Heat-moisture and acid treatments can increase levels of resistant starch in arrowroot starch without adversely affecting its prebiotic activity in human colon microbiota.

Carbohydrates are an important macronutrient whose processing and digestive fate can have numerous beneficial or adverse effects on consumer health. This study investigated the impact of heat-moisture treatments (HMT) and citric acid treatments (CAT) on arrowroot starch (ARS) with a focus on its physicochemical properties, digestibility, and influence on gut microbiota. The results revealed that HMT and CAT did not alter the colloidal characteristics of ARS but significantly affected the balance between amorphous and crystalline regions.

Carrageenan impact on digestive proteolysis of meat proteins in meatballs or soluble hydrolyzed collagen.

In a health-conscious age, vivid discussion has been made on the healthfulness of processed foods and food additives. This study focuses on carrageenan (CGN), an approved but debated family of sulphated galactans from algae used as gelling, thickening and stabilizing agents but with indications of possible adverse effects, including as an inhibitor of digestive proteolysis. To challenge this inhibitory hypothesis, food-grade kappa-, iota and lambda-CGN preparations were used to produce beef meatballs whose proteolysis was studied using an in vitro digestion model coupled to various proteomic analyses.

Static digestion model adapted to the general older adult population: an INFOGEST international consensus.

Understanding the mechanisms of food digestion is of paramount importance to determine the effect foods have on human health. Significant knowledge on the fate of food during digestion has been generated in healthy adults due to the development of physiologically-relevant digestion models. However, it appears that the performance of the oro-gastrointestinal tract is affected by ageing and that a model simulating the digestive conditions found in a younger adult (<65 years) is not relevant for an older adult (>65 years).

Development and validation of a computerized web-based quantitative food frequency questionnaire.

Background & Aims: Epidemiological research is progressing towards digital data collection. This study aimed to evaluate the validity and reproducibility of our new computerized, and easy-to-use Food Frequency Questionnaire (FFQ).

Methods: Participants' dietary intake was assessed using 24-h Dietary Recalls (DRs) and our FFQ, consisting of 133 food items and beverages.

Inclusion of phenolic bioactives in high amylose corn starch for gastro-intestinal delivery.

Starch is a staple food component with intricate architectures, some of which can be utilized as polysaccharidic delivery vehicles for bioactive compounds. This work describes the use of high amylose corn starch (HACS) to fabricate V-amylose inclusion complexes entrapping capsaicin or curcumin. In line with past studies, X-ray diffraction, differential scanning calorimetry, static laser scattering and scanning electron microscopy help affirm the formation of V6III-type complexes.
