WHEAT BERRY PHYSIOLOGY
Included inside of an unaltered whole wheat berry are the elements needed to encourage growth. The protective wrapper of the wheat berry (generally known as the bran) contains fiber and nutrients. The starchy interior of the seed is known as the endosperm. Until such time as the root system of a new seedling is grown, the endosperm supplies the germinating seed with essential nourishment. The germ is a small embryo of the next plant. Flour from commercially machined wheat has the germ and bran stripped out, and also the associated benefits. Retailed ‘enriched’ flours are required by law to have 3 or 4 synthetic vitamins added to them. Conversely, eleven minerals and sixteen vitamins reside in a wheat berry https://kefirgrains.ie/product/organic-certified-san-fransico-sourdough-culture-80g/.
PERFECTLY DESIGNED SEEDS
The intact wheat berry arrives with strains of bacteria that live well on grains. One gram of flour includes about 13,000 yeast cells. Your starter will be populated by yeast that are specially matched to live off of grain. Yeast microorganisms in the air need not be harnessed by opening your starter to the air. An open starter will simply draw insects and pests which are undesirable.
Lactobacillus and yeast bacteria thrive within the flour and water mixture that is a sourdough starter. At room temperature the microorganisms are balanced, having yeast reproducing at a more measured rate as compared to lactobacillus. In cool storage, lactobacillus development is slowed. Generally, you’ll wish to keep your starter in an area in which the temperature stays in between 65 to 85 °F. For cooler homes, you may need to find a heated place around a light bulb, atop a family fridge or near a heating unit. In residences which are not cooled, a starter can be kept from overheating by resting in a bowl of water.
A SYMBIOTIC RELATIONSHIP
An isolated strain of yeast is all that’s included within baker’s yeast while a balanced sourdough starter includes both yeast AND lactobacilli. Both of these organisms were created to function mutually within a symbiotic relationship. Lactobacilli are anaerobic microorganisms which live off of carbon dioxide. The yeast survives off of the endosperm and creates carbon dioxide as a byproduct of the activity. The lactobacilli which have been enriched by the carbon dioxide then stop harmful bacteria from populating the starter.
