Food Storage Survey Results

Thanks to all of those who took the time to respond to the food storage survey several weeks back.  The information you provided has been really helpful.  A clear desire for additional programming in this area was expressed, and I’ll be working to develop that.

Here are the survey result highlights:

  • 82% of respondents expressed interest in a formalized course on food storage topics with the overwhelming majority preferring classroom / workshop format and/or a webinar.
  • 66% of respondents have plans to expand your food storage capacity in the next 24 months.
  • While most respondents expressed concern about the utility costs of their storage systems, relatively few (37%) currently know those costs.
  • 60% are storing in multiple zones (Temp and RH), but the overall knowledge of optimal storage conditions is relatively low (see related post on USDA Handbook 66).
  • Winter markets included (% reporting sales to each)
    • Wholesale (74%)
    • Retail (41%)
    • Farmer’s Markets (41%)
    • Winter CSA (38%)
  • The most common systems in use are (% reporting use):
    • Walkin cooler (57%)
    • Chest freezers (55%)
    • Heated Winter Storage (39%)
    • Root Cellar / Other Cool Storage (not refrig’d) (31%)
    • CoolBot(TM) (28%) – CoolBots(TM) website
    • Walkin freezer (16%)
    • Other cooler refrigerated (16%)
  • Other areas where respondents expressed interest in learning more included:
    • basic refrigeration principles / fundamentals
    • equipment overview
    • construction how-to
    • general post-harvest handling best practices
    • insulation trade-off / bang for your insulation buck
    • building in resilience / what happens when the power goes away?
    • making better use of cold winter air and thermal storage
    • how to best segment a walkin / zoning the storage space
    • short vs. long term storage practices
    • economics; what is this actually costing me now and in the future?
  • When asked about their own lessons learned, respondents noted:
    • Get field heat out quickly and keep it cold
    • Excellent storage is key to having excellent product
    • Insulate, insulate, and then insulate some more
    • Measurement of temperature (and RH) is critical, don’t assume you are hitting your target conditions
    • Watch out for ethylene off-gas from, e.g., apples
    • Climate change is impacting harvest timing and therefore marketability and storage needs
    • Plan for power loss
    • Insure your product for loss while in storage
    • Build bigger than what you presently need. Coolers and freezers are quickly outgrown.
    • Consider “keeping it on the hoof” instead of harvest and storage.
    • Pre-sell – grow only what you know you can sell – Sales and product movement are critical.  Do the pre-planning.
