The consumption of beans has been associated with chronic disease prevention which may be attributed to the polyphenols present in the seed coat and endosperm. However, their bioaccessibility is likely to be limited by interactions with bean matrix components, including starch, protein and fibre. The aim of this project was to evaluate the effect of domestic processing and enzymatic digestion on the bioaccessibility of polyphenols from Borlotti beans (Phaseolus vulgaris) and to test their anti-inflammatory properties in a macrophage cell model. In vitro digestion of cooked beans released twenty times more polyphenols (40.4 ± 2.5 mg gallic acid equivalents (GAE)/g) than domestic processing (2.22 ± 0.1 mg GAE/g), with starch digestion contributing to the highest release (30.9 ± 0.75 mg GAE/g). Fluorescence microscopy visualization of isolated bean starch suggests that polyphenols are embedded within the granule structure. LC-MS analysis showed that cooked Borlotti bean contain flavonoids, flavones and hydroxycinnamic acids, and cooked bean extracts exerted moderate anti-inflammatory effects by decreasing mRNA levels of IL1β and iNOS by 25% and 40%, respectively. In conclusion, the bioaccessibility of bean polyphenols is strongly enhanced by starch digestion. These polyphenols may contribute to the health benefits associated with bean consumption.

Abstract We aimed to evaluate the physicochemical properties and starch gelatinization of an Iranian corn grain (single crass 702) processed using different thermal processing methods including 1) grinding (G, 2mm), 2) super-conditioned pelleting (SCP; moisture 20%, retention time 6 min and conditioning temperature 95°C), 3) extruding (EX; moisture 20%, temperature of melting zone 75°C and die zone 125°C, screw speed 75 rpm and time 150s) and 4) puffing (PUF; puffing temperature 200°C, hot air velocity 25 m/s, feed rate 100 g/m). The particle size of the samples was measured through sieves. Apparent density and chemical composition were measured based on AOAC methods. Starch gelatinization was determined in accordance with the enzymatic procedure. Data were analyzed by GLM procedure of SAS (P< 0.05) using a completely randomized design with 4 replications for every treatment. Apparent density in G and SCP corn were similar but greater than EX and PUF corns (0.85 and 0.77 via 0.29 and 0.06 (kg/L), respectively). The PUF corn showed the most geometric mean particle size (10.55 mm) and followed by EX (8.68 mm), SCP (3.55 mm) and G (1.60 mm). The DM, OM, CP, EE, NDF and NFC % were not significantly (P > 0.05) affected by different processing methods. Starch content in thermal processing methods of SCP, EX and PUF (73.27, 73.22 and 73.20 % of DM, respectively) was greater (P = 0.04) than the G corn (72.23 % of DM). The highest (P < 0.01) starch gelatinization was provided by the PUF (26.85 %), followed by the EX, SCP and G processes (22.95, 16.45 and 4.68 %, respectively). Obtained results imply that super-conditioned pelleting process as a new processing method despite of greater apparent density provided more starch gelatinization similar to extruded and puffed corn, thus it can increase the efficacy of starch utilization in corn grain.

Abstract The objective of this pooled analysis was to evaluate the effect of Syngenta Enogen Feed Corn (SYT-EFC) and corn processing methods with byproducts on finishing cattle performance and carcass characteristics. Treatment factors consisted of SYT-EFC or commercial corn (CON) processed as dry-rolled (DRC) or high-moisture corn (HMC). Byproduct comparisons were 0, 18, or 30% distillers grains inclusions or with 30% Sweet Bran to determine if SYT-EFC effect was impacted by byproducts. Seven trials (n = 2,340 steers; initial BW = 327 ± 20 kg) consisting of 252 pen means with 12 treatments were analyzed utilizing contrasts. Feeding SYT-EFC as DRC resulted in heavier final BW (P ≤ 0.03) and greater 12th rib fat (P < 0.01) compared to CON. There was a linear interaction between hybrid and distillers for G:F (P < 0.01). As distillers increased, G:F improved at a greater rate for CON compared to SYT-EFC. Feeding SYT-EFC as DRC with increasing distillers was not significantly different (P ≥ 0.68) from CON for G:F, but was 3% better than CON with 0% distillers. Feeding SYT-EFC as DRC with 18% distillers resulted in heavier final BW (P < 0.01) compared to 0 or 30% distillers. Feeding SYT-EFC as DRC with Sweet Bran resulted in heavier final BW (P ≤ 0.02) and greater ADG (P < 0.01) compared to CON. This increase in ADG with no difference in DMI, resulted in SYT-EFC diets having a 5.08% increase in feed efficiency (P < 0.01). The improvement for the corn is calculated to be 9.58% (5.08 / 0.53) when SYT-EFC was fed with Sweet Bran compared to a CON corn hybrid. No positive effects were observed when SYT-EFC was processed as HMC. These data suggest that SYT-EFC is better than CON hybrids when distillers inclusion is low or when fed with Sweet Bran.
