Tomato powder is an industrial food product obtained by grinding tomatoes that have been dehydrated and then washed.

Industrial Production Process

• Selection. The production begins with the selection of ripe, high-quality tomatoes. The tomatoes are washed to remove impurities and then cut into pieces or slices to facilitate drying.
• Drying. The tomato pieces are dried using industrial dehydrators or solar dryers. The goal is to remove most of the moisture from the tomatoes while preserving their color, flavor, and nutritional value.
• Grinding. The dried tomatoes are then ground into a fine powder. This process may involve several stages of grinding to achieve the desired consistency.
• Sifting. The tomato powder is sifted to remove any coarse particles and ensure a uniform granule size of the final product.
• Quality Control. Before packaging, the tomato powder undergoes quality checks to ensure it meets standards for flavor, color, and purity.

Tomato (Solanum lycopersicum) is one of the most popular vegetables in the world with its 150 million tons produced in 2020.

In first place for production is China, followed by the United States, Turkey and Mexico.

Joseph Campbell produced the first tomato soup in 1897.

The first tomato recipe is attributed to Maria Parloa in her 1872 book Appledore Cook.

The tomato is rich in vitamins A and C and lycopene , the pigment that turns it red and is being studied for the prevention of many types of cancer, as it has antioxidant properties.

It is referred to by many studies as a prevention for prostate cancer (1).

Tomato varieties are many, including: Solanum arcanum, Solanum cheesmaniae, Solanum chilense, Solanum chmielewskii, Solanum corneliomuelleri, Solanum galapagense, Solanum habrochaites, Solanum huaylasense, Solanum neorickii, Solanum pennelli, Solanum perivianum, Solanum pimpinellifolium

Carotenoid content in tomato

GMO tomatoes. Tomatoes have also been genetically modified, but European legislation requires that the term GMO be indicated on the label. There is no distinction in the USA. In terms of the components contained in the transgenic tomato Calcium and Magnesium are more abundant than the natural tomato.

Abstract. The present study reports engineered cold tolerance and toxicity analysis in genetically modified tomato (Solanum lycopersicum L. cv. Pusa Ruby) developed through constitutive over expression of Nicotiana tabacum Osmotin gene. Rate of seed germination, seedling establishment and growth remained unaffected in the transgenic tomato in response to a low temperature (15 °C) treatment, but were significantly (P ≤ 0.05) reduced in the wild type. At reproductive stage, the wild type plants failed to recover at the low temperature (4.0 °C) treatment for 10 days but the transgenic plants survived successfully without any leaf senescence or other visible chilling injury symptoms. The quantitative transcript expression analysis confirmed up regulation of the transgene by 55% in the transgenic plants on cold treatment for 2 h whereas, the transcripts were not detected in the wild type. Containment evaluation under normal environmental conditions revealed similar morphology in both the transgenic and wild type tomato plants however an average fruit yield was higher in the transgenic plants (725.91 ± 39.27 g) than the wild type (679.84 ± 28.80 g). The composition of mature fruits in terms of element content was at par in both the transgenic and wild type except significantly higher Ca and Mg contents in the transgenic fruits than that of the wild type. Further, acute and sub-acute toxicity tests conducted in the adult female Wister rats revealed no mortality or significant changes in general and psychological behaviour, at par food intake and body weight and, normal biochemical, and hematological parameters for animals fed with the wild type or transgenic tomato fruits as compared to the control group, confirming its safety for animal consumption.

Abstract. Tomato (Solanum lycopersicum) is a rich source of lycopene, a carotenoid that confers various positive biological effects such as improved lipid metabolism. Here, we conducted a randomized, double-blind, placebo-controlled, parallel-group comparative study to investigate the effects of regular and continuous intake of a new high-lycopene tomato, a variety named PR-7, for 12 weeks, based on 74 healthy Japanese subjects with low-density lipoprotein cholesterol (LDL-C) levels ≥120 to <160 mg/dL. The subjects were randomly assigned to either the high-lycopene tomato or placebo (lycopene-free tomato) group. Each subject in the high-lycopene group ingested 50 g of semidried PR-7 (lycopene, 22.0-27.8 mg/day) each day for 12 weeks, while subjects in the placebo group ingested placebo semidried tomato. Medical interviews were conducted, vital signs were monitored, body composition was determined, and blood and saliva samples were taken at weeks 0 (baseline), 4, 8, and 12. The primary outcome assessed was LDL-C. The intake of high-lycopene tomato increased lycopene levels in this group compared to levels in the placebo group (p < 0.001). In addition, high-lycopene tomato intake improved LDL-C (p = 0.027). The intake of high-lycopene tomato, PR-7, reduced LDL-C and was confirmed to be safe.

Abstract. The association between diet and prostate cancer (PC) risk, although suggestive, still remains largely elusive particularly in the Asian population. This study sought to further evaluate the possible effects of different dietary factors on risk of PC in Iran. Using data from a prospective hospital-based multicenter case-control study, dietary intakes of red meat, fat, garlic, and tomato/tomato products, as well as thorough demographic and medical characteristics, were determined in 194 cases with the newly diagnosed, clinicopathologically confirmed PC and 317 controls, without any malignant disease, admitted to the same network of hospitals. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were obtained after adjustment for major potential confounders, including age, body mass index, smoking, alcohol, education, occupation, family history of PC, and total dietary calories. Comparing the highest with the lowest tertile, a significant trend of increasing risk with more frequent consumption was found for dietary fat (OR: 1.79, 95% CI: 1.71-4.51), whereas inverse association was observed for tomato/tomato products (OR: 0.33, 95% CI: 0.16-0.65). A nonsignificant increase in PC risk was revealed for dietary red meat (OR: 1.69, 95% CI: 0.93-3.06). For garlic consumption, a borderline reduction in risk was observed (OR: 0.58, 95% CI: 0.32-1.01; P = 0.05). In conclusion, our study supports the hypothesis that total fat may increase PC risk and tomatoes/tomato products and garlic may protect patients against PC.
