What is the grittiness in a pear?
It turns out that the grit in pears is caused by stone cells (also known as sclereids) — the same material that makes walnut shells and cherry pits hard. All pears produce stone cells, but there are a few ways to get around them.
What are the little hard bits in pears?
They are called stone cells. Botanically speaking, stone cells are one variety of a group found in most plants. These cells have hard walls, and they are found in the hard parts of plants, like stems and nutshells. The fruit of pears always has stone cells scattered through it.
Can you eat gritty pears?
While most people like the fragrance and taste of Pears, many won’t eat them. Most will give just about the same reason: they dislike the mealy, gritty texture. This exasperates Pear lovers, who will point out that they’re Pears, after all, not bananas.
Why do pears have sclereids?
The texture of the pear, which is a type of pome, is characteristically gritty, a quality that is related to the presence of special cells called sclereids or stone cells. Sclereids are variously shaped sclerenchyma cells with thick, lignified walls that function in providing structural support and strength to tissues.
Is it OK to eat pear skin?
Pears are an excellent source of soluble and insoluble fiber, which are essential for digestive health. As pear skin contains a substantial amount of fiber, it’s best to eat this fruit unpeeled ( 2 ).
What is gritty texture?
Gritty things have a rough texture that makes them feel like they’re coated with sand. Grit is a tiny particle of sand or stone, and gritty means “covered in grit.” A second meaning of gritty is “showing bravery and spirit.” When you stick with something no matter how scary or difficult it is, that’s gritty.
Are pears healthy?
Pears are a powerhouse fruit, packing fiber, vitamins, and beneficial plant compounds. These nutrients are thought to fight inflammation, promote gut and heart health, protect against certain diseases, and even aid weight loss. Just be sure to eat the peel, as it harbors many of this fruit’s nutrients.
Why are my pears Woody?
Pears that are left to ripen on the tree get mealy and woody. They are picked when mature, but not ripe, and then left to ripen off the tree. They ripen from the inside first. To determine if a pear is ready for eating, gently squeeze the fruit at the stem end.
Are sclereids dead?
Mature sclerenchyma cells are usually dead cells that have heavily thickened secondary walls containing lignin. The major function of sclerenchyma is support. Unlike collenchyma, mature cells of this tissue are generally dead and have thick walls containing lignin.
What are sclereids made of?
Sclereids are a reduced form of sclerenchyma cells with highly thickened, lignified cellular walls that form small bundles of durable layers of tissue in most plants. The presence of numerous sclereids form the cores of apples and produce the gritty texture of guavas.
What is pear grit made of?
Pear grit. Pear flesh is infused with very fine grit, made of clusters of stone cells. Stone cells, a subtype of sclereid cells, make up some other very hard tissues like peach pits and nut shells. Stone cells are born with their own death as an end goal. They begin as all other plant cells do, with thin primary walls.
What does a single gritty bit of pear mean?
A single gritty bit of pear is usually a cluster of several stone cells, but even individual cells are large enough to discern without magnification. It is possible to stain them so that they show up hot pink under a light microscope, and we sometimes do this in the botany classes I teach.

What is an pear fruit?
Pear fruit develops from an ovary that is below – or inferior to – the rest of the flower, which is why their stem is on one end of the fruit and the floral remnants are on the other.
