Yes, malt extract broth can be heat sterilized, typically by autoclaving at 121°C for 15-20 minutes. This process effectively eliminates microbial contaminants while preserving the nutrients in the broth. It's important to ensure that the broth is in a suitable container to withstand the heat and pressure of autoclaving. After sterilization, the broth should be handled aseptically to maintain its sterility.
Yes, yeast cells can grow on malt extract agar, as this medium provides the necessary nutrients, including sugars, vitamins, and minerals that yeast require for growth. Malt extract agar is specifically formulated to support the growth of fungi, including yeasts, making it suitable for isolating and cultivating these organisms in laboratory settings. The presence of malt extract serves as a carbon source, promoting yeast proliferation.

Malt extract is a mixture because it is composed of various compounds extracted from malted barley, including sugars, proteins, vitamins, and minerals. It is not a single pure substance like a compound.
Vegemite is made from yeast extract. It mainly consists of protein amino acids (mostly glutamic acid, which causes the umami flavour) carbohydrates and salt. Hence the chemical elements are: carbon, hydrogen, oxygen, nitrogen, sulphur, sodium and chlorine.
Ovaltine primarily consists of malt extract, sugar, cocoa powder, and whey protein. It also includes various vitamins and minerals, such as B vitamins and calcium, depending on the specific formulation. Additional ingredients may vary by product version, such as chocolate or rich malt flavors. Some varieties may also contain emulsifiers and flavorings.
Yes, malt extract and malt powder are both derived from malted barley, but they are not interchangeable in all recipes. Malt extract is a concentrated syrup made from malted barley, while malt powder is a dried form of malt extract. Malt extract is typically used in brewing beer or baking, while malt powder is often used as a flavoring or sweetener in beverages or desserts. The different forms may have varying levels of sweetness, moisture content, and flavor intensity, so it's important to consider these factors when substituting one for the other in a recipe.

Barley malt extract itself does not contain alcohol. It is a concentrated syrup made from malted barley, primarily used as a sweetener and flavoring agent in food products. However, during the fermentation process, which can occur if yeast is introduced, alcohol can be produced from the sugars in the malt extract. But in its typical form, barley malt extract is non-alcoholic.
Malt extract agar typically consists of malt extract, agar as a solidifying agent, and may also contain additional nutrients like peptone or yeast extract. The exact composition can vary depending on the manufacturer or specific recipe used.

The presence of malt extract serves as a carbon source, promoting yeast proliferation.
One teaspoon of malt extract typically weighs about 7 to 8 grams. However, the exact weight can vary slightly depending on the density of the specific malt extract being used. For precise measurements, it's best to refer to the packaging or use a kitchen scale.
To convert DME (dry malt extract) to LME (liquid malt extract), you can dissolve the DME in water at a ratio of 1:1. This means for every ounce of DME, you would add one ounce of water. Stir the mixture until the DME is fully dissolved to create a liquid malt extract.
The one I remember was called Viral.

To convert an all-grain recipe to an extract recipe, you can substitute the base malt with an equivalent amount of liquid or dry malt extract. You may also need to adjust the hop additions to account for the higher utilization of hops in extract brewing. Additionally, consider using specialty grains to add complexity and flavor to the extract recipe.
