybean meal and helps to separate them from the other components.
Centrifuge the slurry to separate the protein from the other components. The protein will form a solid mass, while the other components will remain in the liquid portion of the slurry.
Wash the protein mass with water to remove any remaining impurities.

Neutralize the protein mass by adding an acid solution to adjust the pH to around 7.
Dry the protein mass to remove any remaining moisture. The resulting powder is soy protein isolate, which can be used as a food ingredient.

Benefits of Processing Soybeans

Processing soybeans offers a number of benefits. For one, soybeans are a rich source of protein, which can be isolated and used in a variety of food products.
Soybeans also contain a range of nutrients, including vitamins, minerals, and antioxidants, that can promote health and prevent disease.
Processing soybeans can increase their shelf life, making them more convenient to store and use.

Soybeans can be processed into a wide range of products, from tofu and soy milk to soybean oil and soy protein isolate.

How to Preserve Processed Soybeans

Once soybeans have been processed, it’s important to store them properly to ensure their quality and freshness.

The best way to store processed soybeans is in an airtight container in a cool, dry place. Avoid exposure to moisture, heat, and sunlight, which can cause the beans to spoil or go rancid.

Processed soybeans can also be stored in the freezer for longer-term storage. If you’re unsure about the shelf life of your processed soybeans, check the packaging or consult with the manufacturer.

For one, some people may be allergic to soybeans or have an intolerance to soy products.

Soybeans are often genetically modified, which can be a concern for some consumers.
Processing soybeans can involve the use of chemicals and other additives, which can have negative health effects if consumed in large quantities.

Factors that Affect Soybean Processing

There are several factors that can affect the processing of soybeans. One of the most important is the quality of the beans themselves.

High-quality soybeans will yield better results than beans that are damaged or contaminated. The processing method used can also affect the quality of the final product.

Different methods may be used depending on the desired end product. For example, soy milk is typically made by soaking and grinding soybeans, while soy protein isolate is made through a more complex process that involves the use of chemicals and centrifugation.

Other factors that can affect soybean processing include temperature, pH, and the presence of enzymes and other substances that can affect the protein content and quality of the beans.
