Abstract

A fresh is perishable mainly due its high respiration rate. This research was conducted to examine the use of gelatine and citric acid in the glycerol containing edible coating to reduce the rate of deterioration of tomatoes during storage at room temperature. The use of edible coating is expected to be able to substitute a low temperature storage which is more expensive. The respective concentrations evaluated were 10%, 12% and 14% for gelatine and 0,5%, 0,7% and 0,9% for citric acid. The experiment was run in triplicates employing a factorial completely Randomized Block Design using a breaker ripe stadium tomatoes of Intan variety grown in Malang regions. The treated tomatoes were stored at room temperature until a red ripe stadium was achieved. The results indicated that all the 9 treated samples were able to reach a red ripe stadium with some variations of quality after 15 days of storage. In general, the treated samples show a higher rate of respiration and higher level of vitamin C, but were firmer in texture and a lower level of weight lost than the ones of control. It was found that the use of 14% (w/v) gelatine and 0,9% (w/v) citric acid in a combination with 5% glycerol is the most effective to use as an edible coating for tomatoes stored at room temperature (26-29oC). The lost of the above-mentioned quality attributes is still minim after 15 days storage.   Key Words: Tomatoes, Edible coating, Respiration

Abstract

The research was conducted to compare antioxidant and antibacterial activities of some products derived from a typical fruit, locally known as Mahkota Dewa fruit (Phaleria macrocarpa (Scheff) Boerl). These products consist of: a dried fruit, an instant powder (produced by high temperature processing technique) and effervescent powder (produced by low temperature processing technique). The antioxidant activity was monitored within 8 days incubation, and the activity was determined after 24 hours of incubation against two respective bacteria, namely Staphylococcus aureus and Eschericia coli at various concentrations i.e.: 12.5%; 25% and 50%  respectively. The results showed that the three products contain high levels of antioxidant, but were less stable than that of the synthetic one. The highest antioxidant activity of all product was identified on the 4th day of incubation: 48,71% (an effervescent powder); 37,88% for the dried fruit and 33,27% for instant powder) the antioxidant activity of fruit and fruit product dropped significantly after 4 days of incubation. The products were more effective against E. coli than S. aureus and the activity increases with concentration.   Key Words: Mahkota Dewa, Antioksidant activity

Abstract

This research was intended to use IPPS model for estimating industrial pollution load in Surabaya.  Descriptive-analytic method was chosen as the research methodology and consists of two main stages, i.e. classify industries base on the ISIC code and estimate pollution load of each industrial sector based on the number of employments’ variables.  Major data used are the annual industrial activities provided by BPS.  The data includes the name, addresses, main product and number of employees of the industries. The estimation has been carried out on six types of air pollutant, namely levels of SO2, NO2, VOC, CO, TSP, PM10 and two types of water pollutant (TSS and BOD). The result shows that the Chemical Producer N.E.C Industries are main contributor for the pollutant of SO2, NO2, and VOC, while TSP and PM10 are given mostly emitted by Oil and Fat Industries. On the other hand, the Soap, Cleaning Prep, Perfumery and Toilet Prep Industries are the main contributor for CO.  The BOD pollution load comes mainly from Pulp, Paper and Paperboard Industries and the TSS is contributed primarily by Iron and Steel Mills, Foundries, and Re-Rolling Industries.   Key Words: industrial pollution, pollution load

Abstract

The aim of the research on processing of tomato powder (Licopersicon esculentum Mill.) by means of ”foam-mat drying” were to investigate the effect of foaming agents on physical-chemical characteristics of tomato powder. Egg white (0; 2; 5 % b/b) combined with Tween 80 ( 0; 0,2; 0,5 % b/b) was used as the foaming agents. The results showed that the increase of egg white concentration very significantly increased the levels of vitamin C, pH, yield and water vapor reabsorbs ion, but reduced   the titratable acidity. Whereas the increase of Tween 80 concentration very significantly  increased the vitamin C content, water vapor re-absorbsion  and the dispersion stability. The tomato powder with best characteristics was produced by the use of egg white only (2%) as the foaming agent. The yield obtained was 17.8% and contained 2.22% moisture, 68.05% total sugar, 5.50% titratable acidity, pH 3.75 and vitamin C of 77,77 mg. 10-2 g-1. The respective water vapour reabsorbsion and dispersion stability of the product were 2.72% and 83.22%.   Key words: tomato powder, foam-mat drying,  foaming agent
