Blueberry seeds

Every blueberry has tiny seeds inside. In botany, a "true berry" is a fleshy or pulpy indehiscent fruit in which the entire ovary wall ripens into a relatively soft pericarp, and the seeds are embedded in the common flesh of the ovary.

The seeds are contained right within the fruit. They are tiny, soft, and completely edible. Seeds have an ornamented episperm, and a dark brown color when ripen. There is difference in size among mature seeds, varying from 0.49 to 1.02 mm long, and 0.44 to 0.61 mm wide.

These tiny seeds can range in number from between 10-20 seeds per fruit depending on if they are highbush or lowbush. Highbush blueberries are typically larger and will have around twenty seeds, whereas lowbush blueberries are smaller and will contain a number of seeds closer to ten.

Blueberry seeds can be extracted by three methods:
*Blender
*Food grinder
*Mash the berries

Blueberry seed oil

Blueberries are rich in antioxidative phenolic compounds, particularly anthocyanins. A blueberry seed oil is being recognized for their nutritional value as well as for being rich source of bioactive compounds including phenolics.

The fatty acids of blueberry seed oil consisted of 69% PUFAs, 23% MUFAs and about 8.5% saturated fatty acids and may serve as an excellent source of essential fatty acids, linolenic and α–linolenic acids, with a very good ration of n-6 to n-3 fatty acids 1:7:1.

Blueberries seed oil is a skin protecting oil with antioxidant properties and it suits most skin types, including those with acne or blemishes. It is also rich of vitamin E.

Blueberry: Fruit Characteristics

Blueberry: Fruit Characteristics
Fruit size is quite large for a wild Vaccinium, especially a diploid species. The general range in fruit diameters is from 5mm to 16mm, with occasional plants with fruit 19mm in diameter. Fruit size is positively correlated with number of developing seeds, and potentially viable seed number range from 5 to 29 per berry determined that plants with the largest fruit average occur in the Lexington Country, South Carolina and the coastal North Carolina/South Carolina border area.

The color of mature fruit is extremely variable, ranging from greenish-white, yellowish, light red, dark red, blue, purple-blue, purple black, reddish black, to dark purple. The surface of the fruit may be either glaucous or glabrous, and galaucousness on the fruit is generally correlated with galaucousness on vegetative parts. Fruits from plants in the South Carolina sandhill region were the most glaucous.

Fruits of V.stamineum typically have some bitterness in the skin, although the degree of bitterness and sweetness is quite variable. Fruits from the South Carolina sandhill region found to were the most palatable. Fruits typically drop to the ground as soon as they ripen and since the calyx tube is continues with the pedicel, the pedicel remains attached to the fruit.
