Pigment Extract

Red roses  (Rosa sp)  are a  decorative plant species.  Their petals contain the pigment anthocyanin, which is classified as a flavonoid and is able to capture free radicals.  Due to their popularity, roses are an abundant resource and can be processed into effervescent drink tablets. This study aims to investigate the influence of time after harvest and filler type on the quality of the red rose extract powder, on effervescent tablets made from the said extract and on effervescent drink quality. The study was conducted in two stages. Phase I tested the quality of pigment extract of hybrid varieties of Dutch roses.  Three post-harvest durations were tested using a Randomized Block Design: fresh, or 0 days after harvesting (U0), 2 days after harvesting (U1) and 4 days after harvesting (U2). Phase II used a Randomized Block Design arranged in factorial to test rose extracts taken from flowers at 3 post-harvest durations (U0, U1, U2) in combination with 3 different filler types [NaHCO3 (N0), KHCO3 (N1), CaCO3 (N2)]. Resulting pigment extracts were analyzed for water quality, pigment quality, pH, and colour intensity.  Effervescent tablets made from the various pigment extracts were also measured for water quality,  sugar level,  pH, moisture content, tablet density, and colour intensity. Study findings revealed that time after harvest affected pigment extract pH, absorbance, light (L), and red (a+)/yellow (b+) colour intensity, while water content and soluble solid content and quantity were unaffected. Analysis of effervescent tablets found that time after harvest, was linked to differences in water content, texture,  light intensity (L) and red  (a+)/yellow (b+) intensity while there was no effect on moisture level.   Analysis of effervescent tablet drinks found that harvest time and filler type affected pH, dissolution speed, colour intensity and flavour. However, neither time after cutting nor filler type had a significant effect on the quantity of soluble solid, colour, appearance or taste of the drinks.

Abstract For the production and quality of pineapple fruits, the appropriate choice of the type of propagule to be used combined with the management of the ages for floral induction are important factors to reach the maximum of desirable characteristics that will define the success in the production of the pineapple and its good acceptance in the market. The objective of this research was to evaluate the post-harvest quality of fruits developed from different types of shoots and ages of floral induction of ‘Vitória’ pineapple. The experiment was carried out in a complete randomized block design with four replications. The plots were made up of the shoots (slip and sucker) and the subplots were composed of the different ages of floral induction (8, 10 and 12 months after planting and natural flowering). Evaluations of biomass characteristics of fruits with and without crown, circumference, length, diameter, firmness, translucency, pulp color and physicochemical quality were performed. No significant interaction was observed for the biometric and biomass variables, and the type of shoots influenced only the crown biomass and the central cylinder diameter, which were higher in the slips. In addition, for the attributes color, translucent area and firmness, no interaction was found, and they were influenced only by the induction times, except for the variable color referring to the intensity of green and red colors. Regardless of the types of the shootss evaluated in the environmental conditions of planting carried out in April 2015, the fruits originated from natural inductions and inductions at 12 months presented greater firmness, a desirable characteristic for export and industrialization, mainly for the processing of slices of pineapple, pieces in syrup and crystallized. The slips natural induced and induced at 12 months provided fruits with a greater ratio between soluble solids and acidity.

Fertilization outside the season of Siam Orange (Citrus microcarpa L.) with Induction of Flowering and Dormancy Breaking Substances. The Siam orange (Citrus microcarpa L.) produces seasonal fruit with the on-season harvest from July to August while the off-season harvest, i.e. from February to September there is hardly any fruit, or very limited supply. The purpose of this study was to examine the response of flowering induction and dormancy-breaking substances to produce off-season fruits of Siam orange. This research began in April to December 2016. The experiment was arranged factorially with two factors using a randomized block design (RBD), with nine combination treatments and six replications. Flowering induction factors consist of three levels, namely Ik = Control, IP = Paclobutrazol at a dose of 7.5 g/l, and Im = cutting the tip of dormant twigs. Dormancy-breaking substances factor consists of three levels, namely Dk = Control, Db = BAP 200 ppm, and Dn = KNO3 300 ppm. The results of the experiment showed that the highest fruit weight per tree at off-season production was obtained by induction with paklobutrazol (28.86 kg) and the lowest was in control (12.75 kg). Flowering induction treatments was not significantly different effect on fruit quality of Siam orange, represented by weight per fruits, fruit diemater, total soluble solid and vitamine C content was not siginificant different among levels of treatment. Dormancy-breaking substances treatment also not significantly effect on fruit quality of Siam orange. Based on this research it is recommended to induce flower for off-season produce of Siam orange by pruning the tips of dormant twigs or by using paklobutrzol.

ABSTRACT Tomatoes are an important component of the human diet because they are rich in minerals and antioxidants that sequester free radicals in cells, preventing various disorders that affect human health. Here, we aimed to evaluate the effects of different nitrogen sources and concentrations on antioxidant capacity and physical and chemical quality of tomato fruit. The experiment was conducted in Vitória da Conquista, state of Bahia, Brazil, in the experimental field of Universidade Estadual do Sudoeste da Bahia. The experimental setup included a randomized block design with four replicates in a factorial layout of 3 × 3 + 1 (control), for a total of 40 plots. The three treatments comprised different nitrogen sources (calcium nitrate, urea, and ammonium sulfate), applied in three doses (140, 280, and 420 kg ha-1). We evaluated firmness, pH, titratable acidity - TA, soluble solid - SS, SS/TA ratio, ascorbic acid, carotenoids, flavonoids, phenolic compounds and DPPH inhibition, were evaluated after samples were harvested. However, increasing concentrations of N adversely affected the acidity and led to an increase in the SS/TA ratio. Increasing the N concentration also reduced the content of bioactive compounds. excluding carotenoids, which consequently impaired antioxidant activity.

Slaughtering is a method used to obtain food from farmed animals. Chicken slaughter is one of important factors affevting the halal and nutritional quality of meat. Chicken meat slaughtered is done according to islamic sharia and not according to Islamic sharia. Slaughtering is carried out according to islamic or halal sharia according LPPOM-MUI (2008). The storage time for food is a period of time that is safe and suitable for consumption in food and can be used by consumers according to their needs and can maintain the state of the food that is packed. Determine the quality of chicken meat whether or not accepted by consumers affect the physical, chemical and biological quality. The study aims to determine the effect of slaughtering methoda (according to Islamic sharia and not according to Islamic sharia) and duration of storage on the quality of chicken meat. This research uses factorial randomized block design (RBD) consisting of 2 factors. The first factor is the method of slaughtering, namely slaughtering by Islamic sharia and slaughtering not by Islamic sharia (neck slaughter broken). Slaughtering by Islamic sharia is chicken slaughtering in RPA that is halal certified, while slaughtering is not by Islamic sharia is chicken slaughtered in RPA that is certified not halal. The second factor is storage time, which is 0 hours (control), 3 hours, 6 hours and 9 hours. The result of this study showed that slaughter had a very significantly affected (P 0,01) on skin color. The treatmment duration significantly affected (P 0,05) on water content and suppleness. Research shows that the quality of chicken meat slaughtered according to Islamic sharia (P1) is better than meat slaughtered not according to Islamic sharia, especially in terms of; as higher skin color. As storage time increases, the water content
