Abstract

The primary cause of wilting in leafy vegetables after harvesting is high intensity of transpiration processthrough natural openings (stomata, hidatoda and lenticels). The mechanism of closing and opening of those naturalopenings is affected by the temperature of the environment. Under high external temperature, the stomata tendto open and vice versa. It is possible to diffuse water into the produce to give a vigorous effect by controlling theexternal temperature and moisture. The process is normally called crisping. The aim of this experiment was tostudy the effectiveness of crisping in order to give vigorous and freshness effects to four different leafy vegetables,namely lettuce, kangkung, leeks and chinese cabbage compared to those without crisping. The crisping processwas involving the immersion of produce in three different water temperatures (30, 40 and 50oC) combined withdifferent lengths of immersion times (1, 3, 5 and 7 minutes) and continued by immediate movement of produce tolow temperature (5±2oC) and stored for 12 hrs before placing and displaying at the show case under temperatureof 10±2oC. Produce treated as controls were provided without immersion in the warm water and stored at roomtemperature, and other was also placed at the show case. The result shows that the effectiveness of crisping dependedupon the physical structure or morphology of the respective vegetables. In general, the water temperatures of 30 and40oC and combined with the lengths of immersion time of 1-3 minutes were effective to improve the freshness andvigorousness of lettuce and leeks, while 7 minutes immersion was effective for kangkung and Chinese cabbage.

Abstract

Tujuan penelitian ini adalah untuk mengetahui pengaruh kolin defisiensi terhadapaktivitas enzim antiokasidant pada hati. Penelitian ini menggunakan tikus putih jenisWistar sebagai hewan percobaan yang diberikan pakan mengandung kolin 2,5 g cholinebitartrate /kg diet (CS) dan tanpa kolin (CD).Hasil penelitian menunjukkan bahwa total lipid, triacylglicerol, colesterol, danpospolipid pada hati meningkat dengan nyata pada CD. Kolin defisiensi (CD)menyebabkan menurunnya kandungan triacylglicerol, colesterol, pospolipid danmeningkatnya aktivitas enzim ornithine carbamoyltransferase pada serum. Aktivitasenzim superoxide dismutase, katalase, glutathione peroxidase dan kandungan ?-tocoperolpada hati menurun dengan nyata pada kolin defisiensi. Menurunnya aktivitas enzim dankandungan non-enzim antioksidan merupakan respon dari meningkatnya superoxideanion pada hati yang disebabkan oleh meningkatnya kandungan lemak hati. Disampingitu, meningkatnya aktivitas enzim ornithine carbamoyltransferase disebabkan karenameningkatnya kandungan triacylglicerol pada hati yang menandakan bahwa terjadikerusakan hati karena kekurangan kolin.

Abstract

The objective of this research was to determine the shelf life of the traditional snack food “rengginang” using the Labuza Model (the accelerated storage studies method (ASS Method)), as well as comparing the results with the extended storage studies (ESS) method. The rengginang was packed with the polyethelene plastic 0.03 mm, and store at room temperature with 75% of RH. The shelf life was determine using the accelerated storage studies method with Labuza Model, and extended storage studies method. The parameters observe in determination of shelf life were initial moisture content, critical moisture content, equilibrium moisture content, slope of sorption isotherm curve, moisture permeability of plastic used, ratio of plastic package are and product weight, and saturated pressure of storage condition. The result showed that the shelf life of rengginang calculated using Labuza Model (ASS Method) was 39 days, while the ESS method resulted 46 days. These was indicating that the Labuza model can be used to predicting the shelf life of rengginang like snack food.

Abstract

Water loss is a main cause of deterioration because it results not only in direct quantitative losses, but also in losses in appearance (wilting and shriveling), textural quality (softening, flaccidity, limpness, loss of crispness and juiciness), and nutritional quality. Transpiration is a physical process that can be controlled by applying treatment to commodity e.g. waxes or wrapping with plastic film or by manipulating the environment. Temperature management is the most effective tool for extending the shelf life of fresh horticultural commodities. The aimed of this experiment was to study the effect of modified atmosphere packaging of polyethylene (PE) plastic on physical quality of caisim during cooling storage. For that experiment, caisim were packed into PE plastic without hole (P1), 2 holes (P2), 4 holes (P4), 6 holes (P6), and 8 holes (P8). Products as controls were provided without packed. Then, products were stored in cold storage on 0 – 5oC for 4 days. The results of this experiment shows that packaging were significantly affected the decreasing of weight, moisture content, and the value of physical quality of caisim for 4 days, in spite of colors. Packaging of polyethylene plastic without hole can delay the deterioration or change physical quality of caisim more than 4 days.

Abstract

ABSTRACT Banana is the main product of a dry land farming at Gumbrih. The shelf life of fresh banana is very short and hence it is a great effort to find out how to preserve the banana for longer period. A method that can be applied is that by processing the fresh banana into processed foods, which has longer shelf life and easily to be modified into several products, which still retains the flavour of fresh banana. It was found that the knowledge of the local people (Gumrih villagers) on technology and banana processing was quite low and hence the recent program on course and practices of banana processing into dried banana (pisang sale) and banana powder (tepung pisang) is absolutely important. The activities were held at Desa Gumbrih, Kecamatan Pekutanan, Kabuapten Negara, on Friday, 16 September 2005, attended by 26 participants. Instead of course and practical works, the activities also have been conducted by active two-direction discussion between participants and tutor members. Since participants were curious to follow all the activities and we suggest that similar program is significant to be held on those banana producers around Bali and the short practical course would be more beneficial if it can be associated with marketing of the products.

Abstract

This research was conducted to determine the viability of Lactobacillus rhamnosus SKG 34 on various encapsulant and temperature. This research was divided into two steps. The first step, three kinds of encapsulant agent, i.e. maltodextrin, carrageenan, and alginate were used to microencapsulate Lactobacillus rhamnosus SKG 34. At this step, microcapsule yield, morphology, and viability of Lactobacillus rhamnosus SKG 34 was observed. Encapsulant with the highest population of Lactobacillus rhamnosus SKG 34 was extended into the second step. At the second step, microcapsule was treated with 7 variants of temperature, i.e. 45°C, 50°C, 55°C, 60°C, 65°C, 70°C, and 75°C. Data obtained were shown and explained with descriptive method. The result of the research showed that encapsulant variety gave different effects on microcapsule yield, morphology and viability of Lactobacillus rhamnosus SKG 34. The highest population produced by maltodextrin (1,24 x 109 ± 0,33 cfu/gr). The highest viability obtained at 45°C (3,37 x 108 ± 0,14). Lactobacillus rhamnosus SKG 34 can survive at adequate amount to give functional effect to the body with maximum temperature 55°C (4,78 x 107 ± 0,31cfu/ml).
