Abstract: A process for the treatment of wastewater, commonly known as nejayote, from the nixtamal, masa and tortilla industry, having an improved method for removing the insoluble fraction and a filtration system for separating and concentrating the fractions forming the nejayote is described. The method includes the steps of: (a) neutralizing the nejayote; (b) enzymatically hydrolyzing the starch granules; and (c) flocculating and separating the insoluble fraction. The system includes the steps of (a) microfiltration; (b) ultrafiltration for concentrating long-chain carbohydrates; (c) ultra/nano filtration for concentrating medium-size compounds; and (d) nanofiltration/reverse osmosis for concentrating small molecules and obtaining water of sufficient quality that it can be re-used or safely discharged into the environment.

Abstract: A novel integral process for the treatment of wastewater, commonly known as nejayote, from the nixtamal, masa and tortilla industry, having an improved method for removing the insoluble fraction and a filtration system for separating and concentrating the fractions forming the nejayote.

Abstract: This invention comprises applying phytoceutical compositions to pets, which given their sedentary life and nutrition, are susceptible to a higher prevalence of cancer and degenerative diseases. The compounds contained in said compositions frequently have anti-oxidizing properties acting to inhibit harmful reactions of free radicals; free radicals are often a cause of cancer. Said compositions comprise extracts or concentrates obtained from the enzymatic or alkaline hydrolysis of several plant sources, containing effective concentrations of two or more phenolic compounds, such as ferulic acid, coumaric acid, caffeic acid, protocathecoic acid, and vanillic acid.

Abstract: A natural method to promote or enhance food efficiency and muscle/fat ratio in animals is described, particularly for pigs, through the administration of an effective amount of pure ferulic acid, substantially pure ferulic acid or ferulic acid formulations. Prepared food and formulations for animals are also described, which can increase muscular development in pigs, decreasing fat deposits or promoting or increasing animal growth or enhancing food efficiency in an animal. Effective amounts of pure ferulic acid or substantially pure ferulic acid use in said food preparations and formulations are described.
