[Introduction of Craftsmanship]
First, the selection of raw materials are fully ripe, fresh, good flavor, rich juice, no pests and diseases, peach fruit with insufficient maturity must be post-matured.
Second, raw material pretreatment
1. Cleaning. After the raw materials are selected, they are washed and washed with clean water, then washed and washed, and then rinsed in 1% hydrochloric acid solution or detergent solution to remove residual pesticides, rinsed in clean water and drained.
2. Cut in half to remove the core. Use a half-cut nuclear machine. 3. Color protection by soaking. The raw material after halving and digging is put into 0.1%. Soak color in a mixed solution of ascorbic acid and citric acid.
Third, heating and beating
The fruit pieces are heated at 90 ° C to 95 ° C for 3 to 5 minutes to promote softening. The fruit pieces are beaten by a beater with a diameter of 0.5 mm to remove the peel.
Fourth, flavor adjustment
In order to increase the flavor, the pulp after the previous treatment needs to be adjusted. Add sugar, citric acid and L-ascorbic acid when adjusting. Its proportion is 100 kg of peach pulp, 80 kg of 27% sugar solution, 0.45 kg of citric acid, and 0.07-0.2 kg of L-ascorbic acid.
V. Homogeneous degassing
Homogenization is to make the pulp particles suspended in the juice break up into smaller particles and uniformly disperse in the juice to increase the stability of the juice and prevent delamination.
The homogenization method is to pass the coarsely filtered fruit juice through a high-pressure homogenizer, so that the pulp particles and colloidal substances in the fruit juice pass through small holes with a diameter of 0.002 to 0.003 mm under high pressure to become finer particles. Generally, 130-160 kg / cm2 homogenizer is used in production. A colloid mill can also be used for homogenization. When the juice flows through the slit with a colloid mill gap of 0.05-0.075 mm, the pulp particles in the juice are impacted and rubbed against each other due to the strong centrifugal force, thereby achieving the purpose of homogeneity. Fruits enter the gas such as oxygen, nitrogen, and carbon dioxide during juice extraction. Among them, nitrogen can cause oxidation of substances such as vitamin C and pigments, and corrosion of tinplate tins. Therefore, degassing must be performed in the following two ways:
1. Vacuum method. Fill the juice into a vacuum container and let the juice spray out in a mist form to degas. The emptiness obtained by the direct air method is 685-711 mm Hg or more, and the temperature is lower than 43 ° C.
2. Nitrogen exchange method. Juice flows from the top of an upright glass or stainless steel tube, and nitrogen gas is pushed in from the bottom of the tube. After adding nitrogen, numerous small bubbles are formed in the fruit juice, replacing the oxygen in the fruit juice to achieve the purpose of degassing.
Six, sterilization canning
The juice is heated to 95 ° C for 1 minute and canned immediately.
Seven, sealed cooling
Tighten the cap tightly and invert the jar for one minute. After sealing, it should be cooled down to 38 ℃ in sections and then stored in the warehouse.
沉淀;具有桃子汁风味,无异味;可溶性固形物达10%-14% Qualified fruit tea products are pink or yellow-brown, with a dark red color allowed; the juice is evenly turbid, with particulate precipitation after long-term standing ; peach juice flavor, no odor; soluble solids up to 10% -14%
