For the production of rouge chocolate product-coating:

Being adjusted respectively using the chocolate catsup temperature of compound lard 3, PMF is 45 DEG C, wafer is immersed above-mentioned skilful In gram force sauce, takes out the vibration of waffle dry doubling and remove extra sauce.It is placed on to be put into 6~8 DEG C of baking ovens and places cooling 40min After take out.It is prepared into respectively and stores for future use (20-22 DEG C of temperature, humidity≤65%) for rouge coating product 1,2.

Sensory evaluation:

Receiving stemness can be evaluated according to following judgment criteria:

In 6~8 DEG C of baking ovens record finger contact chocolate surface until finger on do not adhere to any chocolate when Between.Time is shorter, illustrates that receipts stemness is better.~

Mouth fusibleness is evaluated according to following judgment criteria:

It will prepare and be placed in climatic chamber that (25 DEG C, 55%) appropriateness is for rouge chocolate pie block and coating product After placing 2 days, chocolate is taken out, carries out the evaluation of mouth fusibleness.

" √ " expression is melted quickly in mouth, no wax sense；

"=", indicates to melt in mouth relatively slowly, slightly there is wax sense, is subjected to；

"×" expression is melted very slowly in mouth, and wax sense is obvious, unacceptable.

Product glossiness is evaluated according to following judgment criteria:

By being sealed in plastic packaging bag for rouge chocolate pie block product for preparation, and (25 are placed in climatic chamber DEG C, humidity 55%) it is taken out after 30 days, observe the gloss of chocolate product.Evaluating member is evaluated with 0-5 points of systems.4-5 table Show that product glossiness is good；2-3 indicates that product has certain gloss, slightly dark；0-1 indicates that product tarnishes, gloomy.Score is got over Height, representative products glossiness are better.

Test result is as follows shown in table 6.

Table 6

In addition, chocolate pie block 1-2 is slightly softer than chocolate pie block 4-5 in hardness, mouthfeel is more soft, and mouthfeel is closer Pure rouge chocolate.

For the production of rouge chocolate cream:

Formula and method as previously described, weigh mixing grease 4 and LSS20-03 prepares chocolate cream 1 and chocolate cream 2. Chocolate cream 1 and 2 respectively takes 50g in 100ml beaker, is placed on 50 DEG C of baking ovens, observes the precipitation situation of surface grease.

As the result is shown in Fig. 1.The results show that chocolate cream 1 is without obvious grease precipitation (right figure), chocolate cream 2 after 3 weeks There is a little grease that (left figure) is precipitated.
