DisplayTitle 3-Part Sourdough Series
Page Content 
Sourdough is a method of breadmaking that requires special fermentation by lactic acid bacteria and wild yeast. It is believed to be the oldest method used to leaven dough and make bread. Both an art and a science, this process requires time. However, it produces bread with: - Extended Shelf-Life
- Superior Nutritional Profile
- Higher Digestibility
- Better Texture
- Unique Flavors and Aromas
Variations in the microflora, fermentation, conditions, types, and ratios of raw materials are responsible for differences in the functionality of the sour and subsequent flavor in the bread. Sourdough technology is commonly based on wheat or rye flours, or a mixture of both. Such breads have distinctive flavors largely arising from the ratio of acetic to lactic acid flavor notes. The manufactured bread is denser with a less aerated structure than many other wheat breads. The concept of modern sourdough technology is still based on the preparation of a 'starter' or 'mother' dough to exploit the principles of spontaneous fermentation.
Our Three Speakers Will Talk us Through:- The science of starter and sourdough bread quality as impacted by grain and flour quality
- Nutrition and health benefits of sourdough bread
- Commercial challenges of sourdough bread making

Bread baked with sourdough has been a traditional baking practice used in European countries for centuries. Now, this practice has gained popularity in many other parts of the world. Sourdough bread is of premium quality and is well-known for its distinct and very pleasing flavour, unique shape, and crispy crust. Italian Altamura bread, French baguette, and European dense rye bread are formulated with flour, water, salt, and sourdough which is used for natural dough fermentation. However, each type of bread is so unique due to the type of flour used, the nature of sourdough, and the way the dough is handled, shaped, and baked. Textural properties and flavour vary depending on bread type. Understanding the basic concepts of sourdough will provide a baker with the tools necessary to create unique bread of exceptional quality. This presentation will cover fundamentals on how to start a sourdough culture, develop it, and use it for bread baking. Baguette baked with liquid levain will be used as an example to explain the formulation and concepts of baking using a natural fermentation process. Flour quality requirements for sourdough bread will be explained as well.

Yulia Borsuk is an end products manager at the Canadian International Grains Institute (Cigi), where she is responsible for the activities related to the applicability of Canadian wheat in bread, Asian products, and pasta. This includes testing flour or semolina for functional quality in the final products, delivering practical baking demonstrations and workshops, conducting research and development projects, consulting and baking troubleshooting. Yulia also worked as a production supervisor in an industrialized bakery (Canada Bread Ltd.), where she gained experience in all aspects of commercial bread processing. Yulia is a co-author of a number of papers with a focus on the applicability of pulse flours in bread making. Yulia graduated from the University of Manitoba, Canada with an MSc in Food Science. She took a professional course on the French Breads and Viennoiseries at Ferrandi School, France. Yulia’s biggest passion in life is baking, and the smell of freshly baked rye bread made with sourdough at home is the highlight of her weekend. |
Nutrition and Health Benefits of Sourdough Bread

Sourdough fermentation is claimed to be a way of improving the nutritional profile of breads. This webcast is designed to investigate some of these claims. I am an experienced and trained sourdough baker. In my extensive travels through the sourdough world, some questions occur repeatedly. Often the first is the intersection of mineral availability, wholegrains, and phytate. Others include “digestibility”, although that is too nebulous a term and needs to considered with respect to starch, protein, and fiber individually, and as they interact. The topic of digestibility also crosses over into the realms of non-celiac wheat sensitivity, FODMAPs, and fructans. Other sourdough questions relate to glycæmic response, fiber, and the metabolites of the Lactobacilli themselves and their potential health impacts. My intent is to touch lightly on all these topics, and maybe others. As time and questions allow, we may be able to drill down a little more deeply into one or two topics.

Process consistency is the key to successful sour dough production. This starts with the starter preparation and continues through dough make-up and baking. Processing conditions need to be modified to deal with the soft and dense nature of sour doughs to deliver acceptable products.
