4 Presenting the Program Welcome (5 minutes) Slide 1: Note: As participants arrive, direct them to put on an apron, pull back long hair, and wash hands in preparation for the training session. Welcome I am so glad to have each of you join us for our Food Preservation: Dehydrating program. This program will provide an overview and practical application of research-based methods for dehydrating foods. Icebreaker (5 minutes) Slide 2: Please share your name, favorite dried food and experience level with dehydrating. Note to Facilitator: Be prepared to share your own personal experiences with dehydrating. Remember to introduce your assistant and any volunteers who may be assisting you during the program. Program Introduction (2-3 minutes) Slide 3: People have been preserving food through drying for thousands of years. Dried food yields maximum quantity for the least volume, which makes dried foods very popular among hikers and campers. Today, more people are eating dried food as a healthier snack alternative to candy and chips. Dried foods can be stored for longer periods without spoilage. It makes good economic sense too. This program has been designed to teach general techniques and guidelines for drying fruits and vegetables at home. Your publication also provides two tables on drying particular fruits and vegetables. Objectives (2-3 minutes) Slide 4: Participants will: 1. Identify research-based methods for dehydrating foods at home. 2. Differentiate between different drying methods and the pros and cons of each method. 3. Examine and utilize equipment and tools for dehydrating. 4. Observe the correct process for preparing various food products for dehydrating. 5. Examine dehydrated food products to determine dryness. 6. Observe methods for conditioning, pasteurizing, packaging and storing dehydrated foods. 7. Discuss the nutritional value of dried foods and how to best use dried foods at home. Program Outline Pretest (10 minutes) Slides 5-13: Distribute pretest to participants. Allow approximately 5 minutes for completion and review answers. Activity 1 Pros and Cons of Drying Methods (Objectives 1, 2 and 3) (10 minutes) Slides 6-13: Provide an overview highlighting pros and cons of the various drying methods as outlined below and in the Facilitator Guide: sun, vine, microwave, oven and dehydrator. Display and explain the use of all tools and equipment for each type of drying. Activity 2 Food Preparation for Dehydrating (Objective 4) (30 minutes) Slides 14-34: Demonstrate how to prepare fruits and vegetables for dehydrating. Explain the importance and demonstrate some of the methods for pre-treatment of fruits and vegetables prior to dehydrating. Also demonstrate how to prepare herbs for dehydrating. 4

5 Activity 3 Checking for Dryness (Objective 5) (10 minutes) Slides 35-37: Have dried samples to demonstrate how to check for dryness. Have correctly dried and incorrectly dried samples of fruits, vegetables and herbs, for participants to examine. Activity 4 Preparation for and Storage of Dehydrated Items (Objective 6) (10 minutes) Slides 38-42: Demonstrate how to condition dried fruits, how to pasteurize dried items and correct methods for packing and storing dried foods. Emphasize the importance for uniform thickness and size of pieces of fruits and vegetables when beginning the drying process. Activity 5 Nutritive Value and Use of Dried Foods (Objective 7) (10 minutes) Slides 43-44: Share the nutritional value of dried foods as compared to fresh, canned and frozen foods. This information is noted on the Program Facilitation Script and in the Publication. Demonstrate how to reconstitute dried foods; share samples of dried fruits as a nutritional snack; provide examples of how to use dried foods in recipes at home. Activity 6 Hands-on Activity Drying Apples and Making Fruit Leather (Objectives 3, 4 and 5) (60 minutes) Slide 45: Direct participants to divide into small groups to correctly sequence the cards in the sequencing activity. Review the correct order for the cards, as outlined in the publication. Clarify any concerns or misunderstandings resulting from the sequencing activity. Direct small groups to work at one of the stations, prepare apples for dehydrating and prepare a simple fruit leather recipe.

Evaluation and References (10 minutes) Slides 47-49: Distribute evaluations and ask participants to complete and return prior to leaving the program. Obtain or mailing addresses for follow-up evaluations. Please explain to participants the importance of completing program evaluations. The following items outline the importance of evaluation for this particular program: If program objectives were met If information presented in the program was easily understood If the method of presentation helped you easily understand and learn what was presented If the information presented was what you really needed to make a difference in your life If the knowledge you ve acquired has positively impacted your life If we are using the best methods and strategies to evaluate our programs 5

6 If we are using the best methods and strategies to communicate program offerings to community members If participation in programming has an impact on long-term behavior changes To help us improve future programs and revise current programming Invite participants to sign-up for other UK CES programs. Distribute newsletters (4-H, FCS, Ag etc.), program invites, informational materials, etc. promoting UK CES programming. Sample Success Story: County Family and Consumer Sciences Extension Agent collaborated with 4-H and KEHA leaders to offer Food Preservation Workshops to a total of 45 participants. Eighty percent of participants identified research based methods of home food preservation as a result of the program. Seventy-five percent of participants identified various methods for dehydrating foods. Ninety percent of participants accurately prepared food products using one method of drying foods to preserve those items. Eighty percent identified ways to detect moisture or spoilage in home dried foods. A three month follow-up evaluation revealed that sixty-five percent of participants utilized the research based method of dehydrating to safely preserve harvested foods from home gardens utilizing skills learned from the program. A follow-up program is being planned to offer additional food preservation programming. After the Program Reflection: Presenters, please document strengths and weaknesses of program for future improvements. Note additional needs, props, etc. Incorporate participant ideas to refine program for future presentations. Note tips and ideas for the next presentation of this program.
