[Effects of different substrates on low temperature fresh ginseng]

Area of Science:

• Agricultural Science
• Food Science
• Biochemistry

Background:

• Fresh ginseng (Panax ginseng) is a valuable crop requiring optimal storage conditions to maintain quality.
• Enzyme activity, saponin content, and protein concentration are key indicators of ginseng freshness and viability.
• Traditional storage methods may lead to degradation, impacting market value and efficacy.

Purpose of the Study:

• To evaluate the effectiveness of different substrates for preserving fresh ginseng at 4°C.
• To determine the optimal storage conditions for maintaining ginseng quality over six months.
• To assess the impact of storage on key biochemical markers like enzyme activity and nutrient content.

Main Methods:

• Fresh ginseng was stored for six months at 4°C using perlite as a substrate.
• Superoxide dismutase (SOD) and peroxidase (POD) enzyme activities were measured.
• Ginseng saponin content and total protein concentration were quantified.

Main Results:

• Perlite preservation maintained good ginseng appearance and survival rates after six months.
• Ginseng stored in perlite exhibited lower SOD and POD enzyme activities.
• Significantly higher saponin and protein content were observed in perlite-stored ginseng.

Conclusions:

• Perlite is an effective substrate for the long-term fresh storage of ginseng.
• Storing ginseng in perlite at 4°C preserves its biochemical integrity and quality.
• This method represents the best practice for maintaining fresh ginseng viability and nutritional value.
