Populations like to have a healthy diet without changing their fundamental dietary pattern. The importance of dietetic foods with health potential has increased the interest of consumers on crops with nutraceutical messages. Several plant food products from selected ancient crops like flax, chia, black cumin, sunflower, sesame, and pumpkin seeds co...

Hot pepper (Capsicum annuum) fruits, usually termed as chili, have been used since ancient times as food vegetables, flavoring ingredients, natural colorants, and in traditional medicines. Nowadays, a wide variation of sweet and pungent peppers are consumed worldwide in a large variety of forms. Interestingly, the most important hot pepper at the g...

Chia seeds (Salvia hispanica L.) have high amounts of nutraceutical compounds and a great commercial potential. The aim of this work was to identify proximate composition, fatty acids profile, total phenolics and antioxidant capacity of chia, as well the protein fractions and determine their antihypertensive potential. The seeds exhibited high cont...
Article
Background Nopal (Opuntia spp.) is by excellence the most utilized cactus in human and animal nutrition. It is also a very noble plant; its main physicochemical, nutritional and nutraceutical characteristics allow the use of nopal in diverse food applications. Special focus has been given over the past decades in the use of Opuntia for the treatmen...

Salvia hispanica (chia) constituted an important crop for pre-Columbian civilizations and is considered a superfood for its rich content of essential fatty acids and proteins. In this study, we performed the first comprehensive comparative transcriptome analysis between seeds from cultivated varieties and from accessions collected from native wild...

This review reported an updated survey on the molecular functional properties of bioactive peptides derived from different Latin American ancient grains such as Maize, common Bean, Amaranth, Quinoa and Chia seeds. Seed storage proteins encrypted in their sequences diverse peptides associated with a wide range of benefit effects on the human health...

Canary seed (Phalaris canariensis) is used to feed birds but it has been recently considered a promising cereal with nutraceutical potential for humans. The aim of this work was to analyze the protein fractions from canary seed flour and from milk substitutes (prepared by soaking the seeds in water 12 and 24 h), and to evaluate antioxidant and anti...

Huitlacoche mushroom (composed by the fruiting bodies growing on the maize ears from the basidiomycete Ustilago maydis) is a culinary delicacy with a great economic and nutraceutical value. In this work, phenolic content, antioxidant activity, ergosterol and fatty acids profile from huitlacoche produced in 15 creole and in one hybrid maize genotype...
Chapter
Salvia hispanica L. commonly known as chia is an ancient food that provides a balanced amount of nutrients composed of insoluble fiber, high ω-3/-6 fatty acids, proteins with an excellent quality of amino acids, high content of antioxidants, and minerals. In first instance, chia seeds contain a coat mucilage that covers completely all seed nutrient...

Mushrooms have been consumed since earliest history; ancient Greeks believed that mushrooms provided strength for warriors in battle, and the Romans perceived them as the " Food of the Gods. " For centuries, the Chinese culture has treasured mushrooms as a health food, an " elixir of life. " They have been part of the human culture for thousands of...

Huitlacoche galls were produced in 15 creole maize genotypes harvested at two stages of development, 23 and 28 days after inoculation, and in a hybrid genotype harvested at six stages of development. Raw and cooked galls were evaluated for proximate constituents, carbohydrate composition and antimutagenic activity. Huitlacoche grown in creole maize...

The methylotrophic yeast Pichia pastoris was used to express an 11S seed globulin from Amaranthus hypochondriacus. Three different plasmids were tested for expression of amarantin. One of them, which included the untranslated regions (UTR) of the full cDNA, failed to express the amarantin under tested conditions, whereas the other plasmids, one wit...

In vitro micropropagation Opuntia cactus plants, whose young stems are consumed as vegetables, is reported. Cladode explants from three Opuntia genotypes, were cultivated in MS medium containing BA and GA3. Shoots produced were used as secondary explants and BA added at different concentrations to induce shoot development. 0.5 M BA was the best for...

Chemical and biochemical changes were studied in ripening prickly pears from three Opuntia morphospecies with different ripening behaviour: Naranjona (O. ficus-indica), Blanca Cristalina (Opuntia sp.), and Charola (O. streptacantha), of early, intermediate, and late ripening, respectively. At fullyripe stage (commercial maturity), Blanca Cristalina...
Article
Huitlacoche was produced by injection of two compatible isolates of Ustilago maydis into ears of 19 maize hybrids and analyzed for proximate composition and fatty acid content. Protein content ranged from 10.0 to 14.5% (dry basis) and fat content from 2.7 to 6.5%. Samples showed high contents of oleic and linoleic acids.
