| Summary: | Abstract This comprehensive review delves into the realm of fruit seed proteins, examining their extraction methods, physicochemical properties, and functional characteristics. These proteins exhibit tremendous potential for diverse applications within the food industry. By gaining insights into efficient extraction techniques and understanding the physicochemical and functional properties of fruit seed proteins, researchers and industry professionals can harness their advantages to develop innovative food products. Various extraction methods, such as acid alkali, microwave‐assisted, ultrasound‐assisted, reverse micelle extraction, and the Box–Behnken experimental design, have been used for extracting proteins from a range of fruit seeds, including jackfruit, kiwi, watermelon, date palm, and grape seeds. The selection of these methods was based on their efficiency, protein yield, and compatibility with fruit seed proteins, with any associated limitations duly acknowledged by the researchers. The review also explores physicochemical characterization techniques such as Fourier transform infrared, thermogravimetric analysis, differential scanning calorimetry, and scanning electron microscopy, used specifically for jackfruit seed protein, while delving into essential functional properties including solubility, water‐binding capacity, oil‐binding capacity, emulsifying capacity, foaming capacity, and bulk density. These properties play a crucial role in determining the suitability of fruit seed proteins for various food applications, significantly impacting factors like texture, crispiness, and color. Waste fruit seeds, often overlooked, can serve as a valuable source of proteins, possessing multifunctional properties encompassing nutrition, structure, enzymes, emulsification, foaming, gelation, and thickening. However, compared to other protein sources, fruit seed proteins have received limited scientific attention, rendering this review a distinctive and valuable contribution to the existing literature by offering comprehensive insights into extraction methods and properties.
