Abstract

Shellfish are the Bivalvia Group which is one of the source of animal protein. After harvested, all fishery products, including shellfish, experienced rigor mortis which is an indicator of quality changes. Rigor mortis affect the texture of shellfish and caused the softening due to the activity of proteolytic enzymes. This review aims to provide information, of how Adenosine Triphosphate (ATP) plays a major role in changing the postharvest quality of shellfish and how to maintain its postharvest quality. Based on the literature study, it was found that rigor mortis is a process in which fishery products lose their flexibility due to increased muscle tension and correlates with a decrease in ATP. The degradation of ATP components begins 6 hours after harvest, especially in high temperature. In general, shellfish becomes soft quickly during storage which indicates damage. The harvest process and storage conditions influence postmortem changes. Various types of cooling systems have been widely used to preserve shellfish at temperatures of -4 to 0℃: cold storage, ice water, shaved ice, dry ice and ozone-shaved ice combinations. Shelf life can be extended by storage at sub-zero temperatures. Storage temperature can limit softening by reducing protease activity. Cooling temperatures can be advantageous in maintaining freshness and suppressing the growth of harmful microbes.

Abstract

Homemade tomato sauce products have the advantage of having a composition that can be ensured to contain minimal harmful chemicals. However, like other processed products, of course, the product will experience a decrease in quality along with the length of storage time. This study aims to determine changes in the quality of tomato sauce produced on a home scale (homemade ketchup) during one month of storage at storage temperatures of 10oC, 250oC, and 350oC. The method used to predict shelf life is the Arrhenius calculation model, which observes changes in pH, aw, and Total Microbes. The findings showed that the pH of tomato sauce tended to decrease with the length of storage time. The number of microbes increased with the increasing temperature and length of storage. Meanwhile, temperature and length of storage did not affect water activity. However, aw tends to increase with the temperature and length of storage. The results of estimating the shelf life with the Arrhenius model based on the water activity (aw) parameter showed that the shelf life of the sauce was 151.75 days with a quality decline rate of 0.001068/day at a storage temperature of 10oC; 96.07 days with a quality decline rate of 0.001685/day at a storage temperature of 25oC and 72.6 days with a quality decline rate of 0.002227/day at a storage temperature of 35oC. The implications of this study indicate that storage at 10oC can extend the shelf life of both tomato sauce products, so producers and consumers need to consider the optimal storage temperature based on the results of this study.

Abstract

Repeated use of cooking oil at high temperatures encourages this oxidation of oil. This condition often creates a dilemma, on the one hand for traders tend to prioritize economic value over health aspects. This research aims to identify and analyze the TOTOX value in used cooking oil which is used by food sellers in the Merak neighborhood, Banten. Research methods is a laboratory experiment by taking 5 samples of used cooking oil Random from different sellers. The research results show that the lowest peroxide value was found in catfish pecel sellers (0.57 mek O2/kg) and highest among gado-gado sellers (2.84 mek O2/kg), but still below the maximum limit. P-anisidine value with the highest levels among warteg sellers (22.57) and the lowest among sellers of flour fried chicken (0.98). Mark TOTOX with the highest levels at warteg sellers (27.57 mek O2/kg) and the lowest at seller of flour fried chicken (5.30 mek O2/kg). All used cooking oils are tested in This researchstill meets the requirements for peroxide figures. However, there are three sellers (Warteg, Pecel Lele, and Gado-gado) which has a TOTOX value exceeding the permitted limit. Therefore, it is important to carry out routine monitoring of The quality of used cooking oil, especially from sellers who have a high TOTOX value, is useful ensure consumer safety.

Abstract

Granulated palm sugar is a natural sweetener product that is gaining popularity due to its low glycemic index and its beneficial health effects. There are two primary methods of producing palm sugar: direct production from fresh sap and reprocessing of molded palm sugar. This study aims to investigate the impact of various production methods on the physicochemical and organoleptic properties of granulated palm sugar. The research employed a Completely Randomized Design (CRD) with one factor, namely the cooking method, consisting of direct production from fresh sap (PL) and production through reprocessing molded sugar (PC). The observed parametersincluded moisture content, ash content, yield, reducing sugar content, and organoleptic tests covering color, aroma, taste, and texture. The analysis results showed significant differences in all tested physicochemical parameters. The PC granulated palm sugar had a lower moisture content, yield, reducing sugar content compared to PL and higher ash content. In the organoleptic tests, PC palm sugar scored significantly higher in terms of color, aroma, taste, and texture. This study concludes that the production method using molded sugar is more recommended, as it produces palm sugar with a more stable quality, meets the standard, and is more preferred by consumers. This research is expected to serve as a basis for determining the appropriate method for producing high-quality granulated palm sugar.
