The objective of this work was to evaluate the quality of the Ripa enriched with urea, yeast and sugar cane molasses, fermented and subjected to the drying process. Using as parameters: moisture content, Brix, pH, acidity and protein content. We used a completely randomized design with ten replications, two treatments and one control. The model included non-fermented (RNFM) and fermented (RFM) treatments of the variety of Rosinha cassava. Fermentation was performed during 132 hours under ambient conditions, with a 10% yeast treatment (w/V), 4% Urea (w/V) and 20% molasses (w/V) and the other 70 ml of distilled water. Regarding the moisture content of the material after the dehydration period, mean values between 46.42% and 58.33% were observed. The Brix degree of the water treatment and the control samples did not differ, however, differed from the treatment urea + molasses + yeast, which presented the highest values of this parameter. The pH averages ranged from 4.49 to 7.85, differing statistically. Titratable acidity ranged from 1.760 to 14.040. A considerable gain of crude protein was observed in the treatment urea + molasses + yeast, which was statistically higher than the others.

The objective of the study was to determine the chimical composition of phasey bean throughout the productive cycle. The experiment was carried out in the municipality of Capão do Leão – RS, physiographic south coast region of Rio Grande do Sul. At 45 days after the emergence of the plants, the first cut of the forage evaluation was performed and, at intervals of 15 days, another nine cuts were made, all 5 cm from the soil. The treatments corresponded to different evaluation dates of Macroptilium in free growth in an experiment with ten treatments and three replicates in a completely randomized design. The variables studied were neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL), crude protein (PB), total lipids (TL), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg). The results were submitted to analysis of variance and polynomial regression. All variables presented significance (P≤0.05) for cubic regressions, with mean values of: NDF = 58.15; FDA = 38.94; ADL = 9.15; PB = 11.59; TL = 1.18% e; P = 2.29; K = 10.19; Ca = 26.48 and Mg = 4.53 g / kg DM; similar to other hot-legged forage legumes. The bromatological quality of the Macroptilium lathyroides varied during the productive cycle, being directly influenced by the habit of indeterminate growth of the species. From the bromatological quality, the forage of the first growth of the Macroptilium lathyroides should be harvested up to 75 days after emergence, when the lower fiber and lignin contents associated with higher levels of crude protein, lipids, magnesium, and calcium.

Silicon (Si) is a mineral element that provides many benefits to plants and may also assist in tolerance to abiotic stresses such as salinity. The aim of the study was to evaluate the use of Si as a possible attenuator of the deleterious effects of salinity on growth and post-harvest of lettuce. A completely randomized design with four replicates was performed in a 3 × 2 factorial, consisting of three salinity levels (1.65, 3.65, 7.65 dS m-1) and two levels of silicon (0.0 and 2.0 mM). Salinity reduced all variables related to plant growth. For shoot fresh and dry mass, it was observed that NaCl caused a reduction of 79.80 and 80%, respectively, in comparison to the control. However, parameters related to post-harvest such as titratable acidity, soluble solids and vitamin C increased with salinity. Although not effective in reducing saline stress on plant growth, Si provided improvements in the variables related to lettuce post-harvest. Salinity significantly reduced plant growth in the presence and absence of Si, but provided better post-harvest quality with Si.

The main objective of the study was to standardize enrichment of aonla pulp to develop fruit bars. The experiment was laid out in Completely Randomized Design (CRD) with 10 treatments. Aonla pulp was blended with 25 to 75% of different fruit (mango, papaya and jackfruit) pulp viz. Aonla pulp, Aonla with mango, papaya and jackfruit in different proportion of 3:1, 1:1 and 1:3 each fruit respectively. The initial moisture content was higher in aonlapulp enriched with mango pulp in 1:3 proportions. Enrichment of aonlapulp with fruit pulp of mango, papaya and jackfruit reduced the ascorbic acid, titratable acidity and tannin content of the resultant fruit bars compared to that from pure aonla pulp, which is an indication in the reduction of astringency. Enrichment also resulted in an increase in total soluble solids, reducing, non-reducing and total sugars of the resultant fruit bars. Enrichment of aonla pulp with fruit pulp of provitamin A rich fruits like mango, papaya and jackfruit showed a rise in total carote-noids and reduced astringency and acidity, thereby resulting in fruit bars with altered palatability and enhanced nutrition. Enriched fruit bars contained three vital antioxidants viz. Vitamin C, carotenoids and polyphenols of all the treatments, enriched fruit bar containing 25 % aonlaand 75 % mango (T4) was found superior in organoleptic evaluation.

