Introduction
Stone fruits—apricot, plum, and cherry—are pivotal in agriculture and the food industry due to
their high nutritional properties (vitamins A, C, E, antioxidants, dietary fiber, potassium,
magnesium) and versatility for processing into various products, making them highly sought
after in local and international markets. In Uzbekistan, stone fruit processing is a key
agricultural sector, with regions such as the Fergana Valley, Samarkand, and Surkhandarya
producing over 100,000 tons of processed products annually (Uzbekistan Statistics Agency,
2024).
Stone fruit processing in Uzbekistan is regulated by a robust legal framework. The Law of the
Republic of Uzbekistan “On Food Safety” (2021) mandates compliance with microbiological
and chemical safety standards and sanitary norms. The Law “On the Development of
Agriculture” (2004) supports the adoption of modern technologies in processing and export
preparation of agricultural products. Standards such as DSt 3302:2015 (for dried fruits) and DSt
3285:2014 (for jams and preserves), approved by the “UzDavStandart” agency, establish
requirements for moisture content, organoleptic properties, and storage conditions of processed
products.
This article examines various methods for processing stone fruits, including drying, canning,
jam production, juice production, and nutritional supplements. The study aims to analyze the
efficiency of these methods, their impact on nutritional properties, energy consumption, and

environmental sustainability, as well as their applicability in Uzbekistan’s agriculture. Based on
scientific literature, practical data, and Uzbekistan’s experiences, the advantages, limitations,
and prospects of these methods are evaluated.
Main Body
1. Characteristics of Stone Fruits and the Importance of Processing
Stone fruits—apricot, plum, and cherry—are distinguished by their unique nutritional and
organoleptic properties. Apricots are rich in vitamin C (10–12 mg per 100 g) and antioxidants,
plums are a source of dietary fiber and potassium, and cherries are valued for their anthocyanins
and vitamin A content. Processing extends the shelf life of these fruits to 12–18 months,
preserves their nutritional properties, and enhances competitiveness in export markets. In
Uzbekistan, apricot and plum processing is traditional, while cherry processing has gained
popularity in recent years, particularly in premium markets. The choice of processing method
affects product quality, nutritional properties, and economic efficiency. Improper processing
can lead to a 20–40% loss of vitamin C and .
2. Drying Methods.
Drying is the most common method for processing stone fruits, reducing
moisture content to 10–15% and extending shelf life.
2.1 Natural Drying (Sun Drying).
Natural drying involves drying apricots, plums, and cherries
in open air under sunlight and natural ventilation. Uzbekistan’s dry climate (3000 hours of
sunshine annually) makes this method viable. Its advantages include zero energy consumption
and environmental friendliness. In the Fergana Valley, over 20,000 tons of apricots are sun-
dried annually for local markets. However, the process takes 7–14 days and is weather-
dependent. Risks include dust, insects, and microbiological contamination, with a 20–30% loss
of vitamin C. The delicate structure of cherries makes quality maintenance challenging.
2.2 Mechanical Drying.
Mechanical drying is conducted in drying chambers at controlled
temperatures (50–70°C) and humidity levels, taking 2–4 days. It ensures consistent quality and
low contamination risk. Apricots and plums retain 80–85% of vitamin C, while cherries retain
up to 75% of anthocyanins. Enterprises like “AgroExport” in Uzbekistan process over 10,000
tons of products annually using mechanical drying (Uzbekistan Statistics Agency, 2024).
Energy consumption is high (500–700 kWh per ton), but hybrid solar-powered equipment can
reduce costs by 30–40%.
2.3 Modern Drying Methods
• Infrared Drying: Dries in 4–6 hours, retaining 85–90% of nutritional properties, ideal for
apricots and cherries (Zhang et al., 2022).
• Microwave Drying: Dries in 1–2 hours but may reduce antioxidants in cherries.
• Lyophilization (Freeze-Drying): Retains 95% of nutritional properties, suitable for premium
markets but costly and less common in Uzbekistan.
3. Canning.
Canning involves preserving stone fruits in syrup, packaged in glass jars or plastic
containers. Apricots and cherries are widely used for canning, while plums are less common.

The process includes pasteurization (80–100°C) or sterilization to ensure microbiological safety.
Advantages include preservation of natural taste and texture. However, high sugar content and a
15–25% loss of vitamin C are limitations. In Uzbekistan, canning is primarily used by small
enterprises for local markets, but standardization is needed for export.
4. Jam and Preserve Production
Jam and preserves are commonly made from apricots and
plums, with cherries used less frequently. The process involves cooking fruits with sugar.
Nutritional properties are partially lost (30–40%), but shelf life extends to 12–24 months.
Enterprises like “Samarkand Fruit” export apricot jam to Russia and Kazakhstan (Uzbekistan
Statistics Agency, 2024). Demand for eco-friendly packaging (glass jars) and sugar-free jams is
increasing.
5. Juice and Nectar Production.
Juice and nectar production from apricots and cherries is
widespread, with plum juices valued for their high dietary fiber content. The process involves
crushing, filtering, and pasteurizing the fruits. Pasteurization results in a 20–30% loss of
vitamin C, but 70–80% of antioxidants are retained (Smith et al., 2020). In Uzbekistan,
enterprises like “Fergana Juice” produce 5,000 tons of apricot juice annually.
6. Nutritional Supplements and Other Products.
Processing dried fruits into flour (e.g.,
apricot flour), granules, or nutritional supplements expands product diversity. Apricot and
cherry flour are used in bakery products and desserts, while plum granules are suitable for
nutritional bars. These products are in demand in premium markets.
7. Prospects for Stone Fruit Processing in Uzbekistan.
Stone fruit processing is a significant
contributor to Uzbekistan’s export market. In 2023, over 50,000 tons of dried apricots and
plums and 5,000 tons of cherry products were exported. Modern technologies (lyophilization,
infrared drying) and organic certification can increase export prices by 20–30%. Solar-powered
equipment reduces costs by 30–40%, while farmer training and eco-friendly packaging
(biodegradable materials) enhance market demand.
Conclusion
Various methods for processing stone fruits—drying, canning, jam production, juice production,
and nutritional supplements—are crucial for advancing Uzbekistan’s agriculture and export
potential. Natural drying is cost-effective but limited in quality consistency. Mechanical and
modern methods offer high quality but require significant investment. Canning, jam, and juice
production meet both local and international demand. Recommendations include adopting
hybrid technologies, solar energy, organic certification, and farmer training to enhance
processing efficiency and competitiveness.
