Storage & Preservation of Produce & Cheese

Last week, a reader asked about veggie and cheese storage, expressing the concern that these perishables often spoil before they can be used. That concern is shared by many. Annually, in Canada and the U.S., several million tons of food is thrown away. At a cost of several hundred dollars, on average, per household, these statistics are alarming. Two rules of thumb can alleviate much of this waste.

  1. When it comes to shopping for perishables (particularly produce,) buy only what is needed and can be consumed in a few days. This may mean more frequent visits to the grocery store, but you'll enjoy fresher produce and avoid spoilage of a stockpile. Most produce requires a cool atmosphere and a fridge not filled to capacity actually works more efficiently, allowing internal air to circulate better and preventing pockets of cooler or warmer air from forming. Those over-chilled or -warm conditions can be very detrimental to the longevity of both produce and cheese.


  2. When storing perishables, avoid washing them until they are to be used. Many vegetables and fruits have natural oils or have been sprayed with protective (and neutral) waxy coatings which help preserve them. Washing removes those oils and/or coatings, making the produce much more vulnerable to spoilage. If the product has excessive dirt on it, simply brush the soil from it with a soft cloth and then store. When ready to use, the produce can be washed. Check out this very informative article Fruit & Veggie Washes by "The Grocery Bags," Anna Wallner and Kristina Matisic. Their findings support my own experience.


Though these two rules will help avoid most produce spoilage, there is another concern when storing fruit and vegetables and that is whether the product needs to be stored in the fridge, at room temperature, with ventilation or without, or in darkness. While researching this, I came across an excellent article on SparkPeople which included this comprehensive and easy to read chart: Fruit & Veggie Storage Chart .

When it comes to cheese, the situation is not as clear. Some argue cheese needs an airy environment, while others argue ventilation is death for cheese. It turns out, both are true. It depends on the cheese, which is a living food, much like yogurt. During research, I found an article – directed towards food service professionals (recommendations by The Wisconsin Milk Marketing Board and Wisconsin Cheese Makers,) – which answers this question, in all its complexity: Cheese Storage Tips.

I've heard other tips on preserving foods, but none of them have proved successful for me. One such recommendation says: to preserve bananas' freshness, they should be separated from the bunch. I ran three experiments on this suggestion, using three different bunches of bananas in varying weather conditions. In each experiment, I separated a few of the bananas from the bunch, and left the remaining bananas attached. Each time, all bananas, whether separate or attached, appeared to mature at the same rate, and their taste confirmed this. We do live in a very arid climate, so I'm not sure if this skewed the results or not. You might wish to perform your own experiments.

One handy hint I learned from my mother is to freeze produce that is deteriorating, but not yet spoiled, and use those veggies in a stock. The flavours may not be as high as fresh vegetables would produce, but those wilted products won't be thrown into a landfill where they'd be completely wasted. A compost pile is another good place for (most) produce that has passed its prime.

If you have ideas or suggestions you wish to share on this subject, please leave a comment.

Whole Goodness

Whole foods are generally considered to be foods which have not been chemically or genetically treated, foods that are natural and in the raw state, and have not been pared, polished, or otherwise processed. While organic foods are becoming increasingly popular, I have not included that criterion in the following article simply due to their greater cost. Some may argue (as I have with a certain cheese) that organic foods have value and thereby bridge the cost-to-savings ratio.

Perhaps one of the best ways to save money on the grocery budget is to buy foods whole. Savings are only part of that equation, though. Whole foods, in many cases, offer better flavours and, in some instances, higher nutritive values and/or improved quality over their processed alternatives.

Here are some examples:

  • Spices: Nutmeg, peppercorns, coriander, mustard and allspice are a few examples of spices that can be bought in their whole form. The seed is nature's way of sealing in essential oils and flavonoids. By grinding or grating them, as needed, fragrance and flavours are significantly enhanced, and that does wonders for any dish they're seasoning. Some roots (e.g. licorice) and barks (e.g. cinnamon) also retain more of their goodness but can be hard to process without an electric grinder. A mortar and pestle work well for most seeds, nuts, and leaves, though, and allow you to control the grinding process for the perfect texture and/or consistency.
  • Ground Meats: With all the recalls and salmonella scares over the last few years, we've begun buying whole cuts of grass-fed, free-ranged beef (and fresh turkey) and grinding at home. Our savings aren't significant, but we have greater peace of mind knowing the ground beef comes from one animal and does not include questionable-meat "trimmings." ('Grassfed' beef article & recipes) To save on the purchase of suet, we buy whole chuck, which has a good amount of fat. Any excess can be trimmed, but we seldom find that necessary. Another benefit of buying whole meats and processing them at home is that it allows you to apportion package sizes to suit your family's needs.
  • Cheese: Pasta and pizza just wouldn't be the same without Parmesan. The popular processed varieties are easy to use, but their flavour, smell, and texture can be off-putting. We purchase blocks of Parmigiano-Reggiano – the "King" of cheeses – and grind or slice it as needed. Much like spice, this fresh-grated cheese has better flavour and fragrance. There is little, if any, saving when buying this brand over the processed but the culinary value, for us, is significant. That and fresh Parmesan actually melts on a pizza!
  • Fruits and Vegetables: Probably one of the best ways to economize a grocery budget is to buy produce whole. Pared fruits and vegetables cost much more, suffer vitamin degradation, and many are chemically treated to enable longer shelf-life as most processed produce will spoil faster. (Ontario government: Minimally-processed fruit & veg, risk assessment) Processed fruits and vegetables are more susceptible to pre-purchase contamination, also. Whole produce may require a little more preparation time (re: paring and/or peeling,) but their trimmings have value in a stock pot or compost pile. Both "free" veggie stock and rich loamy soil have real worth, too.
  • Coffee: Budget may be the last thing on your mind when reaching for that morning cup o' Joe, but this is another way to stretch your grocery dollars. Pound for pound, coffee beans are (generally) less expensive than most ground varieties. As with spices, the coffee bean is a tidy little flavour packet that, when ground fresh, offers significantly enhanced flavours...not to mention, caffeine punch.

Aside from budgetary issues, we buy whole foods because we prefer the taste and aroma. Purchasing fruits, vegetables and meats whole has also spared us from many of the Salmonella, E. coli and Listeria outbreaks in recent years.

If you're concerned about your food's goodness, consider purchasing whole foods. The economic gain will be a cherry on top!
