“…9,10 Spherical particles have excellent geometry and microstructure, which greatly enhances product stability during production, storage, and use. 11−14 Particularly in the food sector where the shape of the particles affects the taste, texture, and appearance of food products, 15 spherical particles can effectively improve the crystal quality, as well as the food properties, using sphericity as an important factor in the evaluation of spherical particles. In addition, spherical particles have been widely used in a variety of food additives and fertilizers, such as sugars, amino acids, and inorganic salts, and play an important role in anticaking and explosives crystal stability.…”

As one of the eight essential amino acids in the human body, l-isoleucine plays an important role in human life metabolism and can be applied as a nutritional supplement and food additive in the food field. However, the crystallization of l-isoleucine is generally flaky with poor powder properties, such as bulk density and flowability, which is not conducive to a wide range of industrial applications. In this study, we successfully prepared large spherical particle crystals via two different ways of crystallization. l-Isoleucine undergoes the evolution from initial round flakes to three-dimensional petal-like structures and finally to spherical particles by evaporation crystallization in the presence of hydroxypropylmethylcellulose (HPMC). l-Isoleucine also aggregates into spherical particles in the acid–base reaction crystallization process by adding a small amount of suitable and volatile bridging liquids, such as cyclohexane and ethyl acetate. In conclusion, both approaches improved the crystal properties of l-isoleucine and produced spherical particles with a larger particle size, higher bulk density, and higher compression resistance, thereby providing new insight into the preparation of high-quality l-isoleucine.
