Evaluation of retrograded starch as excipient for controlled release matrix tablets
(2017-08-01)
High amylose starch (HAS) was retrograded by two different methods. The physicochemical properties of the retrograded materials were evaluated and structural changes were highlighted. Micromeritics properties were demonstrated ...
Development and characterization of cross-linked gellan gum and retrograded starch blend hydrogels for drug delivery applications
(2017-01-01)
The retrogradation of high amylose starch (5% or 10%), by isothermal cycles at 4 °C (method 1) or by alternating thermal cycles (method 2) was efficient and promoted important structural modifications. Hydrogels of gellan ...
Cellulose nanofibers improve the performance of retrograded starch/pectin microparticles for colon-specific delivery of 5-ASA
(2021-09-01)
Cellulose nanofibers (CNF) were employed as the nanoreinforcement of a retrograded starch/pectin (RS/P) excipient to optimize its colon-specific properties. Although starch retrogra-dation ranged from 32 to 73%, CNF addition ...
Sponge cake microstructure, starch retrogradation and quality changes during frozen storage
(Wiley Blackwell Publishing, Inc, 2016-08)
The effect of frozen storage (6 months) on the microstructure (microscopy, flatbed scanning and image analysis), quality (texture, moisture and specific volume) and starch retrogradation of the cake crumb were evaluated. ...
Retrograded starch/pectin coated gellan gum-microparticles for oral administration of insulin: A technological platform for protection against enzymatic degradation and improvement of intestinal permeability
(2018-02-01)
Gellan gum microparticles coated with colon-specific films based on retrograded starch and pectin was developed for enhancing the oral release of insulin (INS). The system developed promoted an impressive protection of INS ...
Effect of amylolysis on the formation, the molecular, crystalline and thermal characteristics and the digestibility of retrograded starches
(2020-11-15)
This study evaluated the effect of amylases on the formation, and characteristics of retrograded starches using sweet potato (SPS), cassava (CAS) and high amylose maize (HAS) starches. The starches were gelatinized, ...
Crystallinity, thermal and pasting properties of starches from different potato cultivars grown in Brazil
(2016-01-01)
Starches from different potato cultivars were characterized as amylose and phosphorus content, crystallinity, thermal and paste properties. Statistical analysis of amylose content showed difference between starches samples ...
Influence of green tea and basil extracts on cassava starch based films as assessed by thermal degradation, crystalline structure, and mechanical properties
(Wiley VCH Verlag, 2019-12-17)
Natural extracts are investigated as plasticizers of starch?glycerol biobased films for food coating applications. For this purpose, films with cassava starch, glycerol, and distilled water with and without green tea or ...
In vitro Digestibility and Glycemic Response of Potato Starch is Related to Granule Size and Degree of Gelatinization
(WILEY, 2009)
Starch granule microstructure affects the digestion of starch and its nutritional impact; however, the exact relationship between both factors is not clear. This study reports quantitative relationships between granule ...
