不同竹笋粉添加量的面团特性及面包品质的变化

竹笋含有丰富的营养成分。为了探讨竹笋粉对面团和面包品质影响,该研究把竹笋粉以不同添加量（0%、3%、5%、7%,m/m）加入到小麦粉中制作成面包,对面团面筋蛋白、面包色泽、感官、质构特性和贮藏性进行测定。结果表明：随着竹笋粉添加量的增加,面团面筋蛋白含量降低,面包硬度和咀嚼性均提高。低剂量竹笋粉的添加（3%~5%）对面团的pH值和面筋含量影响不显著（P>0.05）,但添加量为7%时湿面筋含量相对下降了9.87%,影响显著。竹笋粉添加与面包的比容和失水率呈负相关,空白组、添加量3%、5%、7%（m/m）的失水率分别为2.45%、2.09%、2.17%、1.77%,其硬度、胶着性、弹性以及咀嚼性变化显著（P<0.05）,对内聚性、回复性影响不显著（P>0.05）。添加竹笋粉（3%~5%）可以提升面包的色泽,使面包具清香风味,但7%的添加量使面包的色泽过深,气味较浓。说明低剂量（3%~5%）的竹笋粉添加制备面包,可提升面包咀嚼感,亮色、丰富其营养成分,还起到延缓面包老化作用。

Isolation and characterization of collagen from the cartilages of brownbanded bamboo shark (Chiloscyllium punctatum) and blacktip shark (Carcharhinus limbatus)

Acid soluble collagen (ASC) and pepsin soluble collagen (PSC) from the cartilages of brownbanded bamboo shark (BBS; Chiloscyllium punctatum) and blacktip shark (BTS; Carcharhinus limbatus) were isolated and characterized. ASC and PSC extracted from BBS cartilage showed the yields of 1.27 and 9.59 g/100 g (Based on dry weight), respectively, while yields of ASC and PSC from BTS cartilage were 1.04 and 10.30 g/100 g (based on dry weight), respectively. All collagens had protein as a major constituent with the trace amount of ash and fat. They contained glycine as the major amino acid with high contents of alanine, proline and hydroxyproline. Based on sodium dodecyl sulfate-polyacrylamide gel electrophoretic patterns and subunit compositions, all collagens more likely comprised 2 types of collagen, type I and II, and contained α- and β-chains as the major components. Peptide maps of those collagens from both species digested by V8-protease and lysyl endopeptidase were different and were completely different from those of type I collagen from calf skin. Thermal transition temperature of ASC from those collagens (36.28-36.73 °C) was slightly higher than their corresponding PSC (34.56-35.98 °C). From zeta potential analysis, isoelectric points (pI) of collagen from the cartilages of BBS and BTS were estimated to be from 6.53 to 7.03 and from 6.96 to 7.26, respectively. Fourier transform infrared (FTIR) spectra of both ASC and PSC were quite similar, suggesting that pepsin hydrolysis did not affect the secondary structure of collagen, especially triple-helical structure.
