Glucose fruit

These drinks are prepared with or without the use of fruit juice or fruit extracts by the addition of natural fruit essences and sugar (sucrose or glucose), fruit acids and soda or mineral water. They are also consumed without added carbon dioxide, either cold or warmed. The drinks are usually colored. Lemonades made with the addition of fruit juices contain at least half the amount of fruit juice normally contained in fruit juice drinks. 

M.p. 190-192 C. The enolic form of 3-oxo-L-gulofuranolactone. It can be prepared by synthesis from glucose, or extracted from plant sources such as rose hips, blackcurrants or citrus fruits. Easily oxidized. It is essential for the formation of collagen and intercellular material, bone and teeth, and for the healing of wounds. It is used in the treatment of scurvy. Man is one of the few mammals unable to manufacture ascorbic acid in his liver. Used as a photographic developing agent in alkaline solution. 

D-fructose, C HijOo. Crystallizes in large needles m.p. 102-104 C. The most eommon ketose sugar. Combined with glucose it occurs as sucrose and rafftnose mixed with glucose it is present in fruit juices, honey and other products inulin and levan are built of fructose residues only. In natural products it is always in the furanose form, but it crystallizes in the pyranose form. It is very soluble in... 

Polysaccharides are macromolecules which make up a large part of the bulk of the vegetable kingdom. Cellulose and starch are, respectively, the first and second most abundant organic compounds in plants. The former is present in leaves and grasses the latter in fruits, stems, and roots. Because of their abundance in nature and because of contemporary interest in renewable resources, there is a great deal of interest in these compounds. Both cellulose and starch are hydrolyzed by acids to D-glucose, the repeat unit in both polymer chains. 

D-Glucitol, the alditol produced by reduction of D-glucose, is itself a naturally occurring substance present in many fruits and berries. It is used under its alternative name, D-sorbitol, as a sweetener and sugar substitute in foods. 

The alcohol in most liqueurs is ethanol, C2H5OH. It is produced by foe fermentation of the glucose in fruit or grain. 

The wine in the goblet can be produced by the fermentation of glucose (present in all the fruits shown in the painting) to ethyl alcohol. 

Sucrose, the compound we call sugar, is the most common disaccharide. One of the monomer units in sucrose is a-glucose. The other is fructose, a monosaccharide found in honey and natural fruit juices.

D-Fructose Fruit juices. Honey. Hydrolysis of cane sugar and of inulin (from the Jerusalem artichoke). Can be changed to glucose in the liver and so used in the body. Hereditary fructose intolerance leads to fructose accumulation and hypoglycemia. 

Since anthocyaifins acylated with aliphatic acids are sensitive to acids, as verified, for example, in fruits of R suberosa when extracted with methanol containing 0.1% HCl," their occurrence in foods may be underestimated. Malonyl acylation in glucose at its position 6 was found in anthocyanins from blood... 

We observed that this activity is maximum five days after culture inoculation. Its biosynthesis is influenced by the glucose concentration. It is also stimulated hy pectin concentrations similar to the ones seen in fruit juices. 

Additionnally, we show that the PG activity of the SCPP strain is regulated. It is stimulated by polyglacturonic acid concentrations similar to the ones seen in various fruit juices. On an industrial point of view, this induction would be diminished by the elevated glucose concentrations found in these fruit juices when compared to the pectin concentrations. Basal activities would be sufficient to eliminate all pectins and obtain juice stabilization. It would also have been interesting to study the effect of glucose concentrations of 15% and 20% (concentrations found in fruit juices, beers and ciders) on the PG activity of the SCPP strain.

Fruits and vegetables generally possess a high soluble DF/insoluble DF ratio that is associated with slow glucose absorption, high colonic fermentability, lower serum cholesterol levels, and enhancement of immune functions (McCleary and Prosky 2001). 

SDF content is high in fruits, vegetables, and legumes and is associated with colonic degradation and high fermentability, slow glucose absorption, enhanced immune functions, and lower serum cholesterol levels. IDF is predominant in cereals and legumes fermentation is slow and incomplete, and they have more pronounced effects on bowel habit.

Tables have been published relating Baume, Brix and specific gravity. As density is temperature dependent it is necessary to either bring the syrup to a fixed temperature or, as is more common in practice, to use temperature correction factors or tables. The relationship between density and concentration is slightly different for invert sugar or glucose syrups. The Brix scale is sometimes applied to products that are not sucrose syrups, such as concentrated fruit juice. Recipes are certainly in use that state boil to x Brix . In practice these instructions mean that the material should give the same reading as a sugar syrup of that concentration. As often happens in confectionery these practices have been proved to work empirically.
