A Primer On Preservatives
Ensure food safety and quality by using the correct additives
Baked goods, like all other foods, must be safe when consumed. At the same time, they need to be of good quality, delivering excellent taste and texture. Over the many years of producing such foods, the baking industry has relied on a multitude of ingredients to ensure safety and quality.
When discussing the safety of baked goods, we are primarily concerned with microbiological contamination as well as the danger of chemical contamination with natural toxins such as mycotoxins, which are usually controlled by close monitoring of these toxins in the flour supply. Bakers rely on suppliers to provide certificates of analysis confirming levels of such toxins.
Microbiological contamination, however, with the exception of spore-forming bacteria, mostly occurs after the baking process. For this reason, preservatives are used in baking formulations to ensure microbes are controlled and do not grow during the shelf life of the product. These ingredients provide safety by controlling possible pathogens, and they ensure quality by preventing the growth of spoilage organisms. They can be synthetic chemicals or natural extracts.
Some of the popular natural antimicrobials include vinegar and other natural acids, raisin juice concentrate, as well as juice concentrates from other fruits. Some spices such as cinnamon may also act as antimicrobials.
Fruit And Vegetable Preservatives
Fresh produce is ideal for makingnatural preservatives. It comes as no surprise that, in recent years, researchers have developed innovative plant-based preservatives.
Scientists at Singapores Nanyang Technological University have harnessed the anti-microbial and antioxidant properties of flavonoids a naturally occurring substance in almost all fruits and vegetables. These chemicals defend plants against pests, pathogens, herbivores, and even environmental stress. They are also responsible for their vivid colors .
This organic preservative is entirely natural and more effective than artificial ones. Moreover, it allows food to forego any further processing to stay fresh .
Fruit puree can be used for more than just acake fillingor an ingredient in differenttypes of pastry. Fruit can help control some factors limiting foods shelf life, like oxidation, microbial spoilage, staling, color or flavor degradations, moisture change, and loss of nutrients .
Specifically, using fruit puree in food production can help control water activity in edible goods by binding free water and lowering moisture. It also contributes to managing their pH levels. Furthermore, fruit ingredients enhance products by adding color, acid, sweetness, and overall flavor .
What Is The Role Of Preservatives In The Baking Industry
We use food preservatives to make sure the food we consume on an everyday basis is safe and of good quality. Moreover, additives also affect the way our food tastes.
The role of preservatives in baking is multiple. Yet its prime goal is to keep the baking products fresh for more than just a couple of days.

Work Cinnamon Into The Recipe
Like honey, cinnamon is one of those naturally occurring miracle workers that can simultaneously improve flavor and lengthen shelf life. This delicious, warming spice offers natural microbial properties, preventing it from developing mold or becoming hard and stale. This is a great option for when youre baking cookies, muffins and sweetbreads that could benefit from a bit of cozy cinnamon flavor.
Extending Shelf Life: Its Only Natural
Key reasons why food producers need to seriously consider biopreservatives as a means to extend shelf life naturally and reduce food waste.
Consumers are demanding more from their food than ever before. And Im one of them! For example, I would be delighted if the baked goods, dairy products, and beverages I buy today could stay fresh and appealing for longer. However, its important to me that such improvements do not come at any cost It shouldnt have a negative impact on flavor and I dont want to see artificial preservatives in the ingredients list.
At DSM we have identified four reasons why it makes sense for food manufacturers to consider extending shelf life naturally rather than artificially, and seriously look into biopreservatives or anti-oxidants.
1. Extending shelf life helps reduce food waste.2. Consumers prefer natural preservatives.3. Most consumers check expiry dates and labels.4. Shelf life problems can damage reputation.
In this blog post I would like to take you through the first two reasons, and cover the other two in a later article.

How Is It Different Than Sourdough
Isnt cultured wheat just the same thing as a sourdough? Not quite. Sourdough is a mix of water and flour thats been fermented with lactic acid bacteria , along with acetic acid. This is what gives sourdough that distinct flavor.
However, although the process is similar, cultured wheat is used as a preservative, not a flavor enhancement.
Read all about cultured wheat and how to use it here.
Reasons For Adding Preservatives To Baking Goods
Next to the main goal of using food preservatives that we have already mentioned, there are more reasons for their unavoidable presence in our nutrition.
Artificial food preservatives are crucial for keeping our food safe. The biggest worry with food spoilage is chemical and microbiological contamination. Eating contaminated food products leads to critical illnesses. Additives control microbes responsible for the contamination of baking products.
The soft and yeasty crumb in bread is an ideal breeding ground for fungus and bacteria. Because of this, besides flour, sugar, and water, we use bread preservatives in almost every baking formulation.
Another role of preservatives in our food is to keep its moisture and texture.
Antioxidants prevent discoloration and stabilize fats and oils.

