Extraction, Purification, Optimization, and Application of Galactomannan-Based Edible Coating Formulations for Guava Using Response Surface Methodology

Abstract

Galactomannan from fenugreek and guar seeds were extracted, purified, and used in edible coatings, optimized via response surface methodology. The results showed that the emulsifying capacity and stability of fenugreek galactomannan (FG) and guar galactomannan (GG) increased with increase in the concentration of galactomannan up to 0.5–1%. The average optimized values of FG and GG in edible coatings were predicted to be 1.71% and 2.11% for weight loss, 0.72% and 2.14% for firmness, 1.02% and 1.44% for TSS, 0.83% and 1.36% for pH, 1.03% and 1.44% for acidity, respectively. Significant decrease in weight loss and maximum retention of firmness was observed in coated guava. The TSS increased up to a certain storage period in all treatments and decreased as the storage period progressed, whereas pH exhibited an increasing trend while a significant decrease in acidity was observed. The findings revealed that the shelf life of guava could considerably be improved by incorporating 1.24% galactomannan from GG and 1.01% from FG in the edible coating.

Optimization of Edible Coating Formulation Using Response Surface Methodology for Delaying the Ripening and Preserving Tomato (Solanum lycopersicum) Fruits

“…Lycopene is a carotenoid associated to color change during ripening [45,46]. Previous studies have shown that in ripening fruits chlorophyll degradation and lycopene accumulation are positively correlated [47]. Te present study shows that lycopene and β-carotene contents were lower in treated fruits compared to control fruits, indicating that the coating solutions formulated with cofee leaf extract, starch, and Gum Arabic slowed down the degradation of chlorophyll, and the synthesis of carotenoids as well.…”

Application of Response Surface Methodology in Dance Health and Training Safety

“…Response surface methodology (RSM) is a test design method proposed by Box et al It is an optimization method that integrates test design and mathematical modeling [22][23][24][25][26][27]. By performing tests on representative local points, the functional relationship between factors and results in the global scope is regressed and fitted, and the optimal level value of each element is obtained.…”

“…In recent years, the progress of computer and information technology [18][19][20][21][22][23] has also provided a powerful tool for the dance health and training safety analysis of this study. In order to promote the safety of dance teaching and competition, this study adopts response surface methodology [22] to study the accidental injuries and characteristics in dance teaching and competition, analyzes the causes, and puts forward corresponding safety precautions to reduce the incidence of injuries in safety measures.…”

Combined with the causes and nature of accidental injuries caused by inadequate safety precautions in dance teaching and training, this paper puts forward safety precautions suitable for dance sports teaching and competition, which have certain guiding significance for dance athletes to avoid accidental injuries, enhance their awareness of prevention, and prevent injuries in teaching and competition.…”

Postharvest Quality Improvement of Tomato (Solanum lycopersicum L.) Fruit Using a Nanomultilayer Coating Containing Aloe vera

“…Polysaccharide-based coatings are the most used materials to extend the shelf life of fruits and vegetables. Examples of these materials include sodium alginate [ 16 ], chitosan [ 17 ], galactomannans [ 18 ], pullulan [ 19 , 20 ], pectin [ 21 ], among others.…”
