SUMMARY Cheese is the oldest form of preserving milk nutrients having nutritional, economic and cultural importance. The objective of this study was to identify the best time of the year for production, and period, in months, for maturation of traditional colonial cheese, through analysis of water activity, weight loss and counts of lactic acid, mesophilic microorganisms—proteolytic and lipolytic. Records of temperature and relative humidity (RH) were maintained. A completely randomized experimental design was used in a double factorial scheme, considering production periods and maturation times. For all production periods evaluated, there was a significant reduction in the periods for water activity values. The counts of lactic acid bacteria ranged from 104 to 109 CFU/g. There was also stability in the number of colonies for lipolytic mesophilic microorganisms, until the third month of maturation. Low counts of proteolytic mesophiles were observed for the samples produced in May and June (5.70 and 5.53 log), respectively. The production period for the months of May and June corresponding to RH of 80% and average temperatures of 15°C were the most effective for production. Due to the presence of Listeria, it is recommended to respect the minimum time of 60 days of maturation for commercialization.

This paper evaluates the nutritional impact on growth, production and quality variables of gerbera crop when fertigated with treated domestic effluents. An experiment was carried out in greenhouse at the Embrapa Meio-Norte in Teresina, in the State of Piauí, Brazil, from July to October 2007. A completely randomized experimental design with five treatments and five replications was adopted. The treatments investigated were T1 - 100% of water and nutritional requirements of crop were met with chemical fertigation (N e K2 O); T2 - 25% volume of water through fertigation and 75% treated wastewater effluents (TWE); T3: 50% volume of water through fertigation and 50% TWE; T4: 75% volume of water with fertigation and 25% TWE; and T5 - 100% volume of water supplied through TWE. Leaf growth and plant development were favored by the application of 50% fertigation and 50% TWE (T3). As for commercial requirements, the best results for number of flowers were obtained with T4. However, concerning quality, T2 produced flowers in July and August with longer stems, but in the months of September and October, no treatment achieved this standard due to high temperature and low relative humidity of the air in the region.

ABSTRACT The objective of this work was to evaluate the physiological behavior at different times of the day and the level of dependence between physiological variables and meteorological elements in Aleurites fordii seedlings. The experiment was conducted in a greenhouse, using a completely randomized experimental design, in a uniform scheme composed of 10 evaluation times (from 8 am to 5 pm, with an interval of 1h between evaluations) and three replications. Each replicate consisted of three evaluation plants, totaling nine seedlings, which were arranged on a double border. The following characteristics were evaluated: leaf temperature (ºC), photosynthetically active solar radiation ((mol S-1 m-2), stomatal resistance (S cm-1), and transpiration (mmol H2O s-1 m-2) over a typical day, using a LI-1600 LI-COR digital porometer. The temperature and relative humidity were measured inside the greenhouse, using a thermohygrograph. The evaluations were performed at 244 days after sowing, between 8:00 and 17:00, with an interval of 60 minutes, totaling 10 evaluations. The physiological changes of Aleurites fordii seedlings are affected by the time of day. In general, the physiological variables are highly dependent on meteorological elements. The temperature of the greenhouse and the relative humidity are the meteorological elements that most influence the physiological behavior of Aleurites fordii seedlings.

The objective of this study was to evaluate the microbiological, physiological and qualitative changes in fresh cut yam (Dioscorea alata) stored at different temperatures. The experimental design was completely randomized in factorial scheme 4x4, with four storage temperatures (5, 10, 15 and 20ºC) and four evaluation periods (0, 3, 6 and 9 days after processing) with four replications. The microbiological analyzes were performed at 0, 3 and 9 days after processing. Fresh cut yam stored at 5ºC kept respiration rate, ethylene production at low levels similar to those found in yam not processed and stored at 20ºC. The weight loss, lightness and psicotrophic bacteria counting in fresh cut yam stored at 5ºC were kept within the trading patterns until the third day.