Natamycin As A Yogurt Preservative
Yogurts because of their low pH can be prone to spoilage by yeasts and molds. A preservative is required that has no negative effects on the viability and fermentation performance of the bacterial starter cultures used in yogurt production, but it shows amtimicrobial activity against yeasts and molds. The selective antimicrobial action of natamycin meets this criteria and natamycin is an effective preservative in both set and drinking yogurts. The natamycin can be added to the milk before or after pasteurization at the same time as the inoculation of the starter cultures. The effect of natamycin at concentrations ranging from 0 to 20 g ml1 against an inoculated yeast is shown in Figure 2.

Use An Oxygen Absorber Packet To Extend Cookie Shelf Life
If youve ever opened up a packet of beef jerky or dried fruit, chances are that youve seen oxygen absorber packets placed in the bottom of the bag. This is done for shelf life extension purposes and works by getting rid of the oxygen that encourages rotting.
Chefs concerned about mold growth might want togive these a try as well. These packets also prevent mold formation byabsorbing water molecules in the local environment, which makes the containerholding the cookies fairly inhospitable to mold spores.
The length of time these packets will extendcookie shelf life varies, but its generally seen as a good add-on for regularcontainer storage. The only thing you should watch out for is using this methodwith cookies that need to retain moisture. Since the packets dry outsurroundings, this could potentially make your baked goods a little dry.

What Are The Different Types Of Bread Preservatives
There are many different types of bread preservatives, both chemical and natural, but all usually work towards one or more of three main goals: strengthening the overall integrity of the loaf, slowing the growth of mold and decomposition, and fighting off bacteria. Bakers typically rely on a range of preservatives to help keep their bread fresh and shelf-stable for more than just a few days. Home cooks often dont need to worry about this, particularly not if they plan on eating their creations right away, but preservation is often a real cause for concern for commercial manufacturers. Chemical additions to bread have been going on for a long time, but the practice is nevertheless debated, particularly in health circles. Many research organizations have begun questioning the safety of many additives, and have lobbied for more all natural selections. Food regulatory agencies in many places have also placed certain limits on what many commercial breads can contain, as well as how the contents must be disclosed to consumers.

Extending Shelf Life Helps Reduce Food Waste
Roughly one third of the food produced in the world for human consumption every year gets lost or wasted. That equates to a staggering 1.3 billion tonnes of food! In industrialized countries more than 40% of losses happen at retail and consumer levels.1
The good news is that several studies indicate that this massive food waste mountain could be reduced by extending shelf life. According to research by WRAP, an increase of shelf life of just one day could help prevent up to 0.2 million tonnes of household food waste!2 Biopreservatives can play a key role in reducing food waste.

So Long Artificial Preservatives Natural Mold Protection For Baked Goods
The great reverence and aspiration behind our grandparents traditional baking recipes is the aura of wholesome natural ingredients. Realistically, I dont believe my parents or grandparents had any qualms about using Crisco or any number of synthetic ingredients in their baking if they were readily available. Remember this is back when trans fats were still generally recognized as safe by the US Food & Drug Administration?
Continuing the story from clean label bakery texture improvers must include the second great culprit of baking: MOLD! Clean label options exist for bakery products to replace highly functional ingredients like propionates and sorbates. Grocery store baked goods utilize these secret ingredients such as Calcium Propionate that are readily apparent when you read the ingredient declaration, but their actual function is somewhat mysterious to most consumers. At a grocery store you can buy all the ingredients to bake bread, or you can buy extended shelf life bread, but you cant really buy the ingredients to make extended shelf life baked goods at the grocery store.
Without buying fresh baked goods a few times a week, the only way to keep mold back is to use preservativesincluding natural preservatives.

The Gluten Network In Bakery And Pasta Products
Most baked goods and pasta products are made from wheat flour . The proteins from common wheat can be divided into two groups: albumins and globulins, which are called water-soluble proteins and account for 15% of total proteins and gliadins and glutenins , which are water-insoluble , network-forming, storage proteins and account for 85% of the total protein content.
During bread making, under appropriate conditions of mixing and dough development, gliadin and glutenin form a viscoelastic network called the gluten network. This network is the main determinant of dough properties prepared with good quality WF, as it has gas-retaining properties, and results in desirable loaf volume and crumb structure, which are important characteristics for bread texture .
Pasta is produced by hydration of flour followed by cold extrusion or lamination in cylinders, which leads to the development of the gluten network. This is essential for dough elasticity and the retention of starch granules and results in a firm cohesive structure with minimum cooking losses .
