Loquat Fruit Quality Prediction via Lignified Cell Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for evaluating loquat fruit quality only reflect the current state and fail to predict future quality trends, leading to inefficiencies in postharvest storage, transportation, and sales strategies, resulting in significant economic losses due to perishability and seasonal imbalances.
Innovation Solution
A method involving randomly selecting samples, calculating lignified cell density and equivalent cell wall thickness, and determining a lignification trend value to assess and grade fruit quality, which guides pricing and storage strategies based on predicted quality changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physiological indicators such as fruit firmness, lignin content and juice yield are used to evaluate loquat fruit quality, then the current quality state can be reflected, but the future quality trend cannot be predicted in advance
Solution Approach 1:
The patent applies preliminary action by measuring the lignification trend value (TV) of loquat fruits before storage and transportation. This predictive indicator allows stakeholders to anticipate future quality changes and make informed decisions about storage conditions, transportation timing, and sales strategies in advance, rather than waiting for quality degradation to occur
Solution Approach 2:
The patent implements beforehand cushioning by using the lignification trend value to predict quality changes and pre-adjust storage and transportation conditions. By identifying fruits with high lignification trends before deterioration occurs, appropriate protective measures can be taken proactively to cushion against quality loss during postharvest handling
2Loss of energy
If loquat fruits are sold in real time without storage, then perishability losses are reduced, but seasonal and phased surplus leads to structural imbalances in supply
Solution Approach 1:
The patent enables preliminary assessment of loquat fruit quality and lignification trend before storage. This allows producers to make informed decisions about which fruits are suitable for storage and for how long, facilitating better planning of storage capacity and timing to balance supply throughout the season
Solution Approach 2:
The patent introduces dynamic classification of loquat fruits based on their lignification trend values. Fruits are categorized into different groups (e.g., suitable for immediate sale, suitable for short-term storage, suitable for long-term storage) based on their predicted quality trajectories, enabling flexible and adaptive supply chain management that responds to both perishability constraints and market demand variations
3Duration of action of moving object
If storage and logistics preservation technology is extended to improve supply cycle, then seasonal imbalances are reduced, but postharvest lignification and perishability increase
Solution Approach 1:
The patent applies preliminary action by determining the lignification trend value of loquat fruits before storage. This predictive information allows for optimized storage duration planning - fruits with low lignification trends can be stored longer with confidence in maintaining quality, while fruits with high trends are prioritized for immediate sale or special handling
Solution Approach 2:
The patent enables parameter-based differentiation of storage strategies based on lignification trend values. Different storage conditions (temperature, humidity, atmosphere composition) and durations can be assigned to different fruit groups, optimizing the balance between extending supply cycle and minimizing postharvest losses

AI summary
A method for guiding a sales strategy of loquat fruits by evaluating and predicting quality of the loquat fruits is provided. The method slices and stains an equatorial plane of an loquat fruit and calculates a lignified cell density P of the equatorial plane of the loquat fruit, so as to guide a current price of a batch of loquat fruits. The current price of the loquat fruits increases as P decreases. The method analyzes a growth stage of the lignified cells and predicts a quality change trend value T of the batch of loquat fruits, so as to guide a storage strategy based on T. The loquat fruits are suitable for storage and transportation when T is high, and the loquat fruits need to be sold as soon as possible when T is low.
