Physicochemical, nutritional properties, and antioxidant potential of 'limilla' fruit ( var. schmidelioides (Schltdl.) Engl.).

inhabits humid oak and oakpine forests in the State of Michoacán (Mexico). The fruit of is edible and is traditionally used in the preparation of soft drinks, ice pops, ice creams and 'atole'. The objective of the present investigation was to carry out a physical and chemical characterization and analysis of the antioxidant capacity of fruit.

The Phytoestrogenic Effect of Hibiscus sabdariffa Involves Estrogen Receptor α in Ovariectomized Wistar Rats.

The calyxes of Hibiscus sabdariffa present multiple pharmacological effects primarily attributed to their high anthocyanin content; however, little is known about their phytoestrogenic effect. Ovarian hypofunction (OH) is a process characterized by the rapid detention of the production of ovarian hormones, which compromises reproductive and cognitive functions. Hormone replacement therapy (HRT) efficiently compensates for OH; nevertheless, questions have been raised on its secondary effects and safety.

Physicochemical, calorimetric and texture profile characteristics of various gluten-free flours.

It is important to understand how the composition and structure of proteins from other flours differ from proteins in wheat, in order to have a better option to substitute gluten products with gluten-free food products. The aim of this study was the characterization of gluten-free flours and comparison of their rheological and calorimetric properties against wheat flour, for its use as gluten-free alternative. Chemical composition analysis, water solubility index (WSI), water absorption index (WAI), texture and calorimetric profile were determined.

Aloe Vera and Nopal mucilage on the reduction of agglomeration during spray drying and storage of blackberry and raspberry extracts.

The objective of this investigation was to evaluate the influence of two carrier agents, Nopal and Aloe Vera mucilage on the physicochemical properties and stability of blackberry and raspberry powders obtained by spray drying. A pilot scale spray dryer with a feed flow of 20 L/h and an atomization speed of 28,000 rpm was used. The inlet and outlet air temperatures were from 180 to 80 °C, respectively.

Effects of calyces on spatial memory and hippocampal expression of BDNF in ovariectomized rats.

Ovarian hypofunction is characterized by decay in brain-derived neurotrophic factor (BDNF), a neurotrophin associated with cognitive and memory function. Hormone replacement therapy is the most common treatment to counteract the negative effects of ovarian insufficiency; however, this therapy may increase the odds of endometrial cancer, blood clots, stroke, and breast cancer. Therefore, a safer alternative to synthetic estrogens is needed.

Effect of the temperature on the spray drying of Roselle extracts (Hibiscus sabdariffa L.).

The effect of the drying temperature on the volatile components and sensory acceptance of the Roselle (Hibiscus sabdariffa) extract in powder was investigated. The Roselle extraction was carried out by maceration with 7 L of 30% ethanol (v/v), 560 g of fresh Roselle calyces for 168 h. The Roselle extracts were spray dried at different temperatures 150, 160, 170, 180, 190, 200 and 210 degrees C, giving different outlet values about yield and final moisture.
