They are composed of amino acids, which can be divided into two categories: animal proteins and plant proteins. Plant proteins have become increasingly popular in recent years due to their advantages over animal proteins, such as being more sustainable and environmentally friendly. This paper will focus on the application of plant proteins in food products. Definition and Advantages of Plant Proteins Plant proteins are defined as protein sources derived from plants such as cereals, legumes, nuts, seeds and vegetables. They can be further classified into two types: whole plant protein sources (e.g., soybeans) and isolated plant protein sources (e.g., pea protein isolate). Compared with animal proteins, plant proteins have several advantages including higher nutritional value (i.e., higher content of essential amino acids), better digestibility and lower allergenicity [1]. In addition, they are also more sustainable due to their lower environmental impact [2]. Application of Plant Proteins in Food Products Plant proteins have been widely used as ingredients in various food products including dairy products, breads, frozen foods, beverages, snacks and others [3]. Dairy products are one of the most popular applications for plant-based ingredients due to their high nutritional value. For example, soy milk is a popular alternative to cow’s milk because it is lactose-free and contains a good balance of essential amino acids [4]. In addition to dairy products, breads made with plant-based ingredients such as wheat gluten or oat bran also provide a healthier alternative for consumers who want to reduce their intake of saturated fat or cholesterol [5]. Furthermore, frozen foods made with vegetable-based ingredients such as peas or corn can provide consumers with more nutritious meal options than traditional frozen foods [6]. Beverages such as soymilk or almond milk are also becoming increasingly popular among health conscious consumers who want to reduce their calorie intake while still getting enough nutrients from their diet [7]. Snacks made with vegetable-based ingredients such as nuts or seeds can provide consumers with healthy alternatives that contain fewer calories than traditional snacks like chips or candy bars [8]. Finally, other food products like veggie burgers or tofu dishes can provide vegetarian consumers with a delicious source of protein without sacrificing taste or texture [9]. Challenges & Future Directions Despite the wide range of applications for plant-based ingredients in food products there still remain some challenges that need to be addressed before they can become widely adopted by manufacturers. One major challenge is the cost associated with using these ingredients which is often higher than using traditional animal-derived ingredients[10] . Additionally , there is still limited knowledge about how different types of processing methods affect the nutritional quality , safety , shelf life , flavor profile , texture profile etc .of these foods[11] . Finally , there remains an urgent need for further research into novel methods for producing high quality functional food product s containing these ingredient s[12] . In conclusion , although there remain some challenges associated with using plant - based ingredient s in food product s , this area holds great potential for future research and development due to its potential health benefits .
