The lycopene content in pulp ad peel of five fresh tomato varieties
The lycopene content in pulp and peel of five fresh tomato cultivars, most common on Croatian market, was determined by spectrophotometry and the high-performance liquid chromatography (HPLC). Peels from the raw tomatoes contained more lycopene (expressed on a fresh basis) than the pulps: the ratio was 3.75±1.08 for spectrophotometric and 3.50±0.95 for HPLC measurements. Comparison of the results of lycopene content expressed on a dry weight basis revealed that the peel from raw tomato contains 1.74±0.36 times (spectrophotometry) more lycopene than the pulp as compared to a factor of 1.61±0.24 obtained by HPLC analysis. Fraction of the pulp in a whole tomato was found to vary between 89.9 and 95.2%, while that of tomato peel was between 4.9 and 10.1%. Nutritional habits in Croatia often include tomato-based food, all year around, prepared partlyof whole fresh tomatoes (including peel), partly of industrial tomato products (from which peel is often excluded). This study provides evidence that the peel of one of the most common varieties of tomatoes on Croatian market is richer in lycopene than the pulp and, moreover, that a diet including 100 g of raw tomatoes provides 1.35±0.29 mg lycopene from pulp as compared to 0.35±0.18 mg lycopene from tomato peel. In addition, results of this study will be useful in further attempts to quantify lycopene content of intact, whole tomatoes by means of the nondestructive, photoacoustic metho
Development of reduced-fat cheeses with the addition of Agave fructans
Cheeses containing Agave fructans were compared with both full-fat and reduced-fat samples without fructans. Microstructure results showed that the cheeses obtained were very similar to the control samples (without fructans), even the full-fat control sample, demonstrating the texturing role of the carbohydrates. Regarding the composition, a moisture content of 47.96 ± 1.45 and a good protein retention with a low-fat content were found. Therefore, the cheese yield was not adversely affected, and no significant differences were observed in sensory aspects. Considering the health benefits of fructans and their abundance, this development could represent an innovation for dairy industry.Fil: Palatnik, Diana Raquel.
