sorbic acid and a
เกลือของมัน, propionic acid and a เกลือของมัน, benzoic acid and a เกลือของมัน, an amino acid, and nisin with inulin and optionally
with a pH adjuster. The prepared เสเส
may be formulated as powder or liquid by the use of a method or apparatus known in the art, such as double cone blender, nauta mixer, paddle mixer and homomixer.
The เสเส for food product of the present การประดิษฐ์ can be added to a food product without using any special operation. For example, the เสเส in the form of powder or liquid may be added to the food product and
optionally mixed. When it is applied to a processed food product,
it may be mixed with the ingredients. The amount of the
composition to be added is not specifically limited and may be
determined on the basis of the formulation of the shelf life
improver composition, types of the food product to be added with the composition, the desired shelf life improving effect and the effect on the taste of the food product.

In a preferred embodiment, the เสเส for food product ซึ่งประกอบรวมด้วย at least one สารยับยั้งแบคทีเรีย
selected from the group consisting of อะซิเตต, sorbic acid and a
เกลือของมัน, propionic acid and a เกลือของมัน, benzoic acid and a เกลือของมัน and an amino acid is added to the food product so that
the ratio of the total สารยับยั้งแบคทีเรีย will be 0.01 to 10
wt%, ที่ควรใช้กว่าคือ 0.05 to 5 wt% and even ที่ควรใช้กว่าคือ 0.1 to
3 wt% ที่คิดจากน้ำหนักรวม of the food product added with the
composition. For example, a เสเส
ซึ่งประกอบรวมด้วย 50 to 80 wt% of sodium อะซิเตต as a ยับยั้งแบคทีเรีย
substance may be added to a food product in an amount of 0.1 to 5
wt%, ที่ควรใช้คือ 0.2 to 3 wt% and ที่ควรใช้กว่าคือ 0.3 to 2 wt% based
on the total weight of the food product.
In another embodiment, the เสเส for food
product ซึ่งประกอบรวมด้วย a nisin may be added to a food product so that
the ratio of the nisin would be 0.000001 to 0.1 wt%, ที่ควรใช้คือ
0.000005 to 0. 05 wt%, and ที่ควรใช้กว่าคือ 0.00001 to 0.03 wt%
ที่คิดจากน้ำหนักรวม of the food product. For example, a
เสเส ซึ่งประกอบรวมด้วย 0.01 to 1 wt% of nisin A
as a สารยับยั้งแบคทีเรีย may be added to a food product in an amount of 0.1 to 3wt%, ที่ควรใช้คือ 0.3 to 2 wt% and ที่ควรใช้กว่าคือ
0.5 to 1 wt% ที่คิดจากน้ำหนักรวม of the food product. [0044]

applied to fish paste products, such as kamaboko (fish cake ) ,
chikuwa (tube- shaped fish paste), hanpen (steamed fish cake made
of fish past and starch), fish-meat ham and sausage; meat products such as ham, sausage, bacon, hamburger patty and meatball, fried food such as croquette, pork cutlet, fried chicken, fried fish and
karaage (deep-fried chicken), cooked rice such as fried rice and
takikomi-gohan (boiled rice cooked with various ingredients),
noodles such as Chinese noodle, pasta, udon noodle (Japanese wheat noodle) and buckwheat noodles, prepared foods such as potato salad, jiaozi(Chinese dumpling), shaomai(steamed meatball dumplings),
omelet, nimono(boiled dish), and aemono(vegetables with Japanese
dressing), filling material such as that of curry bread (deep-fried bread with thickened curry filling inside), Chinese steamed buns
and sandwiches, cream such as custard cream, whipped cream and
flour paste, confectionary such as castella sponge cake, sponge
cake, manju (bun with bean- jam filling) and bean jam, processed
fruit such as jam, cheese such as processed cheese and beverage
such as fruit juice, vegetable drink, carbonated drink and tea.

Examples 1-3 and Comparative Example 1 Preparation of custard cream
To 51 g of whole egg stirred thoroughly, sugar 75 g and sifted
cornstarch 24 g were added and the mixture was further stirred.
Subsequently, 300 g of milk warmed to 65°C was added while
stirring. To the obtained mixture, the shelf life improver
compositions indicated in Table 1 were respectively added in an
amount of 1 wt% ที่คิดจากน้ำหนักรวม of the mixture. The
mixture was heated to 85°C while stirring and further stirred for 2
minutes at 85°C. After stopping heating, vanilla extract 0.5 g was
added to the mixture and the obtained mixture was stirred for 1 minute to provide custard cream. The obtained custard cream was cooled on ice and used in the following evaluation.

Sensory Evaluation
The custard cream prepared as described above was used in the
sensory evaluation for the harsh taste (acidic taste + bitter
taste) Sensory evaluation was performed by a panel of 13 people
in accordance with the criteria below. Custard cream with the
เสเส of Comparative Example 1 was used as control.
Criteria for evaluating harsh taste
(acidic taste + bitter taste)
+: less harsh than control
+: no significant difference
-: harsher than control
[0049]
In the custard cream with each of the shelf life improver
compositions of Examples 1 to 3, the harsh taste (acidic taste +
bitter taste) was weaker than control. The results are shown in
Table 2.

Preserving effect
The custard cream 300 g prepared with each of the shelf life
improver compositions for food product of Examples 1 to 3 and
Comparative Example 1 as described above was stored at 25°C in a
thermostat. Samples were collected at predetermined time points.
The general bacterial cell number was measured by the microbial limit test (petriplate method) as described in the Japanese
standard of food additives.
[0052]
When the เสเสs for food product of
Examples 1 to 3 were added to the custard cream, the growth of
general bacteria was suppressed even after 20 days of storage. It
demonstrates that the เสเสs of Example 1
to 3 showed greatly improved preserving effect compared to the
shelf life improver of the Comparative Example 1. The results are
shown in Table 3 and รูป 1.

Preparation of hamburger patties
Hamburg Helper (House Foods Corporation) 23 g was mixed with milk
120g and minced pork and beef 250 g. Subsequently, the shelf life
improver composition for food product indicated in Table 4 was
added to the mixture in an amount of 0.5 wt% ที่คิดจาก total
weight of the obtained mixture. After sufficient mixing, about 20
g of the mixture was each shaped into a patty. The patties were
cooked at 230°C for 4 minutes in a preheated steam convection oven
(Tanico Corporation). The obtained hamburger patties were cooled
at room temperature and then used in the following evaluation. [0055]
