Progress report for WRGR22-003
Project Information
As agriculture continues to develop in the market, it becomes more recognized as more than just farming. Aside from production activities such as growing crops, it also involves processing and marketing activities such as safe handling of agricultural products and transforming them into value-added products. According to Marketing Resource Center (2020), value-added products are transformed from raw agricultural products. Like every other country, Guam experienced interruptions in the food supply chain due to the COVID-19 pandemic, emphasizing the importance of locally produced foods regarding food security and sustainability. This involves utilizing locally grown products to produce viable value-added products, which can target market expansion and open up opportunities for more income and potential export opportunities for Guam.
In the past few years, Guam has experienced tremendous growth in dragon fruit production, a high-value crop, by subsistence and commercial farmers. This project seeks to develop a dragon fruit association that will assist dragon fruit growers in producing, marketing, or selling their products. It also aims to educate safe handling methods aligned with Good Agricultural Practices (GAP) and food preservation. Research on market development will create marketing strategies tailored to Guam’s consumer demand for agricultural products and value-added products. Furthermore, this project can provide the capacity to access adequate food for subsistence in times of emergencies and promote sustainable viability for the agricultural community.
Objective 1: Develop and expand agricultural marketing channels.
To enhance the knowledge and sharpen the skills of local producers, farmers will be acquainted with key model strategies for (1) understanding the marketplace and customer needs, (2) designing a value-driven marketing strategy, (3) constructing an integrated marketing program, (4) engaging customers and developing customer loyalty, and (5) generating profits and establishing a strong corporate presence (Armstrong & Kotler, 2016).
Objective 2: A greater presence for value-added production and local food systems.
Developing a reputation for quality and extending the sales and distribution network for entrepreneurship, an association for Dragon-Fruit Farmers will be inaugurated to promote its advantages of nutritional quality, sensory attributes, and storage stability, upon which value-added products, such as dragon fruit jelly, can be derived for easy storage and transportation.
Objective 3: Position local marketing with good agricultural, handling, and labeling practices.
Incorporating farm-business practices into marketing techniques involves handling the product, communicating between farmer-and-consumers, and crop diversity or specialization. Partnering with different organizations, discussions will include harvest and post-harvest handling, quality, service, and payment methods critical to production consistency and supply (Hall, 2002).
Objective 4: Market food processes and techniques to producers to expand consumer choices, foster food system stabilization, and extend the availability of seasonal produce.
Information placement will facilitate potential in marketable options for food processing and the impact on local food systems. This is an interlinking extension on the prior project objective (SW09-067) to market several advantages, including food safety, preserved nutritional value, consumer convenience and economies of scale, and diversity in seasonal availability (Van Boekel et. al, 2010, pp. 1217, para 2).
Located in the Western Pacific Ocean in the center of the Asia-Pacific region, the island of Guam has always been reliant on the import of commodities. Imported products include foods such as fruits, vegetables, and pastries. Unfortunately, for many years, the island’s import of foods and non-alcoholic beverages exceeds its exports, indicating a trade deficit in this specific commodity group. The agricultural industry in Guam has faced many adversities such as lack of natural resources, inclement weather such as typhoons, and the COVID-19 pandemic from which Guam’s farmers and farm workers remain resilient. However, another challenge that the industry faces is a lack of resources and support to strengthen the island’s agricultural marketing. This project explores potential opportunities to assist in Guam’s agriculture marketing development. This will offer many benefits to local producers on the island, such as strengthening the island’s food safety, expanding food preservation through value-added products, and the opportunity to earn more profits, which were identified as areas warranting additional studies in a previously completed Western SARE project (SW09-067) (Barber et al., 2012). It assisted in exploring market channels for Guam’s tourists for locally produced foods and developing the Guam Farmer Chef initiative that assisted in strengthening the diversity of enterprises for the island.
This study is connected to the previous project (SW09-067) aiming to improve Guam’s agricultural marketing by offering educational workshops that will (1) help prepare local producers for certifications in areas such as food labeling, (2) offer workshops that acquaint local producers with skills on food safety based on Good Agricultural Practices and Good Handling Practices, and (3) expand Guam’s farmers’ consumer base and their profitability by developing value-added products from locally produced foods, which can also open export opportunities for the island.

