Sesame Seeds #2

Sesame seed varieties

 

This annual herb can grow as high as seven feet tall, though most plants

range two to four feet. The white to lavendar-pink flowers, similar in

appearance to foxglove, mature into pods containing the edible sesame seeds

which burst with a pop when the small seeds are mature. Since this process

scatters the seeds, the pods are often harvested by hand before they are

fully ripe. Sesame seed hulls are often removed since they contain 2 to 3

percent oxalic acid, which can interfere with the absorption of calcium and

give a bitter flavor. Prime season for sesame seeds is between September and

April when the new crops are harvested. A cologne is made from sesame

flowers. The oilcakes left after pressing sesame oil are rich in protein and

are used as cattle feed and as a subsistence food.

 

The seeds come in a variety of colors depending on the plant variety,

including shades of brown, red, black, yellow, and most commonly, a pale

grayish ivory. The darker seeds are said to be more flavorful, but beware of

seeds that have been dyed.

 

Sesame seed selection and storage

 

Sesame seeds have a nutty, slightly sweet flavor and aroma which is enhanced

by toasting. They are available packaged in the spice section and in bulk

quantity in Middle Eastern markets. Due to their high oil content, the seeds

will quickly become rancid. It's best to purchase them in small amounts and

use them quickly. Unrefrigerated seeds should be kept in an airtight

container in a cool, dry place for up to three months, refrigerated up to

six months or frozen up to one year. Sesame oil, on the other hand, is

remarkably stable and will keep for years without turning rancid, even in

hot climates. To bring out the nutlike flavor of sesame seeds, spread seeds

on a cookie sheet and toast in a 350-degree F. oven for 15-20 minutes,

stirring often.

 

Tahini

 

Tahini is a paste made of ground sesame seeds which is used in many Near and

Far East recipes. You can purchase it prepared in most markets, but it's

easy enough to make your own.

 

Health watch

 

Although sesame seeds contain no cholesterol, they are still 50 percent

unsaturated fat, so those watching their fat consumption should exercise

moderation. Luckily, a small amount goes a long way in flavoring foods. They

have a high magnesium content to help steady nerves and are used in

laxatives as an emolient. One-half cup of sesame seeds contains over three

times the calcium of a comparable measure of whole milk. Some studies show

that sesamin, a lignan found only in sesame seeds, has remarkable

antioxidant effect which can inhibit the absorption of cholesterol and the

production of cholesterol in the liver. The seeds are also rich in Vitamin

A, E and protein. An old folk remedy recommends thoroughly chewing and

swallowing one tablespoon of sesame seeds per day to regulate the menses.
