Study of the Storage of Daicon Roots Depending on the Type of Packaging

The purpose of the work is to determine the safety of Daikon root crops depending on the packaging method, which will reduce product losses during storage and extend the duration of its consumption. Methods. 1. General scientific: the method of hypotheses – drawing up experimental schemes; the method of experiment – laboratory experiment schemes; the method of analysis and synthesis – forming conclusions and generalizations. 2. Calculation and analytical.Results. Minimum mass losses of 6.9–7.9% were observed in root crops packed in plastic boxes with microperforated high-density polyethylene film, thickness 20 μm. The difference between the minimum loss values is statistically significant and is 0.7–0.9% at NIP05 factor A = 0.65 and NIP05 factor B = 0.68. Under storage conditions of freshly harvested root crops, the average daily loss rate was 0.11–0.22%. The greater share of losses 0.11–0.15% is due to mass losses, only 0.02–0.07% due to loss of loose and sprouted% and damage by microorganisms. Ventilated root crops lost mass by 6.7–18.1% less daily than freshly harvested ones. Analysis of variance established that the average daily loss rate of mass is 95% dependent on the influence of other factors. These may be growing conditions, varietal characteristics, mode and duration of ventilation of root crops, which were not studied in this study. Conclusions. It was established that the yield of marketable root crops depends on the type of packaging and correlates with natural mass losses, the yield of standard and non-standard products; products affected by diseases, absolute shortages and total losses. The yield of marketable products has a strong inverse correlation with mass loss (r = –0.99571), absolute defect (r = –0.9995), and substandard products (r = –0.98656).
