Dietary Adequacy in Older Adult Nursing Home Residents of the Northern Iberian Peninsula.

According to the latest data, Spain (19.4%) and Portugal (21.8%) are the two European countries with the highest percentage of older adults.

Evaluation of a modified atmosphere packaging system in pallets to extend the shelf-life of the stored tomato at cooling temperature.

A modified atmosphere packaging (MAP) system in pallets was developed and its effect on physico-chemical and sensory characteristics and shelf-life of tomato was evaluated. Tomatoes were stored at 6 °C in cardboard boxes arranged on pallets wrapped in micro-perforated low-density polyethylene (LDPE) bags. Effects of the storage time and packaging were evaluated after 0, 7, 14, and 21 days of storage.

Sensory evaluation of low-fat yoghurt produced with microbial transglutaminase and comparison with physicochemical evaluation.

Background: Low-fat or non-fat yoghurts are popular nowadays. However, their texture is not good and they show considerable syneresis with time. The aim of this research was to evaluate the effect of the application of transglutaminase (TG) to low-fat yoghurt to determine if similar sensory properties to those of full-fat yoghurt can be obtained.

Physicochemical evaluation of low-fat yoghurt produced with microbial transglutaminase.

Background: Currently consumers demand low-fat or non-fat yoghurt but their physical properties are less attractive than those of full-fat yoghurt. It was reported that microbial transglutaminase (TG) can be used in the production of low-fat yoghurt. The aim of this work was to evaluate the effect of TG on low-fat yoghurt to improve their physicochemical and textural properties to approach to those of full-fat yoghurt.

Development and validation of an HPLC method for the determination of thiamine and riboflavin in green leafy vegetables using clara-diastase.

There is no literature on the use of the currently available form of clara-diastase (≥ 35 U/mg; Fluka Product No. 86959) in the analysis of vitamins B(1) and B(2) . Consequently, a method for the determination of total riboflavin and total thiamine in green leafy vegetables by high-pressure liquid chromatography (HPLC) following sample preparation by sequential acid hydrolysis, enzymatic hydrolysis with clara-diastase ≥ 35 U/mg, and for B1, derivatization to thiochrome, was developed and validated.

Use of physical and chemical properties of commercial tomato (Lycopersicon esculentum Mill.) products for monitoring their quality.

Eighteen physical and chemical variables were determined in 25 samples of commercial tomato products: total solids, soluble solids, water activity, lycopene, 5-hydroxymethyl-2-furfural, CIE(L*a*b*) components (L*, a*, b*, a*/b*, C*, H degrees), total acidity, sodium chloride, wet-weight pulp percentage, alcohol insoluble solids, total pectic substances, ascorbic acid, and pH. In order to maximize the variability of products, samples included crushed tomato, tomato puree, tomato paste, and heavy concentrates and were taken from Italy, France, Spain, Portugal, the United States, Mexico, Colombia, and Chile. Correlation analysis and multidimensional data analysis techniques (principal component analysis and hierarchical classifications) were used to describe the products' variability and to study the relationships among variables.