Education & Outreach Initiatives
We aim to conduct trainings on Good Agricultural Practices (GAPs) and Good Handling Practices (GHPs) to local farmers/producers (Obj. 3) in Fall 2024.
Adhering to Good Agricultural Practices (GAPs) and Good Handling Practices (GHPs) allows farmers to provide safe, high-quality produce items on the market, increasing the likelihood of retailers and consumers to purchase farmers’ produce and provide farmers with profit. Thus, evidence-based trainings from a certified instructor will be provided to local farmers. Topics will include but are not limited to harvesting procedures, washing/sanitation procedures, optimal storage conditions, transportation guidelines, and pest control procedures. Certificates will be provided to participants who successfully finish the trainings to provide credibility of their farming practices, thus improving the appeal of their products to local consumers and retailers.
1. Dr. Jian Yang, professor of food science, provided educational presentations on proper post-harvest handling, storing, and shipping of dragon fruit at the value-added products workshops on August 9, 2024, and September 28, 2024.
2. Sophie Santos, research assistant, provided the simplified poster presentation on optimal post-harvest and storage conditions at the 2024 Guam AgrAbility Regional Conference in Guam on October 29, 2024.
3. Information presented included the following:
• Optimal conditions for dragon fruit cultivation
• Harvesting procedures, including harvest indices
• Storage, including common storage issues and optimum storage conditions
• Post-harvest handling, including a post-harvest handling flowchart
4. Both local farmers/growers and consumers, as well as academic scholars, gained knowledge of proper dragon fruit cultivation and handling, thus effectively disseminating dragon fruit cultivation knowledge to local and international stakeholders.
We aim to conduct a market analysis of various dragon fruit value-added products to estimate their success on the market (Obj. 2) in Summer 2024 and Spring 2025.
When conducting workshops on value-added products for dragon fruit, it is important to establish whether the products will perform successfully on the market for the sake of the farmers’ and producers’ financial profits. Before the value-added product workshops are conducted, a market analysis of various developed value-added dragon fruit products will be conducted. A questionnaire/survey will be administered to at least 30 consumers which will show them value-added dragon fruit products and ask them how likely they are to purchase or how much they will be willing to pay for these products. Collected data will be analyzed, and the recipes of the 5 value-added products that are projected to be most successful will be taught in the value-added products workshop.

We aim to conduct workshops that teach local farmers/producers how to create and successfully market value-added dragon fruit products (Obj. 1, 2, 4) in Fall 2024 and Spring 2025.
Using the results of the previously conducted market analysis, this series of workshops will teach farmers/producers/small businesses how to make selected value-added dragon fruit products. This workshop will also serve to educate participants on crucial marketing strategies. Workshops will begin with an informative, engaging lecture that provides participants with easily comprehensible marketing strategies and tips (e.g., labeling, packaging, etc.) so they can maximize profit from their dragon fruit. Then, participants will join in a facilitated hands-on cooking demonstration paired with taste testing that will show them examples of value-added dragon fruit products and their potential appeal. Additionally, this hands-on cooking demonstration will also teach participants how to extend the shelf-life and availability of seasonal dragon fruit produce by presenting shelf-stable dragon fruit products.
1. As of January 1, 2025, 5 value-added products (jam, jello, freeze-dried dragon fruit, gummies, and nectar drink) from dragon fruit have been developed. The three products presented in the workshops were dragon fruit jam, gummies, and nectar drink.
2. Dr. Jian Yang and Sophie Santos presented information on value-added products of dragon fruit at the value-added products workshops on August 9, 2024, and September 28, 2024. Dr. Tanisha Aflague presented information on nutritional value and benefits of dragon fruit on August 9, 2024.

Project Outcomes
August 24, 2023 - International Agricultural Research Exchange Symposium conducted by the Grant PI and Co-PI at the University of Guam. The topics include food science (e.g., dragon fruit value-added products), food chemistry, crop production, cultivation management, tissue culture, plant pathology, hibiscus sabdariffa, farmer/producer stress, etc. The participants include 15 students (undergraduate and graduate agriculture majors) and 10 faculty members from the University of Guam and the National Pingtung University of Science & Technology in Taiwan, as well as 3 local farmers. The purpose of this symposium is to share research ideas and engage farmers with field specialists in food science and agricultural production.
September 4, 2023 - Local farm visit conducted by the Grant PI. 10 students (undergraduate and graduate agriculture majors) and 3 faculty members from the University of Guam and the National Pingtung University of Science & Technology in Taiwan will visit 3 local dragon fruit farms located in Inalåhan (Southern Guam), Yigo (Northern Guam), and Dededo (Central Guam). The purpose of this visit is to establish relationships with dragon fruit farmers and discuss current value-added product development.
August 9, 2024 - A workshop on dragon fruit value-added product development was conducted by the Grant Co-PIs at the University of Guam. The session focused on food innovation, processing techniques, and consumer preference research. Participants included 12 undergraduate agriculture students, 5 local producers, and 2 extension agents. Attendees gained hands-on experience in producing dragon fruit jams, sorbets, and dried snacks, with follow-up plans to apply these techniques in community outreach.
September 28, 2024 - The Grant Co-PI presented on dragon fruit product development during a community outreach event in Dededo. This event engaged over 30 community members, including farmers and youth, highlighting the market potential of value-added products and promoting local food entrepreneurship.
October 29, 2024 - At the 2024 Guam AgrAbility Regional Conference, the Grant Co-PIs and team presented research findings and demonstrated value-added product prototypes developed through the WSARE-supported project. The audience included more than 185 participants, such as farmers, extension educators, and representatives from regional agricultural organizations. The presentation strengthened farmer interest in diversifying dragon fruit-based offerings and led to follow-up discussions on collaborative product testing.
These activities increased participant knowledge in value-added agriculture, encouraged farmer-student collaborations, and supported the ongoing development of local agribusiness models centered on dragon fruit innovation.
