“…Strawberry (Fragaria × ananassa) fruit is a rich source of polyphenolics, a group of natural secondary metabolites that have been claimed to have a beneficial effect on human health, − although the importance of antioxidant activity for health aspects has been doubted lately in recent studies . Polyphenolics differ greatly in molecular size, as the group includes very simple structures such as hydroxycinnamic and hydroxybenzoic acids as well as flavonoids and large polymers of high molecular weight such as proanthocyanidins.…”

Polyphenolics are important secondary metabolites in strawberry as they fulfill a wide variety of physiological functions and are beneficial to human health. Seventeen structurally well-defined phenolic compounds including phenylpropanoids, flavonols, flavan-3-ols, and anthocyanins were individually analyzed by LC-MS in the ripe fruits of two cultivars of the commercial strawberry (Fragaria × ananassa Duch., Rosaceae) as well as in accessions of F. vesca, F. moschata, and F. chiloensis. Metabolic analysis revealed that the majority of the compounds analyzed accumulated in a genotype-dependent manner. Transcriptional studies of genes encoding for enzymes of the biosynthetic pathway such as phenylalanine ammonia-lyase, cinnamic acid 4-hydroxylase, chalcone synthase, and flavonoid 3'-hydroxylase could partially explain the different levels of polyphenolics observed in the Fragaria species. The results can provide a sound basis for selecting markers for the development of cultivars with high phenolic content, which can be of value for the food industry.

“…More significantly, in vitro studies indicate that organic foods can reduce the risks of 'cancer' in humans. Extracts from organic strawberries showed higher anti-proliferative activity against 'colon cancer' and 'breast cancer' cells than did the extracts from conventional strawberries (Olsson et al, 2006). Tomato is one of the most 'protective food' due to excellent source of balanced mixture of minerals and antioxidants, including vitamin C, total carotene and lycopene.…”

“…Organic farming systems with the aid of nutritive bio-fertilizer like 'earthworms vermicompost' can give very 'high food productivity' with significantly 'higher nutritional quality' while also improving the physical, chemical and biological properties of soil. Organic foods have also been found to be 'protective' to human health even against 'colon cancer' and 'breast cancer' (Olsson, 2006).…”

Agrochemicals which ushered in the 'green revolution' in the 1950-60's, boosted food productivity, but at the cost of environment and society. It increased food production but also destroyed the 'physical, chemical and the biological properties' of soil over the years of use. It killed the beneficial soil organisms and also impaired the power of 'biological resistance' in crops making them more susceptible to pests and diseases. No farmland of world is free of toxic pesticides today. Over the years it has worked like a 'slow poison' for the soil and society. According to UNEP and WHO nearly 3 million people suffer from 'acute pesticide poisoning' and some 10 to 20 thousand people die every year from it in both the developed and the developing countries. Organic farming by earthworms (Sir Charles Darwin's 'friends of farmers') can provide a sustainable and also highly economical solution to the various problems created by the destructive agrochemicals in farm production. Earthworms vermicompost are scientifically proving to be an 'extraordinary powerful growth promoters and protectors' for crops (5-7 times over other bulky organic fertilizers and 20-40 % higher over chemical fertilizers). They are rich in NKP, micronutrients, beneficial soil microbes like 'nitrogen-fixing' and 'phosphate solubilizing' bacteria, 'mycorrhizal fungi', humus and growth hormonesauxins, gibberlins and cytokinins. It has very high 'porosity ', 'aeration', 'drainage' and 'water

“…Por otra parte, poseen compuestos bioactivos de interés nutricional y elevada actividad antioxidante, que pueden conferir importantes beneficios a la salud humana (Ferreyra et al, 2007). Diversos estudios muestran que el consumo de frutillas inhibe bacterias patógenas, tales como Salmonella y Staphylococcus (Badjakov et al, 2008), presenta acción anticarcinógena (Cantillano et al, 2012) y anticoagulante (Olsson et al, 2007) y reduce el riesgo de enfermedades cardiovasculares (Erlund et al, 2008). Entre los fitoquímicos responsables de estas acciones, se incluyen compuestos fenólicos tales como las antocianinas, quercitina, pro-antocianidinas, taninos hidrolizados y otras moléculas relacionadas con los flavonoides (Ondarza-Beneitez y Ciapara-Higuera, 2016).…”

La frutilla (Fragaria ananassa) posee compuestos bioactivos de interés nutricional y elevada actividad antioxidante, que pueden conferir importantes beneficios a la salud humana. Sin embargo, son productos altamente perecederos. El objetivo de este trabajo fue deshidratar frutillas por secado convectivo, para extender su vida útil. Se ensayaron tres temperaturas del aire de secado: 60º, 70º y 80 ºC y una velocidad de 0,7 m/s. Para caracterizar las harinas obtenidas, se midió el color, la capacidad antimicrobiana y antioxidante, el contenido de antocianinas y de compuestos fenólicos totales (CPT), en extractos hidroalcohólicos generados por agitación. La harina de frutillas obtenida conservó o incrementó el contenido de CPT y la capacidad antioxidante, particularmente cuando la materia prima se deshidrató a 70 ºC. El contenido de antocianinas disminuyó y el color también fue modificado. Se evidenció la potencialidad de las harinas de frutillas para su aprovechamiento como ingrediente en la formulación de alimentos, por sus aportes de compuestos bioactivos.
