Product Introduction

Freeze-dried lemon powder is a versatile ingredient, derived from fresh lemons, that offers a convenient way to incorporate the flavor and nutritional benefits of lemons into various applications, without the need for fresh fruit. The powder retains the characteristic tangy flavor and aroma of lemons, making it a valuable addition to both culinary and health-related products.

Production Process

The production of freeze-dried lemon powder involves several key steps aimed at preserving the quality and nutritional content of the original fruit. First, fresh lemons are selected, washed, and processed into juice or slices. Next, the lemon material is rapidly frozen, which helps to maintain its cellular structure. The frozen lemon is then placed in a freeze-drying chamber, where a vacuum is applied to remove the water content, through a process called sublimation. After drying, the resulting product is milled into a fine powder, sieved, and packaged to prevent moisture absorption.

Nutritional Composition Table

The typical nutritional composition of freeze-dried lemon powder per 100g is as follows:

NutrientAmount (approximate)

Note: These values can vary based on the specific lemon variety, growing conditions, and processing techniques.

Product Benefits and Functions

Freeze-dried lemon powder offers various health and functional benefits. Its high Vitamin C content supports immune function and acts as an antioxidant, protecting the body against free radicals [1]. The citric acid content contributes to its tangy flavor and may aid in digestion [2]. Additionally, lemon powder can be used as a natural flavoring agent in foods and beverages, providing a zesty taste without the need for artificial additives.

Product Application Scenarios

Botanical Source

Lemons (Citrus limon) are believed to have originated in Northeast India, and are now cultivated in many subtropical and tropical regions around the world [3]. The fruit is known for its acidic juice, and its peel is rich in essential oils, contributing to its distinctive aroma and flavor.

Packaging and Storage

To maintain the quality and prevent degradation, freeze-dried lemon powder should be stored in airtight containers, away from direct sunlight, and in a cool, dry environment. Proper packaging helps to prevent moisture absorption, which can lead to clumping and loss of flavor [4]. Under optimal conditions, the shelf life of freeze-dried lemon powder can extend up to 12-18 months.
