VB6.0在饼干炉温度的巡检运用

在自动控制和巡回检测系统中，需要进行数据通信，VB6．0已成为Windows98系统开发的主要语言，以其高效、简单易用等特点，解决数据通讯等问题，以下开放的这套系统有16个采集点，反映了饼干炉整体温度的变化范围，趋势等数据，发生数据传输冲突的可能性很大，这就要求，数据发送必须有先后次序的约定，本文提供了利用VB6．0编程工具来解决这个问题。     

改性菠萝皮渣膳食纤维添加对饼干品质的影响

为研究改性菠萝皮渣膳食纤维对饼干品质的影响,以改性菠萝皮渣膳食纤维为原料,添加到饼干中,测定饼干面团流变特性、饼干的理化性质以及感官特性。结果表明:随着改性菠萝皮渣膳食纤维添加量的增加,面团的弹性和黏性逐渐增加,呈现出弹性流体特性;饼干硬度、脆性和咀嚼性增加,弹性和回复性减小;饼干的明度和亮度降低,黄色调下降,红色调上升,颜色相对偏暗。当改性菠萝皮渣膳食纤维添加量为7%时,饼干品质最佳,饼干硬度为3158.73±46.30 g,脆性为2648.08±49.62 g,弹性为0.33±0.04,咀嚼性为3834.66±72.57 g,回复性为0.18±0.02,口感较适宜,感官评分为78.8±3.4分,接受度最好。

The “Food Polymer Science” approach to the practice of industrial R&D,leading to patent estates based on fundamental starch science and technology

This article reviews the application of the “Food Polymer Science” approach to the practice of industrial R&D, leading to patent estates based on fundamental starch science and technology. The areas of patents and patented technologies reviewed here include: (a) soft-from-the-freezer ice creams and freezer-storage-stable frozen bread dough products, based on “cryostabilization technology” of frozen foods, utilizing commercial starch hydrolysis products (SHPs); (b) glassy-matrix encapsulation technology for flavors and other volatiles, based on structure-function relationships for commercial SHPs; (c) production of stabilized whole-grain wheat flours for biscuit products, based on the application of “solvent retention capacity” technology to develop flours with reduced damaged starch; (d) production of improved-quality, low-moisture cookies and crackers, based on pentosanase enzyme technology; (e) production of “baked-not-fried,” chip-like, starch-based snack products, based on the use of commercial modified-starch ingredients with selected functionality; (f) accelerated staling of a starch-based food product from baked bread crumb, based on the kinetics of starch retrogradation, treated as a crystallization process for a partially crystalline glassy polymer system; and (g) a process for producing an enzyme-resistant starch, for use as a reduced-calorie flour replacer in a wide range of grain-based food products, including cookies, extruded expanded snacks, and breakfast cereals.

Effects of Chemical and Enzymatic Modification on Dough Rheology and Biscuit Characteristics

ABSTRACT: The effect of addition of sodium meta-bisulfite and a commercial protease on dough rheological properties and biscuit characteristics was studied on 7 biscuit wheat cultivars. Sodium meta-bisulfite (SMS) (360 mg/kg flour) or protease (300 mg/kg flour) was added to semisweet biscuit dough. Rheological studies included creep recovery and shear oscillation. SMS and protease increased maximum strain, recovery strain, and phase tan Δ, and lowered storage modulus, G', and the relative recovery, % recovery. The effects varied among cultivars and between SMS and protease. Biscuit eccentricity (width/length) was significantly reduced by addition of SMS or protease, but the effect varied among the cultivars, and between SMS and protease. Partial least squares regression analysis of the rheological parameters and the dimensional characteristics showed that biscuit contraction and spread were mostly correlated to % recovery of the dough, and protein and gluten content of the flour. Correlations between predicted and measured contraction and spread were r = 0.70 and r = 0.43, respectively.     

灵武长枣果粒对饼干烘焙品质及质构特性的影响

以灵武长枣为主要原料,低筋小麦粉、黄油、玉米油、白砂糖、泡打粉等为辅料,制作灵武长枣营养饼干,重点研究灵武长枣果粒的添加量(0、15、30、45、60、75 g)对饼干烘焙品质及相关物理特性的影响。实验结果表明:适量的添加灵武长枣粒,不仅可以改善饼干的感官品质,还可以改善饼干的质构、吸水率、色度。灵武长枣粒在低添加量时对饼干的感官品质具有改善作用,但当添加量超过45 g后,饼干的感官品质有所降低,灵武长枣粒的添加对饼干的硬度和咀嚼度有促进作用,弹性有下降的趋势,粘聚性和吸水率先升高后降低,对饼干的色度值影响较小。综合分析灵武长枣粒的添加量,以30～45g为宜。添加适量灵武长枣所制的饼干比一般饼干更酸甜可口,香气浓郁,口感酥脆,亮度适宜,色泽均匀,呈现棕黄色,相关物理特性均有所改善。