Microbial Dasyatis sp. (stingray fish) was a popular fish in Indonesia. Commonly, this fish is processed into smoked fish and perishable products. Therefore, it needs a preservation method through the handling process. Wet salting was considered as an efficient and inexpensive preservation method. This study aimed to determine the effect of brine concentration on the physicochemical and microbial quality of Dasyatis sp. The research used a Completely Randomized Design with factor of brine concentration (i.e. 10%, 20% and 30%). The statistical analysis consists of variance analysis (ANOVA) and followed by LSD or DMRT test (α=5%). The fish sample was soaked in brine solution at different concentrations for one hour. Total crude protein, physicochemical (total volatile basic nitrogen/TVB-N, tri-methyl amine/TMA, and pH), and (total plate count/TPC) were analyzed. The results showed that the brine concentration effect of physicochemical and microbiological of Dasyatis sp (p<0.05). The best treatment was obtained at the application of 10% brine concentration, which had physicochemical parameters as follows: 6.92 pH, 6.110 mgN/100g TVB-N, 5.520 mgN/100g TMA, 16.78 % protein, and 0.537x105 CFU/ml TPC.

The aim of this paper is to evaluate the forage utilization of winter catch crop in relation to yield and mixture composition. In 2006–2009, the plot experiment with winter pea in mixtures with rye and triticale was conducted under completely randomized design with four replicates. The productivity of mixture was above 10 t.ha−1 whilst the significantly lowest value was observed for pea monoculture. The rye represented the most productive component in mixture but it achieved lower forage quality in comparison with triticale. The ratio of pea varied from 7 to 38 % in dependence on year and companion cereal. The triticale mixture provided higher ratio in comparison with rye and significant differences between rye varieties were also detected. The quality of mixture was depended mainly on ratio of crops in the mixture. The ratio of pea significantly increased crude protein content in mixture according to linear regression where crude protein = 9.56 + 0.11* weight percentage pea ratio (P < 0.000, R2 = 0.89). Quality of pea forage was also influenced by companion crop where pea in mixture with rye achieved significantly lower quality. The amount of weeds was highest in the pea monoculture and lowest in mixture with rye.

The objective of this work was to evaluate the visual and chemical quality of tangerines after mechanical damage by impacts. The tangerine cultivars Montenegrina and Rainha were submitted to different degrees of impact and evaluated for decay and oleocellosis, loss of fresh weight, total soluble solids, total titratable acidity and ascorbic acid degradation, as well as for epicarp color changes. Experiments with three replicates and experimental units of six fruit for each cultivar were done in a completely randomized design. Impact produced qualitative internal and minor external changes on tangerines. The main modifications produced by impact on the fruit were losses of citric acid and soluble solids, which increased the solid:acid ratio, and losses of ascorbic acid. 'Montenegrina' tangerines are more susceptible to internal quality damage than 'Rainha'.

Lippia gracilis, popularly known in Brazil as ‘alecrim-de-tabuleiro’, is used for many purposes, especially as antimicrobial and antiseptic. The drying process of aromatic and medicinal plants aims to minimize the loss of active principles and slow their deterioration, which may greatly influence the yield and chemical composition of some species. The objective of this study was to evaluate the effect of drying times (0, 2, 4, and 8 days) on the content and chemical composition of the essential oil of L. gracilis accessions LGRA-106, LGRA-109, and LGRA-201. The leaves were dried at 40 oC, and essential oil was extracted by hydrodistillation. Chemical analysis was performed by GC/MS. The experiment was carried out in a completely randomized design with three replications. The accessions of L. gracilis LGRA-106, LGRA-109, and LGRA-201 presented higher essential oil at four days of drying time. The accession LGRA-201 showed the highest essential oil yields at four and eight days of drying, with mean values of 0.038 and 0.029 mL g-1, respectively. The drying time did not influence the contents of thymol, methyl-thymol, γ-terpinene, and carvacrol in the essential oils of L. gracilis, but affected the contents of β-caryophyllene, p-cymene, and carvacrol acetate. The essential oils of the three accessions analyzed in this study revealed different chemical profiles.
