This paper presents inventory models for fresh agriculture products with time-varying deterioration rate. Due to the particularity of fresh agriculture products, the demand rate is a function that depends on sale price and freshness. The deterioration rate increases with time and is assumed to be a time-varying function. In the models, the inventory cycle may be constant or variable. The optimal solutions of models are discussed for different freshness and the deterioration rate. The results of experiments show that the profit depends on the freshness and deterioration rate of products. With the increasing inventory cycle, the sale price and profit increase at first and then start decreasing. Furthermore, when the inventory cycle is variable, the total profit is a binary function of the sale price and inventory cycle. There exist unique sale price and inventory cycle such that the profit is optimal. The results also show that the optimal sale price and inventory cycle depend on the freshness and the deterioration rate of fresh agriculture products.

BACKGROUND: It is very important to monitor the residual characteristics of pesticides in pre-harvest fresh ginseng to ensure consumer safety. METHODS AND RESULTS: Forty-eight fresh ginseng samples were collected from 8 ginseng-growing fields 10 days before harvest and pesticide residues in fresh ginseng with and without rhizome (head of ginseng) and rhizome were analyzed for 320 pesticides by using GC-MS/MS and LC-MS/MS. As a result of the pesticide residue analysis, the number of pesticides detected from the fresh ginseng with rhizome, that without rhizome and rhizome were 26, 25, and 40, respectively, indicating that high number of pesticides found in rhizome, compared with the other parts. Pyraclostrobin was detected with the highest frequency in all samples, reaching to 21.2% in fresh ginseng with rhizome, 16.8% in that without rhizome, and 14.8% in rhizome. CONCLUSION: The residue levels of pesticides detected did not exceed their maximum residue limits, in spite of residual data in fresh ginseng before harvest. The amounts of the estimated daily intakes of all the detected pesticides were found to be from 0.018 to 1.818% of their acceptable daily intakes, indicating that concentrations of pesticides detected from fresh ginseng with and without rhizome collected before harvest do not pose the immediate health risks.

This study was performed to evaluate the quality characteristics of three deboned categories of chicken thigh meat: one which was slaughtered and deboned in the same plant (fresh); one which was slaughtered, deboned, frozen, and thawed in the same plant (frozen-thawed); and the last which was slaughtered in a plant, deboned in a different plant, but then transferred to the original plant (fresh-outside). Surface color, drip loss, 2-thiobarbituric acid reactive substances (TBARS) value, sensory evaluation, and total aerobic bacterial counts of the chicken samples were determined. Moreover, the torrymeter was used to measure the differences in freshness of the chicken meat. The surface color and the TBARS values did not show significant differences among the three categories. However, the total aerobic bacterial counts of fresh-outside and frozen-thawed chicken meat were significantly higher than the fresh chicken meat on the first storage day, and the drip loss of frozen-thawed chicken meat was significantly higher than the fresh-outside and fresh chicken meat. In addition, the sensory evaluation of frozen-thawed chicken meat was significantly lower than the fresh-outside and fresh chicken meat. Torrymeter values were higher in fresh chicken meat than fresh-outside and frozen-thawed chicken meat during the storage period. These results indicate that the quality of frozen-thawed chicken meat is comparatively lower than the fresh chicken meat, and the torrymeter values can accurately differentiate the fresh-outside and frozen-thawed chicken meat from the fresh ones.

This study investigated the online transaction status of low-carbon certified fresh agricultural products and analyzed the low-carbon certified premium. For two months from March to April 2022, eight products (rice, apple, pear, sweet persimmons, paprika, tomatoes, cherry tomatoes, and lettuce) were surveyed at major online shopping malls. The low-carbon certification premium was analyzed using hedonic price analysis model. As a result of the online market survey, the low-carbon certified agricultural products were not traded in the case of rice, cherry tomatoes, and paprika. And the proportion of low-carbon certified agricultural products in the case of tomatoes and lettuce was low. As a result of the low-carbon premium analysis, of the five products that analyzed the low-carbon certification premium, four products excluding pear did not have a low-carbon certification premium. Thus, it is necessary to expand the sale of the low-carbon certified agricultural products by distributors, and various efforts to secure the premium of certified agricultural products are important.

Purpose: With the emergence of high technology in China, online shopping distribution of fresh agricultural products have been developing rapidly. This study built a model to investigate how perceived quality of products and logistic services, perceived risk, and perceived cost affect intention to buy fresh agricultural products in an Internet environment. Especially, in the purchasing process, attitude may work as an important mediator. Research design, data and methodology: To achieve the objectives of this study, Chinese respondents were asked to fill in a questionnaire through the China online survey website. With 520 available data, regression analysis was used to test the hypotheses. Results: Results indicate that perceived quality of fresh agriculture products and perceived logistics service quality have a significant positive impact on attitude and purchase intention. Results also reveal that perceived risk and perceived cost affect attitude and purchase intention negatively. Finally, results imply that attitude has a positive effect on purchase intention, which is the unique mediator in the online shopping process. Conclusions: This study suggests that managers in the online shopping distributions of fresh agricultural products should improve the quality of products and logistics services along with the reduction of the perceived risk and cost to compete in the China market.
