About this Research Topic

Background

Improving crop quality and shelf-life is a challenge in the context of a global horticultural food supply. Horticultural crops are an important source of carbohydrates, proteins, organic acids, vitamins and minerals for human nutrition and health. In addition to the health benefits that can be derived from their consumption, fruits and vegetable also function as precious sources of bioactive compounds for food functionalization or nutraceutical preparations. To improve quality and reduce losses, producers and handlers should understand the biological, environmental, and technological factors affecting quality and deterioration. Fresh horticultural products are living tissues subject to continuous changes after harvest as they are high in water content and, for that reason, are subject to weight loss and mechanical injury. Horticultural commodities are perishable products with an active metabolism, subject to extensive losses through microbial decay, physical injury and senescence during postharvest life. Postharvest changes in horticultural products cannot be stopped, but they can be slowed within certain limits. The maintenance or improvement of the postharvest life of fresh horticultural products is becoming increasingly important. Indeed, appropriate preharvest techniques and postharvest handling and technology play a key role in increasing food availability and maintaining food quality. Fresh horticultural products are different in terms of morphological structure (roots, stems, leaves, flowers, fruits, etc.), composition, and general physiology. For that reason, commodities requirements and recommendations to maintain quality and improve postharvest life vary among products. The connection between quality build-up in the preharvest period and its impact on the technological quality traits have been frequently overlooked and detailed knowledge is still missing. During postharvest life, as maturation progresses, genetic, chemical and environmental control can help to maintain product quality. Improving shelf life, maintaining quality, and reducing waste while reducing the use of chemicals are mandatory to meet the consumer's demand and reduce losses along the food chain.
It is very important to highlight the most significant changes occurring during maturity-ripening as pre-harvest and post-harvest factors affecting fruit and vegetable quality at harvest time. Preharvest growth and development is a critical period for the formation of the quality and resistance of horticultural crops (products), and most pathogens remain quiescent for a long time in this period. The main pre-harvest factors influencing quality are related to environmental factors, such as light, temperature, rainfall, soil, and cultural practices, including the use of suitable cultivars, fertilization, irrigation, pruning, spraying, etc. The main post-harvest factors influencing quality of fruits and vegetables are genotype, maturity stage, harvest (method and time), and the applied technologies that affect the conditions during postharvest chain (sorting and grading, packaging, storage, and transportation).
The aim of this Research Topic is to highlight and describe recent and advanced research regarding pre-harvest and postharvest factors and technology that affect horticultural product (fresh and processed) physiology, quality and shelf-life. In order to understand the effects of preharvest and postharvest factors on the postharvest quality, disease, maturity, senescence, and shelf life of horticultural crops, this Research Topic will collect the relevant research papers related to this topic.
Potential topics to be covered:
• Advanced agronomic practices to enhance quality and shelf-life of fruits and vegetables.
• Advanced technologies to enhance quality and shelf-life of fruits and vegetables.
• Advanced technologies to enhance and to check safety, health, and sustainability of fresh and minimally processed fruits and vegetables.
• Fresh and minimally processed products physiology and technology and factors that affect quality and shelf-life.
• Controlled and Modified atmosphere packaging (MAP) application and composition.
• Methodologies and technologies for edible coating production and application on fresh- and minimally processed horticultural products.
• Effect of harvest, handling, processing, storage and distribution on quality, nutritional and nutraceuticals parameters.
• Factors that affect quality losses and waste during food chain.
• Microbiological analysis of fresh- and minimally processed products, effect of anti-microbial agents on microbial load and products safety.

Authors are invited to submit recent research regarding pre-harvest and postharvest factors and technology that affect horticultural product (fresh and processed) physiology, quality and shelf-life.
Please note: Descriptive studies that report responses of growth, yield or quality to agronomical treatments will not be considered if they do not progress physiological understanding of these responses.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?