ABSTRACT: This study aimed to evaluate the effects of the quantity and soil position of Urochloa ruziziensis straw desiccated with glyphosate for different periods of time on ‘M-SOY 7908 RR’ soybean nodulation, growth and production characteristics. Three experiments were conducted under semi-controlled conditions. In the first, three quantities of U. ruziziensis straw (2.5, 5.0 and 10 ton ha-1) previously desiccated with glyphosate were incorporated into the soil (10 cm deep) or deposited on the soil surface, and in the second experiment, the treatments consisted of three U. ruziziensis desiccation periods, 0, 7 and 12 days before soybean sowing, and one treatment without U. ruziziensis. In the third treatment, desiccation was performed at 0, 5 and 10 days before soybean sowing, and the desiccated plant shoots were removed or left in place before soybean sowing. For each of the experiments, a completely randomized experimental design was adopted, and the masses of the shoot and root dry matter, the degree of nodulation and soybean production were evaluated. The deposition of U. ruziziensis straw on the soil surface promoted the nodulation and growth of ‘M-SOY 7908 RR’ soybean plant shoots, while its incorporation into the soil, even at 2.5 ton ha-1, caused deleterious effects. Desiccation of U. ruziziensis from 0 to 7 days before sowing was also detrimental to the nodulation and growth of M-SOY 7908 RR soybean, reducing its productivity.

This objectives of this research were both to study and determine the best level of concentration of yeast Saccharomyces cereviseae and period of fermentation on the quality of tomi-tomi vinegar (Flacourtia inermis). A completely randomized experimental design with two factors of treatment was applied in this research. The first factor was concentration of yeast S. cereviseae having four levels of tretament, i.e.: without the addition of yeast 0.5, 1 and 1.5 g yeast. The second factor was period fermentation with 1, 2, 3, 4, and 5 weeks. The result indicated that the concentration of yeast S. cereviseae 1.5 g and period fermentation 5 week produced a good tomi-tomi vinegar with total acids 51.22%, total dissolved solids 8.35, total sugar 8.07% and pH 5.40.

An adequate protein intake prevents the loss of fat-free mass during weight loss. Laparoscopic sleeve gastrectomy (SG) jeopardizes protein intake due to post-operative dietary restriction and intolerance to protein-rich foods. The purpose of this study is to evaluate protein intake in the first three months after SG. We evaluated, 1 month and 3 months after surgery, 47 consecutive patients treated with SG. Protein intake, both from foods and from protein supplementation, was assessed through a weekly dietary record. Patients consumed 30.0 ± 10.2 g of protein/day on average from foods in the first month, with a significant increase to 34.9 ± 4.8 g of protein/day in the third month (p = 0.003). The use of protein supplementation significantly increased total protein intake to 42.3 ± 15.9 g protein/day (p < 0.001) in the first month and to 39.6 ± 14.2 g of protein/day (p = 0.002) in the third one. Compliance with supplement consumption was 63.8% in the first month and only 21.3% in the third month. In conclusion, both one and three months after SG, protein intake from foods was not sufficient. The use of modular supplements seems to have a significant impact on protein intake, but nevertheless it remains lower than recommended.

Determining Factor

The present paper is the third of a series dealing with the effects of freezing and drying on living amphibian muscle (1, 2). In this paper it is shown that simple drying of muscles causes the production of lactic acid, in amount identical with that produced by the corresponding degree of freezing (2). This finding confirms the view expressed in the earlier communications that the effects of freezing and drying are identical, the determining factor in each case being the removal from the muscle of a certain amount of water. Experimental Procedure . To ensure even drying throughout, it was necessary to use a thin muscle of regular geometrical form. The sartorius muscle of the frog was therefore chosen. The frogs were precooled for some hours at zero. The muscles were then carefully removed at their insertions, wiped on filter paper, and each individual muscle suspended by a silk thread of known weight (see later) in a stoppered bottle, over 0·72 per cent, sodium chloride solution. After standing at 0° C. for 24 hours, to allow of the removal of the lactic acid formed during the manipulation, the muscles were weighed, and rapidly dried by being suspended in bottles over solid calcium chloride. It has already been shown that this method of drying produces a uniform state throughout the muscle (1, p. 187). They were removed at intervals for weighing.
