Suitability of celery for freezing

Apium graveolens L.

Due to its high water content and delicate cellular structure, celery loses its crunch when frozen, becoming suitable only for heat treatment. Success in this process depends on variety selection and mandatory blanching, which inactivates tissue degradation enzymes.

In the reference 12 varieties crop Celery, where this is mentioned in the description.

Celery contains approximately 95.4% water and possesses sensitive parenchyma cells, causing cellulose hydrolysis during freezing. This leads to the loss of natural crunch and tissue softening, rendering the product unsuitable for raw consumption after thawing. Its primary purpose after storage is use in soups, stews, sauces, and broths.

The degree of tissue firmness retention depends on varietal characteristics: varieties with high fiber content and lower moisture, such as Utah Tall, perform better than Pascal-type varieties. A key technological step is blanching, which inactivates enzymes that trigger chlorophyll degradation and cellular structure breakdown, allowing the product's shelf life to be extended from 1–2 months to 1.5 years.
