Description

PepsiCo seeks an innovative technology capable of evaluating potatoes for either internal defects or sugar content. A process capable of combining both analyses would be ideal.

 

Background

src=/documents/6768284/15407958/potato+chips+small.png/350ea81f-98f8-4b60-840e-05f04605fd4d?t=1466168943427In order to increase the efficiency of our potato processing lines, PepsiCo is interested in technologies capable of evaluating, in a non-invasive manner, potatoes for their sugar content and for possible internal defects such as hollow-heart, green internals, stones, etc.

 

The ability to detect these attributes in whole/un-sliced potatoes will allow PepsiCo to deliver a higher quality potato chip to its consumers.  For example, by removing potato defects prior to slicing and frying, the energy and cost associated with converting a defective potato into a defective fried potato chip will not be wasted.  Furthermore, by knowing the potatoes’ sugar content prior to frying, the specific ‘fry profile’ (e.g. oil temperature/dwell time) can be optimized for the specific potatoes being fried.

Key success Criteria

PepsiCo is interested in technology(s) that meet the criteria for one, or both, of the below-described sensors.  For example, a technology that can meet the must-have criteria for the sugar sensor, but not for the defect sensor, is still of interest.

 

SUGAR SENSOR:

 

Must-haves

  • Determine if potatoes have more or less than 0.03% glucose (with 95% accuracy)
  • Deployable to either a manufacturing facility and/or a farm (e.g. robust)
  • Able to handle chipping potatoes, typically 2.5”- 5” in diameter
  • Minimally-invasive measurement.  The potato that is tested cannot be scrapped (it must become an edible chip after testing)
  • Line-of-sight to a $50,000/unit final, installed cost.  Prototype units could be more expensive.
  • Minimum of 1,000 potatoes measured per hour

Nice-to-haves

  • Determine sugar levels in potatoes to ±0.005% for all sugar types (glucose, fructose, sucrose, etc.)
  • Remove potatoes with sugar levels that are above 0.03% glucose
  • Entirely non-invasive measurement.
  • Regarding high-sugar potatoes: <1% incidence of false-positives
  • Small footprint (ideally less than 2’ x 2’ x 2’)
  • Should not require a high level technical expertise to operate
  • 100% inspection rates (30,000 – 40,000 lb/hr of potatoes).
  • Also detect amino acids, with a limit of detection ≤1000 ppb.

 

DEFECT SENSOR:

 

Must-have

  • Detect at least 80% of defective potatoes and remove them from the processing stream.
  • Deployable to either a manufacturing facility and/or a farm (e.g. robust)
  • Able to handle chipping potatoes, typically 2.5”- 5” in diameter
  • Minimally-invasive measurement.  The potato that is tested cannot be scrapped (it must become an edible chip after testing)
  • Line-of-sight to a $50,000/unit final, installed cost.  Prototype units could be more expensive.
  • 100% inspection rates (30,000 – 40,000 lb/hr of potatoes).

Nice-to-haves

  • Entirely non-invasive measurement.
  • Regarding defect rejection: <1% incidence of false-positives
  • Detect and remove internal defects
  • Small footprint (ideally less than 2’ x 2’ x 2’)
  • Should not require a high level technical expertise to operate

 

Possible Approaches

With the exception of the technologies described below, PepsiCo is interested in any technology capable of reaching the performance goals set forth here.

 

Approaches not of Interest

Technologies that have been previously investigated are listed below.  Significant improvement beyond PepsiCo’s current understanding of the technologies capabilities would be required to pursue any submission in these areas.  Data collected on actual potatoes is an excellent way to demonstrate “significant improvement.”

 

  • Cost:
    • X-ray
    • Gas Chromatography-Mass Spectrometry (GC-MS)
  • Insufficient Limit of Detection:
    • Visible-light/Infrared/UV/Raman methods, including optical re-formatting and filtering techniques
    • Hyperspectal methods
    • Capacitance/electrical impedance
    • Polarimetry
    • Ultrasound
    • NMR/MRI methods
    • Thermography
    • Microwave and radiowave
    • Laser-induced breakdown spectroscopy
  • Concerns about ability to sample at scale:
    • Photoacoustic methods
    • Optical Coherence Tomography
    • Polarimetry
    • Gas Chromatography-Mass Spectrometry (GC-MS)
    • Glucose Test Strips/Blood Glucose Monitors (enzymatic and non-enzymatic)
  • Invasive: 
    • Glucose Test Strips/Blood Glucose Monitors (enzymatic and non-enzymatic)
