Abstract

Continuous and repeated use of cooking oil at high temperatures accompanied by air and water contact can result in a hydrolysis reaction. The quality of the oil can be determined by carrying out the procedure for determining the free fatty acid content (FFA). Used cooking oil can be purified using an adsorbent/absorbent. Sugarcane bagasse and corn cobs have been widely used as adsorbents, but there has been no study comparing the increase in oil quality with these two adsorbents. This study aims to compare the color of the used cooking oil immersion with bagasse adsorbent and corncob charcoal adsorbent and determine the value of FFA levels of used cooking oil before and after soaking with bagasse adsorbent and corncob charcoal arsoben. The method used is fatty acid adsorption method and alkalimetric titration. From the observations, it was found that the color of the used cooking oil was fading after soaking with 3 types of adsorbents. The color of the immersion with a mixture of 1:1 adsorbent corncob charcoal and bagasse has the highest brightness level. FFA levels of used cooking oil after soaking also decreased from 0.207% to 0.141%; 0.132 %; and 0.094 %. The FFA content of used cooking oil by immersion in a 1:1 mixture of corn cob charcoal and bagasse was the lowest, which means the oil has the highest quality. It can be concluded that a mixture of 1:1 adsorbent of bagasse and corncob charcoal is the best adsorbent.

Abstract

The purpose of this study is to produce analog chees from sweet corn milk and soy beans with lower fat levels than cheese in general. This study uses a randomized design with a single factor in 3 treatments that is the manufacture of analogue of sweet corn milk and mily soil with the addition of lactic acid bacteria with 1%, 2%, and 3% concentration. The observed parameters include physical characteristics (texture, color, scent and taste) and chemical (protein and fat content). The results showed that analogical cheese physical characteristics have soft texture, yellow pale color, slightly scaved aroma and salt taste. The results of protein analysis ranged from 8,42% - 10,90% and fat 2,41% - 3,60%. The analogue of the analog cheese in this study can be categorized low fat cheats than the cheese from animal milk.

Abstract

The use of bulk cooking oil repeatedly with long storage time results in oil damage, such as increasing the peroxide value and acid number. So far, to overcome this problem, synthetic antioxidants are still used such as Butylated hydroxytoluene (BHT). When BHT added bulk cooking oil will be carcinogenic. Seeing this, it is necessary to look for alternative natural antioxidants. This study aims to seek out the effect of adding natural antioxidants, namely shallot powder to the peroxide value and acid number in bulk cooking oil with storage times of 0, 4, and 8 days. The peroxide number was determined by iodometric titration, while the acid number by acid-base titration. The data obtained were processed with statistics. The results of the statistical data of the Kruskal-Wallis test obtained a sig value of 0.000 less than 0.05, which means that there is an effect of adding shallot powder to the peroxide value and acid number. It shows that shallots are effective as natural antioxidants and can improve the quality of bulk cooking oil.

Abstract

Pineapple (Ananas comosus) is a source of protease enzymes. The protease enzyme present in pineapple is the bromelain enzyme. Bromelain enzymes are widely used in various industrial fields. The purpose of this experiment was to isolate the bromelain enzyme from pineapple plants, to test the activity of the enzyme, and to determine the optimum temperature of the enzyme. Isolation of the bromelain enzyme from pineapple was carried out by precipitating the pineapple fruit filtrate using table salt (NaCl). Then the crude extract of the enzyme obtained was tested on pieces of meat with variations in the testing temperature (room temperature, hot, and cold). The yield of the crude extract of the enzyme obtained from the experiment was 40%. The results of testing the bromelain enzyme activity of pineapple showed that room temperature was the best temperature for the enzyme to tenderize meat compared to hot and cold temperatures.

Abstract

     Agarwood tea is a prospective herbal tea product in the Indonesian marketplace. This product was made from agarwood trees, especially Aquilaria and Gyrinops genera. Agarwood leaves were the primary raw material of agarwood tea products. The leaves processing method into herbal tea products has adopted the conventional tea production method. This method has an essential contribution to maintaining the quality of agarwood tea products. This mini-review emphasizes the importance of systematic procedure and its effect on agarwood tea production technology. Agarwood tea production started with the standardization of raw material preparation. Raw material selection and sterilization were the essential procedure at this stage. Agarwood tea production after raw material preparation involves three steps: drying, chopping, and oxidizing. Dried leaves could produce agarwood tea with more robust characteristics than fresh leaves. Chopping the leaves is essential for agarwood tea product packaging. Oxidizing the leaves could produce agarwood tea with a better tannin concentration. It could be concluded that leaf preparation, drying, chopping, and oxidizing the leaves is an essential processing technology for agarwood leaves to produce a good quality tea.
