Melon Plants Citric Acid Sugar Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current melon varieties struggle to produce fruits with balanced combinations of organic acid contents, pH, and sugar levels, resulting in undesirable tastes and traits such as low sweetness, high acidity, and poor fruit characteristics, making it difficult to develop commercial products with improved organoleptic qualities.
Innovation Solution
Development of melon plants that incorporate specific low pH traits and genetic markers to achieve desired citric acid and sugar content levels, allowing for the production of fruits with elevated citric acid, reduced malic acid, and increased sugar content, while maintaining a pH range of 4.2 to 5.6, thereby creating novel and pleasant taste profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If melon varieties are bred to increase sugar content for sweetness, then sweetness is improved, but organic acid content and pH balance deteriorate, resulting in undesirable taste profiles
Solution Approach 1:
The patent applies parameter changes by selecting and breeding melon varieties with specific pH ranges (4.2-5.6) and organic acid content profiles. This involves changing the chemical composition parameters of the fruit to achieve an optimal balance between sugar content and organic acid content, creating a novel taste profile that is sweet yet not cloying.
Solution Approach 2:
The patent creates a composite chemical composition in the melon fruit by combining high sugar content with specific organic acid profiles (citric acid, malic acid, succinic acid). This composite approach allows the fruit to achieve a complex taste profile that integrates sweetness with pleasant acidity, avoiding the one-dimensional sweetness of conventional varieties.
2Object-affected harmful factors
If melon varieties are bred to decrease pH for sour taste, then sourness is improved, but sugar content and sweetness deteriorate, resulting in bitter or astringent flavors
Solution Approach 1:
The patent carefully adjusts the pH parameter within a specific range (4.2-5.6) rather than minimizing it. This controlled parameter change ensures sufficient sourness to create taste complexity while maintaining enough sugar content to prevent bitterness and astringency, achieving an optimal balance point.
Solution Approach 2:
The patent applies local quality by creating different chemical compositions in different parts of the fruit or at different developmental stages. The breeding program selects for varieties that maintain specific pH and sugar profiles in the edible mesocarp tissue, ensuring localized optimization of taste properties.
3Quantity of substance
If conventional melon breeding focuses on sweetness, then sugar accumulation is improved, but organic acid composition deteriorates, resulting in flat or monotonous flavor
Solution Approach 1:
The patent creates a composite chemical profile by simultaneously optimizing multiple components: sugars (sucrose, glucose, fructose) and organic acids (citric acid, malic acid, succinic acid). This composite approach ensures that sugar accumulation is enhanced while organic acid composition is maintained or improved, creating a complex and balanced flavor profile.
Solution Approach 2:
The patent changes multiple compositional parameters simultaneously, including sugar content, pH, and individual organic acid concentrations. This multi-parameter optimization creates a novel taste profile that is superior to conventional varieties in terms of flavor complexity and balance.
4Object-affected harmful factors
If low pH melon varieties are developed, then acid taste is improved, but fruit size and mesocarp proportion deteriorate, reducing commercial acceptability
Solution Approach 1:
The patent changes the pH parameter to a specific range (4.2-5.6) that provides pleasant sourness without the extreme effects seen in very low pH varieties. This controlled parameter change allows the fruit to maintain normal size and mesocarp proportion while achieving desirable acid taste, ensuring commercial acceptability.
Solution Approach 2:
The patent applies local quality by ensuring that the low pH trait is specifically expressed in the edible mesocarp tissue while maintaining overall fruit size and structure. This localized optimization allows the fruit to exhibit sour taste characteristics in the edible portion without compromising total fruit weight or mesocarp proportion.
