Why is zucchini bitter?

1. Zucchini tastes bitter because it contains a substance called "bitterness". This is related to the vegetable farmers' choice of vegetable seed varieties. Some zucchini seeds have a high content of bitterness, so the fruits grown naturally taste bitter.

2. Zucchini encounters some problems in planting and management, which causes the fruit to become bitter. For example, in hot and dry weather, the absorption function of the root system is weakened, and more bitter substances will accumulate; or it may be due to excessive nitrogen fertilizer application. If only nitrogen fertilizer is used, nitrogen nutrition will be excessive, which will also easily increase the concentration of bitter substances in zucchini.

Currently, it is impossible to tell the difference with the naked eye except by using professional instruments or tasting it yourself. However, the bitter zucchini itself does not contain any toxins. On the contrary, certain bitter substances contained in vegetables are beneficial to human health and can be used with confidence.

Differences between Winter Squash and Zucchini

Winter Squash

First of all, winter squash, also known as Indian pumpkin, jade squash, and northern squash, belongs to the Cucurbitaceae family and the genus Cucurbita, and is an annual vine herb. Artificial cultivation of winter squash is mainly for the purpose of obtaining tender squash and seeds. In terms of appearance, the stem of winter squash is nearly round. The leaves are soft and hairy, round or heart-shaped, with very shallow or no cracks, and no white spots. The corolla lobes are soft and droop outward, the sepals are narrow and long, and the buds are truncated at the opening tip. The fruit pedicel is short and cylindrical, and the base is not swollen. The fruit surface is smooth, the ripe fruit has no aroma, and the sugar content is low.

Zucchini is also known as bear (male) melon, wild rice melon, white melon, small melon, pumpkin, horned melon, and vine. It is an annual herbaceous vine (climbing). It is native to India and is planted in both southern and northern China. There are three major strains: dwarf, semi-climbing, and climbing. Most varieties of zucchini have a dominant main vine, with few and weak side vines. The stem of zucchini has ridges and grooves, short bristles and translucent rough hairs. The petiole is thick, covered with short bristles, and is 6-9 cm long. It likes moisture and is not drought-resistant. Especially during the melon-bearing period, the soil should be kept moist to obtain high yields.

Therefore, the most direct way to distinguish the two is to look at the pedicel, which is the stem. The pedicel of winter squash is cylindrical, without ridges on the surface, and the part in contact with the fruit is not significantly enlarged. The pedicel of zucchini has obvious ridges on the surface, but the part in contact with the fruit is not significantly enlarged, at most it is slightly thickened.
