羊绒衫质量鉴别四招

羊绒衫的最大特点是轻薄、精巧、细柔、滑润、华贵、雅致，因其纺织难度大，生产成本高，所以，价格一般都比较高。 一招，看商标。羊绒衫在商标上均标注有羊绒含量，如果未标注则不可信。含量越高价格也越高。 二招，掂比重。相同尺寸的羊绒衫与羊毛衫对比，羊绒衫要比羊毛衫轻得多。 三招，查牢固与耐磨性。纯羊绒不够结实，耐磨性差，而羊绒与羊毛混纺的产品，牢固耐磨，织物相对比较结实。 四招，有些厂家用精纺圆机针织坯布，经缩绒后制成毛衫，冒充羊绒衫。这种毛衫手感厚实柔软，与羊绒衫轻薄精巧的特点迥然不同，要注意仔细鉴别。羊…     

Influence of pectin modification on water binding properties

Water can be bound to food components and products as non-freezing, freezing-bound and free water. The interactions are crucial for any application as well as for food consumption and digestion. DSC was applied to examine the amounts of the different types of water bound to pectin, a biomacromolecule that is used as gelling and stabilising agent in many food products. One commercial high-methoxylated citrus pectin and three modified samples, prepared by acidic and alkaline demethoxylation as well as amidation, were tested. The water content of dry samples depended mainly on the molecular parameters, especially the content of hydrophilic groups at the galacturonic acid that was increased by demethoxylation and amidation, as well as on monovalent cations of the pectins. The water–pectin interactions of wetted materials were additionally influenced strongly by the availability of hydrophilic groups that depended on material properties such as amorphous or crystalline state, powder bulk and solid density and porosity as well as particle size, surface and porosity. Small amorphous porous particles, whose polar groups were rapidly available without prior softening and swelling, accelerated water uptake. Non-freezing and freezing-bound water, bound closely to the pectin molecules, depended on the number and type of polar groups. Free water, bound in micro- and macro-capillaries as well as voids within and between the pectin particles, was influenced by hydrophilic as well as hydrophobic groups of the samples. There was a strong impact of the pre-treatment during processing and modification.

Potential Benefits of Edible Berries in the Management of Aerodigestive and Gastrointestinal Tract Cancers: Preclinical and Clinical Evidence

Epidemiological reports as well as experimental studies have demonstrated the significant health benefits provided by regular berry consumption. Berries possess both prophylactic and therapeutic potential against several chronic illnesses, such as cardiovascular, neurodegenerative, and neoplastic diseases. Berries owe their health benefits to phytoconstituents, such as polyphenolic anthocyanins, ellagic acid, and a diverse array of phytochemicals bestowed with potent antioxidant and anti-inflammatory effects as well as the ability to engage a multitude of signaling pathways. This review highlights the principal chemical constituents present in berries and their primary molecular targets. The article presents and critically analyzes the chemopreventive and therapeutic potential of berry extracts, fractions, and bioactive components on various cancers of the gastrointestinal tract (GIT), including esophageal, stomach, intestinal, and colorectal cancers as well as cancers of the upper aerodigestive tract, such as oral cancer. The current status of clinical studies evaluating berry products in several aforementioned cancers is presented. Various emerging issues including dose-ranging and dosage forms, the role of synergy and the usage of combination therapy as well as other relevant areas essential for the development of berry phytoconstituents as mainstream chemopreventive and therapeutic agents against aerodigestive and GIT cancers are critically discussed.

Biovanillin from agro wastes as an alternative food flavour

This review provides an overview of biovanillin production from agro wastes as an alternative food flavour. Biovanillin is one of the widely used flavour compounds in the foods, beverages and pharmaceutical industries. An alternative production approach for biovanillin as a food flavour is hoped for due to the high and variable cost of natural vanillin as well as the limited availability of vanilla pods in the market. Natural vanillin refers to the main organic compound that is extracted from the vanilla bean, as compared to biovanillin, which is produced biologically by microorganisms from a natural precursor such as ferulic acid. Biovanillin is also reviewed as a potential bioflavour produced by microbial fermentation in an economically feasible way in the near future. In fact, we briefly discuss natural, synthetic and biovanillin and the types of agro wastes that are useful as sources for bioconversion of ferulic acid into biovanillin. The subsequent part of the review emphasizes the current application of vanillin as well as the utilization of biovanillin as an alternative food flavour. The final part summarizes biovanillin production from agro wastes that could be of benefit as a food flavour derived from potential natural precursors.© 2012 Society of Chemical Industry
