ABSTRACT
The aim of this reaserch were to study changes of texture of Zalacca fruits from consequence of modified atmosphere packaging and to study of respiration rate of Zalacca fruit to preserve at modified atmosphere packaging.
The treatment of this reasearch was packaging with polyethyline plastic package or passive atmosphere with thickness 0.02 mm and perforation diameter hole is 0.6 cm. The various perforation is 0, 4, 8 and 12 hole. The storage time was set at 0, 2, 4, 6, 8, 10, 12 day in room temperature.
The result showed that the changes of texture of Zalacca fruit was increased during the storage time. The changes of texture rate was slowly at 8 hole polyethyline plastic perforation packaging. At the begining of the storage time, the respiration rate have been increased while in the midle have been decreased. Finally, at the end, the storage time have been increased. The respiration rate was slowly at 8 and 12 hole polyethyline plastic perforation packaging.

Zalacca Fruit
INTRODUCTION
There is inclination that consumer be apt to food product which are fresh, practical and high quality (Daugherty, 1990; Labuza and Breene, 1989; Myers, 1989). In last decade in the U.S.A., it was noted that consumption of fresh food product increase in 12%, frozen food product increase by 10%, but canning food product decrease by 10%. Therefore, Indonesia has good opportunity of exporting fruits and vegetables. In order to increase the export value of agro-industry, fruits and vegetables should be cared and handled very well.
peeled off, and bruised. Microbe damage is caused by infection and microbe activity. Physiological damage occurs due to internal metabolism reaction resulting in putrefaction.
Zalacca (Salacca edulis, Reinw) is Indonesia native fruit. Production was high, reaching 662,546 tons in 1995 (Anon, 1995 in Agung et. al., 1999). The cultivation areas of zalacca in Indonesia are Bandung (Batujajar), Tasikmalaya (Manonjaya), Jogjakarta (Sleman), Malang, North Sumatera, South Sulawesi, Central Java (Ambarawa and Magelang) and Bali.
The increasing production and fulfillment of demand should be balanced with post harvest treatment. This should be considered becausezalacca as other fruits is easy to get damage. The negative environment factors along the storage cause of fast decreasing quality resulting in short storage time.
In order to increase the storage time and to avoid damage, delaying the mature is performed by decreasing oxygen absorption and release of CO2 of zalacca. This can be done with atmosphere modification.
Low oxygen and high CO2 in modified atmosphere give influence in decreasing respiration rate, ethylene
production rate, retard the maturation and others relate to mature such as soften of fruit, change of color, lose of sugar and retard the putrefaction (Brecht, 1980; Kader, 1980).
An appropriate post-harvest treatment of zalaccamay give result in added value of long storage time which means more profit for the farmer, seller and other parties.
AIMS
The aims of the research are
a. Studying changes of texture of fruit as result of storage in modified atmosphere.
b. Studying respiration speed of zalacca which are stored in modified atmosphere as function of O2.
METHODS
The research steps are preparation, respiration speed quantification, changes of the texture of fruit as result of storage in modified atmosphere, descriptive and graphical analyze.
A. Treatments
The treatments are polyethylene plastic cover with thickness of 0.6 cm (positive modified atmosphere) and storage time. The perforation of polyethylene plastic cover are 0 hole (without perforation), 4 holes, 12 holes and the storage time are 0, 2, 4, 6, 8, 10, 12 days. The samples treatment and one which is uncovered and used as the control group are stored in room temperature.
B. Respiration rates a. In tight close container
Close system is used in this experiment (Hangar et al., 1992 and Lee, 1997 in Song et al., 1992). Three samples are put in glass container/jarwith volume of 2.126 liters. Glass container is closed tightly (with glue/paint/vaseline to avoid leak).
In the middle of the lid, a hole cover with rubber is set to take the gas sample. This container is put in room temperature. Gas samples are collected every 2 days in 12 days. O2 and CO2 concentration are
detected with cosmotector. Type XP-314 cosmotector is used for O2 and XP318 for CO2. The relieved
b. In polyethylene plastic
Three samples are put in a sealed 6.80 liters volume of polyethylene plastic. A hole cover with rubber is set in the bottom part of the polyethylene plastic to make easy for taking the gas sample. The edge of the hole is sealed with glue/paint/vaseline to avoid leak. And then is put in room temperature. Gas samples are collected every 2 days in 12 days. O2 and CO2 concentration are detected with cosmotector. Type XP-314
cosmotector is used for O2 and XP318 for CO2. The relieved volume in the container is also counted. These
treatments are repeated for three times.
c. Change of Texture
The probe with diameter of 0.52 mm of FT 327 model of Hand Penetrometer Effegi is used to test physically the stringent of Bali’s zalacca to get data of texture of Bali’s zalacca. A small area of skin of sample was peeled and then holds by one hand while the other hand pushed the sample with Hand Penetrometer Effegi. The number in kg/cm2 read from the tool shows the texture value of the fruit. The test was repeated for four times for each sample and it was done for some samples. The values were then calculated for the average number.
RESULT AND DISCUSSION
1. Changes of Texture
Texture is a decisive factor of fresh fruits. Changes of texture of Bali’s zalacca showed that there was a variation of texture of Bali’s zalacca in storage. The graph of texture changes can be seen in Figure 1.
Fig 1. The changes of texture of Bali zalacca fruits during the storage time
Figure 1 showed that the changes of texture level of control of Bali’s zalacca and all the Bali’s zalacca treated with different perforation of polyethylene plastic container decrease during the storage. The decrease intextureis caused by saturated decomposing propectin to pectin enzyme activity. The solid state rate is caused by the change of cell size and turgor. The reason of texture become lossis related with high level of respiration activity and transpiration of the fruit causing loss of liquid. Therefore, cell size and pressure of inside cell to the cell wall decrease (Suter, 1988).

2. Respiration Rate
The data of O2 respiration rate of Bali’s zalacca in storage is presented in Figure 2. Figure 2 showed
that in every treatment, respiration rate of O2 changed rapidly, then were going slowly, and finally in a
certain time changed rapidly until the last period of storage.
Figure 2shows that O2 respiration rates were increase in the beginning of storage, then decrease, and
increase again till the last period of storage. Decrease of respiration rate is caused by a decrease in the substrate for respiration. As addition, the O2 in the container is used by the fruits for respiration and
substrate oxidation. With limitation of O2 in the container causing the delay of chlorophyll degradation, low
production of C2H4, decrease in production rate of ascorbic acid, change in composition of unsaturated fat
and degradation of pectin were not fast as in nature. These things were reflected as the delay of mature of fruit and, therefore, storage capacity of the fruit is long (Amiarsi et al., 1996).
Fig 2. O2 Respiration rate of Balizalacca fruits during the storage time
CONCLUSION
The weight of Balizalacca fruit was decreased during the storage time.
At the beginning of storage time, the result showed that the respiration rate of O2 have been increased while in the middle have been decreased.
We can use the polyethylene plastic packaging at perforation with 12 holes in modified atmosphere.
