The Food and agriculture Portal

Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells in an effort to produce energy, maintain life, and/or stimulate growth. Historically, people secured food through two methods: hunting and gathering, and agriculture.

Agriculture is the cultivation of animals, plants, fungi and other life forms for food, fiber, and other products used to sustain life. Agriculture was the key implement in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that nurtured the development of civilization. In the developed world, industrial agriculture based on large-scale monoculture has become the dominant system of modern farming, although there is growing support for sustainable agriculture (e.g. permaculture or organic agriculture).

Sustainable agriculture is the practice of farming using principles of ecology, the study of relationships between organisms and their environment. It has been defined as "an integrated system of plant and animal production practices having a site-specific application that will last over the long term: satisfy human food and fiber needs; make the most efficient use of non-renewable resources and on-farm resources and integrate, where appropriate, natural biological cycles and controls; sustain the economic viability of farm operations; and enhance the quality of life for farmers and society as a whole.”

Yeast Cakes from Hops
Yeasts for Baking. Generally when one mentions yeast, aromatic loaves of fresh homemade light bread come to mind. And so they should. Aside from acting as a leavening agent in bakery products, yeast is also the ingredient responsible for the tantalizing aroma that arises during baking.

Though probably today the most commonly known and used are store-bought packages of dried yeast, there are several other different kinds. The recipes that follow show two examples of different ways to make yeast--dry yeast cakes made from hops and an everlasting yeast "starter"--and also how the yeasts are used in making bread.

The dry yeast cakes are made in part by boiling the blossoms of the hop vine. These flowers contain a fragrant yellowish oil called lupulin. The use of this oil as a preservative in beer and as a narcotic drug originated in Germany before Charlemagne. Since then its use has become widespread and the vine cultivated in other nations, including America.

The hop vine is related to the hemp and mulberry plants in the nettle family. The plant itself is twenty-five to thirty feet in length with rough lobed leaves and flowers that grow on catkin clusters. It is quite possible that many people in the Ozarks have never seen a hop vine, because although some Ozarkians have had limited success cultivating it, it grows best in sandy coastal regions.
