Abstract

Apart from being sold in whole form, fish is also sold in ready-to-use fillets. Fillets were easier for buyers because they were practical, easy to use, and clean. The disadvantage of serving in the form of fillets was that they were very susceptible to damage due to the ease of damage. Fish fillets have a high moisture and protein content. Without any protection, this material will quickly deteriorate. This study aimed to determine the effect of ginger and turmeric extracts on catfish fillets stored at cold temperatures The study used a factorial complete randomized design with the ratio of ginger and turmeric extracts as the first factor and storage days as the second factor. The results show that the use of ginger and turmeric as additional ingredients in the storage of catfish fillets was less effective in inhibiting fillet deterioration. The moisture content of the catfish fillets decreased from 82.66% to 70.51% after 6 days of cold storage. The pH value of the catfish fillet increased, while water-soluble protein and TVB-N were varied for some treatments. The pH value of fresh fish fillets without the addition of ginger and turmeric was 5.50 and reached 6.30 after 6 days of cold storage. Fillets with turmeric and ginger have a lower pH (6.15), and the ratio of the rhizome extracts did not significantly affect the pH value. According to the TVBN value, ginger and turmeric extracts could maintain the quality of fish fillets for up to 4 days at cold temperatures. Further research needs to be done to study the effect of packaging on the fresh fillet quality.

Abstract

An edible coating is a thin layer of hydrocolloid materials such as polysaccharides, polypeptides, lipids, and composites. Apples are one of the fruits that often undergo minimal processing, such as slicing. Cut apples are susceptible to damage, which can lead to rapid browning, to slow this reaction, an edible coating can be applied. This study aimed to determine the quality of apple slices after being treated with an edible coating made from arrowroot starch with lime juice and mint leaf during storage. This study used a Completely Randomised Design with two factors: storage time (0, 2, 4, and 6 days) and the concentration of lime juice and mint leaf. The results showed that adding lime juice and mint leaf did not significantly affect water content, vitamin C, and weight loss of apple slices, while the longer the storage, the more damaged the sliced apples were. Weight loss, antioxidant activity, total phenols, vitamin C, and total aerobic bacteria decreased during storage. The treatment of adding 13% lime juice and 10% mint leaves was able to suppress the total number of bacteria to 5.77 log 10 CFU / g at a shelf life of 6 days. The treatment of adding mint leaves and lime extract was able to inhibit damage to sliced apples for 6 days of storage
