Зелена груша Anjou

The d'Anjou pear is considered a medium to large fruit, typically around 270-285 grams, 85 mm in height and 80 mm in diameter. It has a wide, globular base, a short stem and a thin skin with many notable lenticels. The Red Anjou pear originated as a naturally occurring bud sport found on Green Anjou trees, and it is very similar to the original Anjou other than color.

Cultivation and Ripening

Pyrus communis, the common pear, is a species native to central and eastern Europe and western Asia. It is the species from which most orchard pear cultivars grown in Europe, North America and Australia have been developed. Some varieties, such as Beurre d'Anjou, ripen only with exposure to cold.

It is recommended to test the top near the stem with a slight press of the thumb until it gives slightly, because the pear does not show ripeness by color. The pear ripens from the inside out, and the top is closest to the inside. It typically takes 3 to 5 days after purchase for the pear to ripen.

Uses

The d'Anjou pear can be used for baking or sliced in salads, and it is also good for poaching, roasting, grilling, or eating fresh. As of 2004 it represented 34% of reported U.S. pear production, with Oregon the leading state.

Aroma Chemistry

The volatile profiles of eight pear varieties including Anjou are characterized by esters, alcohols, hydrocarbons, aldehydes and ketones. Across those varieties, esters comprise 60 to 98% of total volatiles. Hexyl acetate is the major ester in all eight varieties except Bosc, Vicar of Winkfield and Seckel. Decadienoate esters were detected in all eight varieties, but varied in amount and isomerization characteristics.

The concentrations of the pear esters ethyl (E,Z)-2,4-decadienoate and ethyl (E,E)-2,4-decadienoate were determined in six pear varieties, Anjou among them. Bartlett, the variety mostly used for brandy production, has high amounts of both esters. Pear ester is a colorless liquid. It is found in apples, Bartlett pears, Concord grapes, beer, pear brandy and quince.
