Starch–methylcellulose–whey protein film properties

Four % (wt/wt) aqueous solutions were prepared at corn starch:methylcellulose:whey protein isolate (CS:MC:WPI) ratios of 2:2:2, 1:2:3, 2:1:3, 2:2:0, 1:2:0 and 2:1:0. Glycerol (gly) was used as a plasticiser at CS–MC–WPI:gly ratios of 2:1, 2.5:1 and 3:1. CS–MC–WPI blend films were stronger than CS–WPI films and had lower oxygen permeability (OP) than MC–WPI films. The highest tensile strength (TS) of blend films was 8.01 ± 3.41 MPa, at CS:MC:WPI ratio of 2:2:0 and CS–MC–WPI:gly ratio of 3:1. Lowest OP value was 45.05 ± 7.24 cm³ μm m^?2 per day kPa^?1, at CS:MC:WPI ratio of 2:2:2 and CS–MC–WPI:gly ratio of 3:1. OP values were predictable based on relative amounts of components. However, TS and elastic modulus properties of the CS–MC–WPI blend films did not reflect the relative amounts of the components. All of CS–MC–WPI films were translucent indicating some degree of immiscibility among the CS, MC and WPI. These results indicate the influence of complex molecular interactions among the components.     

大豆分离蛋白-葡聚糖糖基化产物作为乳化剂和活性物质载体的性能分析

研究大豆分离蛋白(soy protein isolate,SPI)-葡聚糖共价接枝物的制备及其乳化性质和作为姜黄素载体的性能。在95℃的"大分子拥挤"体系条件下,2种大分子通过美拉德反应进行共价接枝。根据糖基化产物在SPI等电点附近(p H 4.5)和中性(p H 6.5)条件下的溶解性将其分成2个组分,分别为MC45和MC65,并对其性能表征分析。十二烷基硫酸钠-聚丙烯酰胺凝胶电泳和分子质量测定分析显示,反应后生成大分子质量的接枝物。MC45制备的乳液在酸性环境中的粒度低于MC65,其平均粒径约为10μm,并且受离子浓度和温度的影响较小。与天然蛋白、SPI-葡聚糖混合物及MC45相比,荷载量、1,1-二苯基-2-三硝基苯肼(1,1-diphenyl-2-picrylhydrazyl,DPPH)自由基清除率分析表明MC65组分具有更好的姜黄素运载性能,MC65组分制备的姜黄素纳米颗粒荷载量为30.21μg/mg,DPPH自由基清除率为18.33%,其粒径最大。

Efficacy of colostrum replacer versus maternal colostrum on immunological status,health, and growth of preweaned dairy calves

Commercially available colostrum replacers (CR) are commonly used when maternal colostrum (MC) is unavailable, for managerial convenience, to ensure quality consistency at first feeding, or in disease control and eradication programs. The objective of this study was to determine the efficacy of feeding First Day Formula (Accelerated Genetics, Baraboo, WI) CR versus pooled MC on immunological status, growth, and health of preweaned dairy calves. A total of 1,220 Jersey and Jersey × Holstein calves born on a California Central Valley dairy farm were assigned after birth to receive either CR or MC following a systematic allocation procedure. Calves assigned to MC were tube fed 2.8 L of MC, and calves assigned to CR were tube fed a total of 500 g of CR (150 g of immunoglobulin G; IgG) mixed into 1.9 L of water at 1 h ± 5 min after the calf was born. A subset of calves was selected for passive transfer (n = 592) and growth (n = 268) analyses. Although both coliform count and total bacteria count were low for MC and CR fed to calves during the study, the predicted probability of calves receiving contaminated liquid feed (coliform count >10,000 cfu/mL) at first feeding was reduced for calves fed CR (1.5%) compared with calves fed MC (6.1%). The mean blood concentration of IgG was lower for calves fed CR than for calves fed MC (19.6 vs. 23.4 mg/mL). However, the apparent efficiency of absorption of IgG did not differ between treatments (34.4 and 35.9% for CR and MC, respectively). Total proteins were lower in calves fed CR compared with MC at 24 h (5.16 vs. 5.84 g/dL, respectively). Calves fed CR were 1.5 kg lighter at weaning and gained 0.03 kg less per day (0.30 vs. 0.33 kg/d, respectively) than calves fed MC before weaning. Height at weaning did not differ between the 2 treatment groups. Calves fed CR tended to have a higher predicted probability of not being treated for diarrhea than calves fed MC (0.142 vs. 0.110, respectively). However, when the disease was present, CR had a higher number of treatment days compared with MC (11.6 vs. 10.8 d, respectively). The hazard ratio of dying did not differ between MC and CR; however, CR calves had a numerically higher risk (hazard ratio = 1.347) of dying compared with calves that received MC. In conclusion, IgG absorption and serum concentration of calves were adequate when calves were fed either CR or MC. The CR-fed calves had a lower probability of receiving contaminated liquid feed and performed similar in terms of health compared with calves receiving high-quality MC, although they were slightly lighter at weaning. Therefore, the CR evaluated in this study is a valid alternative to high-quality (>50 mg of IgG/mL) MC.     

Effect of High Moisture Maize Storage on Tortilla Quality

We evaluate the effect of high moisture content (MC) stored maize grain on tortilla quality and on the growth of toxigenic fungi. Maize with a MC of 18% was stored for 10, 15, and 20 d at 28 °C. The control seed was stored 20 d with a MC of 10.7% at 4 °C. The high MC grain and the control were processed using the traditional nixtamalization process. Storage conditions had a significant effect on tortilla quality parameters such as pH, color, tensile strength, cut force, viscosity peak, starch retrogradation (setback), and aflatoxin contamination. Tortillas produced with high MC grain presented a lower quality than those produced with low MC grain.
