Introduction

Pine pollen has long been recognized as a valuable dietary supplement for both humans and animals, known for its rich nutrient profile and bioactive compounds. This study, published in "Biomolecules," explores the diverse applications of pine pollen as a functional food and feed ingredient. It provides an in-depth review of recent advancements and future perspectives in utilizing pine pollen, highlighting its nutritional benefits, functional properties, and potential health impacts.

Objective

To explore the potential of pine pollen as a functional food and feed ingredient, evaluating its nutritional composition, functional properties, and health benefits.

Methodology

Nutritional Composition and Benefits

• The study details the high content of carbohydrates, proteins, lipids, vitamins (particularly B vitamins), carotenoids, minerals, and polyphenols in pine pollen.
• Emphasis is placed on the nutrient bioavailability challenges posed by pine pollen's hard outer shell and the processing techniques used to enhance nutrient accessibility.

Functional Properties and Health Benefits

• The study examines the significant biological activities of pine pollen's natural metabolites, including antioxidant, antibacterial, anti-carcinogenic, hepatoprotective, and cardioprotective effects.
• Potential therapeutic treatments for non-allergic diseases, such as benign prostatic hyperplasia and chronic prostatitis, are also discussed.

Application in Functional Foods

• Pine pollen is incorporated into various food products, including granules, capsules, tablets, pellets, and powders, aiming to improve nutritional, functional, and sensory properties.
• Studies demonstrate enhanced antioxidant capacity, improved textural properties, and increased nutritional value in pine pollen-enriched products like yogurt, bread, and meat.

Anti-Nutritional Compounds and Safety Concerns

• The presence of anti-nutritional compounds, such as allergens, pyrrolizidine alkaloids, and mycotoxins, is addressed.
• Proper handling, processing, and quality control measures are emphasized to ensure safety and efficacy.

Recent Advances in Pine Pollen-Based Products

• The study highlights innovative pollen-based products developed through fermentation, encapsulation, and other processing techniques.
• Fermentation is noted for enhancing the bioavailability of pollen's bioactive compounds and improving sensory characteristics.
