STUDY OF USING PULSING AND PACKAGING ON ROSE CUT FLOWERS TO PROLONG VASE LIFE

Using pulsing on rose cut flowers before storage and transportation should be done to kept its quality after storage. The objective of the study is to find out the composition of the pulsing to prolong the vase life. The flowers were harvested from the field when the flower was at two bud opening stages and then were pulsed with chemical solution. The experimental design used RAL and data analyzed with Analisis of Variant (ANOVA). If found out significant between treatment then continued by Duncan test. The result indicated that pulsing 3% sucrose + 25% glyserin + 300 ppm Na-Benzoat + 375 ppm sitrat acid was the best composition and decrease deterioration about 2.5% until day-3 vase life. Each flower was placed in the boxes of 60 x 15 x 7 cm3 with capacity of 20 rose cut flowers. Package with the ventilation of 3.5 cm in diameter and closed with the film polipropilen was the best design package which prolonged vase life until 5 days after storage and decrease senescence up to 20-25 0/o.The periode of flowers vase life could be extended and quality after storage could be maintained by applying those treatment

STUDY OF PRESERVATIONDRY SWEET PINEAPPLE (Ananas comous L. Merr) DURING STORAGE

Processing fresh pineapple into dried sweet pineapple can preserve product during storage. Durability dry sweet products can be maximized by combining sugar with other preservation techniques such as paesterisasi treatment, enhance sodium benzoate, and packaging technology. The objective the study is to find out durability time product dry sweet pineapple. The study design used experiments making dried sweet pineapple which consists of several stages. There are stripping, washing, cutting, boiling, cooking, soaking, drying and packaging. Drying is done for 3 days under the sun. The durable time have known by observations during storage; dry sweet pineapple with packaging and stored without packaging. Product damage during observed indicated by physical appearance, color and texture. Durability dry sweet pineapple without packaging lower than product with packagin

Pengaruh Jenis Kemasan dan Tingkat Kematangan terhadap Kualitas Buah Jeruk Selama Penyimpanan

Packaging and maturity levels are considered to be two most important determinant factor that may affect of freshness the citrus duringstorage. The objective of the study to find out the best type of packaging and maturity levels to weights loss and damage of productduring storage. The experimental used randomized factorial design that the maturity levels as the first factor and type of packagingas the second factor and LSD analysis testing followed if there are significant differences among the treatment. The result indicatesthat type of package and the maturity levels affected of citrus quality during storage. The Packaging with the ventilated cardboard boxand plastic crate are the best packing in protecting for citrus fruit and than prolong it shelf life for 16 days of storage. The over maturityshowed the higher weight loss value than green maturity and the optimum maturity levels

ABSTRACT Pretreatment and packaging or rose cut flowers during stroage and transportation should be designed in order to keep its quality during vase life of the flowers. The objective of this study was to find out the pulsing solution and the design of packaging to prolong the vase life of the rose cut flowers. The flowers were harvested from Loji, Cipanas, when the flower was at two bud open stages. Before storage, the flowers were pulsed in the chemical solution of sucrose, glyserin, Na-benzoat and citric acid at different concentrations. Each 20  cuts of flower were placed in the boxes of 60 ´ 15 ´ 7 cm3with different ventilation system. The result showed that the pulsing solution with 3 % sucrose, 25% glyserin, 300 ppm Na-benzoat and 375 ppm citrit acid caused a signioficant decrease in the respiration rate and prolonged the vase life of the flowers. The  packaging model gave an effect of modified atmospheric environment inside the packaging and significantly affected the flower quality during stronge. The result suggested that the use of the packaging with the ventilation of 3.5 cm in diameter using polypropilene film would be suitable for rose cut flowers packaging during storage. The packaging model prolonged the vase lilfe of the flowers until 6 days after 5 days of storage and decreased the flowers senescene up to 20-25%.

The Variuous Packaging Effects of Loker Telun Berasap Chili Damage During Storage

General characteristics of fresh horticultural products like chili, is easily get damaged after harvest. The chili declining quality and loss after harvesting occur due to ongoing respiration process. Hence, the chilies become wither or rot. This damage happens due to physical, microbiological, and physiological influences. Physical damage and yield loss can be caused by packaging uses during storage. The study aimed to determine the effect of packaging use type for Locker Telun Berasap chillies on the weight loss and damage during storage. The treatments were the commonly community packaging use types which consists of: a) polyethylene plastic (PE), b) paper and c) banana leaf. Each treatment was performed two replications and stored at room temperature. Observation parameters during storage were weight loss, and physical, physiological, microbiological damages. The lowest weight loss percentage for 12 days’ storage by PE packaging was 45.5%. The total damage was 30% lower compared to paper and banana leaf packaging. Optimal freshness can be achieved until the 8th day of storage with physical damage only 1.03% on PE packaging. The results of the study showed that the dominant microbiological damage was found in the banana leaf packaging treatment
