The social and economic benefits of raspberry planting and processing are considerable. Although the berry fruit is very popular at home and abroad, in order to create greater profits, the cultivation and processing of raspberry should also be developed in the direction of scale and industrialization. Here are some techniques to promote and support the industrialization of raspberry.
Intensive scaffoldingThe decentralized cultivation of raspberry has been difficult to meet the large demand for raspberries in domestic and foreign markets. Intensive trellis planting can be used to invest in local cold storage and storage and processing nearby. This method is conducive to management and management, and is conducive to the application of relevant high-yield technologies to produce high-quality berry fruit.
Preservation processingRaspberry water content up to 70% ~ 80%, it is easy to break and rot. If fresh fruits are picked and freshly processed in time, even in the field, fresh-keeping treatments will be started. For example, the use of a mixture solution of 1.5% sodium chloride, 0.2% citric acid, and 2.5% calcium chloride for "preservation of color hardening." The treatment helps to protect the natural color of the berry, and strengthens its hardness so that it is not easily broken. The processed berries can be frozen again to produce a better commercial quality product.
Frozen fresh berriesThe fresh berry was treated with the “protective color curing†method according to the above method, and then soaked in a solution of “0.3% sucrose ester + 30% white granulated sugar†for 30-50 minutes, and then snap-frozen at a low temperature below -38°C. The raspberry was frozen at 6~8 °C, packed in small plastic bags, packaged in cartons, and placed in cold storage. The product processed by this method was thawed and tasted and tasted much sweeter than the original raspberry, and its shape, color, and mouthfeel did not change much.
Dried Raspberry ExtractThe berry fruit (including the secondary fruit that has lost the fruit's edible quality) is decontaminated, washed, and then acetic acid with a mass fraction of 2.5% is cooked at 95°C; after draining, the water is added according to its mass ratio. Nitrogen compounds (amino acids, hydrolyzed proteins, etc.) are stirred well, beaten, concentrated, dried and then pulverized to 80-120 mesh. Vacuum packed packaging is the product. This method is characterized by a simple process and easy production. The acetic acid water boiled has a very good effect of inactivating eggs, bacteria and molds, and can also protect berry acids, organic acids and the like in the berry fruits from damage; using nitrogen-containing compounds and reducing sugars, with loaded berry fruits The significance of the active ingredient can also enrich its taste and flavor, including the flavor produced by the carbamide reaction. The dried raspberry concentrate product produced by this method contains more than 99% of raspberry components and is easy to store. It can be widely used as a nutrient, food and beverage additive.
Raspberry drinkUsing berries and leaves can produce a variety of drinks, especially the use of raspberry leaf tea can produce economic benefits. The low cost of raspberry leaf tea, its hypoglycemic effect, anti-aging, anti-cancer, weight loss, beauty, and the role of slowing women's menopausal response have received extensive attention and can serve as an important support point for the development of raspberry planting and processing industries. . The berry is made into dried raspberry powder and can be packaged directly into a teabag; after the raspberry leaves are protected from odor, it is the crude tea product.
Medicinal raspberry productsImmature fruit berry has long been used to replace the famous Chinese medicine raspberry in clinical application, as the latter has the "Yishen, solid essence, urinary diuretic effect" for the prevention and treatment of kidney deficiency enuresis, urinary frequency, impotence and premature ejaculation embolism . Animal experiments have shown that berry fruits and leaves can increase the quality of the ovary, as well as protect the health of the vaginal wall, and increase the quality of testis and the number of sperm. The production method is as follows: the immature fruit berry is picked up, placed in boiling water, or heated and steamed, and dried and served. It can be used in combination with lemongrass, epimedium, pepper, Cistanche, Poria, ginseng, pilose antler, donkey-hide gelatin, chicken colony, sheep fetus, Placenta, etc., and it can further develop health care products that have never been seen on the market. product
