Fruit Coating with Chitosan and Beeswax to Increase Papaya Shelf Life

Papaya (Carica papaya) is a climacteric fruit with an increased respiration rate during ripening process. Papaya respiration rate can be inhibited by providing a coating on the surface of the fruits, including chitosan, a polysaccharide derived from shrimp shell waste, or beeswax.The purpose of this research was to examine the effects of chitosan and beeswax coating on the shelf life and quality of papaya Callina fruit during storage. Results of the experiments showed that fruit coating with chitosan and beeswax can extend the shelf life of papaya Callina by four to five days compared to control due to inhibition respiration rate of papaya fruits during storage.The use of chitosan and beeswax was beneficial to maintain the physical and chemical quality of papaya Callina fruits.

ABSTRACTBananas are commonly consumed because of their nutrition content and affordability. Banana fruits are rapidly over riped. Therefore, harvest time is key point for long shelf life. The aims of this study is to analyze the criteria of Raja Bulu Banana’s (Musa paradisiaca) ripeness in post-harvest with several picking dates and to determine the best picking date for favorable post harvest handling. This study was conducted from January until June 2014. Tagging was held in January at farmer located in Sumedang (900 m above sea level, West Java). The post-harverst evaluation was conducted from Mei until June at the Postharvest Laboratory, Departement of Agronomy and Horticulture, Faculty of Agriculture, Bogor Agricultural University. The experiment was arrangedin a randomized complete block design using single factor with 5 replications for 5 picking dates, i.e. 85, 90, 95, 100, 105 and 3 replications for 110 days after anthesis (DAA). This study showed that the best picking-time for Raja Bulu Banana was achieved in 85 DAA with 11 days of shelf-life and heat units 1305.5 0C day. The later the picking age was negatively correlated with the length of shelf life. The younger the picking age was negatively correlated with respiration rate. Picking date did not affect the physical and chemical quality of post-harvest fruit at the same maturity level.Keywords: color scale, respiration rate, shelf lifeABSTRAKPisang lebih disukai oleh masyarakat karena harganya yang terjangkau dan banyak mengandung vitamin dan mineral.

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.

The experiment was conducted to determine the effect of turmeric powder supplementation to the age of sexual maturity, physical, and chemical quality of the first Japanese quail’s (Coturnix japonica) egg. Forty five quails were assigned into a completely randomized design with three treatments (levels of turmeric powder, i.e., 0; 54; and 108 mg/quail/day) and each treatment used 15 quails. Turmeric powder supplementation was conducted before sexual maturity. Feed and drinking water provided ad libitum. Observed egg is an egg that was first produced. Parameters measured were the age of sexual maturity, feed intake, body weight, physical qualities which include: weight of egg, long axis, short axis, weight and thickness of shell, yolk index, Haugh unit, egg shell index. Whereas the observed chemical quality were cholesterol, HDL, LDL, protein, vitamin B12, vitamin A in eggs and egg shell calcium levels. The results showed that administration of turmeric powder can accelerate the age of maturity, increasing the levels of protein, HDL, vitamin A and B12 in eggs, decreasing the cholesterol and LDL content in eggs, but did not affect feed intake, physical quality of eggs and egg shell calcium levels. Based on the results of this study, it can be concluded that supplementation of turmeric powder improve the chemical quality of Japanese quail eggs (Coturnix japonica), so it is good for the development of quail embryos as well as for consumption.How to CiteSaraswati, T.
