The important carotenoid in tomatoes i. e. lycopene having antioxidant capability has led to promising results in decreasing the risk of some illnesses and diseases. The tomato processing waste (pomace) is considered to be the potential raw material for production of natural lycopene. The purpose behind conventional solvent extraction method is a cheaper technology as compared to other modern technologies. It can be satisfactorily intended in the food systems as a functional ingredient. For the maximum recovery of lycopene from tomato pomace was carried out by selecting the suitable solvent system, temperature-time combination and feed to solvent ratio, i.e. Acetone: Ethyl acetate (1:1), 40 ?C/5 h and 1:30 (w/v). By using optimized solvent extraction process and had the lycopene content 611.105 mg/100 g, purity 81.319 %, refractive index 1.37604 and colour value 5.59 L*, 8.00 a*, 6.14 b*. There was 53.4 % reduction in the lycopene content after 60 days of storage at room temperature while at refrigerated condition, it was found safe with just 2.6 % reduction in lycopene content.
Lycopene is highly unsaturated, open-chain carotenoid found abundantly in tomatoes. Research interests into properties & health benefits of lycopene have been growing, bringing attention to content of lycopene in food. The purpose of this work was to develop efficient & accurate protocol that can measure lycopene using HPLC, and establish relationship with Vis/NIR reflectance spectroscopy measurement. Accordingly, mobile phase composition ACN/MeOH (50:50, v/v)+ TEA 9 µM; extraction solvents hexane/acetone/ethanol (50:25:25, v/v/v); re-dissolving residue in THF, followed ACN/MeOH (15:30:55, v/v/v); flow rate 0.6 mL/min and ?detection 472 nm were showed most suitable for lycopene determination in tomato. This method has achieved best characteristic spectra profile with precision (RSD > 15), accuracy & recovery (? 81.7%) and sensitive detection limit (0.0156 ?g/mL) within separation of ~ 21 minutes. Finally, the established method was applied to selected tomato cultivars and a wide range of lycopene content 1.91 to 8.23 mg/100g was observed. Besides, although HPLC is most accepted method; Vis/NIR combined with multivariate techniques has showed potential for determining lycopene.
Lycopene is a natural pigment that imparts red color to tomato, guava, watermelon, and pink grapefruit. Lycopene acts by various mechanisms to protect body cells against oxidative damage, and thus, lycopene may play a preventive role in different kinds of chronic cancers and cardiovascular diseases. Tomatoes (especially deep-red fresh tomato fruits) and tomato products are considered the most important source of lycopene in many human diets . Therefore most of the research on lycopene focus on tomato and tomato products. The present study is to estimate the lycopene content from the fresh tomato fruit and processed tomato products .It is aimed at the comparison of lycopene content before and after processing of the tomatoes.
Tomatoes are consumed both in raw, as salad and processed form. The popular processed products of tomato are ketchup, sauce, salsa, puree, juice and soup.During processing of tomato in to various products 10-30 per cent of their weight becomes waste or pomace which mainly constitutes its peel and seeds. The by-products of tomato processing industries (peels and seeds) pose a problem in its disposal, more so when it is wet. Many studies carried out to assess the potential of utilization of by-products for their inclusion in human diet showing promising results in reduction of the industrial costs and also controlling the pollution problem connected with food processing. A study was conducted to estimate tomato waste generated while processing by different methods, standardize extraction process of lycopene and use it for fortification. Wet and dry peel were used directly for extraction of lycopene using organic solvent and also by enzymatic pre-treatment before solvent extraction. The extracted lycopene was used for fortification of tomato beverages (juice and soup) and changes in their nutritive quality was studied during storage.
The aim of this study is to produce external standards for Z-lycopene induced by processing of tomatoes. The general goal of this thesis was to produce external standards for Z-lycopene isomers which occur in processed tomatoes. In order to reach this goal several questions needed to be answered: Are Z-lycopene isomers formed during processing of tomatoes? How can Z-lycopene isomers, formed during processing of tomatoes, be produced with high yield? Is it possible to collect the Z-lycopene isomers separately? How can the targeted isomers be obtained as a pure solid? What is the position of the Z-double bond of the Z-lycopene isomers? What is the extinction coefficient of the Z-lycopene isomers?
Lycopene is the carotenoid which gives tomatoes and other red fruits their characteristic colour. It is one of the most powerful antioxidants and singlet oxygen-quenching agents. Lycopene has been found to be of great medical importance, having various anticancer effects and it is able to ameliorate several other medical conditions. Lycopene had also been found to be very useful in the food industry where it is used as food additives, colourant and functional food. Lycopene, has been the focus of considerable attention for its potential health benefits (Shi et al. 2002; Rao and Rao, 2004). Results from epidemiological and experimental studies support the view that lycopene may provide protection against cardiovascular disease and certain types of cancer (Giovannucci, 2005; Omoni and Aluko, 2005). Lavecchia and Zuorro (2011) reported the growing demand for natural lycopene and therefore considerable interest has been directed to the possibility of obtaining lycopene from tomato processing waste. This growing demand for natural lycopene has led us to device an alternative means for the extraction of lycopene using enzymes.
Prostate Cancer is the second most common cancer that affect men after lung cancer. The cause of prostate cancer is largely unknown but the risk of developing it increases after the ages of 50 and 40 years among Whites and Blacks respectively. Prostate cancer develops very slowly, takes several years to manifest and often spreads to other parts of the body with very low cure rates by the time of diagnosis. Actually, most men die with this cancer and not of it. The survival rate of prostate cancer is between 5 and 10 years for all stages of the disease. Early detection of prostate cancer before it becomes clinically significant, markedly improves cure rates. Two screenings for prostate cancer; Digital Rectal Exam (DRE) and Prostate Specific Antigen (PSA)test are recommended annually for men 40 years and older for early detection and prevention of prostate cancer. Diet low in fat, high in vegetables and fruits, avoiding excessive meat eating and alcohol abuse may reduce a man's risk of prostate cancer. Your health care provider can give you more information about prostate screening and prevention of prostate cancer.
