Soybeans are normally processed to obtain protein isolates or other end-products such as soymilk and tofu. During this process, a fibre-rich residue called okara is removed. Large quantities of byproducts generated during plant food processing create an economic and environmental problem due to their high volume and elimination costs. Today, they are considered a promising source of functional compounds. After isolation of the main constituent, there are abundant remains that are an inexpensive material that has been undervalued until now, as it was only used as fuel or fertilizer. During the extraction of oil from soybeans, a substantial number of byproducts are produced. Specifically, these byproducts include soybean gums and soapstocks. These byproducts become potentially valuable to the manufacturer when they are efficiently recovered and processed.

Soybean is a legume and an abundant source of proteins called soy protein isolates that have gained popularity due to their high nutritional value. The important component for soy protein isolate is glycinin and β conglycinin. Soy protein isolates based nanoparticles are commonly synthesized by desolvation technique by adding crosslinkers such as tripolyphosphate (TPP). When subjected to heat denaturation, these protein aggregates, and links to the crosslinkers forming nanoparticles. Soy protein nanoparticles were developed by Verma et al. (2018) for the targeted delivery of bioactive components like curcumin. Stabilizers for oil in water emulsion were developed with soy protein nanoparticles by Singh et al. (2017). Two types of soy protein nanoparticles were prepared with heat treatment and without heat treatment and from the results, it was indicated that the heat-denatured protein of soy isolate showed better results. A gel-like network was formed by the protein which could encapsulate oil droplets and therefore these protein emulsions could stabilize Pickering.

Soybean, a species of legume native to East Asia, is an annual plant that has been used as a food source for centuries and has even been used for medicinal purposes in China. The dominance of soybean as a global oilseed resource can be attributed to its advantageous agronomic characteristics, high oil content for food and fuel purposes, and highly nutritive protein content. The top five producers of soybean are the US, Brazil, Argentina, China, and India with respective annual production rates of 70.7, 58.2, 45.5, 15.6, and 9.4 million tons in 2007 (FAO, 2008). Soybean production can be maximized when grown in moist fertile loams at an optimum temperature of around 25°C (Martin et al., 2006). A day length ranging from 12–14 h is considered optimum for blooming, and a pH range of 6–6.5 is desirable for most soybean cultivars (El Bassam, 1998).

Soybean is an important source of vegetable oil and protein for human consumption and an important raw material for the pharmaceutical, ink, and cosmetic industries (Nishinari et al. 2014). Globally, China is the leading producer and consumer of soybean; however, because China’s total soybean yields are insufficient for satisfying the demands of its large population, 82% of the soybean consumed in China is imported (Bicudo da Silva et al. 2017). Moreover, spring soybean production in China is concentrated in three northeastern provinces, whereas summer soybean production primarily occurs in Anhui, Jiangsu, and Henan provinces (Jin et al. 2019). Soybean is a Cd-sensitive crop, and its growth is severely inhibited after exposure to Cd concentrations exceeding permitted levels in soil (Zhao et al. 2014; Zhan et al. 2019). The existing data show that elevated toxins in soybeans extensively threaten Asian residents and over one billion vegetarians worldwide, for example, Cd concentration of grain of soybean in some Chinese calcareous soils reached to 0.32 mg·kg−1 (Zhang et al. 2021).

Soybean is one of the richest and cheapest sources of dietary proteins (about 40%) with a high nutritional value and is a main component in the diets of people and animals in many parts of the world. The main proteins of soybean are glycinin and conglycinin. Functional properties of soy proteins such as emulsifying activity, water holding capacity along with its role as a carrier in the encapsulation of various bioactive compounds are the most important applications of soy protein.[58] Numerous studies have investigated application of soy protein isolate (SPI) as a carrier in the encapsulation process of bioactive peptides and hydrolyzed proteins. Favaro-Trindade et al.[78] studied the effect of different processes and ratios of carriers on bitterness and physical properties of hydrolyzed casein. According to their results, SPI had a significant impact on spray-dried casein hydrolysate. Mendanha et al.[69] did a general research on microencapsulation of casein hydrolysates with SPI and pectin as carriers using the complex coacervation. They analyzed some remarkable properties like hygroscopicity, solubility, hydrophobicity, surface tension, microencapsulation efficiency and bitterness of the samples. Their results showed that, using of mentioned carriers resulted in a decrease in the hygroscopicity index.

The potential of AMF to promote plant growth and reduce heavy metal stress is well known, but not fully utilized, especially in agricultural crops such as soybean. Soybean (Glycine max L.) is an oilseed legume grown widely in most parts of the world due to its high-quality oil and protein content for livestock and human consumption, as well as industrial purposes (Adeyemi et al. 2020). To our knowledge, there is limited information about the growth and physiological responses of soybean with Rhizophagus intraradices under heavy metal stress conditions. Thus, the present study was conducted to investigate the effect of AMF inoculation on growth, morphological, nutrient uptake and stress tolerance index of soybean plants under toxicity of Cu, Zn and Pb.
