Development of a healthy low-fat fish sausage containing dietary fibre

INTERNATIONAL JOURNAL OF FOOD SCIENCE & TECHNOLOGY, Issue 2 2008
Carlos Cardoso
Summary In order to develop a healthy low-fat fish sausage containing dietary fibre (DF), three fundamental changes were made to an ordinary pork sausage recipe: incorporation of 4% (w/w) of Swelite® (a DF obtained from inner pea), different levels of pork meat replacement (0%, 50% and 100%) by hake mince and the combination of varying amounts of Fibruline® (a DF obtained from chicory root) and hake mince (Fibruline: additional hake mince, 2.6:5.2, 5.2:2.6 and 7.8:0.0, % w/w) as a substitute for pork fat. It was found that the addition of Swelite to pork sausage favoured greater gel strength and hardness. On the contrary, increasing levels of pork meat replacement by hake reduced the sausages' gel strength and hardness. Finally, sausages without pork fat showed promising textural and colour parameters. High-Fibruline sausages were less cohesive and chewable than pork fat sausages (control), but also exhibited a greater gel strength. Low-Fibruline ones presented almost all textural properties similar to the control, with exception of hardness and gumminess. Therefore, regarding some key textural parameters, it was possible to produce low-fat fish sausages similar to the ordinary pork sausages. [source]


Effect of transglutaminase and carrageenan on restructured fish products containing dietary fibres

INTERNATIONAL JOURNAL OF FOOD SCIENCE & TECHNOLOGY, Issue 11 2007
Carlos Cardoso
Summary The inclusion of various levels of a microbial transglutaminase or a carrageenan additive to restructured hake products with or without dietary fibre (obtained from inner pea or chicory root) was studied. These experiments were aimed at producing technologically innovative restructured fish products with improved textural and colour properties. It was found that the addition of transglutaminase, up to 0.5% (w/w), favoured better textural properties, particularly, at 0.1% (w/w) level or above. On the other hand, restructured product with a dietary fibre content of 4% (w/w) and carrageenan addition, up to 2% (w/w), exhibited increased hardness. This can be particularly interesting for those products containing chicory root inulins as this fibre presented an adverse effect on hardness. Regarding colour, higher carrageenan contents caused a slight but significant colour change in the product, making it redder (for products containing Swelite and Fibruline) and more yellow (only concerning Swelite).

Prebiotic inulin-type fructans: nutritional benefits beyond dietary fibre source

NUTRITION BULLETIN, Issue 3 2008
H. Alexiou
Summary For several years, there has been an increasing awareness of the fundamental role that the complex bacterial ecosystem plays in our health. Inulin and oligofructose are prebiotic dietary fibres naturally present in the chicory root. They escape metabolism in the small intestine, and their selective fermentation by the human colonic microflora leads to a shift in the composition of the indigenous bacterial ecosystem, in favour of health-promoting bifidobacteria. In addition to their dietary fibre effects on improved bowel regularity, several physiological advantages are linked to their specific pattern of fermentation in the colon, including improved mineral absorption, enhanced natural host defences and colonic protection, improved gut health, and beneficial influence on appetite regulation. The aim of the present review was to highlight the nutritional benefits of inulin-type fructans, focusing on key physiological functions. [source]


Plant fructans stabilize phosphatidylcholine liposomes during freeze-drying

FEBS JOURNAL, Issue 2 2000
Dirk K. Hincha
Fructans have been implicated as protective agents in the drought and freezing tolerance of many plant species. A direct proof of their ability to stabilize biological structures under stress conditions, however, is still lacking. Here we show that inulins (linear fructose polymers) isolated from chicory roots and dahlia tubers stabilize egg phosphatidylcholine large unilamellar vesicles during freeze-drying, while another polysaccharide, hydroxyethyl starch, was completely ineffective. Liposome stability was assessed after rehydration by measuring retention of the soluble fluorescent dye carboxyfluorescein and bilayer fusion. Inulin was an especially effective stabilizer in combination with glucose. Analysis by HPLC showed that the commercial inulin preparations used in our study contained no low molecular mass sugars that could be responsible for the observed stabilizing effect of the fructans. Fourier transform infrared spectroscopy showed a reduction of the gel to liquid-crystalline phase transition temperature of dry egg PtdCho by more than 20 °C in the presence of inulin. A direct interaction of inulin with the phospholipid in the dry state was also indicated by dramatic differences in the phosphate asymmetric stretch region of the infrared spectrum between samples with and without the polysaccharide.

Fate of vinclozolin, thiabendazole and dimethomorph during storage, handling and forcing of chicory

PEST MANAGEMENT SCIENCE (FORMERLY: PESTICIDE SCIENCE), Issue 2 2010
Pieter Spanoghe
Abstract BACKGROUND: As part of ongoing research for a sustainable production of Belgian endives, the fate of three fungicides during storage, handling and forcing of witloof chicory roots was investigated. Storage roots are protected against Sclerotinia sp. Fuckel and Phoma exigua var. exigua Desm. by means of vinclozolin and thiabendazole respectively. During hydroponic forcing, the most imminent pathogen is Phytophthora cryptogea Pethybr. & Laff., which is controlled by the use of dimethomorph. RESULTS: Vinclozolin and thiabendazole concentrations on roots remained constant during storage at ,1 °C. Dermal exposure of the workers in hydroponics was exceeded. Vinclozolin and thiabendazole residues were not detected 2 weeks after hydroponic forcing; dimethomorph was still detected at harvest. At harvest, the vinclozolin concentration in the chicory heads was below the maximum residue limit, but the chicory roots contained residues much above the thiabendazole and dimethomorph maximum residue level. CONCLUSION: Vinclozolin and thiabendazole residues applied before storage are still present on the roots at the start of the forcing cycle. During the set-up of chicory roots, preventive measures are recommended, as effects of repeated human exposure to low doses of applied fungicides cannot be excluded. Dimethomorph applied at the start of the hydroponic forcing is the only pesticide detected in the drainage water at harvest. The chicory heads were safe for human consumption. However, more attention should be paid to the residues of fungicides in the roots used for cattle feeding. Copyright © 2009 Society of Chemical Industry [source]
