Patent CN104824622A reports a preparation method of pure persimmon jam, which retains the original flavor of persimmon, but the raw material is single and tasteless
Patent CN103027279A discloses a method for preparing persimmon jam by vacuum concentration, which avoids the loss of nutrition of persimmon jam by boiling at high temperature, but the cost is too high
Patent CN105192496A utilizes Aspergillus oryzae to ferment persimmon jam with rich and full aroma, but it takes a long time and the process is complicated
Patent CN105077193A compounded tangerine peel and persimmon, so that the jam has the effects of clearing away heat, reducing phlegm and relieving cough, but the long-term aging and boiling will cause serious browning of the jam
These studies on persimmon jam have less consideration for the complementarity of the properties and characteristics of the raw materials. While retaining the nutrition of the raw materials, the process is more complicated, the production cost is high, or the long-term cooking makes the browning of the jam serious, which affects the sensory quality.

Embodiment 1

[0042] Example 1 Optimization of process conditions for persimmon and hawthorn jam

[0043] The persimmon variety is Gongcheng Yueshi, and the fully ripe persimmon fruit is selected, and the hawthorn variety selected is Dajinxing.

[0044] Select the mass ratio of persimmon pulp and hawthorn pulp to be 1:1, 2:1, 3:1, 4:1, 5:1, 6:1 respectively, and the fixed total amount is 200g. Add 100g of water, add 20% white After granulated sugar, heat for 10 minutes, and use the sensory score as an index to optimize the optimal ratio of persimmon: hawthorn. The mass ratio of fruit pulp and water is selected as 1:1, 2:1, 3:1, 4:1, 5:1, 6:1 respectively, and the fixed total amount is 300g, wherein mixed persimmon pulp and hawthorn pulp are combined The ratio is 4:1, adding 20% ​​white granulated sugar and heating for 10 minutes, using the sensory score as an index, the optimal ratio of mixed fruit pulp and water is optimized. The amount of white granulated sugar added is 8%, 12%, 16%, 20...

Embodiment 2

[0062] Example 2 The color protection of persimmon hawthorn jam

[0063] Three kinds of color-protecting agents are selected to protect the color of the persimmon and hawthorn pulp, and these three kinds of color-protecting agents are sodium D-isoascorbate, tea polyphenol and disodium EDTA respectively. Taking L*, a*, and b* as indicators, the single factor test on the dosage of the three color-protecting agents shows that the dosage of sodium D-isoascorbate is 0.14%-0.42%, and the dosage of tea polyphenols is 0.022‰-0.066‰ , The dosage of disodium EDTA is 0.014‰-0.042‰. According to the single factor results, an orthogonal experiment was designed, and the compounding of the color-protecting agent was carried out with L*, a*, and b* as indexes. The factors and levels of the orthogonal design are shown in Table 7 below.

Embodiment 3

[0070] Example 3 Coloring of persimmon and hawthorn jam

[0071] The natural pigment β-carotene is used to color the jam, and it is added before the pulp is boiled. Place it at room temperature for 2 days, and perform sensory evaluation. The results are shown in Table 9.

[0072] Table 9 Results of toning test

[0073]

[0074] From the results of the coloring test, it can be seen that with the increase of the amount of β-carotene, the color of persimmon and hawthorn jam gradually deepens, and the score of the jam first increases and then decreases. When the amount of β-carotene is 0.10%, the score of the jam increases. The highest, so the final selection of β-carotene addition is 0.10%.
