Against the backdrop of the "fresh-to-eat" and "health-focused" consumption trends, products like fresh-cut fruits, ready-to-eat salads and similar items have become sought-after offerings in the new retail sector. However, pain points such as difficulties in preservation, high wastage rates and short shelf lives have constrained the industry’s development. Shanghai Mugong, with its deep expertise in gas application engineering design and gas mixing equipment R&D, provides professional MAP preservation solutions to help food enterprises overcome these challenges and seize market opportunities.

In traditional packaging modes, fresh-cut produce is prone to browning and spoilage due to vigorous post-harvest respiration. Post-harvest wastage rates can reach as high as 15% to 25%, with a shelf life of only 1 to 2 days, severely limiting cross-regional expansion. Meanwhile, consumers’ growing demand for preservative-free products with retained nutritional value, coupled with the visual demands of the "aesthetic economy", has driven enterprises to upgrade their preservation technologies.

Tailored to the respiratory characteristics of water bamboo, Mugong has developed a full-chain MAP preservation solution. By precisely blending a ternary gas mixture (O₂+CO₂+N₂), the solution creates a multi-faceted preservation "shield" for the produce: an oxygen concentration of 1% to 5% inhibits the growth of anaerobic bacteria while maintaining the natural white color of water bamboo, preventing off-flavors and spoilage caused by anaerobic respiration; a carbon dioxide concentration of 3% to 8% effectively suppresses the proliferation of harmful microorganisms such as molds and bacteria, slowing down spoilage and fiber lignification of water bamboo; nitrogen, accounting for 85% to 95% of the mixture, serves as a filler gas to dilute oxygen, block oxidation reactions, keep packages plump and prevent mechanical damage to water bamboo during transportation.

After treatment with Mugong’s solution, water bamboo stored at a temperature of 0 to 5℃ sees its shelf life extended from the traditional 3 to 5 days to 2 to 3 weeks. The browning rate is reduced by over 60%, and post-harvest wastage is controlled below 5%. This fundamentally helps enterprises cut costs and boost efficiency, while preserving the inherent crisp texture and good appearance of fresh water bamboo.

Key equipment is an important guarantee for the preservation effectiveness of water bamboo. Mugong’s gas mixing equipment supports the arbitrary blending of oxygen, carbon dioxide and nitrogen, with customized parameters for different water bamboo storage scenarios, including whole shoot preservation, fresh-cut processing and vacuum MAP. The mixing accuracy error is ≤0.5%, perfectly matching the respiratory characteristics of water bamboo at different post-harvest stages. The equipment can dynamically adjust pressure fluctuations and store multiple sets of customized parameters, enabling quick switching between water bamboo and other fresh produce categories to meet the diversified processing needs of enterprises.

Equipped with a high-precision headspace gas analyzer, it takes only 7 seconds to detect gas concentrations inside packages, with an error margin of less than 0.2%. The system supports batch scanning for traceability, monitors real-time changes in gas concentration attenuation, issues early warnings of preservation risks, and significantly reduces terminal return rates and quality-related complaints.

In addition to supplying core equipment, Mugong offers full-cycle customized services to meet the needs of different stakeholders in the water bamboo industry. For growers, it provides solutions for on-site pre-cooling and initial MAP treatment; for processing enterprises, it delivers gas application engineering design, equipment commissioning and operator training; for distributors, it offers recommendations on cold chain coordination, with 0 to 4℃ being the suitable temperature for water bamboo storage and transportation, ensuring a closed-loop preservation effect. Whether for small-scale on-site preservation, large-scale production by medium and large processing enterprises, or quality control in new retail channels, Mugong can provide suitable solutions.

MAP preservation technology has become a key factor for the water bamboo industry to break through development bottlenecks and build competitiveness. Mugong’s solution not only extends the shelf life of water bamboo by 2 to 3 times, breaking geographical constraints to enable cross-regional distribution and long-distance supply, but also helps enterprises improve product pricing power by reducing wastage and enhancing appearance, facilitating the building of distinctive water bamboo brands. At the same time, eliminating the need for preservatives aligns with health consumption trends, enabling alignment with the needs of mainstream channels such as modern supermarkets, quality restaurants and fresh produce e-commerce platforms. With its professional gas mixing equipment and engineering design capabilities, Shanghai Mugong has established itself as a reliable partner for the water bamboo industry in achieving refined preservation and steady development.
