The suitability of zucchini for freezing is determined by its high moisture content and enzyme activity, which requires mandatory inactivation to preserve quality. Fruits at the stage of technical maturity with firm flesh and undeveloped seeds possess the best characteristics.

crop Field pumpkin,
where this is mentioned in the description.
Zucchini is characterized by a high water content, reaching 95%, which during conventional freezing leads to the formation of large ice crystals that destroy cellular structures. As a result, after thawing, the flesh loses its firmness and becomes watery. High enzymatic activity in tissues without pre-treatment causes fruit browning, the development of bitterness, and a decline in flavor quality during storage.
The technological suitability of fruits for freezing depends on varietal characteristics: preference is given to varieties with firm flesh and a small seed cavity volume. Overgrown fruits with a coarse texture are considered unsuitable. To minimize negative changes, a critical stage is blanching for 2–3 minutes to inactivate enzymes or pre-pressing moisture from the grated mass.
