The aims of this study were to evaluate the physical and chemical change of pummelo fruit during storage with waxing and wrapping, and to determine the effect of waxing and wrapping and their  its interaction in affecting shelf life of pummelo fruits. This research was arranged in a randomized complete block design with two factors and three replications. The first factor was waxing consisted of without waxing, 10% beeswax, 5% beeswax, and chitosan. The second factor was wrapping consisted of without wrapping and wrapping using either transparent yellow or white plastic wrap. Pummelo fruits experience weight loss, reduced total soluble solid (TSS), decrease in firmness and total acidity during 48 days of storage in room temperature. Waxing using beeswax or wrapping using plastic wraps significantly suppressed weight loss and maintained fruit firmness compared to those without waxing and wrapping. However, waxing and wrapping did not significantly affect the quality of pummelo fruits. Based on the fruit’s weight loss, firmness, and panelist preferences, 5% or 10% bees wax can be used as waxing. Both transparent yellow and white plastic wraps can be used to maintain fruit weight, firmness, and appearances during storage.

The utilization of brewery waste in ration to improved the quality of lamb meatABSTRACT. An experiment has been conducted to study the utilization of brewery waste in ration to improved the meat quality of lamb. High quality of lamb meat can be reached by manipulation of rumen fermentation. Tannins in brewery waste can decrease the activity of rumen microorganism and inhibite the rumen biohydrogenation processes. The experiment was conducted with an experimental method by in vivo technique, using 16 heads of local lamb, 4-5 months old, with body weight range of 5-10 kg.  The trial was conducted for 150 days, using Completely Randomized Block Design with 4 replicates. The treatment tested were 4 levels of Brewery Waste : R1 = 12%; R2 = 24%; R3 = 36% and R4 = 48%. The variables measured were : physical and chemical quality of meat. The result indicated, that the treatment tested significantly affect the meat quality physically, except to the percentage of edible distal meat and proximal bone weight.Based on the all variables measured, the research conclusion : (1) the utilization of brewery waste up to 48% dry matter  ration, could be used, without any physiology and metabolism disturbance; (2) the highest increasing of unsaturated fatty acid was stearic acid (C18:0) as much as 54. 60%, was reach by R3 (36% brewery waste); the linoleic acid increased as much as 43.91% reach by R4 (48% brewery waste);  the oleic acid increased as much as 37.48% by R2 ( 24% brewery waste). From the result can be suggested that the need of tannin brewery waste as biohydrogenation inhibitor would be more effective and efficient whenever brewery waste usage has been increased up to 60% dry matter ration.

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.

Three commercial sugarcane varieties such as NCO-334, B52-298 and N14 were grown at Finchaa Cane Plantation, Ethiopia to determine the optimum harvest age for cane and sugar yields. Treatments consisted of factorial combination of varieties and five levels of harvest age were arranged in Randomized Complete Block Design with three replications. The varieties differed in stalk diameter and weight, and millable stalk number. Improvements in internodes number, stalk diameter and weight were increased with harvest age whereas internodes length and millable stalk number decreased with delay in harvesting. Varieties produced better juice quality in canes harvested at 17 months. NCO-334 attained its peak superior quality at the age of 15 months. This preliminary data on some indicator quality parameters imply that NCO-334 could be harvested at 15 months age in order to maximize sugar yield. However, more experiments are required to confirm the effect of harvesting time and variety on cane and sugar yield. Therefore, more research on detecting other quality parameters focusing on cane and sugar yield is recommended.

The method for determining the appropriate time to harvest banana could affect the shelf life and quality of banana fruits during storage. The objectives of this study were to establish the heat unit as harvesting criteria of banana “Mas Kirana” and to evaluate how heat unit affects fruit shelf life and postharvest maturity characteristics. The research was conducted at PTPN VIII Parakansalak Plantation, Sukabumi, West Java, Indonesia, in November 2017 to February 2018. Laboratory analysis was conducted in Postharvest Laboratory, Department of Agronomy and Horticulture IPB in February to April 2018. The experiment was organized in a completely randomized design with a single factor of eight different flower tagging times after anthesis. Each treatment was replicated five times totaling 40 experimental units. The results showed that the different times of anthesis did not affect fruit size, weight per hand, number of fruits per hand and weight per fruit. Different time of anthesis did not affect respiration rate, fruit shelf life, physical and chemical quality. The minimum heat unit of 650ºC degree days can be used as harvesting criteria for banana “Mas Kirana”. The number of day after anthesis was 39 to 43 with fruit shelf life of 12 to 16 days.

ABSTRACT: The aim of this research was to evaluate the effect of preharvest boron application on the physical and chemical quality of 'Galaxy' apples after harvest and in controlled atmosphere storage during eight months, plus seven days of shelf life at 20°C. The experiment was performed with two treatments applied on the field: [1] Control (fruit without boron application) and [2] Foliar application of boron (four applications of 1.5kg ha-1). Findings showed that the boron application promoted a higher ethylene production and respiratory rate and it application also reduced the flesh firmness in relation to the fruits without it. A similar result was obtained after eight months of storage plus seven days of shelf life. The preharvest application of boron makes it possible to harvest apples earlier due to the fact that it accelerates the fruit metabolism. However, the fruits end up presenting a lower storage potential as a result of the higher ethylene production, respiration rate, decay incidence, mealiness and a reduction of the healthy fruit percentage and flesh firmness after CA storage.
