Guacamole is made primarily from fresh avocados and is widely popular in mexican, american, and european markets. So how to make guacamole step by step?
Guacamole processing steps
1. Avocado selection and pre-treatment
First, select avocados suitable for processing into guacamole, as underripe avocados will have a bitter taste and a pale color. Then, use a washing machine to remove dirt, pesticide residues, and impurities from the surface of the peel.
2. Peeling and pitting
Peeling and pitting of avocados are usually done manually to minimize damage to the flesh.
3. Pulping
After peeling and pitting, the avocado pulp is pulverized and homogenized in a blender to create a smooth avocado jam.
If a coarse texture is desired, coarse pulverization can be used.
4. Blending and mixing
Depending on the product type, onion powder, pepper, spices, oils, etc., can be added. After thorough mixing, the mixture must be vacuum degassed to remove air, prevent oxidation, discoloration, and microbial growth.
5. Sterilization treatment
Guacamole is a low-acid food, making it susceptible to microbial contamination; therefore, sterilization is crucial. Common sterilization methods include: Pasteurization (85–90℃, 15–20 minutes): Suitable for refrigerated products; high-temperature sterilization (htst): Suitable for products stored at room temperature.
6. Filling and packaging
Pasteurized guacamole can be packaged in various ways:
Glass jars (suitable for high-end products).
Vacuum packaging or aseptic bag packaging (extends shelf life).
Precautions for guacamole processing
1. Prevent oxidation and discoloration: Guacamole is rich in phenolic compounds, which are easily oxidized when exposed to air, causing the sauce to turn brown. It should be pulped as soon as possible after peeling, or antioxidants should be added.
2. Control temperature: Excessive temperature during processing will destroy the unsaturated fatty acids and vitamin e in avocados, affecting its nutritional value and flavor. The pulping and mixing stages should be controlled at 15–25℃.
Of course, in addition to the above precautions, there are also high requirements for the equipment used in processing guacamole. If you would like to learn more, please leave us a message.
