Use for Grape Waste


Waste from food products is nothing new. Humans throw out immense amounts of food waste daily. Organic material can be used in home compost bins, but few are motivated to do so. The large amount of people living in apartments with no green space also leaves little option for many people to recycle their waste outdoors. Wine is one of the largest productions worldwide that involves a single type of produce. While the juice is used to make your evening glass of wine, the skin, seeds, and stalks make their way to landfills. Considering the extremely large numbers of this particular product, scientists are working hard to find other uses for this grape waste. 

Environmental Risks 

Any item in excessive amounts can be dangerous for the environment. Grapes, in particular, cause a special concern. Non-organic grapes are known to have the highest level of pesticide of many other forms of produce. Grape waste carries these toxins with them when they are discarded. The highly acidic nature of grapes is also thought to have negative effects on the surrounding soil. Landfills are not closed up until they are full, often leaving grape waste exposed for a long time. The resulting attraction of flies and other insects is also thought to be a health hazard. If any portion of this waste can be recycled, the health of the environment can benefit. This waste is called pomace and its productions exceeds 14 million tons every year.

Making it Safe and Ongoing Research

In order to use pomace in the many possible applications, some changes must be made to it. The pesticides are a problem when it comes to making anything that people may ingest. Scientists are working to find a way to extract it.  Other than this one setback, however, the outlook for using grape waste in many products is good. Grapes are an excellent source of antioxidants. Antioxidants fight free radicals in the body, slowing the signs of aging, and may even reduce the risk of some cancers. One goal is to separate the nutrients for use in new products.

There is ongoing research geared towards finding out what the best uses for the grape waste would be. One idea is centered on its possible that the polyphenols found in grape waste is helpful in eliminating E.coli, And Salmonella. Detailed research is aimed at the possibility of improving the lives of babies. Pregnant pigs are given the grape pomace in an effort to see how it affects the well-being of the gut of the piglets. With the abundance of allergies in today’s society, babies are having issues with absorption of many foods. Infections of the gut also bring many risks. Grape waste may hold some of the answers.

Other Uses

It turns out that grape pomace is pretty useful in many areas. It may be put back into your food. For foods that aim to have only natural ingredients listed, this may be the answer. Antioxidants are often added to food products, however, they are supplemental and cannot be referred to as organic or natural. This would allow manufacturers to come closer to achieving the sought-after “clean label.” This could also be a natural way to keep food from going bad as soon. It has been found to slow down lipid oxidation, which makes products last longer. This is especially helpful in foods with a high fat content. Medications and makeup are on the list for the addition of grape waste, as well.

With the decline of today’s environment, and the incredible amount of food waste made every day, it is extremely important that new uses are found for leftovers of popular food items to avoid adding to waste collection sites. Grapes are unique, as they are popular all over the globe for use in wine. This makes the waste much larger in amount than some other products. With these research efforts underway, the applied usage could be happening sooner than we think. While some setbacks could occur as scientists figure out how to remove fertilizer and pesticides, the outlook is promising. You are soon to be fixing your face with makeup made from grape waste and enjoying longer lasting foods because of its antioxidant properties.
