RAISINS
Raisins are essentially
dehydrated grapes (fresh
grapes usually contain about 80% water, while in raisins, the moisture content decreases to 15% due to drying), so the nutrient composition of these two products is similar (raisins are rich in vitamins, mineral elements, proteins, and carbohydrates from grapes are concentrated).
However, there are certain
differences in the nutrient composition of grapes and raisins. During the drying process,
grapes undergo changes in the composition of sugars, enzymes, and many pigments. For example,
grapes contain pentoses as the main monosaccharides, while raisins contain hexoses. The enzyme polyphenol oxidase, present in grapes, is absent in raisins. Chlorophyll a, chlorophyll b, xanthophylls (lutein and its isomer zeaxanthin), alpha- and beta-carotenes are present in raisins in significantly lower amounts. The content of vitamins C, E, and K is lower in raisins compared to
grapes, unlike the B vitamins, nicotinic acid, and choline, although in the latter cases, it is not high. The reduction in some vitamins is likely related to their degradation due to high temperatures and enzymes during the drying process.
Like
grapes, raisins
are not very rich in vitamins, but
are distinguished by a high content of several mineral elements, among which the following prevail:
boron (in 100 g – 2017.9% of the daily norm),
rubidium (respectively – 176.0%),
strontium (90.4%),
cobalt (80%),
vanadium (62.5%),
silicon (61.7%),
copper (34.0%),
potassium (32.2%),
arsenic (25.0%),
iron (21.3%),
molybdenum (20.0%),
chromium (17.6%),
nickel (17.0%),
manganese (15.8%),
phosphorus (14.4%),
magnesium (8.6%),
thallium (7.5%).
Raisins are very rich in carbohydrates (in 100 g – 22.3% of the daily norm), mainly – mono- and disaccharides (respectively – 118.4%), among which glucose (in 100 g – 277.5% of the daily norm) and fructose (respectively – 84.8%); as well as fiber (15.4%) and pectin (32.0%); contains small amounts of starch (in 100 g – 2.7 g) and sucrose (respectively – 0.45 g).
The total purine base content in 100 g is quite high and amounts to 35.7% of the daily norm, which should be considered by patients with gout.
Raisins
contain toxic mineral elements, especially they can accumulate strontium (in 100 g – 90.4% of the daily norm),
arsenic (respectively – 25.0%) and
thallium (7.5%).
