Description
Technical field
The present invention relates to a kind of fat or oil composition, concrete, relate to the fat or oil composition that a kind of ductility is good, described fat or oil composition can be used as Conventional application techniques etc..
Background technology
Coating process is commonly used for the impact from external environment condition such as moisture content etc. of the protection food in the food industry.Food quality is brought many harmful effects by water translocation, for instance cause ice cream cone to lose fragility and chocolate core material is dry etc..Different oils and fatss are because of the difference of its physicochemical property and processing conditions, and its moisture permeable there are differences.In 2006, Martini etc. once reported that the moisture penetration performance of oils and fats and its stearic acid content were negative correlativing relation.The ability that the oils and fats barrier coat food that moisture permeable is stronger absorbs moisture is more weak.
When coating food products expands because of water suction, the poor oils and fats of ductility is easy to crack cause that food quality declines subsequently.Martini etc. report that the ductility of oils and fats and its rheological property have relation.The oils and fats ductility with relatively low storage modulu (G ') and higher fissipation factor (tan δ) is better and not easy to crack, thus can keep the integrity of coating, strengthens food and intercepts the ability of moisture.Correlation research currently for triglyceride composition with its moisture permeable and ductility have not been reported.
Water translocation method in suppression food has been formed Patents by the companies such as only liquefaction, Kraft and Uniliver all.Only liquefaction has been invented in a kind of frozen food coating oils and fats (SUU+SUS >=40%, 0.3≤SUU/SUS≤3.0).This fat or oil composition can prevent the water translocation in polynary food system, but it needs to add glycerol monostearate to promote crystalline rate and to receive dry (US5766659B).Kraft has invented a kind of edible waterproof coating, and it is by the sugar (50-90%) of highly crystalline, oils and fats (10-50%), and cellulose (0.1-30%) composition (US2004/0197446).Its rapid crystallization characteristic causes coating at high temperature to carry out to form the effect that waterproof migrates.The edible coating that Uniliver invents contains chitosan complexes, and this coating can delay ice cream cone to lose fragility.
Prior art does not also occur a kind of can promote ductility cracking resistance simultaneously and there is the good oils and fats preventing water translocation.

Moisture permeable is tested
The fat or oil composition of the present invention and the moisture permeable test of comparative example fat or oil composition detect in accordance with the following methods: respectively 3% (w/w) gelatin, 30% glycerol (w/w) (purity 99.5%) and 67% (w/w) aqueous solution containing 100ppm potassium sorbate are thoroughly mixed to take gross weight ratio.Continuously stirred for this mixed solution heating to 70 DEG C and is maintained 15min, takes this mixed liquor of 15g equably in rectangular box (36mm*58mm*25mm), be immediately transferred in 5 DEG C of refrigerators and keep 1h until gel is fully cured.This method gained colloid internal relative humidity is 90%.The fat or oil composition of the present invention and comparative example fat or oil composition are completely melt at 70 DEG C, when oils and fats is cooled to 40 DEG C, take about 3.5g oil sample and be uniformly coated on above-mentioned completely crued gel surface, form oil layer.Oil layer cools down (8 DEG C of cooling 40mins, 15 DEG C of cooling 20mins) through following procedure.In cooling procedure, the fat or oil composition of the same race of the gap liquid between rectangular box and oil layer is filled with a sealing.So far, weigh and record the weight of whole rectangular box.The rectangular box prepared is transferred in drying basin (in ware relative humidity 3.5%), records the weight change of rectangular box every 24h.Moisture permeable computational methods are as follows:
Moisture penetration rate Watervaportransmissionrate (WVTR)=slope/A
Moisture permeable WVP (gmmdays-1cm-2mmHg-1)=
WVTR(gdays-1cm-2)·△X(mm)/△P(mmHg)
=slope △ X/ (A △ P)
Wherein:
Slope: rectangular box loss of water every day weight (gdays-1) (every day loss of water weight amount: monitoring 5 days continuously, takes the data point of five days, adds Trendline according to scatterplot and obtains slope, as fluid loss every day)；
A: film area (cm2)；
△ X: oil film thickness (mm)；
△ P: the steam pressure difference (mmHg is the vapour pressure under corresponding room temperature by the relative humidity inside and outside the gel that converts, calculates and obtain steam pressure difference) of oil film both sides.
