Cal Poly Develops Formula for Preventing Browning and Microbial Growth on Fresh-cut Produce

My name is Janel Takeda, and I work in the Office of Research and Economic Development at California Polytechnic State University, San Luis Obispo. 

I am e-mailing The International Mango Organization (IMO) to bring to your attention a new antibrowning composition developed at Cal Poly to be used on freshly cut fruits and vegetables. 

We would encourage you to run a press release on the IMO website. We have attached a copy of the press release for your convenience. 

Dr. J. Wyatt Brown, a professor in the Horticulture and Crop Science Department at Cal Poly, has developed an antibrowning composition to be used on freshly cut fruits and vegetables. 

His composition not only is highly effective in improving the aesthetic quality of fresh produce but also prevents the growth of bacteria and mold. 

This is both exciting and valuable as it introduces readers to a new method that will benefit both the consumer and horticulture industry. 

Dr. Brown can be available to answer any technical questions you might have at 805-756-6137. 

Thank you for your time and consideration.

 SAN LUIS OBISPO, Calif. — Cal Poly has developed an anti-browning formula to prevent enzymatic browning that affects the aesthetic quality of fresh-cut fruits and vegetables.

 The product also reduces the growth of aerobic bacteria, yeasts and molds significantly. 

The multifunctional formula is an alternative to current anti-browning methods that focus solely on the appearance of food products. 

In addition, the formula is effective in ambient conditions – special packaging is not required. 

The anti-browning formula extends the shelf-life of produce via a combination of calcium ascorbate, calcium propionate and calcium chloride. 

The formula is the result of more than 400 tests and 4 years of research conducted by Dr. Wyatt Brown and his team in Cal Poly’s Horticulture & Crop Science Department in the College of College of Agriculture, Food & Environmental Sciences. 

The formula, when applied to pre-cut Granny Smith and Fuji apples, prevented browning and the growth of aerobic bacteria, yeasts and molds for a minimum period of 21 days. 

It has also been shown to be highly effective at preventing the browning of other sliced fruits and vegetables.

 In June 2015, Cal Poly was granted a 
United States patent for
anti-browning/antimicrobial composition (U.S. Patent Number 9,044,045). 

Cal Poly is actively seeking licensees to commercialize the formula.

While "Flavor" is very subjective, and each country that grows mangoes is very nationalistic, these are the mango varieties that are the most sought after around the world because of sweetnesss (Brix) and demand.

Carabao claims to be the sweetest mango in the world and was able to register this in the Guiness book of world records.
Perhaps it is time for a GLOBAL taste test ???

Mangoes date back 65 million years according to research ...

Experts at the Birbal Sahni Institute of Palaeobotany (BSIP) here have traced the origin of mango to the hills of Meghalaya, India from a 65 million year-old fossil of a mango leaf. 

The earlier fossil records of mango (Mangifera indica) from the Northeast and elsewhere were 25 to 30 million years old. The 'carbonized leaf fossil' from Damalgiri area of Meghalaya hills, believed to be a mango tree from the peninsular India, was found by Dr R. C. Mehrotra, senior scientist, BSIP and his colleagues. 

After careful analysis of the fossil of the mango leaf and leaves of modern plants, the BISP scientist found many of the fossil leaf characters to be similar to mangifera.

An extensive study of the anatomy and morphology of several modern-day species of the genus mangifera with the fossil samples had reinforced the concept that its centre of origin is Northeast India, from where it spread into neighbouring areas, says Dr. Mehrotra. 

The genus is believed to have disseminated into neighb…
