Abstract

"HIDRóLISE FOSFóRICA DE AMIDOS". Compreendendo o processo aplicável nas indústrias alimentícia ou médico-farmacêutica ou química para a hidrólise fosfórica de amidos ou féculas ou cultivares tuberosos ou cereais ricos em amiláceos, enquanto altemativa à hidrólise clorídrica convencional, o qual é executado usando como catalisador o ácido fosfórico diluído entre pH 5,0-1,0 ou mais concentrado, mediante simples aquecimento ou aquecimento sob pressão, ou termopressurização, durante tempos variáveis de residência no reator, a partir de soluções ou suspensões diluídas ou concentradas destes materiais amiláceos, com o objetivo de produzir soluções ou xaropes enriquecidos em glucose e/ou maltose e/ou maltossacarídios com grau de polimerização acima de 3 e/ou maltodextrinas (1-A e 1-B; 2-A a 2-H), mantendo ou não o catalisador como tal ou neutralizado em ditos produtos, os quais, comparativamente à hidrólise clorídrica, exploradas as condições cinéticas de pH, temperatura e tempo de reação, vêm acompanhados de menor teor de subprodutos coloridos (4-A e 4-B) ou incolores, insípidos ou não, como hidroximetilfurfural (3-A a 3-C) e/ou subprodutos, similares ou não, oriundos da desidratação ou condensação de açúcares liberados do amido ou de outros carboidratos contaminantes, e mesmo de proteínas ou lipídios residuais, caso este quando féculas menos purificadas são hidrolisadas."PHOSPHORIC HYDROLYSIS OF STARCHES". Understanding the process applicable in the food or medical-pharmaceutical or chemical industries for the phosphoric hydrolysis of starches or tuberous cultivars or cereals rich in starch, as an alternative to conventional hydrochloric hydrolysis, which is performed using the phosphoric acid diluted between pH as a catalyst 5.0-1.0 or more concentrate, through simple heating or heating under pressure, or thermopressurization, during variable residence times in the reactor, from diluted or concentrated solutions or suspensions of these starchy materials, with the objective of producing solutions or syrups enriched in glucose and / or maltose and / or maltosaccharides with a degree of polymerization above 3 and / or maltodextrins (1-A and 1-B; 2-A to 2-H), maintaining or not the catalyst as such or neutralized in said products, which, compared to hydrochloric hydrolysis, exploited the kinetic conditions of pH, temperature and reaction time They are accompanied by a lower content of colored by-products (4-A and 4-B) or colorless, tasteless or not, such as hydroxymethylfurfural (3-A to 3-C) and / or by-products, similar or not, arising from dehydration or condensation of sugars released from starch or other contaminating carbohydrates, and even proteins or residual lipids, if this is when less purified starches are hydrolyzed.
