  • Plant proteins are the main components of many foods and also the important raw materials for industrial applications. Natural proteins do not always meet the requirements of industrial applications due to their functional limitations. Complexation with carbohydrates and lipids is one important way utilized to improve the properties of proteins. This chapter discusses the interaction forces between proteins and carbohydrates (starch and nonstarch polysaccharides) or lipids during the complex formation. Next
  • factors influencing the formation and characteristics of these protein-based complexes are discussed. After these

Atmospheric cold plasma had slight effect on the nutrition and sensory. Atmospheric cold plasma contributed to improve the stability of coconut milk. Commercial sterilization plays an important role in extending the shelf-life of coconut milk. However
  • thermal sterilization affects the quality of coconut milk. This study was initiated to evaluate the effects of atmospheric cold plasma (ACP) treatment on some important quality parameters of coconut milk.
