There is an increasing demand for healthier foodstuff containing specific compounds such as Polyunsaturated Fatty Acids (PUFAs). In the case of PUFAs, protection against oxidative degradation is challengeable and microencapsulation emerges as an alternative. Mayonnaises containing microencapsulated oils could be a source of PUFAs. The objective was to formulate mayonnaises containing microencapsulated chia seeds oil, pumpkin seeds oil or baru oil. Micrometric particles with high encapsulation efficiency were produced and thermal analyses indicated an increased thermal stability of all oils after encapsulation...

Dietary plant foods are characterized by a vast molecular diversity of glycosylated sterols (SG) that differ in the structure of the steryl backbone. The identification of these polar steryl conjugates represents a major challenge as they are structurally highly similar, and commercial standards are limited to a few naturally abundant species. Spectral databases do not yet contain MS/MS spectra of these sterol conjugates obtained by electrospray ionization (ESI), which would facilitate their reliable identification...

We investigated if pumpkin and flaxseeds could improve postprandial glycemic, food intake, and appetitive responses. Herein, we hypothesize based on the literature that pumpkin seed has potential to lower postprandial glycemic effects. Therefore, we conducted a randomized, single-blind, placebo-controlled, crossover design study involving normoglycemic adults (food intake: n = 25; glycemia: n = 15). Three high-carbohydrate mixed meals presenting no seed (control [C]) or 65 g of the tested seeds (pumpkin seed [P] or flaxseed [F]) were consumed in 3 nonconsecutive days...

BACKGROUND: The induction of skin pigmentation by ultraviolet (UV) radiation has been shown to result from factors secreted from UV-exposed keratinocytes that enhance melanogenesis in melanosomes (MSs) and stimulates their transfer to keratinocytes. Among those factors, it has been reported that α-melanocyte stimulating hormone, which is converted from the precursor proopiomelanocortin (POMC) following UV exposure, stimulates the transfer of MSs from melanocytes to surrounding keratinocytes...

Background : Iron deficiency is a public health problem in many low- and middle-income countries. Introduction of agro-industrial food by-products, as additional source of nutrients, could help alleviate this micronutrient deficiency, provide alternative sources of nutrients and calories in developed countries, and be a partial solution for disposal of agro-industry by-products. Methods : The aim of this study was to determine iron bioavailability of 5 by-products from Brazilian agro-industry (peels from cucumber, pumpkin, and jackfruit, cupuaçu seed peel, and rice bran), using the in vitro digestion/ Caco-2 cell model; with Caco-2 cell ferritin formation as a surrogate marker of iron bioavailability...

Despite the seriousness of schistosomiasis, its treatment depends only on praziquantel (PZQ), which has begun to lose its efficacy against the emergent Schistosoma mansoni-resistant strains. Therefore, the discovery of a novel schistosomicidal drug is an urgent priority. This study was designed to evaluate treatment with Cucurbita pepo L. (pumpkin) seed oil (PSO) alone and combined with PZQ against S. mansoni in experimentally infected mice. The study involved five groups: GI was the normal control; GII was the infected control; GIII was treated with an oral dose of PZQ of 500 mg/kg/day for two successive days, starting in the sixth week post infection; GIV was treated with an oral dose of PSO of 50 mg/kg/day for four weeks, starting in the fourth week post infection; and GV was treated with combined PSO-PZQ...

Nigeria is the world's largest producer of yam, cassava, cocoyam/taro, beans/cowpea, egusi/melon seeds and among the largest producers of groundnut/peanut, plantain, corn/maize and ugwu/pumpkin leaves. These food crops generate unavoidable food wastes that can contribute to environmental degradation through unsanctioned waste disposal methods. Such food wastes can be utilised as feedstock for the anaerobic digestion (AD) process to produce renewable energy. In order to determine the suitability of the food wastes as biofuel feedstock, they were experimentally analysed...

An in vitro dialyzability approach has been undertaken to elucidate the bioavailable fraction of the total polyphenols (TPs) of edible nuts and seeds. The TP contents in samples and in dialyzates were assessed by the Folin-Ciocalteu spectrophotometric method. Antioxidant activity was determined in selected samples, using a modified method against Trolox®. TPs and antioxidant activity in nuts/seeds were determined after applying a pressurized liquid extraction sample pre-treatment. High dialyzability ratios were assessed in most nuts/seeds (TP dialyzability percentages within the 25-91% range)...
