Soy-Based Lubricants
Published in Leslie R. Rudnick, Synthetics, Mineral Oils, and Bio-Based Lubricants, 2020
There are several examples of soy-based metal working fluids in use. A soy-based metal-removal fluid offers increased safety and performance as good as or better than standard petroleum-based fluids when machining steel and aluminum in cooling and lubricating the cutting surface as it removes small metal chips. This allows faster and more accurate machining to be done. The soy oil content provides biodegradability, nontoxicity, low volatile organic compounds emissions, a high flash point, and no offensive odor. Soy-based lubricants for the metalworking industry offer biodegradability, extended tool life, easy disposability, and soap-and-water cleanup. Soy oil offers excellent lubricity and high performance, and provides a safer alternative to petroleum. Using a soy-based product also helps to lower the costs associated with environmental compliance, including disposal costs [31].

Food hydrocolloids show an important role in adjusting the viscosity and elasticity (rheological properties) of liquid and solid food products. Soy proteins are used as functional ingredients in food manufacturing due to increased demand by virtue of their role in human nutrition and health (Utsumi et al., 1997). Polysaccharides are cast off in admixture to proteins mainly to improve the stability of dispersed systems (Dickinson, 2003). Gelling properties and other functional properties of proteins are being modified in the presence of hydrocolloid gums (Hua et al., 2003). The gelation behavior of protein-polysaccharide mixtures generally falls into three patterns, i.e., the formation of covalent bonds between two polymers; polyanion-polycation electrostatic interactions; and formation of composite gel due to the mutual exclusion of each component (Morris, 1990).
Sources of Endocrine Disrupters

Phytoestrogens have many structural similarities to 17β-estradiol and are more potent in vitro than many of the man-made chemicals tested to date.35 This has raised concern over exposure to phytoestrogens from dietary regimes, particularly those with a high proportion of soy products, typical of diets in Asia and the far East. On consuming products containing phytoestrogens, there are several possible pathways: ExcretionAbsorptionTransformation to other compounds

Soybean (Glycine max L. Merrill) seeds are popular legume seeds and are widely consumed in Asia countries. The soybean is a raw material for various products, such as tofu, soy sauce, soy oil and soymilk in the soy industry.[1] The soy by-products from soy processing are good sources of proteins, carbohydrates, lipids and minerals. Soy residues are also available as bioactive compounds, including phenolics, flavonoids and isoflavones.[2] The main flavonoid in soybean and soy residues is isoflavone and these compounds are related with the protection of oxidative stress in the human body, which is a cause of several diseases such as cancer, cardiovascular disease, obesity, and diabetes.[2] Many studies have demonstrated the positive aspects of isoflavones on health-promotion, such as the ability to reduce the risk of cardiovascular disease, cancer, and diabetes.[3,4]

NPs are produced from proteins/polysaccharides complex create a novel structure with new functional properties in food technology.[12] In this study, isolated soy protein (ISP) and basil seed gum (BSG) complexes have been used to fabricate NPs. Soy protein is one of the most available sources of plant proteins, which has noticeable functional properties, nutritional values, and even potential health effects. Lui and Tang (2013) reported ISP NPs could be effectively adsorbed at the interface of oil-water with no significant changes in particle morphology, which shows the potential of ISP NPs as Pickering stabilizers. BSG is an anionic hydrocolloid, which consists of glucose, galacturonic acid, glucomannan, mannose, arabinose, glucuronic acid, rhamnose, and galactose.[13] BSG exists in random coil conformation in the dilute regime, but it can change to ordered conformation under favored conditions such as the presence of binding agents, high enough concentration, change of temperatures, and pHs.[14] The carboxylate groups of BSG can be cross-linked by calcium ions to form NPs. Naji-Tabasi et al. (2018) developed BSG NPs for oral delivery of peptide (glutathione).
Human exposure to synthetic endocrine disrupting chemicals (S-EDCs) is generally negligible as compared to natural compounds with higher or comparable endocrine activity. How to evaluate the risk of the S-EDCs?

Data on estrogen activities have been taken from different experimental approaches, such as competitive binding to recombinant human estrogen receptor of MCF-7 cells, the proliferation of MCF-7 human breast cancer cells (E-SCREEN) or expression of a reporter gene in the yeast estrogen system (YES). The results of these assays showed that the relative in vitro potencies of o,p’-DDT, p,p’-DDT, PCBs, 4-nonylphenol, bisphenol A, and dieldrin are several orders of magnitude lower than that of 17β−estradiol. The phytoestrogen genistein present in soy-based food at high concentrations had a higher potency (estrogen receptor binding affinity and intrinsic efficacy at the estrogen receptor) as compared to the investigated S-EDCs. Thus, it may exhibit estrogenic activity that exceeds the activity of circulating 17β−estradiol in persons who consume soy-rich diets. Genistein’s serum concentrations vary over a wide range in individuals consuming diets with varying soy content, leading to a wide range of possible estrogenic activity for this N-EDC.
