Storing Chocolate and Its Shelve Life.


Yesterday, I received a question about a blog we posted July 12, 2012 on storing chocolate  .  “Any update on vacuum sealing the chocolate?” With the possible shortage of chocolate the news has been talking about and if one person has a question I am sure more do, it is time to do an update.

Several months prior to the July 12, 2012 blog my wife vacuum sealed several jars of chocolate.  About two weeks ago she opened one of the jars to make a big batch of cookies for an activity.  The chocolate tasted and looked normal.  This was unsweetened chocolate chips.  On several prior occasions, she has used some.  The jars were opened and then resealed.  So far all of it has been good.

We still have some more jars and will update this in the future.  The jars were quart jars vacuumed sealed with a FoodSaver.  Here is a link to a demonstration my wife did with one,  See my Wife’s FoodSaver Demo.  

They are easy to use and do a good job of extending the shelf life of many products.

Hope this answers your question.

  1. As a young Marine I hoarded the “tropical chocolate bars” which occasionally came packed in the “Ration, Combat, Individual” of the Vietnam era. My father told me that during WW2 in the Pacific Theatre that tropical chocolate bars were valued as a treatment for the type of dysentery which unfortunately becomes frequent during field operations when mess gear is improperly sanitized. The correct method for cleaning mess gear in the field is contained in

    An interestig historyn of the tropical chocolate bar is on the Hershey company archive at

    A noteworthy description of the C-Rat choclate bar is:

    “The standard chocolate bar, which melted readily in summer heat could never be adapted to being carried in a soldier’s pocket. In addition, it was thought to be too tempting in taste to be used as an emergency ration to be eaten only when on the verge of starvation. Captain Logan explained his requirements: a bar weighing about four ounces, able to withstand high temperatures, high in food energy value, and tasting just a little better than a boiled potato.”

    I can testify personally to its lack of excitment, when eaten alone, however, when combined with the instant coffee packet, sugar packet, and non-dairy cream substitute which comes in the C-ration, and crushed into a canteen cup of boiling water heated with shavings of C4, when the monsoon rain is running off your M1 helmet and under the neck of your poncho, when you are hunkered down in your 81mm mortar pit, in the dark, is pure heaven!

    The Hershey narrative continues on:

    ” It has been estimated that between 1940 and 1945, over three billion ration units were produced and distributed to soldiers around the world. In addition to the individual bar, Hershey Chocolate produced a three pack of the four ounce bars intended to furnish the individual combat soldier with the 1,800 calorie minimum sustenance recommended each day.
    In 1943, the Procurement Division of the Army inquired about the possibility of obtaining a heat resistant chocolate confectionery bar with an improved flavor. After a short period of experimentation, Hershey’s Tropical Chocolate Bar in both one and two ounce sizes was added to the list of war production items. This bar was destined to exceed all other items in the tonnage produced and along with the Field Ration D bar, became part of Hershey Chocolate’s history. In July of 1971, Hershey’s Tropical Chocolate Bar went to the moon with Apollo 15 astronauts.”

    Thanks for the memories!
