Postharvest preservation of agricultural products has always been the important problem related to agricultural sustainable development, using natural plant extracts to fresh fruits and vegetables can reduce the chemical synthetic fungicides stesweet stevia adverse effects on human health, and effectively prevent resistance of plant pathogens.
Can be applied to the fruit and vegetable fresh-keeping of natural plant extracts mainly natural flavor and Chinese herbal medicine, the main pathogenic bacteria in the process of the extraction of fruit and vegetable fresh-keeping has strong inhibitory effect. Natural preservative antistaling agent, the active ingredient is mostly volatile oils, mainly by acting naringenin price on microbial cell membrane or energy metabolic pathway antibacterial effect.
Natural plant extracts in the main application for fruits and vegetables have a dip dip, fumigation, spray, or combined with tin foil and film coating, such as the carrier, but it is lack of mature industrialization application technology. Development of plant source of fruit and vegetable fresh-keeping agent future research should focus on plant extracts, the active ingredient and the structure-activity relationship, and industrialization application of system engineering.
Our long-term dependence on chemical preservative for fruits and vegetables, but with the increase of use, drug resistance and on human health hazard problem increasingly prominent. Plant extracts of green, environmental protection, is turmeric extract powder becoming a hot spot of antistaling agent development in recent years. Discusses the antistaling agent development of plant resources, extract method, sterilization principle and its application progress, points out the development process will face the problems and prospects of the division as a goal, in the extraction process, drying technology and production technology, continuous innovation and improvement, finally overcome the low chitosan caused by melting and plant extracts of solidification problem caused strong moisture absorption, using advanced, reasonable, scientific production technology, the natural plant essence extract breakthrough progress has been made on the quality of the product. Pumpkin extracts have obesity prevention and treatment of chronic osteomyelitis, cure asthma for, spuc, maternal stimulate the secretion of milk, and so on.
Pumpkin is one of our traditional fall blood sugar food, Japan in the 1970 s the pumpkin powder to treat diabetes of the application report. Over the years, many researchers have been trying to squash the pumpkin seed extract prevention and control of diabetes research, put forward the pumpkin pectin, cyclopropyl amino acids and trace elements of zinc, chromium (Cr) may play a leading role to prevention and treatment of diabetes.
