Influence of Natural Extracts Dipping to Maintenance Fruit Quality and Shelf Life of Egyptian Guava

Shorter shelf life and faster deterioration of fruits after harvest are the major constraints with the peach production in the subtropical regions. Pre-harvest application of GA3 and chloride & nitrate of calcium were tried in a RBD experiment for enhancing peach fruit quality and reducing fruit deterioration during shelf life studies of five subtropical peach cultivars. At harvest fruit quality parameters viz. TSS, acidity, firmness etc. were influenced greatly by the treatments. Other physical properties of the fruit such as fruit weight, size and yield were not influenced much. Physiological weight loss during storage and the deterioration of other fruit characteristics were considerably lowered by calcium treatments. Foliar application of Calcium nitrate (1%) was found to be superior over calcium chloride (2%) for improving fruit quality and shelf life.

Lychee is a well-known subtropical fruit, much appreciated for its attractive red peel and excellent taste, but the fruit is very prone to postharvest peel browning and decay. China is the world leader in both acreage and yield of lychee production. Extensive research has been conducted to extend the fruit quality and shelf life. The talk presents a general review of the current research on postharvest physiology and shelf life preservation technologies of lychee in China.

Quality And Shelf Life

Abstract The adoption of melon hybrids by the productive sector necessitates a prior evaluation of the productivity, quality and shelf life of their fruits. Due to the different environmental conditions under which the hybrids are evaluated, an accentuated genotype-environmental interaction is expected to become apparent and likewise play important role in manifestation of phenotypic traits. The objective of the present work was to evaluate melon hybrids in the state of Rio Grande do Norte. The adaptability and stability of the genetic values were estimated by the HMRPGV method (Harmonic Mean of the Relative Performance of Genetic Values) for the following traits: yield, and soluble solids (SS) content in the period between 2010 to 2015. In 2017, the more promising melon hybrids from previous trials were evaluated under commercial conditions to determine the fruit’s yield, quality and shelf life. The predominance of the complex part of the genotype-environmental interaction was verified for both yield and SS content. Hybrids HC-02 and HC-11 show promising traits when grown under the conditions of the Mossoró-Assu Agricultural Complex owing their high stability, adaptability, yield, and fruit quality. Hybrids HC-02, HC-11, and ‘Hy Mark’ are suitable as international exports due to their long shelf life.

Quality And Shelf Life

This study provides an application of new, natural source of crude peptide extract from Lablab bean (CPL). Use of additive such as benzoate in the rice noodle industry is a common practice and has several bene?cial effects on quality and shelf-life. However, the shelf-life of semi-dried rice noodles can be extended by crude peptide extract with acceptable quality when compared to other additives. This research aimed to extract CPL and determine its effect on the growth of microorganisms. The use of the CPL to extend the shelf-life of semi-dried rice noo-dles was compared with other natural extracts (chitosan and thymol) and benzoic acid. The CPL samples were extracted using 5% pepsin and incubated for up to 24 h. CPL at 200 mg/mL could be used as the growth inhibitor for Bacillus cereus but not for Staphylococcus aureus and Escherichia coli. It was found that noodles with CPL had the highest cooking loss (4.69) and lowest tensile strength (22.6 g.force). Overall-liking scores showed slightly liked (6.0 out of 9) and 68% of the consumers accepted the CPL-treated noodles. Shelf-life testing showed that CPL could extend the shelf-life of the noodles for 3 days than the control (1 day). Using 200 mg/mL of CPL could extend the shelf-life more than 3 times when compared to the control noodle (no additive). The CPL was nearly as effective as benzoic acid that could be kept for 3 days. Hedonic score in overall-liking showed a slightly like (6.2) for the noodles with CPL. This study suggests the application of adding CPL could be used as new natural additive and seems to be promising to apply in many food products such as pasta or sausages.
