Abstract

Breadfruit is rich in starch and pectin. The pectin can alter the digestion process of starch, however, the specific mechanism by which various soluble pectin impact starch digestion remains unclear. The effects of water-soluble pectin (WSP), chelating agent soluble pectin (CSP), and sodium carbonate soluble pectin (SSP) on the digestibility of breadfruit starch were characterized by means of RVA, FTIR, DSC, ITC, SEM and in vitro digestion. The results showed that the three types of pectin could inhibit starch digestion. The addition of CSP increased the resistant starch content from 8.18% to 18.07%, and the addition of SSP increased the slow-digested starch content from 22.55% to 35.24%. The three pectin have different ways in inhibiting starch digestion. They have different principles in inhibiting starch digestion. WSP binds with the dissolved amylose to form a membrane that covers the surface of the starch particles. However, CSP and SSP penetrate into the starch granule during the gelatinization process, blocking the pores on the starch particle surface, thus reducing the starch digestibility.

期刊介绍： Food Hydrocolloids publishes original and innovative research focused on the characterization, functional properties, and applications of hydrocolloid materials used in food products. These hydrocolloids, defined as polysaccharides and proteins of commercial importance, are added to control aspects such as texture, stability, rheology, and sensory properties. The research's primary emphasis should be on the hydrocolloids themselves, with thorough descriptions of their source, nature, and physicochemical characteristics. Manuscripts are expected to clearly outline specific aims and objectives, include a fundamental discussion of research findings at the molecular level, and address the significance of the results. Studies on hydrocolloids in complex formulations should concentrate on their overall properties and mechanisms of action, while simple formulation development studies may not be considered for publication. The main areas of interest are: -Chemical and physicochemical characterisation Thermal properties including glass transitions and conformational changes- Rheological properties including viscosity, viscoelastic properties and gelation behaviour- The influence on organoleptic properties- Interfacial properties including stabilisation of dispersions, emulsions and foams- Film forming properties with application to edible films and active packaging- Encapsulation and controlled release of active compounds- The influence on health including their role as dietary fibre- Manipulation of hydrocolloid structure and functionality through chemical, biochemical and physical processes- New hydrocolloids and hydrocolloid sources of commercial potential. The Journal also publishes Review articles that provide an overview of the latest developments in topics of specific interest to researchers in this field of activity.
