The effects of gamma irradiation, stearic acid alone and in combination on functional, structural and molecular characteristics of high amylose maize starch (Hylon VII) were studied. Stearic acid (0, 1.5 & 5 %) was added to Hylon VII starch, and then irradiated at 0, 30 and 60 kGy. Gamma irradiation significantly (P ≤ 0.05) increased solubility, water absorption capacity and oil absorption capa...

BACKGROUND Resistant starch sources, which are only partially digested in the small intestine, can be used to increase colonic availability of short-chain fatty acids. OBJECTIVE To study the characteristics of the fermentation of resistant starch, the digestion of resistant starch in the small intestine has to be quantified. We compared the metabolic fates of highly digestible cornstarch (DCS...

Cereal Chem. 78(4):442–446 In this study, 3% aqueous high-amylose maize starch (Hylon VII) dispersions were heated to temperatures of 140–165°C. The onset and rate of gel formation was observed using a small-strain oscillation rheometer as a function of temperature from 90 to 25°C. The gel formation clearly began earlier in high-amylose starch paste preheated at lower temperatures, but the rate...

BACKGROUND We investigated in rats the effects of feeding different forms of high amylose maize starches (HAMS) rich in resistant starch (RS) to understand what the implications of RS heterogeneity might be for colonic biology, including innate cellular responses to DNA-damage. METHODS A range of maize starches were compared: digestible cornstarch (Control), HYLON® VII, Hi-maize® 1043, Hi-mai...

This study investigated the in vitro digestibility, glycaemic index (GI) and bile acid–binding capacity (BABC) of some potential resistant starch source food products (PRSF). Commercially available (RS) samples, Hylon VII (RS2), Novelose 330 (RS3) Fibersym (RS4) were also included study. The RS content PRSF used this was range 25–77%. Standardised static digestion processes applied, total GI BA...

Microencapsulation with hydrocolloids as a modern technique has been used to prolong the survival of probiotics during exposure to harsh conditions. In this study, alginate-Hylon starch microcapsules with genipin cross-linked chitosan and poly-L-lysine coatings were developed to encapsulate four strains of probiotic bacteria, including Lactobacillus casei (ATCC 39392), Bifidobacterium bifidum (...

BACKGROUND Short-chain fatty acids (SCFAs) have a role in maintaining bowel health and can assist in the prevention and treatment of colonic disease. The ability of acylated starches to deliver SCFAs to the large bowel has been shown in animal studies but has not been established in humans. OBJECTIVE The aim was to determine whether cooked, highly acylated starches were resistant to small int...

In paediatric practice proper digestion of carbohydrates is of major importance for adequate growth and development and for prevention of intestinal complaints. Several carbohydrates can be considered in this respect: (a) lactose: the main carbohydrate in the nutrition of early life and also in later life for many white people; (b) starch: the main energy supplier in our food; (c) fructose: a c...

Potato starch offers several unique properties essential for nutrition, and numerous non-nutritional applications. First of all, it is the sole native starch of anionic character. For that reason, potato starch combines, for instance, with proteins forming various complexes considered as potential biodegradable plastics. Potato starch is, practically, the sole starch variety containing a consid...
