In recent years, there has been an increasing interest in using food additives from natural sources to improve taste, texture and extend the shelf-life of foodstuffs. The aim of this study was to examine the quality changes in trout treated with lemon juice for 21 days. Fish were divided into T0, T1, T2 and T3 and treated with 0, 1%, 2% and 3% lemon juice respectively. The lowest pH was found in T3 followed by T2, T1 and T0. A significant difference in total volatile base nitrogen (TVBN), peroxide value (PV) and free fatty acid (FFA) was observed between the control and treatments, with the lowest increase in T3 followed by T2. Total plate count (TPC) crossed the limit in T2 and T3 on the 21st day, whereas in control and T1, the permissible limit crossed on the 12th and 18th days respectively. The sensory panel rejected the control on the 12th day and T1 and T3 on the 18th day; however, T2 remained acceptable till the 21st day, thus showing the promising effect of lemon juice on the quality of trout fillet and thereby increasing the shelf-life of the product by nine days.

Patulin (PAT) is a prevalent mycotoxin frequently found in fruit and its derivatives, such as apple, pear, and juices. Despite worldwide attempts to diminish the levels of PAT at every stage of the fruit production process, its contamination rate remains high. This mycotoxin is worrisome due to its potential adverse impacts on human health. Eating PAT-contaminated fruit can lead to acute and chronic health issues. It is established, by the Joint FAO/WHO, a maximum tolerable daily intake for PAT at 0.4 µg/kg/day. Therefore, monitoring for PAT contamination is essential for the safe consumption of fruits and fruit-related products such as juices, purees, ciders, jams, marmalades, vinegar, and dried fruits. PAT has physiochemical properties that enable its survival in cold, hypoxic, acidic, or high-temperature conditions. Ideally, detoxification procedures should aim to reduce the level of toxins to safe levels whilst preserving the nutritional and palatable values of the treated commodity. There are several physical, chemical, and biological techniques available for PAT detoxification. However, while physical and chemical methods can remove PAT, they may also lower the nutrient quality and organoleptic properties of the food. Biological detoxification is an effective, environmentally friendly, easy, and cost-effective method, as established by existing research. It has proven efficacy in food safety research and regulatory compliance programs. Probiotics have been studied for their potential to reduce PAT in foods via different mechanisms (such as adsorption, degradation, and transformation), as well as all their health-beneficial effects. In this review, the reduction of PAT in fruit-based products using probiotics or potential probiotics is widely discussed.
