More about this report
Clinical studies show that red yeast rice products can dramatically lower LDL ("bad") cholesterol But our tests reveal that the amounts of cholesterol-lowering compounds in suggested daily servings can be as much as 500 times greater for one product than another, despite labels suggesting they provide the same amount of red yeast rice
Which are the best red yeast rice supplements? We identified at least three that have the amounts and types of compounds shown to work in clinical trials Unfortunately, we found many others that provide only small amounts of these compounds and seem unlikely to have any significant effect on cholesterol levels What's equally concerning, we discovered a potential toxin, citrinin in a well-known brand

Washing and Soaking
Koji Making (Seigiku)
After being moved to a larger tank, more rice, more koji and more water are added in three successive stages over four days, roughly doubling the size of the batch each time This is the main mash, and as it ferments over the next 18 to 32 days, its temperature and other factors are measured and adjusted to create precisely the flavor profile being sought
How Long Does Yeast Last?
How long does yeast last? Dry yeast is good for 2-4 months beyond its "best-by" date That being said, the shelf life of yeast depends on not only the best before date, but also how it is stored
Yeast is a leavening agent containing active enzymes that create CO2 (carbon dioxide) when moistened It is the starting ingredient in almost all bread recipes and the majority of baked goods in general that need to rise before baking
The best by date for yeast is two years after the date it was packaged Red Star, for example, stamps their products with the month & year that is two years out from the manufacture date For example, MAR 2014 08 09 - indicates that optimal results will be realized if the product is all used up by March of 2014 (the last 4 digits are for their own manufacturing purposes) 
Does yeast go bad? Yes, it does So, how long does yeast last? When properly stored (see below), yeast shelf life beyond its best by date is
Yeast Expiration Date
Remember that yeast, like a lot of other baking products, usually has a best before date and not a use by date or expiration date Because of this distinction, you may safely use yeast for your baking needs for a time after the best before date has lapsed
How to tell if Yeast is bad, rotten or spoiled?
Practicing proper hygiene and food safety techniques will help prevent foodborne illness
Yeast will eventually change from a light tannish grey to a darker brown color and begin to clump together when it is getting old Once you see these changes, the yeast has gone bad But before that, it will probably look fine but may or may not be alive and well When it is going bad, the organisms are becoming less active and dying So, older yeast will take longer to rise The best way to tell if yeast has gone bad is to perform the yeast freshness test that is detailed below
Yeast Freshness Test
Follow these steps to test if your room temperature yeast is fresh:
1) Dissolve 1 teaspoon of granulated sugar in 1/2 cup warm (110°-115°F) tap water inside of a one cup or larger measuring cup
NOTE: It is best to use a thermometer, but if you don't have one make sure the tap water is warm, not hot, when touched Water that is hotter than 120°F will kill the yeast and cooler water will not be able to activate the yeast
2) Stir in a yeast packet (or 2-1/4 tsp of dry yeast) until dissolved
3) Wait - in a minute, it should become activated and after 10 minutes should rise to the 1 cup mark
4) Use your test in your recipe right away (remembering to deduct 1/2 cup liquid from your recipe) - OR, if it did not rise then your yeast has gone bad and should be thrown away
There are, of course, certain health risks associated with spoiled foods so always remember to practice food safety and enjoy your foods before their shelf life has expired!
How to store Yeast to extend its shelf life?
Yeast is a living organism which becomes less active over time, much like yogurt cultures Like most foods, it perishes even quicker when exposed to air, moisture and/or heat
Unopened packages should be stored in the cupboard or other cool, dry place (refrigerator is fine too but not necessary until it is opened) Once the package or jar is opened, it must be refrigerated (or frozen) in an airtight container with as much air squeezed out as possible
For a long term option, dry yeast can be frozen for about 6 months after opening
Dry yeast should always be be brought to room temperature before using, so be sure to remove only the amount needed from the fridge or freezer about 30-40 minutes before using
Cake Yeast (also called Compressed) is even more perishable than dry, requiring constant refrigeration below 45°F to maintain its freshness and activity Always wrap remaining cake yeast tightly and store in an airtight container in the refrigerator Freezing cake yeast is not recommended Who has the time OR money.
Some benefits of proper food storage include eating healthier, cutting food costs and helping the environment by avoiding waste
