PURE Bioscience Provides Update: Expanding Use of PURE Control® Antimicrobial in Produce Processing; Expanding Use of PURE® Hard Surface Disinfectant

SAN DIEGO–(BUSINESS WIRE)–$PURE #PURE–PURE Bioscience, Inc. (OTCQB:
PURE), creator of the patented non-toxic silver dihydrogen citrate (SDC)
antimicrobial, provided an update on the expanded use of FDA
approved PURE Control® antimicrobial for application directly onto
produce during processing and the expanded use of PURE Hard Surface
disinfectant.

PURE Control – Produce Update

The first customer for PURE Control, Taylor Farms, is North America’s
largest supplier of salads, fresh-cut vegetables and healthy fresh
foods. It serves leading customers in the foodservice, retail produce,
and retail deli segments of the fresh business.

• In the fall of 2017, Taylor Farms began a pilot test applying PURE
  Control as an added intervention step on one processing line in its
  Salinas, CA, plant to eliminate pathogens causing foodborne illness,
  including E. coli, Listeria, and Salmonella.
• The processor conducted extensive use validation studies (including
  efficacy and organoleptic), on the way to evaluating the use of PURE
  Control in its US processing plant network.
• Processors typically seek a 1 log reduction* in pathogens from an
  intervention or processing aid. Testing at produce processors,
  including Taylor Farms, consistently exceeded expectations, indicating
  pathogen reductions averaging 3 logs – or 99.9%.
• Earlier this month, Taylor Farms expanded its use of PURE Control to a
  second line in the first plant, initiated installation on multiple
  lines in a second plant in Salinas, CA, and developed plans to expand
  to a third plant in calendar Q2. These plants supply produce to
  leading foodservice chains as well as to retailers.

*Log reduction is a mathematical term used to show the relative
number of live microbes eliminated from a surface by disinfecting or
cleaning. A 2-Log reduction can be best illustrated as having two zeros,
meaning the number of germs is 100 times smaller.

A growing number of produce processors continue to be in various stages
of testing PURE Control, and testing results to date have been positive.
These processors supply fresh and/or frozen produce. The sales cycle for
PURE Control for each customer will continue to involve varying amounts
of validation and optimization testing by those customers.

The Company estimates that sales of PURE Control to the average produce
processing plant can generate approximately $1 million in annual sales
per plant/year.

Expanding Use – PURE Hard Surface

Food Transport

• As previously announced, PURE’s new truck sanitization solution (using
  PURE® Hard Surface disinfectant) is being rolled out by one of the
  largest foodservice distribution companies.
• Several other large food transport companies are in various stages of
  testing.

Restaurants

• Beginning early in calendar Q2, use of PURE Hard Surface will be
  rolled out by a blue chip national casual dining chain.

Processing/Manufacturing

• In addition to PURE Control, Taylor Farms has been PURE’s leading
  adopter of PURE Hard Surface for environmental and surface
  disinfection in its processing plants, and is currently using it in a
  growing majority of its 14 plant network. Within each plant,
  additional applications are being added regularly (including the
  Company’s food transport sanitization solution).
• The Company continues to on board additional food
  processing/manufacturing plants (most recently two household name
  national brands) while expanding applications within its customer
  portfolio of 70+ food processors.

Hank
R. Lambert, CEO of PURE, said, “While slower than first anticipated,
the validation that comes from industry leading Taylor Farms expanding
the use of PURE Control gives us confidence that our revenue growth will
accelerate. We believe this is the start of our meaningful penetration
into the $300+ million US produce processing aids market.

“In addition, because of Taylor Farms preeminence, we believe its
validation of PURE Control will encourage others in the produce
processing industry to move more quickly.

“We are also encouraged by the growing momentum for PURE Hard Surface
among food transport companies, food processors and restaurant chains,”
concluded Lambert.
